使用AFNetworking以文本和多張圖片上傳到谷歌Blob存儲

Question

僅供參考，這裏是我試圖在iOS中做/ Objective-C的

public static void saveTextsAndImagesOnServer(List<byte[]> images, long someID1, String servingUrl, boolean someFlag) 
      throws ClientProtocolException, IOException { 
     Log.d(TAG, "saveTextsAndImagesOnServer started "); 
     HttpClient httpClient = new DefaultHttpClient(); 
     HttpPost postRequest = new HttpPost(servingUrl); 
     MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE); 

     AdditionData extr = AdditionData.getInstance(); 
     reqEntity.addPart("red", new ByteArrayBody(("" + extr.getred()).getBytes(), "red")); 
     reqEntity.addPart("yellow", new ByteArrayBody(extr.getyellow.getBytes(), "yellow")); 
     reqEntity.addPart("green", new ByteArrayBody(extr.getgreen().getBytes(), "green")); 
     reqEntity.addPart("blue", new ByteArrayBody((extr.getblue()).getBytes(), "blue")); 
     reqEntity.addPart("someID1", new ByteArrayBody(("" + someID1).getBytes(), "someID1")); 
     if (someFlag) { 
      reqEntity.addPart("someFlag", new ByteArrayBody("true".getBytes(), "someFlag")); 
     } 
     int i = 0; 
     for (byte[] img : images) { 
      ByteArrayBody image = new ByteArrayBody(img, "img" + i++ + ".png"); 
      reqEntity.addPart("image", image); 
     } 
     postRequest.setEntity(reqEntity); 
     HttpResponse response = httpClient.execute(postRequest); 
     Log.d(TAG, "saveTextsAndImagesOnServer ended with response " + response.toString()); 
    } 

總結工作的Android/Java版本：基本上我我能夠將圖像和伴隨的元數據發送到blobstore。例如，元數據可幫助我識別發送圖像的人員。

現在試圖在iOS中做同樣的事情我寫了下面的代碼。但無論出於何種原因，元數據未保存在Blobstore中。我嘗試了一堆不同的東西，但我仍然沒有得到任何東西。我嘗試將我的元數據字符串更改爲base-64，但這不起作用。

的IOS代碼

-(void)postMultipartToServer 
{ 
    if (!self.destinationUrl) { 
     return; 
    } 

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; 
    NSLog(@"IS dictionary empty? %@", self.textDictionary); 

    [manager POST:self.destinationUrl 
     parameters:self.textDictionary 
    constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { 
     if ([self.imageDictionaries count]>0) 
      for (NSDictionary *imgDic in self.imageDictionaries) { 
       [formData appendPartWithFileData:UIImagePNGRepresentation([imgDic objectForKey:@"image"]) 
              name:[imgDic objectForKey:@"name"]//@"image" 
             fileName:[imgDic objectForKey:@"fileName"]//@"image.png" 
             mimeType:[imgDic objectForKey:@"mimeType"]//@"image/png" 
       ]; 
      } 


    } success:^(AFHTTPRequestOperation *operation, id responseObject) { 
     NSLog(@"Success: %@", responseObject); 
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
     NSLog(@"Error: %@", error); 
    }]; 
} 

這裏是字典

NSDictionary *textDictionary = @{ 
           @"yellow」:self. yellow, 
           @"red":self. red, 
           @"green」:self.green, 
           @「blue」:self. blue, 
           @「spouse」:self.spouse, 
           @"isFamouse」:@」true」};//you get the idea 

我在哪裏？

鑑於此設計適用於Android，我知道這可能是特別有可能的，因爲在涉及到語言時，http應該是不可知的。所以問題被簡化爲將字符串從iOS保存到Google blobstore。

我開始賞金，希望有人能幫我解決這個問題（也許是谷歌blobstore-iOS專家）。我也注意到其他人已經提出了相同的問題，但沒有回答。其他方面我也問過這樣一個問題：

更換方法如下FYI

-(void)postMultipartToServer 
{ 
    if (!self.destinationUrl) { 
     return; 
    } 

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; 

    [manager POST:self.destinationUrl 
     parameters:nil 
    constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { 

     if ([self.textDictionary count]>0){ 
      if ([self.textDictionary count]>0) 
       [self.textDictionary enumerateKeysAndObjectsUsingBlock:^(id key, id object, BOOL *stop) { 
        [formData appendPartWithFileData:[object dataUsingEncoding:NSUTF8StringEncoding] 
               name:key 
              fileName:key 
              mimeType:@"application/json" 
        ]; 

       }]; 
     } 

     if ([self.imageDictionaries count]>0) 
      for (NSDictionary *imgDic in self.imageDictionaries) { 
       [formData appendPartWithFileData:UIImagePNGRepresentation([imgDic objectForKey:@"image"]) 
              name:[imgDic objectForKey:@"name"]//@"image" 
             fileName:[imgDic objectForKey:@"fileName"]//@"image.png" 
             mimeType:[imgDic objectForKey:@"mimeType"]//@"image/png" 
       ]; 
      } 
    } success:^(AFHTTPRequestOperation *operation, id responseObject) { 
     NSLog(@"Success: %@", responseObject); 
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
     NSLog(@"Error: %@", error); 
    }]; 
}

最終HTTP請求將是一個字符串。您可以記錄該字符串。可能想爲此使用一個小圖像。然後對android請求做同樣的事情，看看有什麼不同。
