Volo.Abp的 身份服务器模块默认使用 IdentityServer4实现身份认证。
IdentityServer4是一个开源的OpenID Connect和OAuth 2.0框架，它实现了这些规范中的所有必需功能。
OAuth 2.0支持多种认证模式，本文主要介绍客户端授权模式认证。客户端授权模式流程如下图所示：
（A）用户访问客户端，后者将前者导向认证服务器。
（B）用户选择是否给予客户端授权。
（C）假设用户给予授权，认证服务器将用户导向客户端事先指定的"重定向URI"（redirection URI），同时附上一个授权码。
（D）客户端收到授权码，附上早先的"重定向URI"，向认证服务器申请令牌。这一步是在客户端的后台的服务器上完成的，对用户不可见。
（E）认证服务器核对了授权码和重定向URI，确认无误后，向客户端发送访问令牌（access token）和更新令牌（refresh token）。
更多关于OAuth 2.0的介绍，可以参考阮一峰的理解OAuth 2.0。
注册Client
Client是第三方应用，它获得资源所有者的授权后便可以去访问资源。通常第三方登录中的第三方应用就是Client。如微博登录、QQ登录等。
要使用OAuth API需要先注册Client。通常，授权服务器需要提供一个管理页面，其中设置第三方应用的信息，包括应用名称、应用网站地址、应用简介、应用logo、授权回调地址等。
在本示例中，Client的注册是通过SeedData实现的。SeedData是在应用启动时自动执行的，它可以用来初始化数据库，如创建初始用户、角色、权限、和创建Client。
使用Abp.Cli创建一个认证服务分离的项目，
在认证服务项目AuthServer中打开appsettings.json，将vue的地址（http://localhost:8081）配置到ClientUrl和RedirectAllowedUrls
"App": {
"SelfUrl": "https://localhost:44350",
"ClientUrl": "http://localhost:8081",
"CorsOrigins": "https://*.Matoapp.com,https://localhost:44328,https://localhost:44377,http://localhost:8081,http://localhost:8082,http://localhost:8083",
"RedirectAllowedUrls": "http://localhost:8081/continue,https://localhost:44380,https://localhost:44328,https://localhost:44369"
},
项目中已经包含了一个SeedData类和一些配置，我们需要理解并修改这些配置。
我们将创建一个名为Matoapp的Client
appsettings.json配置如下
"OpenIddict": {
"Applications": {
"Matoapp_App": {
"ClientId": "Matoapp_App",
"RootUrl": "http://localhost:8081"
},
...
}
}
在OpenIddictDataSeedContributor中配置ClientType为public；
grantTypes为authorization_code和password；
scopes为该项目的服务名称以及需要的额外userinfo信息；
redirectUri客户端的回调地址。设置为http://localhost:8081/continue。
完整的CreateApplicationsAsync方法如下：
private async Task CreateApplicationsAsync()
{
var commonScopes = new List<string>
{
OpenIddictConstants.Permissions.Scopes.Address,
OpenIddictConstants.Permissions.Scopes.Email,
OpenIddictConstants.Permissions.Scopes.Phone,
OpenIddictConstants.Permissions.Scopes.Profile,
OpenIddictConstants.Permissions.Scopes.Roles,
"Matoapp",
};
var configurationSection = _configuration.GetSection("OpenIddict:Applications");
//Console Test / Angular Client
var consoleAndAngularClientId = configurationSection["Matoapp_App:ClientId"];
if (!consoleAndAngularClientId.IsNullOrWhiteSpace())
{
var consoleAndAngularClientRootUrl = configurationSection["Matoapp_App:RootUrl"]?.TrimEnd('/');
await CreateApplicationAsync(
name: consoleAndAngularClientId!,
type: OpenIddictConstants.ClientTypes.Public,
consentType: OpenIddictConstants.ConsentTypes.Implicit,
displayName: "Console Test / Angular Application",
secret: null,
grantTypes: new List<string>
{
OpenIddictConstants.GrantTypes.AuthorizationCode,
OpenIddictConstants.GrantTypes.Password,
},
scopes: commonScopes,
redirectUri: $"{consoleAndAngularClientRootUrl}/continue",
clientUri: consoleAndAngularClientRootUrl,
postLogoutRedirectUri: consoleAndAngularClientRootUrl,
permissions: new List<string> {
OpenIddictConstants.Permissions.Scopes.Roles,
OpenIddictConstants.Permissions.Scopes.Profile,
OpenIddictConstants.Permissions.Scopes.Email,
OpenIddictConstants.Permissions.Scopes.Address,
OpenIddictConstants.Permissions.Scopes.Phone,
"Matoapp",
}
);
}
...
}
OAuth2.0授权
我们将使用oidc-client-ts简化Vue中的OAuth2.0授权。有关oidc-client-ts的更多信息，请参阅oidc-client-ts
创建一个vue项目，前端使用element-ui
安装oidc-client-ts
yarn add oidc-client-ts
创建vue-oidc-client
创建vue-oidc-client.ts文件，编写代码如下：
// vue 2 version
import Router from 'vue-router'
import Vue from 'vue'
import {
UserManagerSettings,
Log,
User,
UserManager,
UserProfile,
WebStorageStateStore,
UserManagerEvents
} from 'oidc-client-ts'

