基于OWIN WebAPI 使用OAuth授权服务【客户端验证授权(Resource Owner Password Credentials Grant)】

适用范围

前面介绍了Client Credentials Grant ,只适合客户端的模式来使用,不涉及用户相关。而Resource Owner Password Credentials Grant模式中,用户向客户端提供自己的用户名和密码。客户端使用这些信息,向"服务商提供商"索要授权。

在这种模式中,用户必须把自己的密码给客户端,但是客户端不得储存密码。这通常用在用户对客户端高度信任的情况下,比如客户端是操作系统的一部分,或者由一个著名公司出品。而认证服务器只有在其他授权模式无法执行的情况下,才能考虑使用这种模式。这种模式会直接将用户密码暴露给应用程序,因此应谨慎使用。一般说来,只有信任度极高的客户才应授权使用该模式,如官方移动应用、操作系统或高权限程序。

            Figure 5: Resource Owner Password Credentials Flow

   The flow illustrated in Figure 5 includes the following steps:

   (A)  The resource owner provides the client with its username and
        password.

   (B)  The client requests an access token from the authorization
        server's token endpoint by including the credentials received
        from the resource owner.  When making the request, the client
        authenticates with the authorization server.

   (C)  The authorization server authenticates the client and validates
        the resource owner credentials, and if valid, issues an access
        token.

基本流程

基于OWIN WebAPI 使用OAuth授权服务【客户端验证授权(Resource Owner Password Credentials Grant)】

A. 向用户索要认证信息

首先,我们必须得让用户将认证信息提供给应用程序。对于应用方来说,如果用户处于不可信的网络中时,除了需要输入用户名和密码外,还需要用户提供一个安全令牌作为用户的第三个输入。

B. 交换访问令牌

这里的访问令牌交换过程与授权码类型的验证授权(authorization code)很相似。我们要做的就是向认证服务器提交一个POST请求并在其中提供相应的认证和客户信息。

所需的POST参数:
grant_type 该模式下为"password"
scope 业务访问控制范围,是一个可选参数
client_id 应用注册时获得的客户id
client_secret 应用注册时获得的客户密钥
username 用户的用户名
password 用户的密码

POST https://xxx.com/token HTTP/1.1
Content-type:application/x-www-form-urlencoded
Authorization Basic Base64(clientId:clientSecret)

username=irving&password=123456&grant_type=password

C. 刷新Token

1).accesstoken 是有过期时间的,到了过期时间这个 access token 就失效,需要刷新。
2).如果accesstoken会关联一定的用户权限,如果用户授权更改了,这个accesstoken需要被刷新以关联新的权限。
3).为什么要专门用一个 token 去更新 accesstoken 呢?如果没有 refreshtoken,也可以刷新 accesstoken,但每次刷新都要用户输入登录用户名与密码,客户端直接用 refreshtoken 去更新 accesstoken,无需用户进行额外的操作。

POST http://localhost:19923/token
Content-Type: Application/x-www-form-urlencoded Authorization Basic Base64(clientId:clientSecret) username=irving&password=123456&grant_type=refresh_token

备注:

有了前面相关token,服务调用也很简单

GET https://xxx.com/api/v1/account/profile HTTP/1.1
Content-type:application/x-www-form-urlencoded
Authorization Authorization: Bearer {THE TOKEN}
