我想将credential.access令牌存储在变量中，我尝试了以下操作，但未成功

Question

var Token; 
componentDidMount() {
  auth0.webAuth.authorize({
    scope: 'openid profile email',
    audience: 'https://MyDomain/userinfo' 
   })
   .then(credentials => 
      console.log(credentials.accessToken))
      this.key=credentials.accessToken;
 }

Answer 1

从ComponentDidMount看来这是个反应。

您似乎不是在回调内部执行this.key=credentials.accessToken，而是在外部执行。这意味着当您尝试设置this.key = credentials.accessToken;

时，凭据.accessToken将是未定义的。

Answer 2

尝试一下

var Token; 
componentDidMount() {
  auth0.webAuth.authorize({
    scope: 'openid profile email',
    audience: 'https://MyDomain/userinfo' 
   })
   .then(credentials => {
      console.log(credentials.accessToken);
      this.key=credentials.accessToken });
 }
