在黑莓的Json发送/ POST错误 [英] Json Send/Post error in blackberry

问题描述

我想通过HttpConnection的发送JSON请求，但我得到的错误，当我试图得到响应code。
这里是我的code ...

I want to send JSON request through HTTPConnection but i am getting error when i am trying to get the response code. Here is my code...

public void sendrequest(String url)throws IOException, JSONException
{
        JSONObject postObject = new JSONObject();

        postObject.put("method", method);

        postObject.put("params", Parameters);

        HttpConnection c = (HttpConnection)Connector.open(url);

        c.setRequestMethod(HttpConnection.POST);

            c.setRequestProperty("Content-Type", "application/json;charset=UTF-8");

            c.setRequestProperty("Content-Length", "" + (postObject.toString().length() - 2));
            c.setRequestProperty("method", method);

            c.setRequestProperty("params", Parameters);

            rc = c.getResponseCode();

            if (rc != HttpConnection.HTTP_OK){

                throw new IOException("HTTP response code: " + rc);
            }
}

我得到这个code从<一个href=\"http://%22http://stackoverflow.com/questions/9339656/send-json-request-from-blackberry-application%22%20but%20never%20understood%20what%20is%20value%20of%20the%20variable\"

i get this code from Send JSON request from blackberry used in postObject.put("method", method);

推荐答案

的值法是字符串指定请求方法 HttpConnection.GET 或 HttpConnection.POST 。

The value of method is a String to specify the request method HttpConnection.GET or HttpConnection.POST.

您必须指定它喜欢：

c.setRequestProperty("method", HttpConnection.GET);

或

c.setRequestProperty("method", HttpConnection.POST);

您可以使用<一个href=\"http://www.blackberry.com/developers/docs/5.0.0api/javax/microedition/io/HttpConnection.html#setRequestMethod%28java.lang.String%29\"相对=nofollow> c.setRequestMethod（）代替
