我有一个AngularJS WebAPI应用程序.

据我所知,OPTIONS请求是由浏览器自动构建的.

POST http://localhost:3048/Token HTTP/1.1
Host: localhost:3048
Connection: keep-alive
Content-Length: 78
Accept: application/json, text/plain, */*
Origin: http://localhost:2757
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95 Safari/537.36

Accept-Language: en-US,en;q=0.8

grant_type=password&username=xxx%40live.com&password=xxx

响应:

现在登录

我注销哪个只是删除令牌并再次登录.发生了不同的事情.在它没有发送OPTIONS之前,但现在确实如此.以前的请求/响应是否会导致浏览器在第二次登录时影响不同？

OPTIONS http://localhost:3048/Token HTTP/1.1 …

const URL = "http://url.com";
fetch(URL).then(res => res.json()).then(json => {
    this.setState({ someData: json });
});

如何发送带有 HTTP 标头的 HTTP 请求？
