AFNetworking版本3内容类型错误

Question

我正在制作一个iphone应用程序，它将与特定的ASP.NET服务器交互。我有下面的代码注册：

- (void)post:(NSString *)path parameters:(NSDictionary *)parameters success:(void (^)(id))success failure:(void (^)(NSError *))failure { 
    path = [path stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; 
    NSLog(@"path: %@, %@", path, parameters); 
    manager.responseSerializer = [AFJSONResponseSerializer serializer]; 
    manager.requestSerializer = [AFJSONRequestSerializer serializer]; 
    [manager.requestSerializer setValue:@"parse-application-id-removed" forHTTPHeaderField:@"X-Parse-Application-Id"]; 
    [manager.requestSerializer setValue:@"parse-rest-api-key-removed" forHTTPHeaderField:@"X-Parse-REST-API-Key"]; 
    [manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; 
    manager.securityPolicy.allowInvalidCertificates = YES; 

    [manager POST:path parameters:parameters progress:nil success:^(NSURLSessionTask *task, id responseObject) { 
     NSLog(@"JSON: %@", responseObject); 
     [myDelegate StopIndicator]; 
     success(responseObject); 
    } failure:^(NSURLSessionTask *operation, NSError *error) { 
     NSLog(@"Error: %@", error); 
     [myDelegate StopIndicator]; 
     failure(error); 
       UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Alert" message:error.localizedDescription delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil]; 
       [alert show]; 
    }]; 

} 




//Register 

-(void)registerUser:(NSString *)usertype firstname:(NSString *)firstname middlename:(NSString *)middlename lastname:(NSString *)lastname registration:(NSString *)registration password:(NSString *)password confirmpass:(NSString *)confirmpass email:(NSString *)email mobile:(NSString *)mobile success:(void (^)(id))success failure:(void (^)(NSError *))failure 
    { 
     NSDictionary *requestDict = @{@"UserTypeId" : usertype, @"FirstName" : firstname, @"MiddleName" : middlename,@"LastName" : lastname, @"RegNumber" : registration ,@"Password": password,@"ConfirmPassword" : confirmpass, @"EmailAddress" : email, @"MobileNumber" : mobile}; 

     [self post:kUrlSignup parameters:requestDict success:^(id responseObject) { 

      NSLog(@"registerWithEmail: %@", responseObject); 
      responseObject=(NSMutableDictionary *)[NullValueChecker checkDictionaryForNullValue:[responseObject mutableCopy]]; 
      if([self isStatusOK:responseObject]) 
      { 
       success(responseObject); 
      } else 
      { 
       [myDelegate StopIndicator]; 
       failure(nil); 
      } 
     } failure:^(NSError *error) 
     { 
      [myDelegate StopIndicator]; 

      failure(error); 
     }]; 

    } 

但它让我有与内容类型做了以下错误：

Error: Error Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: unsupported media type (415)" UserInfo={com.alamofire.serialization.response.error.response=<NSHTTPURLResponse: 0x7c14e5c0> { URL: http://192.168.0.129/IISService/Service.svc/Registration } { status code: 415, headers { 
    "Cache-Control" = private; 
    "Content-Length" = 0; 
    Date = "Mon, 01 Aug 2016 05:38:44 GMT"; 
    Server = "Microsoft-IIS/8.5"; 
    "X-AspNet-Version" = "4.0.30319"; 
    "X-Powered-By" = "ASP.NET"; 
} }, NSErrorFailingURLKey=http://192.168.0.129/IISService/Service.svc/Registration, NSLocalizedDescription=Request failed: unsupported media type (415), com.alamofire.serialization.response.error.data=<>} 

我不知道如果这个错误是从服务器端或者我犯了一些错误。我该如何解决这个错误？

Answer 1

默认情况下，AFHTTPResponseSerializer支持处理的请求，其Content-Type等于的application/json，text/json，text/javascript要么响应。如果您的服务器返回Content-Type等于text/html或其他的响应，则AFHTTPResponseSerializer将不会处理您的响应并引发错误。您可以都由你自己如下添加接受类型：

AFJSONResponseSerializer *serializer = [AFJSONResponseSerializer serializer]; 
NSMutableSet *acceptTypes = [NSMutableSet setWithSet:serializer.acceptableContentTypes]; 
[acceptTypes addObject:@"your-content-type"]; 
serializer.acceptableContentTypes = acceptTypes; 
manager.responseSerializer = serializer; 

Answer 2

AFHTTPSessionManager *manager = [AFHTTPRequestOperationManager manager]; 
manager.requestSerializer = [AFJSONRequestSerializer serializer]; 
NSDictionary *parameters = @{@"username":username, @"password":password}; 
[manager POST:@"URL Here" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) { 
    NSLog(@"JSON: %@", responseObject); 
} failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
    NSLog(@"Error: %@", error); 
}]; 

这确实请求的创作，根据requestSerializer设置设置它的内容类型，并编码JSON你。

更新1： -

+(void)callWebServicePOST_withAPIName:(NSString *)url withParameters:(id)parameters withBlock:(ResponseCompilationBlock)_Block { 
    [[AFHTTPRequestSerializer serializer] setTimeoutInterval:60]; 
    [[AFHTTPSessionManager manager].requestSerializer setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData]; 

    [[AFHTTPSessionManager manager] POST:url parameters:parameters progress:^(NSProgress * _Nonnull uploadProgress) { 

    } success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) { 
     NSLog (@"response:%@", responseObject); 
     _Block (YES, 200, responseObject); 
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { 
     NSLog(@"error:%@", error); 
     _Block (NO, 400, error); 
    }]; 
} 

声明中的AppDelegate文件这种方法，并调用它，就像这样： -

[Appdelegate callWebServicePOST_withAPIName:@"url string" withParameters:params withBlock:^(BOOL isSuccess, NSInteger statusCode, id response) { 
    if (isSuccess) { 
     /* Do further procedure here */ 
    } 
    else { 
     NSLog (@"%@", [error localizedDescription]) 
    } 
}
