使Identity Server 4将查询参数传递给登录控制器 [英] Make Identity Server 4 pass a query parameter to the login controller

问题描述

当我去授权控制器时(在Identity Server 4中实现):

When I go to authorize controller(implemented in Identity Server 4):

(*)abc.com/authorize?par1=val1&par2=val2

我被重定向到:

(**)abc.com/login?ReturnUrl=abc.com/abc.com%2Fauthorize%3Fpar1%3Dval1%26par2%3Dval2"

人们可以注意到ReturnUrl等于(*)，但只是经过html编码. 我想将par2值作为第二个参数添加到(**)url示例中:

One can notice that ReturnUrl equals the (*) but just being html encoded. I would like to add par2 value as a second parameter to the (**) url example:

abc.com/login?ReturnUrl=abc.com/abc.com%2Fauthorize%3Fpar1%3Dval1%26par2%3Dval2&par2=val2"

如何配置IdentityServer来实现这一目标?

推荐答案

IdentityServer是经过认证的OpenId Connect协议实现，它将您的(*)请求作为标准

IdentityServer is a certified OpenId Connect protocol implementation, and it handles your (*) request as a standard Authorization request, which has predefined structure.

仅有两个不受规范限制的参数是state，它由客户端使用，应按原样发送回去；以及acr_values，其专门用于向服务器发送其他参数.

The only two parameters with no limitation by the spec are the state which is used by clients and should be sent back with response as it is, and acr_values which is specially aimed for sending additional parameters to the server.

您可以通过以下方式出于您的目的使用acr_values:&acr_values=par2:val2，然后在

You can involve acr_values for your purposes the following way: &acr_values=par2:val2 and then in BuildLoginViewModelAsync(string returnUrl) method of the AccountController you can access them as context?.AcrValues. You can extend LoginViewModel to bring the value to the layout.
