# EasyFlash Types 插件（plugin）
|
||||
|
||||
---
|
||||
|
||||
## 1、介绍
|
||||
|
||||
目前 EasyFlash 会将环境变量以字符串形式存储于 Flash 中，在这种模式下，对于非字符串类型的环境变量在使用时，就必须得增加额外的字符串转换代码。设计 Types 插件就是为了方便用户在使用 EasyFlash 时，以更加简单的方式去操作各种类型的环境变量。
|
||||
|
||||
主要支持的类型包括：C 的 **基本类型** 、 **数组类型** 以及 **结构体类型** 。对于结构体类型， Types 插件内部采用 [struct2json](https://github.com/armink/struct2json) 库进行转换，所以项目中需要依赖 [struct2json](https://github.com/armink/struct2json) 库。
|
||||
|
||||
## 2、使用
|
||||
|
||||
### 2.1 源码导入
|
||||
|
||||
导入之前需要确认自己的项目中已包含 EasyFlash 核心源码，即包括 "\easyflash\inc"、"\easyflash\port" 及 "\easyflash\src" 下相关文件（导入方法可以参考这个移植文档：[点击打开](https://github.com/armink/EasyFlash/blob/master/docs/zh/port.md)）。再将 Types 插件源码导入到项目中，最好连同 "plugins\types" 文件夹一起拷贝至项目中已有的 easyflash 文件夹下。然后需要添加 `easyflash\plugins\types\struct2json\inc` 及 `easyflash\plugins\types` 两个文件夹路径到项目头文件路径中即可。
|
||||
|
||||
### 2.2 初始化
|
||||
|
||||
```C
|
||||
void ef_types_init(S2jHook *hook)
|
||||
```
|
||||
|
||||
这个方法为 Types 插件的初始化方法，主要初始化 struct2json 库所需的内存管理方法。默认使用的 malloc 及 free 作为内存管理方法，如果使用默认内存管理方式，则无需初始化。例如如果使用 RT-Thread 操作系统自带的内存管理方法，则可以参考下面的初始化代码：
|
||||
|
||||
```C
|
||||
S2jHook s2jHook = {
|
||||
.free_fn = rt_free,
|
||||
.malloc_fn = (void *(*)(size_t))rt_malloc,
|
||||
};
|
||||
ef_types_init(&s2jHook);
|
||||
```
|
||||
|
||||
### 2.3 操作环境变量
|
||||
|
||||
#### 2.3.1 基本类型
|
||||
|
||||
对于基本类型的环境变量操作方法与 EasyFlash 原有的 API 一致，只是修改了入参及出参的类型，所有可用的 API 如下：
|
||||
|
||||
```
|
||||
bool ef_get_bool(const char *key);
|
||||
char ef_get_char(const char *key);
|
||||
short ef_get_short(const char *key);
|
||||
int ef_get_int(const char *key);
|
||||
long ef_get_long(const char *key);
|
||||
float ef_get_float(const char *key);
|
||||
double ef_get_double(const char *key);
|
||||
EfErrCode ef_set_bool(const char *key, bool value);
|
||||
EfErrCode ef_set_char(const char *key, char value);
|
||||
EfErrCode ef_set_short(const char *key, short value);
|
||||
EfErrCode ef_set_int(const char *key, int value);
|
||||
EfErrCode ef_set_long(const char *key, long value);
|
||||
EfErrCode ef_set_float(const char *key, float value);
|
||||
EfErrCode ef_set_double(const char *key, double value);
|
||||
```
|
||||
|
||||
#### 2.3.2 数组类型
|
||||
|
||||
与基本类型的操作方法大体一致，不同点在于：获取到的环境变量需通过指针类型的入参进行返回。所有可用的 API 如下：
|
||||
|
||||
```C
|
||||
void ef_get_bool_array(const char *key, bool *value);
|
||||
void ef_get_char_array(const char *key, char *value);
|
||||
void ef_get_short_array(const char *key, short *value);
|
||||
void ef_get_int_array(const char *key, int *value);
|
||||
void ef_get_long_array(const char *key, long *value);
|
||||
void ef_get_float_array(const char *key, float *value);
|
||||
void ef_get_double_array(const char *key, double *value);
