网址： http://jon2012.com/api/register 方法：POST 头：否标头，因为它们不要求 数据：{电子邮件：[e-mail]，FIRST_NAME：姓名}

Android的code：

Android Code:

HttpClient client = new DefaultHttpClient();
        HttpConnectionParams.setConnectionTimeout(client.getParams(), 10000); //Timeout Limit
        HttpResponse response;
        JSONObject json = new JSONObject();
        try{
            HttpPost post = new HttpPost(url);
            json.put("email", email);
            json.put("first_name", name);
            StringEntity se = new StringEntity( "JSON: " + json.toString());  
            se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
            post.setEntity(se);
            response = client.execute(post);
            /*Checking response */
            /*if(response!=null){
                InputStream in = response.getEntity().getContent(); //Get the data in the entity
*/
            int statusCode = response.getStatusLine().getStatusCode();

        }
        catch(Exception e){
            e.printStackTrace();
           // createDialog("Error", "Cannot Estabilish Connection");
        }

推荐答案

我正在JSON对象的一个​​常见的​​错误顺序是错误的。 例如，我会发送它像 FIRST_NAME，email..etc..where为正确顺序为电子邮件，FIRST_NAME

i was making a common mistake sequence of json object was wrong. for example i was sending it like first_name,email..etc..where as correct sequence was email,first_name

我的code

boolean result = false;
        HttpClient hc = new DefaultHttpClient();
        String message;

        HttpPost p = new HttpPost(url);
        JSONObject object = new JSONObject();
        try {

            object.put("updates", updates);
            object.put("mobile", mobile);
            object.put("last_name", lastname);
            object.put("first_name", firstname);
            object.put("email", email);

        } catch (Exception ex) {

        }

        try {
        message = object.toString();


        p.setEntity(new StringEntity(message, "UTF8"));
        p.setHeader("Content-type", "application/json");
            HttpResponse resp = hc.execute(p);
            if (resp != null) {
                if (resp.getStatusLine().getStatusCode() == 204)
                    result = true;
            }

            Log.d("Status line", "" + resp.getStatusLine().getStatusCode());
        } catch (Exception e) {
            e.printStackTrace();

        }

        return result;
