FourSquare那種照片上載了Android

Question

我需要上傳的照片上使用FourSquare.If人已經做到了籤籤，請幫我在路過parameters.I都提到FourSquare那種官方文件： https://developer.foursquare.com/docs/photos/add。我在最後三個參數中遇到問題。 請幫助我，如果你要提前做it.Thank你......

Answer 1

參數postUrl，postContentId和postText是可選的，所以你不必爲他們提供。 postUrl和postContentId用於提供您的照片可以鏈接到的鏈接以獲取更多信息。 postText是對照片的簡短評論。

Answer 3

我成功上傳的圖像通過下面的代碼來四方的

mBitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream); 
byte[] bitmapdata = stream.toByteArray(); 

HttpClient httpclient = new DefaultHttpClient(); 
HttpPost httppost = new HttpPost("https://api.foursquare.com/v2/photos/add"); 

try 
{ 
    MultipartEntity entity = new MultipartEntity(); 
    entity.addPart("v", new StringBody("20121210")); 
    entity.addPart("venueId", new StringBody(venue.getId())); 
    entity.addPart("public", new StringBody("1")); 
    entity.addPart("oauth_token", new  StringBody(mAccessToken)); 
    ByteArrayBody imgBody = new ByteArrayBody(bitmapdata, "image/jpeg", "FS_image"); 

    entity.addPart("image",imgBody); 
    httppost.setEntity(entity); 
    HttpResponse response = httpclient.execute(httppost); 
    Log.v("response","" +response); 
    responseResult = inputStreamToString(response.getEntity().getContent()).toString(); 
} 
catch (ClientProtocolException e) 
{ 
    Log.d(TAG, "Opening URL " +e); 
}
