iOS Upload Image and Text using HTTP POST

Merci d'avoir lu.

je suis nouveau sur iOS, et je suis en train de télécharger une Image et un texte à l'aide de multi-part form encoding dans iOS.

l'équivalent curl est quelque chose comme ceci: curl -F "param1=value1" -F "param2=@testimage.jpg" "http://some.ip.address:5000/upload"

la commande curl ci-dessus renvoie la réponse correcte attendue dans JSON.

problème: Je continue à recevoir une requête HTTP 400 ce qui signifie que je fais quelque chose de mal lors de la composition du corps du POST HTTP.

Ce Que J'Ai Fait: Pour référence, j'ai essayé le API de Flickr pour iOS "POST taille trop grand!" et Objectif C: Comment télécharger des images et du texte à l'aide de HTTP POST? . Mais, je continue à avoir un HTTP 400.

j'ai essayé le ASIHttpRequest mais il y avait un autre problème (le rappel n'a jamais été appelé). Mais je n'ai pas enquêté sur ça depuis J'ai entendu dire que le développeur a cessé de supporter la bibliothèque: http://allseeing-i.com / [request_release] ;

Quelqu'un pourrait-il m'aider?

voici le code de mon application pour afficher une image sur notre serveur web:

// Dictionary that holds post parameters. You can set your post parameters that your server accepts or programmed to accept.
NSMutableDictionary* _params = [[NSMutableDictionary alloc] init];
[_params setObject:[NSString stringWithString:@"1.0"] forKey:[NSString stringWithString:@"ver"]];
[_params setObject:[NSString stringWithString:@"en"] forKey:[NSString stringWithString:@"lan"]];
[_params setObject:[NSString stringWithFormat:@"%d", userId] forKey:[NSString stringWithString:@"userId"]];
[_params setObject:[NSString stringWithFormat:@"%@",title] forKey:[NSString stringWithString:@"title"]];

// the boundary string : a random string, that will not repeat in post data, to separate post data fields.
NSString *BoundaryConstant = [NSString stringWithString:@"----------V2ymHFg03ehbqgZCaKO6jy"];

// string constant for the post parameter 'file'. My server uses this name: `file`. Your's may differ 
NSString* FileParamConstant = [NSString stringWithString:@"file"];

// the server url to which the image (or the media) is uploaded. Use your server url here
NSURL* requestURL = [NSURL URLWithString:@""]; 

// create request
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];                                    
[request setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
[request setHTTPShouldHandleCookies:NO];
[request setTimeoutInterval:30];
[request setHTTPMethod:@"POST"];

// set Content-Type in HTTP header
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", BoundaryConstant];
[request setValue:contentType forHTTPHeaderField: @"Content-Type"];

// post body
NSMutableData *body = [NSMutableData data];

// add params (all params are strings)
for (NSString *param in _params) {
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", BoundaryConstant] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"\r\n\r\n", param] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"%@\r\n", [_params objectForKey:param]] dataUsingEncoding:NSUTF8StringEncoding]];
}

// add image data
NSData *imageData = UIImageJPEGRepresentation(imageToPost, 1.0);
if (imageData) {
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", BoundaryConstant] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"; filename=\"image.jpg\"\r\n", FileParamConstant] dataUsingEncoding:NSUTF8StringEncoding]];

XJones " la réponse a fonctionné comme un charme.

mais il n'a pas mentionné/déclaré Les variables _params , BoundaryConstant et requestURL . Donc, j'ai pensé à poster cette partie comme un ajout à son poste, afin qu'il puisse aider d'autres à l'avenir.

// Dictionary that holds post parameters. You can set your post parameters that your server accepts or programmed to accept.
NSMutableDictionary* _params = [[NSMutableDictionary alloc] init];
[_params setObject:[NSString stringWithString:@"1.0"] forKey:[NSString stringWithString:@"ver"]];
[_params setObject:[NSString stringWithString:@"en"] forKey:[NSString stringWithString:@"lan"]];
[_params setObject:[NSString stringWithFormat:@"%d", userId] forKey:[NSString stringWithString:@"userId"]];
[_params setObject:[NSString stringWithFormat:@"%@",title] forKey:[NSString stringWithString:@"title"]];

// the boundary string : a random string, that will not repeat in post data, to separate post data fields.
NSString *BoundaryConstant = [NSString stringWithString:@"----------V2ymHFg03ehbqgZCaKO6jy"];

// string constant for the post parameter 'file'. My server uses this name: `file`. Your's may differ 
NSString* FileParamConstant = [NSString stringWithString:@"file"];

// the server url to which the image (or the media) is uploaded. Use your server url here
NSURL* requestURL = [NSURL URLWithString:@""]; 

comme j'ai mentionné earler, ce n'est pas une réponse en soi, juste un addon à XJones' post.

[request setHTTPMethod:@"POST"];
[WebRequestProcessor process:request];

utiliser le délégué pour notifier l'état d'avancement du téléchargement.

utiliser le notificationName pour la notification lorsque la demande est terminée.

utilisez la file pour ajouter cette demande dans votre file d'attente d'opération afin qu'elle soit traitées en temps et en heure.

voici le code swift actif traduit à partir du code fourni par @xjones. Merci beaucoup pour votre aide contrainte. La vôtre était la seule façon qui a fonctionné pour moi. J'ai utilisé cette méthode pour envoyer 1 image et un autre paramètre à un service Web asp.net

Voici une version Swift. Notez que si vous ne voulez pas envoyer des données de formulaire, il est toujours important d'envoyer le formulaire vide limite. Flask en particulier s'attend à des données de forme suivies de données de fichier et ne remplira pas request.files sans la première limite.

  let composedData = NSMutableData()

  // Set content type header
  let BoundaryConstant = "--------------------------3d74a90a3bfb8696"
  let contentType = "multipart/form-data; boundary=\(BoundaryConstant)"
  request.setValue(contentType, forHTTPHeaderField: "Content-Type")

  // Empty form boundary
  composedData.appendData("--\(BoundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

  // Build multipart form to send image
  composedData.appendData("--\(BoundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
  composedData.appendData("Content-Disposition: form-data; name=\"file\"; filename=\"image.jpg\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
  composedData.appendData("Content-Type: image/jpeg\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
  composedData.appendData(rawData!)
  composedData.appendData("\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
  composedData.appendData("--\(BoundaryConstant)--\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

  request.HTTPBody = composedData

  // Get content length
  let length = "\(composedData.length)"
  request.setValue(length, forHTTPHeaderField: "Content-Length")

Note: toujours utiliser sendAsynchronousRequest méthode au lieu de sendSynchronousRequest pour télécharger/télécharger des données pour éviter de bloquer le thread principal. Ici, j'ai utilisé sendSynchronousRequest à des fins de test seulement.
