Flutter网络请求篇-dio-retrofit

flutter  retrofit plug网址 https://pub.dev/packages/retrofit

创建抽象类

@RestApi(baseUrl: 'http://www.devio.org')
abstract class Http{
  factory Http(Dio dio,{String baseUrl}) = _HttpClient;

  @GET('/io/flutter_app/json/home_page.json')
  Future<HomeModel> getHomeDate();

  @GET('/restapi/h5api/searchapp/search')
  Future getSearch(@Query('source') String source,
      @Query('action') String action,
      @Query('contentType') String contentType,
      @Query('keyword') String keyword,);
}

具体类

class _HttpClient implements Http{
    _HttpClient(this._dio,{this.baseUrl}){
      ArgumentError.checkNotNull(_dio,'dio');
      this.baseUrl ??= 'http://www.devio.org';}
    final Dio _dio;
    String baseUrl;

  @override
  Future<HomeModel> getHomeDate() async {
    // TODO: implement getHomeDate
    final Response response =await _dio.request('/io/flutter_app/json/home_page.json',
      options: RequestOptions(method: 'GET', baseUrl: baseUrl));
    return HomeModel.formJson(response.data);
  }

  @override
  Future getSearch(String source, String action, String contentType, String keyword) async{
    // TODO: implement getSearch
    final Response response = await _dio.request('/restapi/h5api/searchapp/search',
      options: RequestOptions(method: 'GET',baseUrl: baseUrl)
    );
    return response.data;
  }

方法调用

initDate() async {
   await Http(widget.dio).getHomeDate().then((value){
     setState(() {
       homeModel = value;
     });
   });
}

flutter retrofit @Query 传参

final queryParameters =<String,dynamic>{
  'source' : source,
  'action' : action,
  'contentType' : contentType,
  'keyword' : keyword
};

然后在

final Response response = await dio.request('/restapi/h5api/searchapp/search',
  options: RequestOptions(method: 'GET',baseUrl: baseUrl,queryParameters: queryParameters)
);
