Question

我在我的快递应用程序中设置响应标头如下：

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', 'Content-Type, Authorization');
  next();
});

然而，当服务器发送响应时，它们如下所示：

Response headers
0:A
1:c
10:t
11:r
12:o
13:l
14:-
15:A
16:l
17:l
18:o
19:w
2:c
20:-
21:M
22:e
23:t
24:h
25:o
26:d
27:s
3:e
4:s
5:s
6:-
7:C
8:o
9:n
Accept-Ranges:bytes
Access-Control-Allow-Headers:Content-Type, Authorization
Access-Control-Allow-Origin:*

有任何线索如何解决？

更改自：

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

到

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