flutter niu_links使用
dio: ^3.0.6
uni_links: ^0.4.0
1，dio的使用，并且二次封装，还设置了抓包代理

使用的时候的代码：
//get获取
void getDioList(String string, String method, String sid) {
///显示指定Map的限定类型 ?page=1&count=2&type=video
//在super.initState(); 写
// FormData formData = new FormData.from({
// "uuid": "9dad1c81889ff0ea8c8c5ade6a5e36e3",
// "sign": "",
// "sso_id": "",
// "own_version": "100",
// "channel": "ios",
// "dev_os_version": "iOS12.3.1",
// "timestamp": "1564974676",
// "screen_size": "[375,667]",
// "is_jailbreak": 0,
// "os": "ios",
// "device_name": "iPhone6S",
// "os_version": "",
// "country_code": "CN",
// "ios_version": "1.0.0",
// });
Map parms = {'name': '$sid'}; //{"page": "1", "count": "2", "type": "video"};
Map headers = {};
DioUtils.dioHttp(
string,
headers,
method,
params: parms,
onSuccess: (data) {
print("成功：" + data.toString());
//反序列化
Map jsonMsg = json.decode(data.toString());
Autogenerated autogenerated = Autogenerated.fromJson(jsonMsg);
//序列化
String date = json.encode(autogenerated);
//更新ui
setState(() {
respons = autogenerated.result.toString();
});
},
onError: (error) {
print("成功：" + error.toString());
setState(() {
respons = error.toString();
});
},
);
} 顺便拿到的数据还序列化了，https://javiercbk.github.io/json_to_dart/ 这个网站也可以反序列化实例
2，niu_links学习：
先配置Android
ios的配置：info.plist
CFBundleURLTypes
CFBundleTypeRole
Editor
CFBundleURLName
com.example.uniLinksExample
CFBundleURLSchemes
unilinks
配置Runner，新建文件，
main.dart文件：

}; 中转html文件代码，记得把自己的hosts和scheme配置上。

建议dio和niu_links配合官方文档和我的代码看，就是一整套，官方文档给的只是小例子，不够用。
