Question

我正在尝试使用javascript的Authorization标头发送一个http POST，并发现许多答案推荐此配置

var device_address = 10.25.148.164;
var device_login = myusername;
var device_password = mypassword;
var xhr = new XMLHttpRequest();
xhr.open('POST', 'http://' + device_address + '/rest/conf', true);
xhr.setRequestHeader('Authorization', 'Basic ' + btoa(device_login + ':' + device_password));
xhr.send();

以上配置对我不起作用，我得到状态码401：未经授权＆＃34; ;从Wireshark数据包捕获，我看到以下

Hypertext Transfer Protocol
OPTIONS /rest/conf HTTP/1.1\r\n
    [Expert Info (Chat/Sequence): OPTIONS /rest/conf HTTP/1.1\r\n]
        [OPTIONS /rest/conf HTTP/1.1\r\n]

\r\n
[Full request URI: http://10.25.148.164/rest/conf]
[HTTP request 1/1]

但是，如果我从Postman发送POST它可以工作，Wireshark数据包捕获显示以下

Hypertext Transfer Protocol
POST /rest/conf HTTP/1.1\r\n

\r\n
[Full request URI: http://10.25.148.164/rest/conf]

我尝试了window.btoa而不是btoa，我尝试添加

xhr.setRequestHeader('Content-Type', 'application/json');
xhr.setRequestHeader('Accept', 'application/json');

但没有任何效果。

任何人都可以告诉我我错过了什么？

我使用了一个登台服务器并启用了Access-Control-Allow-Origin：*，但响应仍然是401 Unauthorized
