AFNetworking 3.0 The data couldn’t be read because it isn’t in the correct format

问题:

There are other questions with similar titles but none of them helped me. I've to send a PUT request to server in order to change the status of appointment so I've made this method -(void)appointmentStatusChangedTo:(NSString *)statusID atAppointmentID:(NSString *)appointmentID In which I'm setting the URL and Parameters as

NSString *string = [NSString stringWithFormat:@"%@/API/Appointments/3",BaseURLString];     NSDictionary *para = @{                            @"AppointmentStatusId":statusID,                            @"ID":appointmentID                            }; 

Then I've made URL request as

AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];      NSMutableURLRequest *req = [[AFJSONRequestSerializer serializer] requestWithMethod:@"PUT" URLString:string parameters:para error:nil]; 

After that I'm setting the header for an authorization token as

 NSString *token = [NSString stringWithFormat:@"Bearer %@",[[NSUserDefaults standardUserDefaults] objectForKey:@"userToken"]];      [req setValue:token forHTTPHeaderField:@"Authorization"]; 

So finally I'm calling it as

[[manager dataTaskWithRequest:req completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error){         if (!error) {             if (response) {                 NSLog(@"Respose Object: %@",responseObject);                 [self.patientsAppointmentsTableView reloadData];             }         }         else {     // NSLog(@"Error: %@, %@, %@", error, response, responseObject);     NSLog(@"Error: %@", error.localizedDescription); }         }] resume]; 

Now it is successfully sending the data to the server but as a response I'm getting

Error: The data couldn’t be read because it isn’t in the correct format.

I am not sure what the response might look like at the moment as I'm not in contact with backend guy. But as far as I remember it was just a simple 1. SO kindly tell me how to handle any type of response using AFNetworking 3.0 or any change in my code.

回答1:

try to use below code:

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];  AFJSONRequestSerializer *serializer = [AFJSONRequestSerializer serializer]; [serializer setStringEncoding:NSUTF8StringEncoding];  manager.requestSerializer=serializer; manager.responseSerializer = [AFHTTPResponseSerializer serializer]; 

回答2:

Try following code using Afnetworking 3.0

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];     manager.responseSerializer = [AFJSONResponseSerializer serializer];     [manager GET:url parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {         NSLog(@"%@",responseObject);         self.responseHandlers(YES,responseObject);     } failure:^(NSURLSessionTask *operation, NSError *error) {         self.responseHandlers(NO,nil);     }];
