实验环境配置+HOST文件配置如下:+ 127.0.0.1 app.com+ 127.0.0.1 sso.com
IIS配置如下:+ 应用程序池采用.Net Framework 4.0+ 注释IIS绑定的域名,两个完全不同的域名。+ app.com网站配置:+ sso.com网站配置:
实验环境配置
HOST文件配置如下:
127.0.0.1 app.com
127.0.0.1 sso.com
IIS配置如下:
应用程序池采用.Net Framework 4.0
注意IIS绑定的域名,两个完全不同域的域名。
app.com网站配置如下:
sso.com网站配置如下:
memcached缓存:
数据库配置:
数据库采用EntityFramework 6.0.0,首次运行会自动创建相应的数据库和表结构。
授权验证过程演示:
在浏览器地址栏中访问:app.com,如果用户还未登陆则网站会自动重定向至:sso.com/passport,同时通过QueryString传参数的方式将对应的AppKey应用标识传递过来,运行截图如下:
URL地址:sso.com/passport?appkey=670b14728ad9902aecba32e22fa4f6bd&username=
输入正确的登陆账号和密码后,点击登陆按钮系统自动301重定向至应用会掉首页,毁掉成功后如下所示:
由于在不同的域下进行SSO授权登陆,所以采用QueryString方式返回授权标识。同域网站下可采用Cookie方式。由于301重定向请求是由浏览器发送的,所以在如果授权标识放入Handers中的话,浏览器重定向的时候会丢失。重定向成功后,程序自动将授权标识写入到Cookie中,点击其他页面地址时,URL地址栏中将不再会看到授权标示信息。Cookie设置如下:
登陆成功后的后续授权验证(访问其他需要授权访问的页面):
校验地址:sso.com/api/passport?sessionkey=xxxxxx&remark=xxxxxx
返回结果:true,false
客户端可以根据实际业务情况,选择提示用户授权已丢失,需要重新获得授权。默认自动重定向至SSO登陆页面,即:sso.com/passport?appkey=670b14728ad9902aecba32e22fa4f6bd&username=seo@ljja.cn 同时登陆页面邮箱地址文本框会自定补全用户的登陆账号,用户只需输入登陆密码即可,授权成功后会话有效期自动延长一年时间。
