使用 OKHttpClient的POST方式

package com.qf.demo7;
// OKHttpClient  post
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/Day28_03/LoginServlet";

// 2 创建okhttpclient对象
OkHttpClient client = new OkHttpClient();

RequestBody body = new FormBody.Builder().add("useName", "addd").add("pwd", "12
bfc2
3").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();
}
}
}
