Ran*_*agg 159 uac httplistener windows-7 c#-4.0
我在C#中编写HTTP服务器.
当我尝试执行该功能时,HttpListener.Start()
我得到一个HttpListenerException
说法
"拒绝访问".
当我在Windows 7中以管理模式运行应用程序时,它工作正常.
我可以在没有管理员模式的情况下运行吗 如果有,怎么样?如果不是,如何在开始运行后让应用程序更改为管理模式?
using System;
using System.Net;
namespace ConsoleApplication1
{
class Program
{
private HttpListener httpListener = null;
static void Main(string[] args)
{
Program p = new Program();
p.Server();
}
public void Server()
{
this.httpListener = new HttpListener();
if (httpListener.IsListening)
throw new InvalidOperationException("Server is currently running.");
httpListener.Prefixes.Clear();
httpListener.Prefixes.Add("http://*:4444/");
try
{
httpListener.Start(); //Throws Exception
}
catch (HttpListenerException ex)
{
if (ex.Message.Contains("Access is denied"))
{
return;
}
else
{
throw;
}
}
}
}
}

是的,您可以在非管理员模式下运行HttpListener.您需要做的就是为特定URL授予权限.例如
netsh http add urlacl url=http://+:80/MyUri user=DOMAIN\user

你不能,它必须以提升的特权开始.您可以使用runas
动词重新启动它,这将提示用户切换到管理模式
static void RestartAsAdmin()
{
var startInfo = new ProcessStartInfo("yourApp.exe") { Verb = "runas" };
Process.Start(startInfo);
Environment.Exit(0);
}

编辑:实际上,那不是真的; HttpListener可以在没有提升权限的情况下运行,但您需要为要监听的URL授予权限.有关详细信息,请参阅Darrel Miller的答案.

如果http://localhost:80/
用作前缀,则可以在不需要管理权限的情况下侦听http请求.

语法对我来说是错误的,你必须包括引号:
netsh http add urlacl url="http://+:4200/" user=everyone

否则我收到"参数不正确"

如果您想使用"user = Everyone"标志,您需要将其调整为您的系统语言.在英语中如上所述:
netsh http add urlacl url=http://+:80/ user=Everyone

在德国,它将是:
netsh http add urlacl url=http://+:80/ user=Jeder

作为不需要提升或netsh的替代方法,您也可以使用TcpListener.
以下是此示例的修改摘录:https: //github.com/googlesamples/oauth-apps-for-windows/tree/master/OAuthDesktopApp
// Generates state and PKCE values.
string state = randomDataBase64url(32);
string code_verifier = randomDataBase64url(32);
string code_challenge = base64urlencodeNoPadding(sha256(code_verifier));
const string code_challenge_method = "S256";
// Creates a redirect URI using an available port on the loopback address.
var listener = new TcpListener(IPAddress.Loopback, 0);
listener.Start();
string redirectURI = string.Format("http://{0}:{1}/", IPAddress.Loopback, ((IPEndPoint)listener.LocalEndpoint).Port);
output("redirect URI: " + redirectURI);
// Creates the OAuth 2.0 authorization request.
string authorizationRequest = string.Format("{0}?response_type=code&scope=openid%20profile&redirect_uri={1}&client_id={2}&state={3}&code_challenge={4}&code_challenge_method={5}",
authorizationEndpoint,
System.Uri.EscapeDataString(redirectURI),
clientID,
state,
code_challenge,
code_challenge_method);
// Opens request in the browser.
System.Diagnostics.Process.Start(authorizationRequest);
// Waits for the OAuth authorization response.
var client = await listener.AcceptTcpClientAsync();
// Read response.
var response = ReadString(client);
// Brings this app back to the foreground.
this.Activate();
// Sends an HTTP response to the browser.
WriteStringAsync(client, "<html><head><meta http-equiv='refresh' content='10;url=https://google.com'></head><body>Please close this window and return to the app.</body></html>").ContinueWith(t =>
{
client.Dispose();
listener.Stop();
Console.WriteLine("HTTP server stopped.");
});
// TODO: Check the response here to get the authorization code and verify the code challenge

读写方法是:
private string ReadString(TcpClient client)
{
var readBuffer = new byte[client.ReceiveBufferSize];
string fullServerReply = null;
using (var inStream = new MemoryStream())
{
var stream = client.GetStream();
while (stream.DataAvailable)
{
var numberOfBytesRead = stream.Read(readBuffer, 0, readBuffer.Length);
if (numberOfBytesRead <= 0)
break;
inStream.Write(readBuffer, 0, numberOfBytesRead);
}
fullServerReply = Encoding.UTF8.GetString(inStream.ToArray());
}
return fullServerReply;
}
private Task WriteStringAsync(TcpClient client, string str)
{
return Task.Run(() =>
{
using (var writer = new StreamWriter(client.GetStream(), new UTF8Encoding(false)))
{
writer.Write("HTTP/1.0 200 OK");
writer.Write(Environment.NewLine);
writer.Write("Content-Type: text/html; charset=UTF-8");
writer.Write(Environment.NewLine);
writer.Write("Content-Length: " + str.Length);
writer.Write(Environment.NewLine);
writer.Write(Environment.NewLine);
writer.Write(str);
}
});

httpListener.Prefixes.Add("http://*:4444/");

您使用“*”,因此您以管理员身份执行以下 cmd
netsh http add urlacl url=http://*:4444/ user=username

不用+,必须用*,因为你指定*:4444~。

如果将Application Manifest添加到项目中,则可以以管理员身份启动应用程序.
只需将新项添加到项目中,然后选择"应用程序清单文件".将<requestedExecutionLevel>
元素更改为:
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />

默认情况下,Windows定义以下每个人都可用的前缀: http:// +:80/Temporary_Listen_Addresses /
所以你可以注册你的HttpListener
通道:
Prefixes.Add("http://+:80/Temporary_Listen_Addresses/" + Guid.NewGuid().ToString("D") + "/";
这有时会导致Skype等软件出现问题,默认情况下会尝试使用端口80.
