Flutter笔记-Dio使用

Dio简单入门

首先需要在pubspec.yaml 里面的dependencies: 里面配置如下:

dependencies:
  flutter:
    sdk: flutter

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  dio: ^3.0.9

代码中使用如下:

 RaisedButton(
              child: Text('下一步'),
              onPressed: (){             
                getData();       
              })

 getData() async{
   var url = "http://www.mocky.io/v2/5e709ddb3000006a007a3025";
   try{
     Response response = await Dio().get(url);
     print(response.data['code']);
     print(response.data['data']['name']);
   }catch(e){
     return print(e);
   }
 }

输出:
I/flutter ( 8886): 200
I/flutter ( 8886): hello world

这是get访问，同理其他访问如下:

Performing a POST request:

response = await dio.post("/test", data: {"id": 12, "name": "wendu"});

Performing multiple concurrent requests:

response = await Future.wait([dio.post("/info"), dio.get("/token")]);

Downloading a file:

response = await dio.download("https://www.google.com/", "./xx.html");
