如何启用DELETE请求？ [英] How to enable DELETE request?

问题描述

由于CORS，我无法允许我的API服务器发出删除请求。

I'm not able to allow the DELETE request from my API server due to CORS.

// enable CORS
app.use(function (req, res, next) {
    res.header("Access-Control-Allow-Origin", "*");
    res.header("Access-Control-Allow-Methods", "GET", "PUT", "POST", "DELETE", "OPTIONS");
    res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, Authorization");
    next();
});

我收到控制台错误消息：

I get a console error saying:

XMLHttpRequest无法加载http：// localhost：8080 / api / users / 57f5036645c04700128d4ee0。飞行前响应中Access-Control-Allow-Methods不允许方法DELETE

如何启用 DELETE 请求，就像 GET ， PUT 和 POST 请求？

How can I enable DELETE requests, just like GET, PUT, and POST requests?

推荐答案

我无需添加新软件包就解决了它，只是添加了这一行

I solved it without adding new packages, just added this line

res.header("Access-Control-Allow-Methods", "GET, PUT, POST, DELETE");

请注意，我在一个字符串中用逗号分隔了允许的方法。
完整功能如下：

Notice that i have my allowed methods separated by commas inside one string. The complete function looks like this:

app.use(function (req, res, next) {
  res.header("Access-Control-Allow-Origin", "*");
  res.header("Access-Control-Allow-Methods", "GET, PUT, POST, DELETE");
  res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, Authorization");
  next();
});
