我正在按照以下示例在新的Expo应用上实现Auth0身份验证: https://github.com/expo/auth0-example
似乎调用了Auth0并成功获取了令牌,但是在控制台中记录响应后,它立即也给了我以下错误:
可能的未处理的承诺拒绝(id:0)[InvalidTokenError: 指定的令牌无效:JSON中位置0处的令牌V异常]
我得到的答复是:
params:
access_token: “Vku7HOclH7pVi52bmzGHga89VwpfK_Y4”
exp://10.0.0.215:19000/–/expo-auth-session: “”
expires_in: “7200”
scope: “openid profile”
token_type: “Bearer”
proto: Object
type: “success”
url: “exp://10.0.0.215:19000/–/expo-auth-session#access_token=Vku7HOclH7pVi52bmzGHga89VwpfK_Y4&scope=openid%20profile&expires_in=7200&token_type=Bearer”
当我检查jwt.io上的access_token
时,表明签名无效。知道这里可能是什么问题吗?
这是我的完整代码:
import React, { Component } from 'react';
import { AuthSession } from 'expo';
import { Alert, Button, View, Text } from 'react-native';
import jwtDecoder from 'jwt-decode';
import styles from '../constants/styles';
const auth0ClientId = 'my_client_id_for_my_mobile_app_from_Auth0_dashboard';
const auth0Domain = 'https://mydomain.auth0.com';
/**
* Converts an object to a query string.
*/
function toQueryString(params) {
return '?' + Object.entries(params)
.map(([key, value]) => `${encodeURIComponent(key)}=${encodeURIComponent(value)}`)
.join('&');
}
export default class Login extends Component {
constructor(props) {
super(props);
this.state = {
username: null
};
}
_loginWithAuth0 = async () => {
const redirectUrl = AuthSession.getRedirectUrl();
console.log(`Redirect URL (add this to Auth0): ${redirectUrl}`);
const result = await AuthSession.startAsync({
authUrl: `${auth0Domain}/authorize` + toQueryString({
client_id: auth0ClientId,
response_type: 'token',
scope: 'openid profile',
redirect_uri: redirectUrl,
}),
});
console.log(result);
if (result.type === 'success') {
this.handleParams(result.params);
}
}
handleParams = (responseObj) => {
if (responseObj.error) {
Alert.alert('Error', responseObj.error_description
|| 'something went wrong while logging in');
return;
}
const encodedToken = responseObj.access_token;
const decodedToken = jwtDecoder(encodedToken, { header: true });
const username = decodedToken.name;
debugger;
this.setState({ username });
}
render() {
return (
<View style={styles.welcomeScreen}>
<Text>Welcome to My Expo App!</Text>
<Button title="Login with Auth0" onPress={this._loginWithAuth0} />
</View>
);
}
}
P.S。我的Expo应用程序使用的是SDK版本31.0.0
答案 0 :(得分:0)
非定制API的访问令牌是不透明的(类似于您收到的令牌),而不是JWT。这是因为您尚未在授权URL中设置audience
。 Auth0仅提供JWT Access Tokens用于自定义API。
由于您请求openid
范围,因此您收到的ID令牌将采用JWT格式。
