# Introduction
***

DrissionPage, the combination of driver and session, is a Python-based Web automation operation integration tool.  
It integrates selenium and requests_html to achieve seamless switching between them.  
Therefore, the convenience of selenium and the high efficiency of requests can be considered.  
It encapsulates commonly used methods of page elements and is very suitable for the expansion of the PO mode of automated operation.  
Even better, it is very concise and user-friendly, with little code and friendly to novices.

# Features

***

-Allows seamless switching between selenium and requests, sharing session.
-The two modes provide a unified operation method with consistent user experience.
-Common methods are encapsulated in units of pages to facilitate PO mode expansion.
-Humanized operation method of page elements to reduce the workload of page analysis and coding.
-Save configuration information to file for easy recall.
-Some common functions (such as click) have been optimized to better meet the actual needs.

# Idea

## Simple, Easy and Extensible

- DrissionPage takes concise code as the first pursuit, streamlines long statements and completely retains its functions.
- DrissionPage encapsulates many commonly used functions and is more convenient to use.
- The core of DrissionPage is a page class, which can directly derive subclass pages to adapt to various scenarios.

The following code implements exactly the same function, comparing the code amounts of the two:

1、Find all elements whose name is ele_name

```python
# selenium:
element = WebDriverWait(driver).until(ec.presence_of_all_elements_located((By.XPATH, '//*[@name="ele_name"]')))
# DrissionPage:
element = page.eles('@name:ele_name')
```

2、Find the element whose first text contains 'some text'

```python
# selenium:
element = WebDriverWait(driver, timeout = 2).until(ec.presence_of_element_located((By.XPATH, '//*[contains(text(), "some text")]')))
# DrissionPage:
element = page.ele('some text', timeout = 2)
```

3、Jump to the first tab

```python
# selenium
driver.switch_to.window(driver.window_handles[0])
# DrissionPage
page.to_tab(0)
```

4、Drag an element

```python
# selenium
ActionChains(driver).drag_and_drop(ele1, ele2).perform()
# DrissionPage
ele1.drag_to(ele2)
```

# Background

***

When a novice learns a web crawler, in the face of a website that needs to log in, it is necessary to analyze data packets, JS source code, construct complex requests, and often have to deal with verification codes, JS confusion, signature parameters and other measures, which is difficult to learn. When acquiring data, some data is generated by JavaScript calculation. If you only get the source data, you must also reproduce the calculation process. The experience is not good and the development efficiency is not high.

Using selenium can avoid these problems to a great extent, but selenium is not efficient. Therefore, what this library has to do is to combine selenium and requests into one, and provide a humanized use method to improve development and operation efficiency.

In addition to merging the two, this library also encapsulates commonly used functions in units of web pages, which simplifies selenium operations and statements. When used in web page automation operations, it reduces the consideration of details, focuses on function implementation, and is more convenient to use.

The design concept of this library is to keep everything simple, try to provide a simple and direct method of use, and is more friendly to novices.

# Simple Demo

***

Example: Log in to the website with selenium, then switch to requests to read the web page.

```python
drission = Drission()  # Create Drive Object
page = MixPage(drission)  # Create page object, default driver mode
page.get('https://gitee.com/profile')  # Visit personal center page (redirect to the login page)

page.ele('@id:user_login').input('your_user_name')  # Use selenium to log in
page.ele('@id:user_password').input('your_password\n')

page.change_mode()  # Switch to session mode
print('Title after login:', page.title, '\n')  # Output of session mode after login
```

Output:

```
Title after login: Dashboard - Gitee
```

Example: Find element and print attributes.

```python
foot = page.ele('@id:footer-left')  # Find elements by id
first_col = foot.ele('css:>div')  # Find first div element in the lower level by css selector.
lnk = first_col.ele('text:Git Branching')  # Find elements by text content
text = lnk.text  # Get element text
href = lnk.attr('href')  # Get element attribute value

print(first_col)
print(text, href)
```

Output:

```
<SessionElement div class='column'>

```

# Install

***

```
pip install DrissionPage
```
Only python3.6 and above are supported. Driver mode currently only supports chrome.  
To use the driver mode, you must download chrome and ** corresponding version ** of chromedriver. [chromedriver download](https://chromedriver.chromium.org/downloads)  
Currently only tested in the Windows environment.