|
||||
void ef_get_string_array(const char *key, char **value);
|
||||
EfErrCode ef_set_bool_array(const char *key, bool *value, size_t len);
|
||||
EfErrCode ef_set_char_array(const char *key, char *value, size_t len);
|
||||
EfErrCode ef_set_short_array(const char *key, short *value, size_t len);
|
||||
EfErrCode ef_set_int_array(const char *key, int *value, size_t len);
|
||||
EfErrCode ef_set_long_array(const char *key, long *value, size_t len);
|
||||
EfErrCode ef_set_float_array(const char *key, float *value, size_t len);
|
||||
EfErrCode ef_set_double_array(const char *key, double *value, size_t len);
|
||||
EfErrCode ef_set_string_array(const char *key, char **value, size_t len);
|
||||
```
|
||||
#### 2.3.3 结构体类型
|
||||
|
||||
对于结构体类型，这里首先需要使用 struct2json 库来编写与该结构体对应的 JSON 互转方法，再将编写好的互转方法作为入参进行使用。结构体类型环境变量操作的 API 如下：
|
||||
|
||||
```C
|
||||
void *ef_get_struct(const char *key, ef_types_get_cb get_cb);
|
||||
EfErrCode ef_set_struct(const char *key, void *value, ef_types_set_cb set_cb);
|
||||
```
|
||||
|
||||
具体使用流程及结构体与 JSON 之间的互转方法可以参考下面的 Demo：
|
||||
|
||||
```C
|
||||
/* 定义结构体 */
|
||||
typedef struct {
|
||||
char name[16];
|
||||
} Hometown;
|
||||
typedef struct {
|
||||
uint8_t id;
|
||||
double weight;
|
||||
uint8_t score[8];
|
||||
char name[16];
|
||||
Hometown hometown;
|
||||
} Student;
|
||||
|
||||
/* 定义结构体转 JSON 的方法 */
|
||||
static cJSON *stu_set_cb(void* struct_obj) {
|
||||
Student *struct_student = (Student *)struct_obj;
|
||||
/* 创建 Student JSON 对象 */
|
||||
s2j_create_json_obj(json_student);
|
||||
/* 序列化数据到 Student JSON 对象 */
|
||||
s2j_json_set_basic_element(json_student, struct_student, int, id);
|
||||
s2j_json_set_basic_element(json_student, struct_student, double, weight);
|
||||
s2j_json_set_array_element(json_student, struct_student, int, score, 8);
|
||||
s2j_json_set_basic_element(json_student, struct_student, string, name);
|
||||
/* 序列化数据到 Student.Hometown JSON 对象 */
|
||||
s2j_json_set_struct_element(json_hometown, json_student, struct_hometown, struct_student, Hometown, hometown);
|
||||
s2j_json_set_basic_element(json_hometown, struct_hometown, string, name);
|
||||
return json_student;
|
||||
}
|
||||
|
||||
/* 定义 JSON 转结构体的方法 */
|
||||
static void *stu_get_cb(cJSON* json_obj) {
|
||||
/* 创建 Student 结构体对象（提示： s2j_ 开头的方法是 struct2json 库提供的） */
|
||||
s2j_create_struct_obj(struct_student, Student);
|
||||
/* 反序列化数据到 Student 结构体对象 */
|
||||
s2j_struct_get_basic_element(struct_student, json_obj, int, id);
|
||||
s2j_struct_get_array_element(struct_student, json_obj, int, score);
|
||||
s2j_struct_get_basic_element(struct_student, json_obj, string, name);
|
||||
s2j_struct_get_basic_element(struct_student, json_obj, double, weight);
