我也很难找到有关如何仅生成令牌部分的文章。我从未找到自己写的。因此，如果有帮助：
要做的事情是：
- 创建一个新的Web应用程序
- 安装以下NuGet软件包：
Microsoft.OwinMicrosoft.Owin.Host.SystemWebMicrosoft.Owin.Security.OAuthMicrosoft.AspNet.Identity.Owin
- 添加一个OWIN
startup类
然后创建index.js包含以下内容的HTML和JavaScript（）文件：
var loginData = 'grant_type=password&username=test.test@mail.com&password=test123';
var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function () {
if (xmlhttp.readyState === 4 && xmlhttp.status === 200) {
alert(xmlhttp.responseText);
}
}
xmlhttp.open("POST", "/token", true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.send(loginData);
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<script type="text/javascript" src="index.js"></script>
</body>
</html>
OWIN startup类应具有以下内容：
using System;
using System.Security.Claims;
using Microsoft.Owin;
using Microsoft.Owin.Security.OAuth;
using OAuth20;
using Owin;
[assembly: OwinStartup(typeof(Startup))]
namespace OAuth20
{
public class Startup
{
public static OAuthAuthorizationServerOptions OAuthOptions { get; private set; }
public void Configuration(IAppBuilder app)
{
OAuthOptions = new OAuthAuthorizationServerOptions()
{
TokenEndpointPath = new PathString("/token"),
Provider = new OAuthAuthorizationServerProvider()
{
OnValidateClientAuthentication = async (context) =>
{
context.Validated();
},
OnGrantResourceOwnerCredentials = async (context) =>
{
if (context.UserName == "test.test@mail.com" && context.Password == "test123")
{
ClaimsIdentity oAuthIdentity = new ClaimsIdentity(context.Options.AuthenticationType);
context.Validated(oAuthIdentity);
}
}
},
AllowInsecureHttp = true,
AccessTokenExpireTimeSpan = TimeSpan.FromDays(1)
};
app.UseOAuthBearerTokens(OAuthOptions);
}
}
}
运行您的项目。该令牌应显示在弹出窗口中。
