okhttp发送请求并且添加header头

一:引入依赖

    com.squareup.okhttp3
    okhttp
    3.2.0
 

二:编写代码

import okhttp3.*;

import java.io.IOException;

public class HttpClient {

    private static OkHttpClient client = new OkHttpClient();

    public static void main(String[] args) throws IOException {

        //post请求
        FormBody formBody = new FormBody.Builder().add("code","1234").add("name","zp").add("age","25").build();

        Request request = new Request.Builder().url("http://127.0.0.1:8082/kabaouser/es/ok").
                addHeader("Access-User-Token","e5cHLWScbto3VfvYTU1llVZgl/WniA4QZZ8epmn8k/o=").post(formBody).build();

        client.newCall(request).enqueue(new Callback() {
            public void onFailure(Call call, IOException e) {
                System.out.println(e.getMessage());
            }

            public void onResponse(Call call, Response response) throws IOException {
                if(response.code() >= 200 && response.code() < 300) {
                    System.out.println(response.body().string());
                }
            }
        });

        //get请求
        Request request1 = new Request.Builder().url("http://www.baidu.com").build();
        client.newCall(request1).enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {
                System.out.println(e.getMessage());
            }

            @Override
            public void onResponse(Call call, Response response) throws IOException {
                if(response.code() >= 200 && response.code() < 300) {
                    System.out.println(response.body().string());
                }
            }
        });
    }
}

三:查看返回结果
