AXIOS 请求：“错误：连接 ECONNREFUSED 127.0.0.1:80”

Question

试图了解我的 GET 请求发生了什么。我使用 node.js 在后端进行了设置。我一开始以为我使用了错误的 .env、url、用户名和密码……但是当我检查 Postman 时，Basic Auth 似乎可以毫无问题地获取 JSON 数据。我使用 AXIOS 错了吗？

这是我的 GET 请求：

let customers;
try {
    let user_res = await axios({
        method: "GET",
        url: "api._____.com/customers",
        auth: {
            username: process.env.USERNAME,
            password: process.env.PASSWORD
        }
    });
    customers = user_res.data;
    console.log(customers);
} catch (err) {
    const error = new HttpError(
        "API failed, please try again.",
        500
    );
    return next(error);
}

Answer 1

我知道您的网址定义如下：api.___.com/customers，但是您应该将其定义为http://api.___.com/customersorhttps://api.___.com/customers如果您有的话。

Answer 2

那么，127.0.0.1 意味着它被您的本地计算机 (127.0.0.1) 在端口 80 上拒绝。也许您需要向本地计算机的该端口添加例外？另一件需要注意的事情是，如果您的服务器本身存在 CORS 问题，但通常会遇到详细说明这种情况的错误。
