上一篇我们讨论了客户端为SPA在IdentityServer4中的授权码流程，本篇继续讨论MVC应用中的IdentityServer4授权码流程。

1.查看授权码流程

与上篇类似，只是这次的客户端换成MVC应用，其余步骤与方法都一样，不赘述，参考【One by One系列】IdentityServer4（六）授权码流程原理之SPA

抓包截图如下

2.详解IdentityServer4授权码流程（MVC）

2.1 请求IdentityServer4的配置端点-获取各项配置

请求

GET /.well-known/openid-configuration HTTP/1.1
Host: localhost:5001
User-Agent: Microsoft ASP.NET Core OpenIdConnect handler
Request-Id: |d8ea1673-480ea8a77b20fcf1.

响应

2.2 请求IdentityServer4-密钥端点

请求

GET /.well-known/openid-configuration/jwks HTTP/1.1
Host: localhost:5001
User-Agent: Microsoft ASP.NET Core OpenIdConnect handler
Request-Id: |d8ea1673-480ea8a77b20fcf1.

响应

HTTP/1.1 200 OK
Server: Kestrel
{"keys":[{"kty":"RSA","use":"sig","kid":"768AC10B4A3728E20644058B6EDF5051","e":"AQAB","n":"p8rr99FmiZSoeCzEdThzdfX-XTPCRTXW43PftBuHEPS3CcUM2aRnVpthzyXoaxLb9tKCqOplnCRmIlVorRe1UG_MqrhOgRhD-jCftOyBtAgLg992Oh2i2_E-F62fsmcrvkwd6e31DS2QYAIKADYamkAlWjaBKVpqHYHEe40kHMTzgwg7-pqmQQUUViBlCOm19NC4szHfEJkIAa4MeO2S3Vmvc6vVniwggYshkWCIZDNHq3A5KaE0_z8-5RiM_ci37YqoVvfInx9hxnCzRHHsNoQJQldomQVe9kVXepHJPXfpNWa04RJr72ySAJIQSwNw9ZIjKyENjSLnH_RxYQ6fXQ","alg":"RS256"}]}

这两步由Microsoft.AspNetCore.Authentication.OpenIdConnect内部请求

并在load时自动触发submit

window.addEventListener('load', function(){document.forms[0].submit();});

提交至http://localhost:6002/signin-oidc，此时code会被存入mvc客户端后台,这里细节，需要研究过源码才能解答！多半是因为中间件AddOpenIdConnect注册了一个端点！

3.补充

在述2.5小节之后，如果IdentityServer4**没有配置用户选择选项，或者RequireConsent=false,**代码如下

new Client
{
    ClientId="mvc",
    ClientSecrets={ new Secret("secret-mvc".Sha256())},
    AllowedGrantTypes = GrantTypes.Code,
    
    //// 需要用户同意授权，默认为false
    //RequireConsent=true,

    // where to redirect to after login
    RedirectUris = { "http://localhost:6002/signin-oidc" },

    // where to redirect to after logout
    PostLogoutRedirectUris = { "http://localhost:6002/signout-callback-oidc" },

    AllowedScopes = new List<string>
    {
        "api1",
        IdentityServerConstants.StandardScopes.OpenId,
        IdentityServerConstants.StandardScopes.Profile
    }
},

就会直接到authorize回调，返回授权码，请知晓。
