针对REST API的授权会引发错误:401(未找到请求的凭据.) [英] Authorization against REST API throws an error: 401 (No credentials found the request.)

问题描述

我想针对HP Alm Rest API进行授权，我认为这种应该"有效，但事实并非如此:

I want to authorize against the HP Alm Rest API, I think this "should" work, but it does not:

function performSignIn(){

let headers = new Headers();

headers.append('Content-Type', 'application/json');
headers.append('Accept', 'application/json');
headers.append('Authorization', 'Basic ' + base64.encode(username + ":" + password));

fetch(sign_in, {mode: 'no-cors', method:'POST', headers: headers})
  .then(response => response.json())
  .then(json => console.log(json))
  .catch(error => console.log('Authorization failed : ' + error.message));
}

我收到一些奇怪的错误消息:

I get a bit weird error message:

401(没有凭据找到请求.)

这是HP文档中使用XMLHttpRequest完成的示例: http://alm-help.saas.hpe.com/de/12.53/api_refs/REST/webframe.htm#signin-out_example.htm

This is an example from the HP documentation, done with XMLHttpRequest: http://alm-help.saas.hpe.com/de/12.53/api_refs/REST/webframe.htm#signin-out_example.htm

有什么主意吗?我看不出有什么问题.

Any idea? I don't see what's wrong.

非常感谢！

最诚挚的问候，丹尼尔

推荐答案

fetch(...)默认情况下不会发送凭据.您需要明确指定应发送:

fetch(…) by default doesn’t send credentials. You need to explicitly specify they should be sent:

fetch(sign_in, {credentials: 'include' , method:'POST', headers: headers})
  .then(response => response.json())
  .then(json => console.log(json))
  .catch(error => console.log('Authorization failed : ' + error.message));
}

此外，顺便说一句，您绝对不想指定 mode:'no-cors'.这样做的结果是告诉浏览器阻止我的前端JavaScript访问此请求的响应.

Also, incidentally, you definitely don’t want to specify mode: 'no-cors'. The effect that has is to tell the browser, Block my frontend JavaScript from accessing the response from this request.
