【中文标题】如何修复来自 Apollo 客户端的格式错误的身份验证标头错误【英文标题】:How do I fix Malformed authentication header error coming from Apollo client 【发布时间】:2019-11-27 18:15:29 【问题描述】:我正在尝试使用 Apollo Client 将我的 react 应用程序连接到 hasura 后端 api,但我收到以下错误:
错误:GraphQL 错误:格式错误的授权标头
我不知道是什么原因造成的。
我知道我从 Cognito 获得了一个有效的 id 令牌,因为我可以将它粘贴到 Hasura 控制台中并且它工作正常。
我真的只是将 apollo 授权示例粘贴到我的 index.js 文件中并放入我的 uri。我开始使用 apollo-boost,但由于同样的错误而去了 apollo-client。这显然没有帮助。我搜索了互联网,找不到任何与此相关的内容,这可能意味着我在做一些愚蠢的事情。
这是我的 index.js 中的 apollo 客户端代码:
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import ApolloClient from 'apollo-client';
import createHttpLink from 'apollo-link-http';
import setContext from 'apollo-link-context';
import InMemoryCache from 'apollo-cache-inmemory';
import ApolloProvider from 'react-apollo';
import Auth from 'aws-amplify';
async function getSession()
Auth.currentSession().then(res=>
let idToken = res.getIdToken()
let jwt = idToken.getJwtToken()
//if I console log jwt here I can paste it into hasura and it works
return jwt
)
const token = getSession()
//copied from apollo docs:
const httpLink = createHttpLink(
uri: 'https://api.example.com/v1/graphql',
);
const authLink = setContext((_, headers ) =>
return
headers:
...headers,
authorization: token ? `Bearer $token` : "",
);
const client = new ApolloClient(
link: authLink.concat(httpLink),
cache: new InMemoryCache()
);
这是错误:

另外,我从浏览器收到错误,因为查询没有返回任何内容。
这是 chrome 控制台在 graphql 标头中的内容:

任何帮助将不胜感激。
【问题讨论】:
触发此错误的查询是标准查询还是订阅?此外,您显示的标头用于飞行前请求,而不是 actual 请求,后者应该是以下请求。您可以发布后续请求的标头(通常应包含您的“授权”标头)。 另外,您如何处理 API 端的“授权”标头? 【参考方案1】:分配给token
的值是Promise
类型,而不是您期望的字符串。
由于getSession()
是一个异步函数,因此它返回一个promise。
这一行:
const token = getSession()
将承诺而不是其解析值分配给token
。
在将结果分配给token
之前,您需要等待承诺解决。
