多文件上传问题 - ios 中的音乐和图像

Question

在我的应用程序中，我必须将图像文件和音频文件上传到服务器。当我同时上传这两个文件时，它们上传成功但音频文件未作为音频接收，而是在服务器上作为 text/plain 文件类型接收。下面是发送文件的代码

    //For Audio Get
 (IBAction)audioCLICK:(id)sender
{
    MPMediaPickerController *mediaPicker = [[MPMediaPickerController alloc] initWithMediaTypes: MPMediaTypeAny];

    mediaPicker.delegate = self;
    mediaPicker.allowsPickingMultipleItems = YES;
    mediaPicker.prompt = @"Select songs for play";

    [self presentModalViewController:mediaPicker animated:YES];

}

- (void) mediaPicker: (MPMediaPickerController *) mediaPicker didPickMediaItems: (MPMediaItemCollection *) mediaItemCollection
{

    MPMediaItem *items = [[mediaItemCollection items] objectAtIndex:0];
    NSURL *url = [items valueForProperty:MPMediaItemPropertyAssetURL];
    NSString *songTitle = [items valueForProperty:MPMediaItemPropertyTitle];
    txt_audio.text=songTitle;
    [mediaPicker dismissViewControllerAnimated:YES completion:nil];
}

//For  Get Image

- (IBAction)imageCLICK:(id)sender
{
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.allowsEditing = YES;
    picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

    [self presentViewController:picker animated:YES completion:NULL];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    UIImage *chosenImage = info[UIImagePickerControllerEditedImage];

   UIImage *image_post = chosenImage;

    imageURL = [info valueForKey:UIImagePickerControllerReferenceURL];
    NSLog(@"image URL:%@",imageURL);

    dataImage = [[NSData alloc] init];
    dataImage = UIImageJPEGRepresentation(image_post,0.7);

    NSURL *imageURL = [info valueForKey:UIImagePickerControllerReferenceURL];
    NSLog(@"image URL:%@",imageURL);
    ALAssetsLibraryAssetForURLResultBlock resultblock = ^(ALAsset *myasset)
    {
        ALAssetRepresentation *representation = [myasset defaultRepresentation];
        NSString *fileName = [representation filename];
        NSLog(@"fileName : %@",fileName);
        txt_image.text = fileName;
    };

    ALAssetsLibrary* assetslibrary = [[ALAssetsLibrary alloc] init];
    [assetslibrary assetForURL:imageURL
                   resultBlock:resultblock
                  failureBlock:nil];


    [self dismissModalViewControllerAnimated: YES];
}

//For Upload file in Server

-(void)UploadData
{
    NSDictionary *dict = @{
                           @"pausetaskname" : txt_name.text,
                           };
    //for Audio

    NSString *urlString = @"file://localhost/Users/UserName/Documents/filename.txt";
    NSURL *url = [NSURL URLWithString:urlString];
    NSString *path = [audioURL path];
    NSLog(@"%@", path);

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents directory
    NSString *pathaudio = [audioURL path];
    NSString *filePath = [documentsDirectory stringByAppendingPathComponent:pathaudio];
    NSLog(@"AudioPath:%@",filePath);
    NSData* audioData = [filePath dataUsingEncoding:NSUTF8StringEncoding];

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

    manager.requestSerializer=[AFJSONRequestSerializer serializer];

    manager.responseSerializer.acceptableContentTypes=[NSSet setWithObject:@"text/html"];


    [manager POST:[NSString stringWithFormat:@"http://mxicoders.in/projects/mip/ws/Webservice/add_task_demo"] parameters:dict constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
     {
                 [formData appendPartWithFileData:dataImage name:@"pausetaskimage" fileName:@"photo.jpg" mimeType:@"image/jpeg"];

         [formData appendPartWithFileData:audioData name:@"pausetaskaudio" fileName:[NSString stringWithFormat:@"%@.m4a",@"sOng"] mimeType:@"audio/m4a"];


     }
          success:^(AFHTTPRequestOperation *operation, id responseObject)
     {

         NSLog(@"Sucess");
         NSLog(@"%@",responseObject);



     }
          failure:^(AFHTTPRequestOperation *operation, NSError *error)
     {


         NSLog(@"%@",error);


     }];    
}

上传文件后我得到以下回复：- 收到音频文件 text/plain 请参阅 audio_data > file_type 响应

Answer 1

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

    manager.requestSerializer=[AFJSONRequestSerializer serializer];

    manager.responseSerializer.acceptableContentTypes=[NSSet setWithObject:@"text/html"];

    [manager POST:[NSString stringWithFormat:@"http://mxicoders.in/projects/mip/ws/Webservice/upload_audio"] parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
     {
         [formData appendPartWithFileData:Data name:@"pausetaskaudio" fileName:[NSString stringWithFormat:@"%@.m4a",@"sOng"] mimeType:@"audio/m4a"];
}
          success:^(AFHTTPRequestOperation *operation, id responseObject)
     {
         NSLog(@"Sucess");
         NSLog(@"%@",responseObject);
}
}

回复：-

{
    info = "text/plain";
    upload =     {
        pausetaskaudio =         {
            error = 0;
            name = "song.m4a";
            size = 80;
            "tmp_name" = "/tmp/phpTjJZaA";
            type = "audio/m4a";
        };
    };
}
