本文介绍了如何使用OKHttp和HttpClient发送POST网络请求并接收JSON格式的响应。通过两个具体的示例代码展示了参数设置及请求执行过程。



OKHttp发送网络post请求,返回一个jsonString的模板:

OkHttpClient okHttpClient = new OkHttpClient();
FormEncodingBuilder builder = new FormEncodingBuilder();
builder.add("username", name);
builder.add("pwd", pwd);
//创建一个请求对象
Request request = new Request.Builder()
        .url(Constants.URLS.LOGIN_URL)
        .post(builder.build())
        .build();
//发送请求获取响应
    Response response = okHttpClient.newCall(request).execute();
        String json = response.body().string();
       
        Gson gson = new Gson();
        ResultBean resultBean = gson.fromJson(json, ResultBean.class);
        return resultBean;
    }




HttpClient发送网络post请求,返回一个jsonString的模板:
         HttpClient client = new DefaultHttpClient();
         // 创建一个Post请求
         HttpPost post = new HttpPost(url);
         // 将参数设置到Post请求里面
         List<NameValuePair> params = new ArrayList<NameValuePair>();
         params.add(new BasicNameValuePair("username", name));
         params.add(new BasicNameValuePair("pwd", pwd));
         HttpEntity entity = new UrlEncodedFormEntity(params);         post.setEntity(entity);//       执行一个Post请求         HttpResponse response = client.execute(post);         if (response.getStatusLine().getStatusCode()==200) {            InputStream is = response.getEntity().getContent();            BufferedReader reader=new BufferedReader(new InputStreamReader(is));            return reader.readLine();         }
}
