使用 Parse 获取 Twitter 个人资料图片 - Android

Question

我一直在尝试获取 Twitter ParseUser 的个人资料图片。我使用 ParseTwitterUtils 允许用户登录我的应用程序，并尝试在注册我的解析数据库时获取他们的个人资料图片。

我使用了 Parse 文档中的以下内容：

ParseTwitterUtils.logIn(this, new LogInCallback() {
  @Override
  public void done(ParseUser user, ParseException err) {
    if (user == null) {
      Log.d("MyApp", "Uh oh. The user cancelled the Twitter login.");
    } else if (user.isNew()) {
      Log.d("MyApp", "User signed up and logged in through Twitter!"); 
          ParseTwitterUtils.getTwitter().getUserId();
		  user.setUsername(ParseTwitterUtils.getTwitter()
                .getScreenName());
              
		  user.saveInBackground();
		  makeTwitterRequest();
		  MyActivity();
    } else {
      Log.d("MyApp", "User logged in through Twitter!");
    }
  }
});

登录工作绝对正常，并且可以正常获取用户名。到目前为止，这是我尝试获取个人资料图片的 makeTwitterRequest() 方法。我还没有尝试将它存储到 Parse，只是使用 Twitter API 调用来获取它：

private void makeTwitterRequest() {
    	

    	Twitter twitter = ParseTwitterUtils.getTwitter();
    	String twitterUrl = "https://api.twitter.com/1.1/users/show.json?user_id=" + twitter.getUserId();
    	HttpClient client = new DefaultHttpClient();
    	HttpGet request = new HttpGet(twitterUrl);
    	twitter.signRequest(request);
		try {
			HttpResponse response = client.execute(request);
			
		} catch (ClientProtocolException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

运行此程序后，每当我点击 Twitter 登录按钮并登录时，在进行身份验证时，我都会收到错误消息：

我相信 Parse 应该通过登录过程自动解决这个问题，但是有人知道出了什么问题吗？非常感谢您的宝贵时间！

您可以使用以下sn-p代码：

Twitter twitter = ParseTwitterUtils.getTwitter();

HttpGet verifyGet = new HttpGet("https://api.twitter.com/1.1/users/show.json?user_id=" + twitter.getUserId());
ParseTwitterUtils.getTwitter().signRequest(verifyGet);

OkHttpClient client = new OkHttpClient();

Request request = null;

try {
    request = new Request.Builder()
            .url(verifyGet.getURI().toURL())
            .addHeader("Authorization", verifyGet.getFirstHeader("Authorization").getValue())
            .build();
} catch (MalformedURLException e) {
    e.printStackTrace();
}

client.newCall(request).enqueue(new Callback() {
    @Override
    public void onFailure(Request request, IOException e) {

    }

    @Override
    public void onResponse(Response response) throws IOException {
        if (response.isSuccessful()) {
            String jsonString = response.body().string();
        }
    }
});

这取决于 Square 的 OkHttp (https://github.com/square/okhttp)
