javascript - 无法在 node-cron 调度方法中获取数据

Question

所以我试图在每晚 12 点安排数据库中的更新，并且我能够使用我的服务器运行 Cron 作业，但我无法使用 Axios 获取数据，我尝试了“https”等教程中的外部 URL ://jsonplaceholder.typicode.com/posts/1"并且数据来了，但是当我使用 url/routes 我在 reactjs 前端获取数据时..像这样"http://localhost:9000/api/getAllDealHeader"并将其作为 URL 传递，它会给出类似的错误

我的代码是

const getData = async url => {
  try {
    const response = await axios.get(url);
    const data = response.data;
    console.log(data);
    } catch (error) {
       console.log(error);
   }
};


cron.schedule("59 * * * * *", () => {
     console.log("running a task every half minute");

     let url = 'http://localhost:9000/api/getAllDealHeader'
     getData(url);

})

我使用 MySQL 作为我的数据库，并将 sequelize 作为我的 ORM。
有人可以帮助我，我哪里出错了，我该怎么办..

Answer 1

您在函数中使用的变量名称不正确，它是小写的，但您在函数中使用了大写。

     cron.schedule("59 * * * * *",async () => {
   console.log("running a task every half minute");

   let url = 'https://jsonplaceholder.typicode.com/posts/1'
 await getData(url);

})
