获取 app\_conf 对象后,可以直接用 [object](fscript_object.md) 的接口访问 app\_conf。
### 1. app_conf
> 获取 app_conf 对象
----------------------------
#### 原型
2022-08-23 10:12:36 +08:00
```js
2021-01-13 15:42:09 +08:00
app_conf() => object
2021-01-11 12:12:59 +08:00
```
#### 示例
2022-08-23 10:12:36 +08:00
```js
2021-01-11 12:12:59 +08:00
assert(object_set(app_conf(), "timeout", 100))
```
### 2. app_conf_save
> 保存修改。
----------------------------
#### 原型
2022-08-23 10:12:36 +08:00
```js
2021-01-13 15:42:09 +08:00

assert(app_conf_save())
```
### 完整示例
```js
assert(object_set(app_conf(), "timeout", 100))
assert(object_set(app_conf(), "serial.device", "/dev/tty01"))
assert(object_set(app_conf(), "serial.baudrate", 115200))
assert(app_conf_save())
assert(object_get(app_conf(), "timeout") == 100)
assert(object_get(app_conf(), "serial.device") == "/dev/tty01")
assert(object_get(app_conf(), "serial.baudrate") == 115200)
assert(object_remove(app_conf(), "timeout"))
assert(object_remove(app_conf(), "serial"))
assert(object_get(app_conf(), "timeout", 10) == 10)
assert(object_get(app_conf(), "serial.device", "a") == "a")
assert(object_get(app_conf(), "serial.baudrate", 1000) == 1000)
assert(object_set(app_conf(), "timeout", 100))
assert(app_conf_save())
```
