如图所示的俩个控制台功能，调用腾讯云的接口执行这俩个动作 （代码可以优化）nodejs框架是express, 这里粘贴调用成功的代码示例，做个记录。

app.get('/PurgeUrlsCache', async function (req, res, next) {
	// Depends on tencentcloud-sdk-nodejs version 4.0.3 or higher
const client = new tencentcloud.cdn.v20180606.Client({
  credential: {
    secretId: "XXX",
    secretKey: "XXX",
  },
  region: "",
  profile: {
    signMethod: "TC3-HMAC-SHA256",
    httpProfile: {
      reqMethod: "POST",
      reqTimeout: 30,
      endpoint: "cdn.tencentcloudapi.com",
    },
  },
})

const params = {
    "Urls": [
        req.query.url
    ]
};
// 清除CDN缓存
client.PurgeUrlsCache(params).then(
  (data) => {
    console.log(data);
  res.send(data);
  },
  (err) => {
    console.error("error", err);
  }
);


})



app.get('/urlspushcache', async function (req, res, next) {
	// Depends on tencentcloud-sdk-nodejs version 4.0.3 or higher
const client = new tencentcloud.cdn.v20180606.Client({
  credential: {
    secretId: "xxx",
    secretKey: "xxx",
  },
  region: "",
  profile: {
    signMethod: "TC3-HMAC-SHA256",
    httpProfile: {
      reqMethod: "POST",
      reqTimeout: 30,
      endpoint: "cdn.tencentcloudapi.com",
    },
  },
})

const params = {
    "Urls": [
        req.query.url
    ]
};
// 重新刷新预热
client.PushUrlsCache(params).then(
  (data) => {
    console.log(data);
  res.send(data);
  },
  (err) => {
    console.error("error", err);
  }
);


})
