Question

我想使用Android向网址发送http请求。我是iOS开发人员，现在正在尝试学习Android。我曾经在iOS中发送JSON字符串，如下所示

 {"function":"login", "parameters": {"username": "nithin""password": "123456"}}

如何在Android中发送此内容？我试过了List<NameValuePair>，但找不到合适的解决方案。

我尝试过的完整代码 -

    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost(URL);

    try {
        // Add your data
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("function", "login"));
        nameValuePairs.add(new BasicNameValuePair("username", "nithin"));
        nameValuePairs.add(new BasicNameValuePair("password", "123456"));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost);

    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
    } catch (IOException e) {
        // TODO Auto-generated catch block
    }

我觉得JsonStringer对你来说很简单实用..

试试这个：

   HttpPost request = new HttpPost(URL);
   request.setHeader("Accept", "application/json");
   request.setHeader("Content-type", "application/json");
   JSONStringer vm;
   try {
         vm = new JSONStringer().object().key("function")
        .value(login).key("parameters").object()
        .key("username")
        .value(nithin).key("password").value("123456")
        .endObject().endObject();
  StringEntity entity = new StringEntity(vm.toString());
  request.setEntity(entity);
  HttpClient httpClient = new DefaultHttpClient();
  HttpResponse response = httpClient.execute(request);

在android </namevaluepair>中创建一个带有List <namevaluepair>的json字符串
