Java 无法让HttpClient执行Imgur API v3 post请求

我正在尝试构建一个匿名上传到imgurapiv3的应用程序，这似乎会导致

NullPointerException

。我的清单中添加了互联网权限，所以我不确定为什么这不起作用。由于明显的原因，

客户端id

被删除。如有任何建议，将不胜感激

public HttpResponse uploadImage(String image_contents) {
    /* defining imgur api location */
    String API = ("https://api.imgur.com/3/image.json");
    Uri imgurAPI = (Uri.parse(API));

    // url encoding for bitmap

    // String dev_key = ("anon-dev-key-removed");
    String client_id = ("client-id-removed");
    /* String client_secret = ("secret-id-removed"); */
    /* constructing query */
    // spawning apache httpclient and post instance
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost(API);
    // defining namevaluepairs for post data and setting entity
    // httpclient help from this url:
    // http://www.vogella.com/articles/ApacheHttpClient/article.html
    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
    nameValuePairs.add(new BasicNameValuePair("image", image_contents));
    /* for debugging purposes */
    if (android.os.Build.VERSION.SDK_INT > 9) {
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
                .permitAll().build();
        StrictMode.setThreadPolicy(policy);
    }
    /* end for debugging purposes */
    try {
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
    } catch (UnsupportedEncodingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    // adding oauth2 header with clientid
    httppost.addHeader("Authorization", "Client-ID " + client_id);
    // execute the post and collect the response as a httpresponse object

    HttpResponse response = null;
    changeText(httppost.toString());
    try {
        response = httpclient.execute(httppost);
    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    /* shut down http client */
    httpclient.getConnectionManager().shutdown();

    return response;
}

最近可能已经改变了。。。但是使用ApacheHTTP客户端和IMGUR3.0API（至少在我为其编写代码时是这样）。您必须为HTTP客户端添加一些特殊的SSL处理代码。如果您不这样做，您的请求将失败：

 // io exception with the message: (hostname in certificate didn't match: <api.imgur.com>    != <imgur.com> OR <imgur.com>)

//io异常，消息为：（证书中的主机名不匹配：

在发出请求时（在catch块中），您是否看到任何异常？如果不是，可能SSL配置不再是一个问题。
u将需要发出HTTPS请求而不是HTTP bez您的Web服务url包含HTTPS协议而不是HTTP@ρ∑ρρK。我可能是错的，但我认为只要您提供正确的url，HttpClient就可以在本机上使用HTTPS。我只是通过切换到t来实现这一点他使用了IMGURAPIv2，但我不确定为什么它在版本3中不起作用。
 // io exception with the message: (hostname in certificate didn't match: <api.imgur.com>    != <imgur.com> OR <imgur.com>)