}

export enum LogLevel {
/**

这里基于vue-oidc-client进行修改，因为vue-oidc-client是基于oidc-client，而oidc-client已经不再维护，所以我们使用oidc-client-ts
创建OAuth2.0认证跳转
在登录页面login/index.vue中，添加Auth2.0认证跳转按钮
<el-row
type="flex"
class="row-bg"
justify="center"
:gutter="10"
>
<el-col :span="10">
<el-button
:loading="loading"
type="primary"
@click.native.prevent="handleLogin"
>
登录
</el-button>
</el-col>
<el-col :span="10">
<el-button
:loading="loading"
@click.native.prevent="handleLoginAuth2"
>
Auth2.0
</el-button>
</el-col>
</el-row>
</el-form>
点击跳转后，自动跳转到认证服务器的登录页面
当正确输入用户名和密码后，跳转到客户端的回调地址，并携带授权码code参数
环境变量中配置CLIENT_ID，资源服务器地址和认证服务器地址
VUE_APP_BASE_API = 'https://localhost:44377/'
VUE_APP_BASE_IDENTITY_SERVER = 'https://localhost:44350/'
VUE_APP_CLIENT_ID = 'Matoapp_App'
在login/index.vue中添加handleLoginAuth2方法
注意此处的redirect_uri要和认证服务器中的配置一致，否则跳转时会引发400 Bad Request
async handleLoginAuth2() {
var loco = window.location;
var appRootUrl = `${loco.protocol}//${loco.host}`;
var idsrvAuth = createOidcAuth("main", SignInType.Window, appRootUrl, {
authority: baseUrl,
client_id: "Matoapp_App", // 'implicit.shortlived',
response_type: "code",
scope: "Matoapp",
// test use
prompt: "login",
metadata: {
issuer: baseUrl,
authorization_endpoint: `${baseUrl}connect/authorize`,
end_session_endpoint: `${baseUrl}logout`,
token_endpoint: `${baseUrl}connect/token`,
},
redirect_uri: appRootUrl + "/continue",
disablePKCE: true,
});
await idsrvAuth.signIn();
}
获取令牌
获取完成授权码后，需要通过授权码获取令牌（Token），此处将调用后端的接口，认证服务器核对了授权码和重定向URI后发放令牌
function Login(data, baseURL?: string) {
return await ajaxRequest('/connect/token', 'POST', data, "/", baseURL)
}
@Action
public async LoginByCode(codeInfo: {
code: string
redirect_uri: string
}) {
var code = codeInfo.code;
var redirect_uri = codeInfo.redirect_uri;
var data = null;
var baseUrl = process.env.VUE_APP_BASE_IDENTITY_SERVER;
await Login({
grant_type: 'authorization_code',
code: code,
client_id: process.env.VUE_APP_CLIENT_ID,
redirect_uri: redirect_uri
}, baseUrl)
.then(async (res) => {
data = res;
setToken(data.access_token);
this.SET_TOKEN(data.access_token);
return data
})
return data
}
获取Token后将其保存到vuex或Cookies中
创建回调页面
回调页面是在登录成功后，从回调到登录完成的过渡页面。
创建continue/index.vue，简单的显示登录成功的提示，常用的提示有“登录成功，正在为您继续”，“登录成功，正在为您跳转”等友好提示
<template>
<div class="login-container">
<el-result
icon="success"
title="登录成功"
subTitle="正在继续，请稍候.."
></el-result>
</div>
</template>
在登录成功后，会跳转到continue页面，回调地址会携带授权码，然后调用认证服务器的connect/token接口，获取token
创建onRouteChange函数，在此解析页面地址中的参数
export default class extends BaseVue {
redirect?: string;
otherQuery: Dictionary<string> = {};
@Watch("$route", { immediate: true })
private async onRouteChange(route: Route) {
var loco = window.location;
var appRootUrl = `${loco.protocol}//${loco.host}`;
var query = route.query as Dictionary<string>;
if (query) {
this.redirect = query.redirect;
this.otherQuery = this.getOtherQuery(query);
if (this.otherQuery.code) {
await UserModule.LoginByCode({
code: this.otherQuery.code,
redirect_uri: appRootUrl + "/continue",
}).then(async (re) => {
GetCurrentUserInfo(baseUrl)
.then((re) => {
var result = re as any;
this.afterLoginSuccess(result);
})
.catch((err) => {
console.warn(err);
});
});
}
}
}
成功后将跳转到首页或者redirect指定的页面
async afterLoginSuccess(userinfo) {
this.$router
.push({
// path: this.redirect || "/",
path: "/",
query: this.otherQuery,
})
.catch((err) => {
console.warn(err);
});
}
创建退出登录
只需要清除vuex或Cookies中的token即可，可以调用vue-oidc-client的signOut，但只是跳转到配置的登出地址，不会清除token（前提是redirectAfterSignout为true，并设置了post_logout_redirect_uri）
