对于进程内托管,传递给SetBasePath
的正确参数是什么?
我们以这种方式设置配置:
private static IConfiguration Configuration { get; } = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("appsettings.json", optional: false)
.Build();
但是,在ASP.NET Core 2.2进程内托管中,Directory.GetCurrentDirectory()
返回C:\Program Files\IIS Express
而不是我的应用程序根目录。
编辑:
我正在Program.Main
中初始化我的配置,以便在example之后读取要传递给Serilog的设置。
答案:
可悲的是,这个问题被标记为重复,因此回答了该问题。
问题是discussed here。在下一次ASP.NET Core更新中,GetCurrentDirectory将提供与进程外托管相同的值。同时,提供以下代码作为解决方法。
using System;
namespace SampleApp
{
internal class CurrentDirectoryHelpers
{
internal const string AspNetCoreModuleDll = "aspnetcorev2_inprocess.dll";
[System.Runtime.InteropServices.DllImport("kernel32.dll")]
private static extern IntPtr GetModuleHandle(string lpModuleName);
[System.Runtime.InteropServices.DllImport(AspNetCoreModuleDll)]
private static extern int http_get_application_properties(ref IISConfigurationData iiConfigData);
[System.Runtime.InteropServices.StructLayout(System.Runtime.InteropServices.LayoutKind.Sequential)]
private struct IISConfigurationData
{
public IntPtr pNativeApplication;
[System.Runtime.InteropServices.MarshalAs(System.Runtime.InteropServices.UnmanagedType.BStr)]
public string pwzFullApplicationPath;
[System.Runtime.InteropServices.MarshalAs(System.Runtime.InteropServices.UnmanagedType.BStr)]
public string pwzVirtualApplicationPath;
public bool fWindowsAuthEnabled;
public bool fBasicAuthEnabled;
public bool fAnonymousAuthEnable;
}
public static void SetCurrentDirectory()
{
try
{
// Check if physical path was provided by ANCM
var sitePhysicalPath = Environment.GetEnvironmentVariable("ASPNETCORE_IIS_PHYSICAL_PATH");
if (string.IsNullOrEmpty(sitePhysicalPath))
{
// Skip if not running ANCM InProcess
if (GetModuleHandle(AspNetCoreModuleDll) == IntPtr.Zero)
{
return;
}
IISConfigurationData configurationData = default(IISConfigurationData);
if (http_get_application_properties(ref configurationData) != 0)
{
return;
}
sitePhysicalPath = configurationData.pwzFullApplicationPath;
}
Environment.CurrentDirectory = sitePhysicalPath;
}
catch
{
// ignore
}
}
}
}
