未捕獲錯誤：n.onSuccess不是函數AWS Cognito

Question

當我嘗試使用新密碼設置已驗證的用戶並且無法確定它發生的位置時，出現以下javascript錯誤。一旦我打電話給我的註冊功能，用戶實際上可以用新的密碼覆蓋他們的臨時密碼，並且在Cognito控制檯中一切都很正常。他們也可以用他們的新密碼登錄。

我的寄存器功能：

import {Config, CognitoIdentityCredentials} from 'aws-sdk' 
import {CognitoUserPool, CognitoUser, AuthenticationDetails, CognitoUserAttribute} from 'amazon-cognito-identity-js' 

import jwtDecode from 'jwt-decode' 
import store from './store' 

export default class CognitoAuth { 

    register (username, email, pass, newPassword, cb) { 
    let authenticationDetails = new AuthenticationDetails({ 
     Username: username, 
     Password: pass 
    }) 
    let cognitoUser = new CognitoUser({ 
     Username: username, 
     Pool: this.userPool 
    }) 

    cognitoUser.authenticateUser(authenticationDetails, { 
     newPasswordRequired: (userAttributes, requiredAttributes) => { 

     // the api doesn't accept this field back 
     delete userAttributes.email_verified 

     cognitoUser.completeNewPasswordChallenge(newPassword, userAttributes, this) 
     } 
    }) 
    } 
} 

Register.vue

signup() { 
    this.$cognitoAuth.register(this.username, this.email, this.oldPass, this.newPass, (err, result) => { 
    if (err) { 
     this.error = true 
     this.errMsg = err.message 
     console.error(err) 
    } else { 
     console.log('Login Successful:', result) 
     this.$router.replace(this.$route.query.redirect || '/search') 
    } 
    }) 
}

你錯過了onSuccess回調實現，這就是所謂的用一個新的會話成功。請參閱CognitoUser.js中的第341行。

例如：

. 
. 
. 
cognitoUser.authenticateUser(authenticationDetails, { 
    onSuccess: (result) => { 
     // User authentication was successful. 
    }, 

    onFailure: (err) => { 
     // User authentication was not successful. 
    }, 

    mfaRequired: (codeDeliveryDetails) => { 
     // MFA is required to complete user authentication. 
     // Get the code from user and call: 
     cognitoUser.sendMFACode(mfaCode, this) 
    }, 

    newPasswordRequired: (userAttributes, requiredAttributes) => { 

     // the api doesn't accept this field back 
     delete userAttributes.email_verified; 

     cognitoUser.completeNewPasswordChallenge(newPassword, userAttributes, this); 
    } 
})
