如何使用Angularjs

Question

在angularjs如何加密和解密使用JSON令牌認證證書上基於令牌的認證工作。我使用Webapi和Mysql有沒有任何例子。

你可以使用angular-jwt module by auth0，它提供了一個decodeToken方法。

下面是它的文檔的爲例：

angular.module('app', ['angular-jwt']) 
.controller('Controller', function Controller(jwtHelper) { 
    var expToken = 'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJodHRwczovL3NhbXBsZXMuYXV0aDAuY29tLyIsInN1YiI6ImZhY2Vib29rfDEwMTU0Mjg3MDI3NTEwMzAyIiwiYXVkIjoiQlVJSlNXOXg2MHNJSEJ3OEtkOUVtQ2JqOGVESUZ4REMiLCJleHAiOjE0MTIyMzQ3MzAsImlhdCI6MTQxMjE5ODczMH0.7M5sAV50fF1-_h9qVbdSgqAnXVF7mz3I6RjS6JiH0H8'; 

    var tokenPayload = jwtHelper.decodeToken(expToken); 
}) 

這裏是the js code for this method：

angular.module('angular-jwt.jwt', []) 
.service('jwtHelper', function($window) { 

    this.urlBase64Decode = function(str) { 
     var output = str.replace(/-/g, '+').replace(/_/g, '/'); 
     switch (output.length % 4) { 
     case 0: { break; } 
     case 2: { output += '=='; break; } 
     case 3: { output += '='; break; } 
     default: { 
      throw 'Illegal base64url string!'; 
     } 
     } 
     return $window.decodeURIComponent(escape($window.atob(output))); //polyfill https://github.com/davidchambers/Base64.js 
    } 


    this.decodeToken = function(token) { 
     var parts = token.split('.'); 

     if (parts.length !== 3) { 
     throw new Error('JWT must have 3 parts'); 
     } 

     var decoded = this.urlBase64Decode(parts[1]); 
     if (!decoded) { 
     throw new Error('Cannot decode the token'); 
     } 

     return angular.fromJson(decoded); 
    } 


    });