# Instructions

***

## import

```python
from DrissionPage import *
```



## Initialization

Before using selenium, you must configure the path of chrome.exe and chromedriver.exe and ensure that their versions match.

If you only use session mode, you can skip this section.

There are three ways to configure the path:

-Write two paths to system variables.
-Pass in the path manually when using it.
-Write the path to the ini file of this library (recommended).

If you choose the third method, please run these lines of code before using the library for the first time, and record these two paths in the ini file.

```python
from DrissionPage.easy_set import set_paths
driver_path = 'C:\\chrome\\chromedriver.exe'  # Your chromedriver.exe path, optional
chrome_path = 'D:\\chrome\\chrome.exe'  # Your chrome.exe path, optional
set_paths(driver_path, chrome_path)
```

This method also checks if the chrome and chromedriver versions match, and displays:

```
版本匹配，可正常使用。

or

出现异常：
Message: session not created: Chrome version must be between 70 and 73
  (Driver info: chromedriver=73.0.3683.68 (47787ec04b6e38e22703e856e101e840b65afe72),platform=Windows NT 10.0.19631 x86_64)
chromedriver下载网址：https://chromedriver.chromium.org/downloads
```

After the inspection is passed, the driver mode can be used normally.

In addition to the above two paths, this method can also set the following paths:

```python
debugger_address  # Opened browser address, eg. 127.0.0.1:9222
download_path  # Download path
global_tmp_path  # Temporary folder path
```

Tips：

-Different projects may require different versions of chrome and chromedriver. You can also save multiple ini files to use as needed.
-It is recommended to use the green version of chrome, and manually set the path to avoid browser upgrades that do not match the chromedriver version.
-It is recommended to set debugger_address when debugging a project, and use a manually opened browser to debug, saving time and effort.



## Create Drission Object 

Drission objects are used to manage driver and session objects. It can be created by directly reading the configuration information of the ini file, or it can be passed in during initialization.

```python
# Created by default ini file
drission = Drission()  

# Created by other ini files
drission = Drission(ini_path = 'D:\\settings.ini') 
```

To manually pass in the configuration:

```python
# Create with incoming configuration information (ignore ini file)
from DrissionPage.config import DriverOptions

driver_options = DriverOptions()  # Create driver configuration object
driver_options.binary_location = 'D:\\chrome\\chrome.exe'  # chrome.exe path
session_options = {'headers': {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6)'}}
driver_path = 'C:\\chrome\\chromedriver.exe'  # driver_path path

drission = Drission(driver_options, session_options, driver_path)  # Create object through incoming configuration
```



## Use MixPage objects

The MixPage page object encapsulates commonly used web page operations and implements the switch between driver and session mode.

```python
page = MixPage(drission)  # Default driver mode
page = MixPage(drission, mode='s', timeout=10)  # Session mode, element waiting time 5 seconds (default 10 seconds)

# Visit URL
page.get(url, **kwargs)
page.post(url, data, **kwargs)  # Only session mode has post method.Call the post method will automatically switch to session mode.

# Switch mode
page.change_mode()

# Page operation
print(page.html)  # Page source code
page.run_script(js)  # Run js statement
page.close_other_tabs(num)  # Close other tabs
page.to_iframe(iframe)  # switch to iframe
page.screenshot(path)  # Screenshot of the page
page.scrool_to_see(element)  # Scroll until an element is visible
# See APIs for details...
```

Tips：Calling a method that belongs only to the driver mode will automatically switch to the driver mode.



## Find elements

There are many ways to find page elements (eles function will return a list of all the element objects that meet the requirements).  

