问题描述

在前两篇博文中,对NodeJS Express应用 使用MSAL + AAD实现用户登录并获取用户信息,获取Authorization信息 ( ID Token, Access Token).

  1. 【Azure 应用服务】NodeJS Express + MSAL 应用实现AAD集成登录并部署在App Service Linux环境中的实现步骤
  2. 【Azure 应用服务】NodeJS Express + MSAL 应用实现AAD登录并获取AccessToken — cca.acquireTokenByCode(tokenRequest)

而在当前这篇博文中,我们将会实现以下目的:

1)为NodeJS API应用配置Bearer Token验证组件 passport 和 passport-azure-ad

2)实现使用idToken验证并访问API

《【Azure 应用服务】NodeJS Express + MSAL 实现API应用Token认证(AAD OAuth2 idToken)的认证实验 -- passport.authenticate(),【Azure 应用服务】NodeJS Express + MSAL 应用实现AAD集成登录并部署在App Service Linux环境中的实现步骤,【Azure 应用服务】NodeJS Express + MSAL 应用实现AAD登录并获取AccessToken -- cca.acquireTokenByCode(tokenRequest)》

 

 

实现步骤

在完成Azure AD中的注册应用配置后,并且根据博文“ NodeJS Express + MSAL 应用实现AAD登录并获取AccessToken — cca.acquireTokenByCode(tokenRequest): https://www.cnblogs.com/lulight/p/16357246.html” 完成用户登录的前端应用,

参考官方示例 “Enable authentication in your own Node.js web API by using Azure Active Directory B2C : https://docs.microsoft.com/en-us/azure/active-directory-b2c/enable-authentication-in-node-web-app-with-api” 准备API端的代码。

 

第一步:下载示例代码

git clone https://github.com/Azure-Samples/active-directory-b2c-javascript-nodejs-webapi.git

Install app dependencies

cd active-directory-b2c-javascript-nodejs-webapi

npm install

npm update

下载后的文件结构为:

第二步:修改config.json 文件和index.js中的 identityMetadata 值

options中即为 BearerStrategy的配置参数,因为当前不适用AAD B2C,而是直接使用AAD,所以isB2C就需要设置为false,

const options = {
    identityMetadata: 'https://login.partner.microsoftonline.cn/xxxxxxxx-66d7-xxxx-8f9f-xxxxxxxxxxxx/v2.0/.well-known/openid-configuration',
    clientID: ##clientID,
    audience: ##clientID,
    validateIssuer: true,
    loggingLevel: 'info',
    passReqToCallback: false
}

因为参考文档中使用的试AAD B2C来认证Token,而本示例中使用的是AAD来认证Token,所以很多参数配置有一点差别。

本次实验中使用的参数说明如下:

  • identityMetadata (必须字段):填写进行OAuth 2.0 认证的 Openid-configuration地址,如在中国区的地址为  ‘https://login.partner.microsoftonline.cn/<your tenant id>/v2.0/.well-known/openid-configuration’
  • clientID (必须字段): 为AAD中注册应用的Application ID
  • audience(可选):为一个字符串或者字符串数组,默认值为注册应用的Client ID
  • validateIssuer(可选):如果不需要验证Issuer这个参数,需要设置为false。默认值为true。当使用AAD的Openid-configuration信息,它会通过identitymetadata中获取 issuer信息
  • loggingLevel(可选):AAD Validation 的日志输出级别,有info,error,warn可供设置
  • passReqToCallback(可选):默认值为false,用户当请求的第一个参数中提供了验证函数时,需要设置为true

关于BearerStrategy参数更多详细说明请参考链接:https://github.com/AzureAD/passport-azure-ad#42-bearerstrategy

 

第三步:访问API接口(/hello 需要Authorization, /public 不需要Authorization)

在index.js代码中,实现了两个接口 /hello 和 /public。 /hello 接口添加了passport.authenticate认证,访问需要携带Authorization (JWT Token),而/public则无需认证。

//<ms_docref_protected_api_endpoint>
// API endpoint, one must present a bearer accessToken to access this endpoint
app.get('/hello',
    passport.authenticate('oauth-bearer', {session: false}),
    (req, res) => {
        console.log(req.headers.authorization);
        console.log('Validated claims: ', req.authInfo);
    
          
        // Service relies on the name claim.  
        res.status(200).json({'name': req.authInfo['name']});
    }
);
//</ms_docref_protected_api_endpoint>

//<ms_docref_anonymous_api_endpoint>
// API anonymous endpoint, returns a date to the caller.
app.get('/public', (req, res) => res.send( {'date': new Date() } ));
//</ms_docref_anonymous_api_endpoint>

第四步:验证 idToken 和 accessToken 

在前端UI页面通过登录后获取到Token信息, http://localhost:3000/auth

GET /hello 200 11.557 ms - 16

 

[可选]第五步:修改AAD注册应用的accessTokenAcceptedVersion 

因为中国区AAD目前生成的Token为OAuth v1.0, 而在API应用中 identityMetadata  使用的是v2.0的openid-configration。所以需要在ADD中修改当前注册应用的清单文件(Mainfest)中

accessTokenAcceptedVersion 值为 2 
《【Azure 应用服务】NodeJS Express + MSAL 实现API应用Token认证(AAD OAuth2 idToken)的认证实验 -- passport.authenticate(),【Azure 应用服务】NodeJS Express + MSAL 应用实现AAD集成登录并部署在App Service Linux环境中的实现步骤,【Azure 应用服务】NodeJS Express + MSAL 应用实现AAD登录并获取AccessToken -- cca.acquireTokenByCode(tokenRequest)》

  1. 登录Azure 门户,选择Azure AD。
  2. 点击 App registrations 并选择自己的应用,如本示例中的“ExpressWebApp”
  3. 进入应用Overview页面后,选择左侧导航中“Manifest”清单页面。修改 accessTokenAcceptedVersion 的值为2,保存即可。
