我在使用 API 进行身份验证或登录时遇到 HTTP 错误 500。并且无法收到此错误。它之前运行良好,但突然向我抛出了这个 HTTP 错误。
代码:
Dio 类的实例:
dio() {
Dio dio = Dio();
dio.options.connectTimeout = 60000; //5s
dio.options.receiveTimeout = 60000;
return dio;
}
鉴定方法:
Future<Map> authenticate({@required String username, @required String password}) async{
String url = "https://.....";
Response response;
try{
response =await dio().post(
url,
options: Options(
contentType: ContentType.parse("application/x-www-form-urlencoded"),
),
data: {
'grant_type': 'password',
'client_id':clientId,
'client_secret':clientSecret,
'username': username,
'password': password,
}
);
print("Authentication post response.dataaaaaa:${response.data}");
return response.data;
}catch(e){
print("ERROR:$e");
throw e;
}
}
在 catch 块中出现错误:
DioError [DioErrorType.RESPONSE]: Http status error [500]
