ASIFormDataRequest in AFNetworking?

Question

Ich habe einen Code in ASIHTTP, aber ich möchte auf AFNetworking weitergehen. ich ASIFormDataRequest für einige POST-Anfragen verwendet und dieser Code funktioniert:

NSURL *url = [NSURL URLWithString:@"http://someapiurl"]; 
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url]; 
[request setPostValue:@"123" forKey:@"phone_number"]; 
[request startSynchronous]; 
NSError *error = [request error]; 
if (!error) { 
    NSLog(@"Response: %@", [[request responseString] objectFromJSONString]); 

} 

aber, als ich versuchte, das gleiche mit AFNetworking zu tun, ich in Problem mit Content-Type bekam (ich glaube).

Dieser Code wird AFNetworking, und es funktioniert nicht:

NSURL *url = [NSURL URLWithString:@"http://dev.url"]; 
    AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url]; 

    NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys: 
          @"123", @"phone_number", 
          nil]; 
    NSMutableURLRequest *request = [httpClient requestWithMethod:@"POST" path:@"/api/get_archive" parameters:params]; 
    [request setValue:@"application/x-www-form-urlencoded; charset=UTF8" forHTTPHeaderField:@"Content-Type"]; 

    AFHTTPRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest 
*request, NSHTTPURLResponse *response, id JSON) { 
       NSLog(@"Response: %@", JSON); 
      } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON){ 
       NSLog(@"Error: %@", error); 
      }]; 
      [operation start]; 

URL in Ordnung ist, wird diese geprüft. Ich bin vom Server immer dieses:

{NSErrorFailingURLKey=http://dev.thisapiurl, NSLocalizedDescription=Expected content type {(
    "text/json", 
    "application/json", 
    "text/javascript" 
)}, got text/html} 

Answer 1

Das Problem, das Sie haben, ist, weil Sie ein Instanziieren AFJSONRequestOperation, die standardmäßig einen JSON-freundlichen Antworttyp erwartet. Erwarten Sie eine JSON-Antwort? Wenn nicht, sollten Sie eine weniger spezifische Request-Klasse verwenden. Zum Beispiel könnten Sie HTTPRequestOperationWithRequest:.

NSURL *url = [NSURL URLWithString:@"http://dev.url"]; 
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url]; 

NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys: 
         @"123", @"phone_number", 
         nil]; 
NSMutableURLRequest *request = [httpClient requestWithMethod:@"POST" path:@"/api/get_archive" parameters:params]; 
[request setValue:@"application/x-www-form-urlencoded; charset=UTF8" forHTTPHeaderField:@"Content-Type"]; 

//Notice the different method here! 
AFHTTPRequestOperation *operation = [httpClient HTTPRequestOperationWithRequest:request 
    success:^(AFHTTPRequestOperation *operation, id responseObject) { 
      NSLog(@"Response: %@", responseObject); 
     } 
    failure:^(AFHTTPRequestOperation *operation, NSError *error){ 
      NSLog(@"Error: %@", error); 
     }]; 
//Enqueue it instead of just starting it. 
[httpClient enqueueHTTPRequestOperation:operation]; 

Wenn Sie spezifischere Request/Response-Typen (JSON, XML, etc.) haben, können Sie diese spezifischen AFHTTPRequestOperation Subklassen verwenden. Ansonsten benutze einfach den Vanilla HTTP one.

ich durch die gleiche Sache wie Sie in letzter Zeit ging. Hier ist eine benutzerdefinierte Klasse, die ich geschrieben habe, um so ziemlich jede Netzwerkanfrage zu bearbeiten.

Dies fügt in ein paar Funktionen, die Sie möglicherweise nicht brauchen oder wollen, fühlen Sie sich frei, es zu ändern, wie Sie so lange brauchen Der Abschnitt "Copyright" bleibt bestehen. Ich benutze das APIKey, um die Anfrage zu validieren kam von meiner App und nicht jemand versucht, Dinge zu hacken.

es Calling (vorausgesetzt, Sie NetworkClient.h aufgenommen haben:

NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys: 
          @"ParamValue1", @"ParamName1", 
          @"ParamValue2", @"ParamName2", 
          nil]; 


    [NetworkClient processURLRequestWithURL:nil andParams:params block:^(id obj) { 
     if ([obj isKindOfClass:[NSArray class]]) { 
      // Do whatever you want with the object. In this case, I knew I was expecting an Array, but it will return a Dictionary if that is what the web-service responds with. 
     } 
    }];  

können auch:

NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys: 
          @"ParamValue1", @"ParamName1", 
          nil]; 

    NSString *urlString = @"https://SuppliedURLOverridesDefault"; 
    [NetworkClient processURLRequestWithURL:urlString 
            andParams:params 
           syncRequest:YES 
         alertUserOnFailure:NO 
             block:^(id obj) { 
              if ([obj isKindOfClass:[NSArray class]]) { 
               // Do stuff 
              } 
             }]; 

in einer beliebigen Anzahl von Parametern So nehmen Sie es, injizieren einen apikey oder irgendetwas anderes, wenn Sie wollen und zurück entweder ein Dictionary oder ein Array je nach Web-Service.Dies erwartet SBJson BTW.