|
||||
/* 反序列化数据到 Student.Hometown 结构体对象 */
|
||||
s2j_struct_get_struct_element(struct_hometown, struct_student, json_hometown, json_obj, Hometown, hometown);
|
||||
s2j_struct_get_basic_element(struct_hometown, json_hometown, string, name);
|
||||
return struct_student;
|
||||
}
|
||||
|
||||
/* 设置结构体类型环境变量 */
|
||||
Student orignal_student = {
|
||||
.id = 24,
|
||||
.weight = 71.2,
|
||||
.score = {1, 2, 3, 4, 5, 6, 7, 8},
|
||||
.name = "张三",
|
||||
.hometown.name = "北京",
|
||||
};
|
||||
ef_set_struct("张三学生", &orignal_student, stu_set_cb);
|
||||
|
||||
/* 获取结构体类型环境变量 */
|
||||
Student *student;
|
||||
ef_get_struct("张三学生", student, stu_get_cb);
|
||||
|
||||
/* 打印获取到的结构体内容 */
|
||||
printf("姓名：%s 籍贯：%s \n", student->name, student->hometown.name);
|
||||
|
||||
/* 释放获取结构体类型环境变量过程中开辟的动态内存 */
|
||||
s2jHook.free_fn(student);
|
||||
```

# C结构体与 JSON 快速互转库
|
||||
|
||||
---
|
||||
|
||||
## struct2json
|
||||
|
||||
[struct2json](https://github.com/armink/struct2json) 是一个开源的C结构体与 JSON 快速互转库，它可以快速实现 **结构体对象** 与 **JSON 对象** 之间序列化及反序列化要求。快速、简洁的 API 设计，大大降低直接使用 JSON 解析库来实现此类功能的代码复杂度。
|
||||
|
||||
## 起源
|
||||
|
||||
把面向对象设计应用到C语言中，是当下很流行的设计思想。由于C语言中没有类，所以一般使用结构体 `struct` 充当类，那么结构体变量就是对象。有了对象之后，很多时候需要考虑对象的序列化及反序列化问题。C语言不像很多高级语言拥有反射等机制，使得对象序列化及反序列化被原生的支持。
|
||||
|
||||
对于C语言来说，序列化为 JSON 字符串是个不错的选择，所以就得使用 [cJSON](https://github.com/kbranigan/cJSON) 这类 JSON 解析库，但是使用后的代码冗余且逻辑性差，所以萌生对cJSON库进行二次封装，实现一个 struct 与 JSON 之间快速互转的库。 struct2json 就诞生于此。下面是 struct2json 主要使用场景：
|
||||
|
||||
- **持久化** ：结构体对象序列化为 JSON 对象后，可直接保存至文件、Flash，实现对结构体对象的掉电存储；
|
||||
- **通信** ：高级语言对JSON支持的很友好，例如： Javascript、Groovy 就对 JSON 具有原生的支持，所以 JSON 也可作为C语言与其他语言软件之间的通信协议格式及对象传递格式；
|
||||
- **可视化** ：序列化为 JSON 后的对象，可以更加直观的展示到控制台或者 UI 上，可用于产品调试、产品二次开发等场景；
|
||||
|
||||
## 如何使用
|
||||
|
||||
### 声明结构体
|
||||
|
||||
如下声明了两个结构体，结构体 `Hometown` 是结构体 `Student` 的子结构体
|
||||
|
||||
```C
|
||||
/* 籍贯 */
|
||||
typedef struct {
|
||||
char name[16];
|
||||
} Hometown;
|
||||
|
||||
/* 学生 */
|
||||
typedef struct {
|
||||
uint8_t id;
|
||||
uint8_t score[8];
|
||||
char name[10];
|
||||
double weight;
|
||||
Hometown hometown;
|
||||
} Student;
|
||||
```
|
||||
|
||||
### 将结构体对象序列化为 JSON 对象
|
||||
|
||||
|未使用（[源文件](https://github.com/armink/struct2json/blob/master/docs/zh/assets/not_use_struct2json.c)）|使用后（[源文件](https://github.com/armink/struct2json/blob/master/docs/zh/assets/used_struct2json.c)）|
|
||||
|:-----:|:-----:|
|
||||
|| |
|
||||
|
||||
### 将 JSON 对象反序列化为结构体对象
|
||||
|
||||
|未使用（[源文件](https://github.com/armink/struct2json/blob/master/docs/zh/assets/not_use_struct2json_for_json.c)）|使用后（[源文件](https://github.com/armink/struct2json/blob/master/docs/zh/assets/used_struct2json_for_json.c)）|
