flutter - 如何在 Flutter 中使用 Dio 处理超时错误?

我正在使用 Dio 来处理 API 功能。

这是我的代码:

  Future<List<ItemModel>> getItems() async {
try {
Response response = await dio.get("$_apiUrl$_itemEndPoint",
options: Options(headers: {
"Accept": 'application/json',
}));

List<ItemModel> _items = List<ItemModel>();

response.data['data']?.forEach((c) {
_items.add(ItemModel.fromMap(c));
});
return _items;
} catch (e) {
throw (e);
}
}

如何根据发送和接收超时捕获错误?

最佳答案

使用 dio 管理超时异常:

ApiRepositary.dart

 class ApiRepositary {
Dio dio;

ApiRepositary() {
if (dio == null) {
BaseOptions options = new BaseOptions(
baseUrl: "your base url",
receiveDataWhenStatusError: true,
connectTimeout: 60*1000, // 60 seconds
receiveTimeout: 60*1000 // 60 seconds
);

dio = new Dio(options);
}
}

Future<LoginResponse> getLoginDetails(var loginRequestData) async {
try {
Response response = await dio.post("/authenticate", data: loginRequestData);
final LoginResponse loginResponse = LoginResponse.fromJson(response.data);
return loginResponse;
}on DioError catch (ex) {
if(ex.type == DioErrorType.CONNECT_TIMEOUT){
throw Exception("Connection Timeout Exception");
}
throw Exception(ex.message);
}
}

}

句柄异常示例:
void checkLogin(){
LoginRequest loginRequest = new LoginRequest(
email: "abcd@gmail.com",password: "passs@123");

var requestBody =jsonEncode(loginRequest);
debugPrint("Request Data : $requestBody");

_apiRepositary.getLoginDetails(requestBody).then((response){
debugPrint("Login Success $response");
//manage your response here

},
onError: (exception){
//Handle exception message
if(exception.message != null ){

debugPrint(exception.message); // Here you get : "Connection Timeout Exception"

}
},
);
}
