Question

这是我的代码

    private void postToWall(String msg) {
    Bundle parameters = new Bundle();

    JSONObject attachment = new JSONObject();

    String myjosn="{\"name\":\"LangGuage\",\"href\":\"http://www.hunkatech.com\",\"caption\":\" \",\"description\":\""+messageToPost+"\",\"media\":[{\"type\":\"image\",\"src\":\"http://hwsdemos.com/LangGuage/medal_1.png\",\"href\":\"http://www.hunkatech.com\"}],\"properties\":{\"Powered by:\":{\"text\":\"Hunka Technology Pvt. Ltd.\",\"href\":\"http://www.hunkatech.com\"}}}";  

            try {



        parameters.putString(Facebook.TOKEN, facebook.getAccessToken());

            parameters.putString("attachment",myjosn.toString());


        String response = facebook.request("me/feed", parameters, "POST");

        System.out.println("----responce" + response);

        if (response.contains("Duplicate status message")) {
            progressHandler.sendEmptyMessage(1);
            resp = 1;

        } else if (response == null || response.equals("")
                || response.equals("false") || response.contains("error")) {
            Log.d("error", "error response");
        } else {
            progressHandler.sendEmptyMessage(0);
            resp = 0;

        }

    } catch (Exception e) {
        Log.e(TAG, "Posting fail");

        e.printStackTrace();

    }

}

我想在Facebook上发布带有图片的消息。我的json是正确的我已经在json格式化程序编辑器上检查了它。我得到了以下异常。需要建议如何解决它。

更新：借助以下代码发布了我的消息和图片：

parameters.putString("link", "http://www.hunkatech.com");
parameters.putString("picture", "http://hwsdemos.com/LangGuage/medal_1.png");
parameters.putString("name", "LangGuage");// name of link
parameters.putString("captions", "hello");
parameters.putString("message", "This is my message!!");

但是我希望将图像保留给文本，但是上面的代码将结果显示为Imgae以下消息。更新：我无法发布任何形式json.can任何人请解决这个问题我想发送附件绑定图像和massege与json。

Answer 1

您可以尝试另外添加此参数：

parameters.putString("message", "this is my message");

编辑：

你可以尝试：

parameters.putString("link", "http://www.hunkatech.com");
parameters.putString("picture", "http://hwsdemos.com/LangGuage/medal_1.png");
parameters.putString("name", "LangGuage");// name of link
parameters.putString("captions", "hello");
parameters.putString("message", "This is my message!!");

我是怎么做到的。

private void publishFeedDialog() {
        System.out.println("Working");
        Bundle postParams = new Bundle();
        postParams.putString("name", "I am an Engineer");
        postParams.putString("caption",
                "Working very heard to make things work.");
        postParams
                .putString("description",
                        "This project is killing me, Still I am trying, and finally I got success.");
        postParams.putString("link", "http://www.kodebusters.com");
        postParams
                .putString(
                        "picture",
                        "http://cdn1.iconfinder.com/data/icons/iconslandsport/PNG/128x128/Soccer_Ball.png");

        new MYasync(postParams).execute();

    }

在AsyncTask上运行网络调用，或者可以通过异常

运行

 class MYasync extends AsyncTask<Void, Void, Void> {

            Bundle params;
            private String res;

            public MYasync(Bundle params) {
                super();
                this.params = params;
            }

            @Override
            protected void onPostExecute(Void result) {
                System.out.println(res);
                super.onPostExecute(result);
            }

            @Override
            protected Void doInBackground(Void... pp) {
                try {
                    res = facebook.request("me/feed", params, "POST");

                } catch (FileNotFoundException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (MalformedURLException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
                return null;
            }

        }

{“error”：{“message”：“（＃100）缺少消息或附件”，“类型”：“OAuthException”，“code”：100}}
