Java之okhttp3请求方式-Toy模板网

这篇具有很好参考价值的文章主要介绍了Java之okhttp3请求方式。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

在java开发中，发起http请求是非常常见的需求，常用的有HttpClient，下面聊一下okhttp3的请求方式。
1、引入okhttp3依赖

		<dependency>
            <groupId>io.github.admin4j</groupId>
            <artifactId>http</artifactId>
            <version>0.4.0</version>
        </dependency>

2、提供springboot工程及http接口

@RestController
public class HelloController {

    /**
     * @description: get请求
     */
    @GetMapping("/hello")
    public String hello(@RequestParam String name) {
        return "hello," + name;
    }

    /**
     * @description: get请求
     */
    @GetMapping("hello2/{name}")
    public String hello2(@PathVariable("name") String name) {
        return "hello2," + name;
    }

    /**
     * @description: post请求
     */
    @PostMapping("hello3")
    public String hello3(@RequestBody Map map) {
        return map.get("name").toString();
    }

    /**
     * @description: form表单请求
     */
    @RequestMapping("hello4")
    public String hello4(@RequestParam Map map) {
        return map.get("name").toString();
    }

    /**
     * @description: post请求
     */
    @RequestMapping("hello5")
    public Object hello5(@RequestBody Map map) {
        return map;
    }
}

3、http请求

public class App {
    public static void main(String[] args) {
        System.out.println("Hello World!");
        // get
        //okhttp3.Response getResponse = HttpUtil.get("", Pair.of("", ""));
        JSONObject getResponse = HttpJsonUtil.get("http://localhost:8080/hello", Pair.of("name", "liubei"));
        System.out.println("get=" + getResponse);
        // post
        //okhttp3.Response postResponse = HttpUtil.post("", "");
        Map<String, Object> params = new HashMap<>(16);
        params.put("name", "admin");
        JSONObject postResponse = HttpJsonUtil.post("http://localhost:8080/hello3", params);
        System.out.println("post=" + postResponse);
        // form
        Map<String, Object> formParams = new HashMap<>(16);
        formParams.put("name", "sunquan");
        //okhttp3.Response formResponse = HttpUtil.postForm("", formParams);
        Object formResponse = HttpJsonUtil.postForm("http://localhost:8080/hello4", formParams);
        System.out.println("form=" + formResponse);

    }
}

4、请求结果
get请求
java okhttp,Java,java,okhttp3,http请求
post请求

form表单请求

可见发起http请求还是挺方便的，感兴趣的小伙伴可以试试~~~///(^v)\~~~文章来源地址https://www.toymoban.com/news/detail-539743.html
