[网络协议]java基于hutool发起http请求

一、添加依赖

hutool依赖，junit依赖

<dependency>
    <groupId>cn.hutool</groupId>
    <artifactId>hutool-all</artifactId>
    <version>5.4.5</version>
</dependency>
<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.13.2</version>
    <scope>test</scope>
</dependency>

二、get和post参数请求方式

    
     /**
     * 请求地址
     * https://my.fengniao.com/info.php?userid=604583
     */
    @Test
    public void testGetParam() {
        HashMap<String, Object> paramMap = new HashMap<>();
        paramMap.put("userid", "604583");
        String result = HttpUtil.get("https://my.fengniao.com/info.php", paramMap);
        System.out.println(result);
    }

    /**
     * 请求地址
     * https://ug.baidu.com/mcp/pc/pcsearch
     * 参数格式
     * {"invoke_info":{"pos_1":[{}],"pos_2":[{}],"pos_3":[{}]}}
     * 响应如下
     * {"errno":0,"errmsg":"ok","data":{"log_id":"89413141308091000","action_rule":{"pos_1":[],"pos_2":[],"pos_3":[]}}}
     */
    @Test
    public void testPostParam() {
        String body = "{\"invoke_info\":{\"pos_1\":[{}],\"pos_2\":[{}],\"pos_3\":[{}]}}";
        String result = HttpUtil.post("https://ug.baidu.com/mcp/pc/pcsearch", body);
        System.out.println(result);
    }


     /**
     * 自定义header的方式请求方法
     *
     * @throws Exception
     */
    @Test
    public void testHttps() throws Exception {
        String json = "{\"invoke_info\":{\"pos_1\":[{}],\"pos_2\":[{}],\"pos_3\":[{}]}}";
        String result = HttpRequest.post("https://ug.baidu.com/mcp/pc/pcsearch")
                .header("Content-Type", "application/json")
                //.setHttpProxy("127.0.0.1", 9080)  //配置代理
                .body(json)
                .execute().body();
        System.out.println(result);
    }
