java以json格式向后台服务器接口发送请求的实例

代码如下：

import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

import net.sf.json.JSONObject;
public class InterfaceRequest {
    //模拟向腾讯云发送接口
    //接口
    private final static String URL = "https://console.tim.qq.com/v4/im_open_login_svc/account_import?";




    /**
     * @param args
     * @throws IOException
     */
    public static void main(String[] args) throws IOException {
        // TODO Auto-generated method stub
        //连接服务器
        HttpURLConnection connection = connection(URL);

        DataOutputStream out = new DataOutputStream(
                connection.getOutputStream());

        JSONObject obj = new JSONObject();

    obj.element("Identifier", "hehe");
        System.out.println(obj.toString());

        // 向腾讯请求传入编码为UTF-8格式的json数据
        out.write(obj.toString().getBytes("UTF-8"));


        out.flush();
        out.close();
        //获得服务器返回的结果
        BufferedReader reader = new BufferedReader(new InputStreamReader(
                connection.getInputStream()));
        String lines;
        StringBuffer sb = new StringBuffer("");
        while ((lines = reader.readLine()) != null) {
            lines = new String(lines.getBytes(), "utf-8");
            sb.append(lines);
        }

        reader.close();




    }

    public static HttpURLConnection connection(String URL
            ) throws IOException {
        URL url = new URL(URL);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoOutput(true);
        connection.setDoInput(true);
        connection.setRequestMethod("POST");
        connection.setUseCaches(false);
        connection.setInstanceFollowRedirects(true);
        connection.setRequestProperty("Content-Type",
                "application/x-www-form-urlencoded;charset=UTF-8");
        connection.connect();
        return connection;
        // TODO Auto-generated method stub
    }
}
