AFNetworking和POST請求

Question

我在從AFNetworking發出POST請求時收到error.userInfo中的此響應。 任何人都可以告訴我失去了什麼明顯的東西或需要修復我的服務器端？

Request Failed with Error: Error Domain=AFNetworkingErrorDomain Code=-1016 "Expected content type {( "text/json", "application/json", "text/javascript")}, got text/html" UserInfo=0x6d7a730 {NSLocalizedRecoverySuggestion=index test, AFNetworkingOperationFailingURLResponseErrorKey=, NSErrorFailingURLKey=http://54.245.14.201/, NSLocalizedDescription=Expected content type {( "text/json", "application/json", "text/javascript")}, got text/html, AFNetworkingOperationFailingURLRequestErrorKey=http://54.245.14.201/>}, { AFNetworkingOperationFailingURLRequestErrorKey = "http://54.245.14.201/>"; AFNetworkingOperationFailingURLResponseErrorKey = ""; NSErrorFailingURLKey = "http://54.245.14.201/"; NSLocalizedDescription = "Expected content type {(\n \"text/json\",\n \"application/json\",\n
\"text/javascript\"\n)}, got text/html"; NSLocalizedRecoverySuggestion = "index test"; }

而我正在使用這段代碼;

AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url]; 
[httpClient registerHTTPOperationClass:[AFJSONRequestOperation class]]; 
[httpClient setDefaultHeader:@"Accept" value:@"application/json"]; 
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys: 
         @"Ans", @"name", 
         @"29", @"age", 
         nil]; 

NSMutableURLRequest *request = [httpClient requestWithMethod:@"POST" path:@"/" parameters:params]; 

AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request 
    success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) { 
     NSLog(@"Success"); 
     NSLog(@"%@",JSON); 

    } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) { 
     NSLog(@"Request Failed with Error: %@, %@", error, error.userInfo); 
     NSLog(@"Failure"); 
}]; 

[operation start]; 
[operation waitUntilFinished]; 

Answer 1

默認情況下，AFJSONRequestOperation只接受「文字/ JSON」 ，「application/json」或者「text/javascript」內容類型，但是你會得到「text/html」。

固定在服務器上會更好，但你也可以添加「text/html的」內容鍵入您的應用程序可以接受的：

[AFJSONRequestOperation addAcceptableContentTypes:[NSSet setWithObject:@"text/html"]]; 

它的工作對我來說，希望這有助於！

你發送的AFHTTPClient這個POST請求？如果是這樣，你需要設置操作類是：

AFHTTPClient * client = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:@"http://localhost:8080"]]; 
// ... 
[client registerHTTPOperationClass:[AFJSONRequestOperation class]]; 
[client setDefaultHeader:@"Accept" value:@"application/json"]; 
// ... 

// EDIT: Use AFHTTPClient's POST method 
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys: 
         @"Ans", @"name", 
         @"29", @"age", nil]; 

// POST, and for GET request, you need to use |-getPath:parameters:success:failure:| 
[client postPath:@"/" 
     parameters:params 
     success:^(AFHTTPRequestOperation *operation, id responseObject) { 
      NSLog(@"RESPONSE: %@", responseObject); 
      // ... 
     } 
     failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
      if (error) 
      NSLog(@"%@", [error localizedDescription]); 
      // ... 
     }

設置你的價值在這個代碼，並檢查它是否適合你

AFHTTPClient *httpClient = [[AFHTTPClient alloc]initWithBaseURL:[NSURL URLWithString:kBASEURL]]; 
     NSString *_path = [NSString stringWithFormat:@"groups/"]; 
     _path = [_path stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; 
     NSLog(@"%s %@",__PRETTY_FUNCTION__,_path); 
     NSMutableURLRequest *request = [httpClient requestWithMethod:@"POST" 
                   path:_path 
                  parameters:postParams]; 
     [httpClient release]; 

     AFJSONRequestOperation *operation = [AFJSONRequestOperation 
              JSONRequestOperationWithRequest:request 
              success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) { 
               if ([JSON isKindOfClass:[NSArray class]] || [JSON isKindOfClass:[NSDictionary class]]) { 
                completed(JSON); 
               } 
               else { 
               } 
               [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO];            

              } 
              failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) { 
               NSLog(@" response %@ \n error %@ \n JSON %@",response,error,JSON); 
               [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO];           
               errored(error); 
              }]; 

     NSOperationQueue *queue = [[[NSOperationQueue alloc] init] autorelease]; 
     [queue addOperation:operation]; 
     [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES];
