OkHttpClient如何实现一个POST请求呢?

OkHttpClient之POST请求的实现思路

1.引入OkHttpClient对应的jar包
2.声明OkHttpClient对象
3.定义一个RequestBody,并将参数放入到RequestBody中
3.使用OkHttpClient对象的build()方法构建对象
   并采用post的方式放入body
4.使用execute方法,即可发起OkHttpClient请求

package com.java265;

import java.io.IOException;

import okhttp3.FormBody;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;

public class Test3 {

    public static void main(String[] args) {
        String path = "http://localhost:8080/Test/LoginServlet";
        
        // 2 创建okhttpclient对象
        OkHttpClient client = new OkHttpClient();
        
        RequestBody body = new FormBody.Builder().add("useName", "java").add("pwd", "123456").build();
        // 3 创建请求方式
        Request request = new Request.Builder().url(path).post(body).build();
        
        // 4 执行请求操作
        try {
            Response response = client.newCall(request).execute();
            if(response.isSuccessful()){
                String string = response.body().string();
                System.out.println(string);
            }
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}
