Question

在angularjs中，如何使用Json令牌身份验证加密和解密凭据。我正在使用Webapi和Mysql有任何例子。

Answer 1

您可以使用提供decodeToken方法的angular-jwt module by auth0。

以下是其文档中的示例：

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

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

这是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);
    }


  });
