使用fetch进行基本身份验证

Question

我想用fetch写一个简单的基本身份验证,但我一直收到401错误.如果有人告诉我代码有什么问题,那会很棒:

let base64 = require('base-64');

let url = 'http://eu.httpbin.org/basic-auth/user/passwd';
let username = 'user';
let password = 'passwd';

let headers = new Headers();

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

fetch(url, {method:'GET',
        headers: headers,
        //credentials: 'user:passwd'
       })
.then(response => response.json())
.then(json => console.log(json));
//.done();

function parseJSON(response) {
return response.json()
}

Answer 1

您缺少Basic编码的用户名和密码之间的空格.

headers.set('Authorization', 'Basic ' + base64.encode(username + ":" + password));

Answer 2

没有依赖关系的解决方案.

headers.set('Authorization', 'Basic ' + Buffer.from(username + ":" + password).toString('base64'));

Answer 3

复制粘贴到 Chrome 控制台的简单示例：

fetch('https://example.com/path', {method:'GET', 
headers: {'Authorization': 'Basic ' + btoa('login:password')}})
.then(response => response.json())
.then(json => console.log(json));

或与await：

let response = await fetch('https://example.com/path', {method:'GET', 
headers: {'Authorization': 'Basic ' + btoa('login:password')}});
let data = await response.json();
console.log(data);

Answer 4

您也可以使用btoa代替base64.encode（）。

headers.set('Authorization', 'Basic ' + btoa(username + ":" + password));

Answer 5

如果您有一个后端服务器在应用程序之前要求提供基本身份验证凭据，那么这就足够了，它将重新使用它：

fetch(url, {
  credentials: 'include',
}).then(...);

Answer 6

节点用户（反应、表达）遵循这些步骤

1. npm install base-64 --save
2. import { encode } from "base-64";

3.  const response = await fetch(URL, {
     method: 'post',
     headers: new Headers({
       'Authorization': 'Basic ' + encode(username + ":" + password),
       'Content-Type': 'application/json'
     }),
     body: JSON.stringify({
       "PassengerMobile": "xxxxxxxxxxxx",
       "Password": "xxxxxxx"
     })
   });
   const posts = await response.json();
   

4. 不要忘记将整个函数定义为 async
