Wie nutzt das SpringBoot-Projekt das Hutool-Tool, um HTTP-Schnittstellenaufrufe durchzuführen?

hutool简单介绍

关于hutool工具包其实本人使用的不多哈 ，这里面其实封装处理了大量的开发日常小工具方法：

• 时间格式化，时间转换，时间校验

• http 接口调用

• 字符串格式化处理

• 国标加密....

对于一个稍微大型的项目来说是一个很好用的封装工具包('宝藏男孩'),更多的好东西需要大家去探索

实践

这里说明一下hutool封装了httpclient 也是能使用的但是它高度封装了，所以我使用的是

HttpRequest

灵活性更高！！！

post

简单接口调用

@Test
public void huToolPost() {
    System.out.println("--------------------------------post请求-----------------------------------");
    HashMap<String, String> paramMaps = new HashMap<>(4);
    paramMaps.put("pid", "463669875660294144");
    paramMaps.put("mobile", "123456.");
    paramMaps.put("name", "123456.");
    paramMaps.put("message", "");
    HttpResponse response = HttpRequest.post("http://192.168.99.202:8202/thySystem/pg-biz-sae/app/opinion/add")
            .header("Content-Type", "application/json")
            .header("token", "710515329923024896")
            .header("kong-request-id", "710515329923024896")
            .body(JSON.toJSONString(paramMaps))
            .execute();

    int status = response.getStatus();
    System.out.println("请求响应状态码:" + status);
    String body = response.body();
    System.out.println(body);
    JSONObject jsonObject = JSONObject.parseObject(body);
    Object msg = jsonObject.get("msg");
    System.out.println(msg);
    Object code = jsonObject.get("code");
    System.out.println(code);

}

文件上传

/**
 * 文件上传测试
 */
@Test
public void huToolUploadFile(){
    File f1 = new File("C:\Users\12043\Desktop\cat.jpeg");
    File f2 = new File("C:\Users\12043\Desktop\cat.jpeg");
    File[] files = new File[2];
    files[0] = f1;
    files[1] = f2;
    HttpResponse response = HttpRequest.post("url")
            .form("param", "test")
            .form("key", files)
            .execute();
}

get 请求

@Test
public void huToolGet(){
    System.out.println("--------------------------------get请求-----------------------------------");
    HashMap<String, Object> getParamMaps = new HashMap<>(5);
    getParamMaps.put("sortStr", "recordFlag,baseInfo.createTime");
    getParamMaps.put("sortDirection", "ASC");
    getParamMaps.put("filterStr", "flowAbleInfo.nodeId==craCheck");
    getParamMaps.put("pageSize", 10);
    getParamMaps.put("pageNo", 0);
    HttpResponse getResponse = HttpRequest.get("http://192.168.99.202:8202/thySystem/pg-biz-sae/sae/list")
            .header("Content-Type", "application/json")
            .header("token", "710515329923024896")
            .header("kong-request-id", "710515329923024896").form(getParamMaps).execute();

    int status1 = getResponse.getStatus();
    System.out.println("请求响应状态码:" + status1);
    String body1 = getResponse.body();
    System.out.println(body1);
    JSONObject jsonObject1 = JSONObject.parseObject(body1);
    Object msg1 = jsonObject1.get("msg");
    System.out.println(msg1);
    Object code1 = jsonObject1.get("code");
    System.out.println(code1);
}
