Question

我正在尝试使用以下代码将图像上传到Twitter，但我收到了一个限制错误：

ConfigurationBuilder builder = new ConfigurationBuilder();
builder.setOAuthConsumerKey(TwitterConst.CONSUMER_KEY);
builder.setOAuthConsumerSecret(TwitterConst.CONSUMER_SECRET);

String access_token = mSharedPreferences.getString(TwitterConst.PREF_KEY_TOKEN, "");
String access_token_secret = mSharedPreferences.getString(TwitterConst.PREF_KEY_SECRET, "");

AccessToken accessToken = new AccessToken(access_token, access_token_secret);
Twitter twitter = new TwitterFactory(builder.build()).getInstance(accessToken);

StatusUpdate status = new StatusUpdate("Sample message: " + args[0] + " - Download it from Google Play at goo.gl/xxxxxx");
if (foto_to_share.equals("https://www.mywebsite.com/Folder/default/fb_stub.png")) {
    status.setMedia(String_to_File("https://www.mywebsite.com/Folder/default/fb_stub.png"));
} else {
    status.setMedia(String_to_File("http://www.mywebsite.com/Folder/upload/" + session_userid + "/" + foto_to_share));
 }
 twitter4j.Status response = twitter.updateStatus(status);

第一张图片是139 KB，第二张图片是140 KB大。这两个图像都在网络上，String_to_File方法将它们下载到SD卡。

我确信我没有达到我知道的任何限制，因为我无法发布图像，但我可以发送一条消息。但是，我认为这个String_to_File方法存在一些问题，因为它将第一个（存根）图像保存到SD卡，但是当它保存第二个时，它已经坏了或因为我无法打开它。

public File String_to_File(String img_url) {

            try {
                File rootSdDirectory = Environment.getExternalStorageDirectory();

               casted_image = new File(rootSdDirectory, "attachment.jpg");
                if (casted_image.exists()) {
                casted_image.delete();
                }
                casted_image.createNewFile();

                FileOutputStream fos = new FileOutputStream(casted_image);

                URL url = new URL(img_url);
                HttpURLConnection connection = (HttpURLConnection) url
                    .openConnection();
                connection.setRequestMethod("GET");
                connection.setDoOutput(true);
                connection.connect();
                InputStream in = connection.getInputStream();

                byte[] buffer = new byte[1024];
                int size = 0;
                while ((size = in.read(buffer)) > 0) {
                fos.write(buffer, 0, size);
                }
                fos.close();
                return casted_image;

            } catch (Exception e) {

                System.out.print(e);
                // e.printStackTrace();

            }
            return casted_image;
}

有什么想法吗？

Answer 1

我发现了问题并且与Twitter无关，因此应删除此主题。

问题是上传到我服务器的图像名称中的特殊字符已被删除，因此存在不匹配。这就是为什么String_to_File（）无法下载图像，因为它正在寻找my_image.png，但它找到的只是myimage.png。

Answer 2

如果您认为库中没有错误，那么您可能没有为请求使用安全连接。请参阅此处的Twitter文档：

https://dev.twitter.com/overview/api/ssl

由于更新限制错误，无法将图片发布到Twitter
