AFNetworking 3.0无法读取数据，因为格式不正确 [英] AFNetworking 3.0 The data couldn’t be read because it isn’t in the correct format

问题描述

还有其他标题相似的问题，但没有一个对我有帮助。我必须向服务器发送一个 PUT 请求，以更改约会状态，因此我将这种方法设置为-（void）appointmentStatusChangedTo： （NSString *）statusID atAppointmentID：（NSString *）appointmentID 我在其中将URL和参数设置为

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
                           };

然后我已发出URL请求，

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];

之后，我将授权令牌的标头设置为

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"];

所以最后我将其称为

[[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];

现在它已成功将数据发送到服务器，但作为响应，我得到了

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

错误：由于数据格式不正确，无法读取数据。

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

由于我没有与后端人员联系，因此目前不确定响应会是什么样。但据我所知，这只是一个简单的1。所以，请告诉我如何使用AFNetworking 3.0或代码中的任何更改来处理任何类型的响应。

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.

推荐答案

尝试使用以下代码：

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

AFJSONRequestSerializer *serializer = [AFJSONRequestSerializer serializer];
[serializer setStringEncoding:NSUTF8StringEncoding];

manager.requestSerializer=serializer;
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
