我也试过这样做

-(void)postdata
{
    NSError *error;

    NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
    NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];
    NSURL *url = [NSURL URLWithString:@"http://virtuzo.in/AhprepaidTestService/AhprepaidAPI_Json.svc/ValidateLoginService"];
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
                                                           cachePolicy:NSURLRequestUseProtocolCachePolicy
                                                       timeoutInterval:60.0];

    [request addValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [request addValue:@"application/json" forHTTPHeaderField:@"Accept"];

    [request setHTTPMethod:@"POST"];
    NSDictionary *mapData = [[NSDictionary alloc] initWithObjectsAndKeys: @"admin", @"UserName",
                             @"1234", @"Pwd",
                             nil];
    NSData *postData = [NSJSONSerialization dataWithJSONObject:mapData options:0 error:&error];
    [request setHTTPBody:postData];


    NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request    completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {

        NSLog(@"reponse==%@",response);
        NSLog(@"error==%@",error);


    }];

    [postDataTask resume];

}

我仍然会遇到同样的错误

原因是您得到的web服务响应实际上不是JSON响应。检查您得到的响应，这将有助于您的代码工作

尝试不同的响应序列化程序。答复的格式是什么？它是字符串还是json格式的？根据该设置响应序列化程序。您可以在不同的工具中检查您的响应，如AdvanceRESTClient、postman，或者您可以询问api或web服务的开发者

更新：

Update :

NSError *error;

 NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
  NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];
  NSURL *url = [NSURL URLWithString:@"[JSON SERVER"];
  NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
                                                  cachePolicy:NSURLRequestUseProtocolCachePolicy
                                           timeoutInterval:60.0];

 [request addValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
 [request addValue:@"application/json" forHTTPHeaderField:@"Accept"];

 [request setHTTPMethod:@"POST"];
 NSDictionary *mapData = [[NSDictionary alloc] initWithObjectsAndKeys: @"TEST   IOS", @"name",
             @"IOS TYPE", @"typemap",
             nil];
 NSData *postData = [NSJSONSerialization dataWithJSONObject:mapData options:0 error:&error];
 [request setHTTPBody:postData];


  NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request    completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {

  }];

  [postDataTask resume];

试试这样的。这是没有网络的本地方式。您将在完成处理程序中设置数据作为响应。如果您的响应是字符串，则将该数据转换为字符串。如果响应是json格式的，则在完成处理程序块中以json格式转换该数据。转换示例

 //data to string
  NSString *myString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

 /data to json object
 NSArray *jsonArray = [NSJSONSerialization JSONObjectWithData:myNSData options:kNilOptions error:&error]; // here two posibilitiew NSArray or NSDictionary (Try both ot you can use id)

希望这能解决您的问题：）

更新2:

NSString *urlString2 = @"http://virtuzo.in/AhprepaidTestService/AhprepaidAPI_Json.svc/ValidateLoginService?UserName=admin&Pwd=1234";



NSURL *myUrl = [NSURL URLWithString:urlString2];





NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:myUrl];
[request setHTTPMethod:@"POST"];


 NSURLSession *session = [NSURLSession sharedSession];


[[session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {


    NSString *str = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
    NSLog(@"str is %@",str);




}]resume];

这和邮递员的回答是一样的。我已经试过了。我刚刚用url附加了参数

更新3:

NSString *urlString2 = @"http://virtuzo.in/AhprepaidTestService/AhprepaidAPI_Json.svc/ValidateLoginService?UserName=admin&Pwd=1234";



NSURL *myUrl = [NSURL URLWithString:urlString2];





NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:myUrl];
[request setHTTPMethod:@"POST"];


 NSURLSession *session = [NSURLSession sharedSession];


[[session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {


    NSString *str = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
    NSLog(@"str is %@",str);




}]resume];

您得到的是xml字符串，因此，序列化几乎没有完成

1）下载。在你的项目中进行除鼠和投放。（当你构建时，你会在这个类中得到错误。每当你在这个类中得到错误注释（//）这一行。这是因为它没有使用ARC）

更新代码：

 NSString *urlString2 = @"http://virtuzo.in/AhprepaidTestService/AhprepaidAPI_Json.svc/ValidateLoginService?UserName=admin&Pwd=1234";



NSURL *myUrl = [NSURL URLWithString:urlString2];





NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:myUrl];
[request setHTTPMethod:@"POST"];


 NSURLSession *session = [NSURLSession sharedSession];


[[session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {


    NSString *str = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
    NSLog(@"str is %@",str);




    NSError *parseError = nil;
    NSDictionary *xmlDictionary = [XMLReader dictionaryForXMLString:str error:&parseError];
    NSLog(@" %@", xmlDictionary);

    NSString *myfinalString = [[xmlDictionary valueForKey:@"string"]valueForKey:@"text"];
    NSLog(@"string is %@",myfinalString);



    NSError *jsonError;
    NSData *objectData = [myfinalString dataUsingEncoding:NSUTF8StringEncoding];
    NSDictionary *json = [NSJSONSerialization JSONObjectWithData:objectData
                                                         options:NSJSONReadingMutableContainers
                                                           error:&jsonError];
    NSLog(@"json is : %@",json);

}]resume];

我在错误块中出错。如何检查响应RRY dude，我错误地更新了你的答案而不是我的：（嘿，我已经更新了我的答案。检查一下。希望这会有所帮助。我已经使用了u所说的，并发布了带有参数和url的代码。仍然得到相同的错误您在完成处理程序中的数据中得到了什么？您的数据为零吗？按数据检查数据的长度。长度。第二件事完成处理程序中的错误描述是什么？您可以按错误进行检查。localizedDescription。您要发送什么参数以及如何发送？告诉我AlsonDictionary*mapData=[[NSDictionary alloc]initWithObjectsAndKeys:@“admin”@“UserName”@“1234”@“Pwd”，nil]；这是我要发送的参数，我的问题中有完整的代码
