Okhttp系列：POST请求

用Intelij Idea创建java项目，如下图：

添加阿里云镜像：

groovy 复制代码

maven { url 'https://maven.aliyun.com/repository/public/' }

添加Okhttp依赖：

groovy 复制代码

implementation 'com.squareup.okhttp3:okhttp:4.12.0'

java代码如下：

java 复制代码

package org.example;

import java.io.IOException;
import java.util.Collections;
import java.util.concurrent.TimeUnit;

import okhttp3.*;

public class PostExample {
  public static final MediaType JSON = MediaType.get("application/json; charset=utf-8");


  final OkHttpClient client = new OkHttpClient();


  String post(String url, String json) throws IOException {

    RequestBody body = RequestBody.create(json, JSON);
    Request request = new Request.Builder()
        .url(url)
        .post(body)
        .build();
    try (Response response = client.newCall(request).execute()) {
      return response.body().string();
    }
  }

  String bowlingJson(String player1, String player2) {
    return "{\"winCondition\":\"HIGH_SCORE\","
            + "\"name\":\"Bowling\","
            + "\"round\":4,"
            + "\"lastSaved\":1367702411696,"
            + "\"dateStarted\":1367702378785,"
            + "\"players\":["
            + "{\"name\":\"" + player1 + "\",\"history\":[10,8,6,7,8],\"color\":-13388315,\"total\":39},"
            + "{\"name\":\"" + player2 + "\",\"history\":[6,10,5,10,10],\"color\":-48060,\"total\":41}"
            + "]}";
  }

  public static void main(String[] args) throws IOException {
    PostExample example = new PostExample();
    String json = example.bowlingJson("Jesse", "Jake");
    String response = example.post("https://jsonplaceholder.typicode.com/posts", json);
    System.out.println(response);
  }
}

执行结果：