Note: The element search timeout is 10 seconds by default, you can also set it as required.

```python
# Find by attribute
page.ele('@id:ele_id', timeout = 2)  # Find the element with id ele_id and set the waiting time to 2 seconds
page.eles('@class:class_name')  # Find all elements with class class_name   

# Search by tag name
page.ele('tag:li')  # Find the first li element  
page.eles('tag:li')  # Find all li elements  

# Find by location
page.ele('@id:ele_id').parent  # Parent element  
page.ele('@id:ele_id').next  # Next sibling element  
page.ele('@id:ele_id').prev  # Previous brother element  

# Find by text
page.ele('search text')  # Find elements containing incoming text  
page.eles('text:search text')  # If the text starts with @, tag :, css :, xpath :, text :, add text: in front to avoid conflicts.  

# Find by xpath or css selector
page.eles('xpath://div[@class="ele_class"]')  
page.eles('css:div.ele_class')  

# Find by loc
loc1 = By.ID, 'ele_id'
loc2 = By.XPATH, '//div[@class="ele_class"]'
page.ele(loc1)
page.ele(loc2)

# Find subordinate elements
element = page.ele('@id:ele_id')
element.ele('@class:class_name')  # Find the first element whose class is ele_class at the lower level of element
element.eles('tag:li')  # Find all li elements below ele_id

# Tandem search
page.ele('@id:ele_id').ele('tag:div').next.ele('some text').eles('tag:a')
```



## Element operations

```python
# Get element information
element = page.ele('@id:ele_id')
element.html  # Return html inside element
element.text  # Returns the text value after removing the html tag in the element
element.tag  # Return element tag name
element.attrs  # Returns a dictionary of all attributes of the element
element.attr('class')  # Returns the element's class attribute
element.is_valid  # Driver mode only, used to determine whether the element is still available

# Operating element
element.click()  # Click element
element.input(text)  # Enter text
element.run_script(js)  # Run js
element.submit()  # submit Form
element.clear()  # Clear element
element.is_selected()  # Is selected
element.is_enabled()  # it's usable or not
element.is_displayed()  # Is it visible
element.is_valid()  # Whether it is valid, used to judge the situation where the page jump causes the element to fail
element.select(text)  # Select the drop-down list option
element.set_attr(attr,value)  # Set element attributes
element.size  # Returns the element size
element.location  # Returns the element position
```



## Save configuration

Because chrome and headers have many configurations, an ini file is set up to save commonly used configurations. You can use the OptionsManager object to get and save the configuration, and use the DriverOptions object to modify the chrome configuration. You can also save multiple ini files and call them according to different projects.

Tips：It is recommended to save common configuration files to another path to prevent the configuration from being reset when the library is upgraded.

### ini file

The ini file has three parts by default: paths, chrome_options, and session_options. The initial contents are as follows.

```ini
[paths]
; chromedriver.exe path
chromedriver_path =
; Temporary folder path, used to save screenshots, download files, etc.
global_tmp_path =

[chrome_options]
; The opened browser address and port, such as 127.0.0.1:9222
debugger_address =
; chrome.exe path
binary_location =
; Configuration information
arguments = [
            ; Hide browser window
            '--headless',
            ; Mute
            '--mute-audio',
            ; No sandbox
            '--no-sandbox',
            ; Google documentation mentions the need to add this attribute to avoid bugs
            '--disable-gpu'
            ]
; Plugin
extensions = []
; Experimental configuration
experimental_options = {
                       'prefs': {
                       ; Download without pop-up
                       'profile.default_content_settings.popups': 0,
                       ; No pop-up window
                       'profile.default_content_setting_values': {'notifications': 2},
                       ; Disable PDF plugin
                       'plugins.plugins_list': [{"enabled": False, "name": "Chrome PDF Viewer"}],
                       ; Set to developer mode, anti-anti-reptile (useless)
                       'excludeSwitches': ["ignore-certificate-errors", "enable-automation"],
                       'useAutomationExtension': False
                       }
                       }

[session_options]
headers = {
          "User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/603.3.8 (KHTML, like Gecko) Version/10.1.2 Safari/603.3.8",
          "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
          "Connection": "keep-alive",
          "Accept-Charset": "utf-8;q=0.7,*;q=0.7"
          }
```

