使用 Identitity4 和 OidcClient 的授权代码流的网络标准示例

Question

是否有任何Netstandard 2.0示例用于使用Identitity4和OidcClient的授权代码流？ 就像系统浏览器一样，它只在.net核心中

Answer 1

在这里，我第一次尝试仅使用.net stanard 2.0类：

using IdentityModel.OidcClient.Browser;
using System;
using System.Diagnostics;
using System.Linq;
using System.Net;
using System.Runtime.InteropServices;
using System.Threading;
using System.Threading.Tasks;
namespace IVT.OAuth.Client
{
public class SystemBrowser : IBrowser
{
private readonly string sRedirect;
public SystemBrowser(string sRedirect)
{
this.sRedirect = sRedirect;
}
public async Task<BrowserResult> InvokeAsync(BrowserOptions options, CancellationToken cancellationToken)
{
using (var oListener = new HttpListener())
{
using (var process = OpenBrowser(options.StartUrl))
{
BrowserResult result = null;
oListener.Prefixes.Add(sRedirect);
try
{
var CodeResult = await ReceiveCode(oListener);
if (String.IsNullOrWhiteSpace(CodeResult.Item1))
{
result = new BrowserResult { ResultType = BrowserResultType.UnknownError, Error = "Empty response." };
}
else
{
SendResponse(CodeResult.Item2.Response, "<h1>You can now return to the application.</h1>");
Thread.Sleep(1000);
result = new BrowserResult { Response = CodeResult.Item1, ResultType = BrowserResultType.Success };
}
}
catch (TaskCanceledException ex)
{
result = new BrowserResult { ResultType = BrowserResultType.Timeout, Error = ex.Message };
}
catch (Exception ex)
{
result = new BrowserResult { ResultType = BrowserResultType.UnknownError, Error = ex.Message };
}
//process.CloseMainWindow();                    
//process.Close();
return result;
}
}
}
private async Task<Tuple<string, HttpListenerContext>> ReceiveCode(HttpListener oListener)
{
string sCode = string.Empty;
HttpListenerContext oContext = null;
if (!oListener.IsListening)
oListener.Start();
try
{
oContext = await oListener.GetContextAsync();
if (oContext.Request.QueryString.AllKeys.Contains("error"))
{
var sErrorMessage = oContext.Request.QueryString["error"] + Environment.NewLine +
oContext.Request.QueryString["error_description"];
}
else
{
sCode = oContext.Request.Url.Query;
}
}
catch (Exception oException)
{
}
return new Tuple<string, HttpListenerContext>(sCode, oContext);
}
private void SendResponse(HttpListenerResponse response, string responseString)
{        
byte[] buffer = System.Text.Encoding.UTF8.GetBytes(responseString);
// Get a response stream and write the response to it.
response.ContentLength64 = buffer.Length;
System.IO.Stream output = response.OutputStream;
output.Write(buffer, 0, buffer.Length);
response.StatusCode = 200;
response.ContentType = "text/html";
// You must close the output stream.
output.Close();
}
public static Process OpenBrowser(string url)
{
try
{
return Process.Start(new ProcessStartInfo(url));
}
catch
{
// hack because of this: https://github.com/dotnet/corefx/issues/10361
if (RuntimeInformation.IsOSPlatform(OSPlatform.Windows))
{
url = url.Replace("&", "^&");
return Process.Start(new ProcessStartInfo("cmd", $"/c start {url}") { CreateNoWindow = true });
}
else
{
throw;
}
}
}
}
}