### Usage example

```python
from DrissionPage import *
from DrissionPage.configs import *

driver_options = DriverOptions()  # Read configuration from default ini file
driver_options = DriverOptions('D:\\settings.ini')  # Read configuration from incoming ini file
driver_options.add_argument('--headless')  # Add configuration
driver_options.remove_experimental_options('prefs')  # Remove configuration
driver_options.save()  # Save configuration
driver_options.save('D:\\settings.ini')  # Save to other path

options_manager = OptionsManager()  # Create OptionsManager object
driver_path = options_manager.get_value('paths', 'chromedriver_path')  # Read path information
drission = Drission(driver_options, driver_path)  # Create a Drission object using configuration

drission = Drission(ini_path = 'D:\\settings.ini')  # Use other ini files to create objects
```

### OptionsManager object

The OptionsManager object is used to read, set, and save configurations.

```python
get_value(section, item) -> str  # Get the value of a configuration
get_option(section) -> dict  # Return all configuration properties in dictionary format
set_item(section, item, value)  # Set configuration properties
save()  # Save configuration to default ini file
save('D:\\settings.ini')  # Save to other path
```

** Note **: If you do not pass in the path when saving, it will be saved to the ini file in the module directory, even if you are not reading the default ini file.

### DriverOptions object

The DriverOptions object inherits from the Options object of selenium.webdriver.chrome.options, and adds the following methods to it:

```python
remove_argument(value)  # Delete an argument value
remove_experimental_option(key)  # Delete a experimental_option setting
remove_all_extensions()  # Remove all plugins
save()  # Save configuration to ini file
save('D:\\settings.ini')  # Save to other path
```


# PO mode

MixPage encapsulates common page operations and can be easily used for expansion.  

Example: Expand a list page reading class.

```python
import re
from time import sleep
from DrissionPage import *

class ListPage(MixPage):
    """This class encapsulates the method of reading the list page, according to the necessary 4 elements, can read the homogeneous list page"""

        self.xpath_total_pages = xpaths['total_pages']  # [xpath str, re str]
        self.total_pages = self.get_total_pages()
        if url:
            self.get(url)

    def get_cloumn_name(self) -> str:

## DriverPage and SessionPage

If there is no need to switch modes, only DriverPage or SessionPage can be used as required, the usage is consistent with MixPage.  

```python
from DrissionPage.session_page import SessionPage
from DrissionPage.drission import Drission

session = Drission().session
page = SessionPage(session)  # Pass in Session object
page.get('http://www.baidu.com')
print(page.ele('@id:su').text)  # Output：百度一下

driver = Drission().driver
page = DriverPage(driver)  # Pass in Driver object
page.get('http://www.baidu.com')
print(page.ele('@id:su').text)  # Output:百度一下
```

## MixPage class

class **MixPage**(drission: Drission, mode='d', timeout: float = 10)

MixPage encapsulates common functions for page operations and can seamlessly switch between driver and session modes. Cookies are automatically synchronized when switching.  
The function of obtaining information is common to the two modes, and the function of operating page elements is only available in the d mode. Calling a function unique to a certain mode will automatically switch to that mode.  
It inherits from DriverPage and SessionPage classes. These functions are implemented by these two classes. MixPage exists as a scheduling role.

Parameter Description:

### mode

​	Returns the current mode ('s' or 'd').

### drission

​	Returns the currently used Dirssion object.

### driver

​	Returns the driver object, if not created, it will switch to driver mode when called.

### session

​	Returns the session object, if not created.

### response

​	Return the Response object and switch to session mode when calling.

### cookies

​	Returns cookies, obtained from the current mode.

### html

​	Return the page html text.

### title

​	Return to the page title text.

### change_mode

​	change_mode(mode: str = None, go: bool = True) -> None

​	Jump to a url, sync cookies before jumping, and return whether the target url is available after jumping.

​	Parameter Description:

- url - Target url
- params - url parameters
- go_anyway - Whether to force a jump. If the target url is the same as the current url, the default is not to jump.
- kwargs - Used to access parameters when in session mode.

### ele

​	Get elements according to query parameters and return elements or element lists.  
​	If the query parameter is a string, you can select the '@property name:', 'tag:', 'text:', 'css:', 'xpath:' method. When there is no control mode, it is searched by text mode by default.  
​	If it is loc, query directly according to the content.

​	Parameter Description:
