如何从服务层获取HttpContext

public class MyService
{
    private readonly IHttpContextAccessor _httpContextAccessor;

    public MyService(IHttpContextAccessor httpContextAccessor)
    {
        _httpContextAccessor = httpContextAccessor;
    }

    public void DoSomething()
    {
        var httpContext = _httpContextAccessor.HttpContext;
        // 使用 httpContext 进行操作
    }
}

public void ConfigureServices(IServiceCollection services)
{
    services.AddHttpContextAccessor();
    // 其他服务配置
}

public class MyService
{
    private readonly IHttpContextFactory _httpContextFactory;

    public MyService(IHttpContextFactory httpContextFactory)
    {
        _httpContextFactory = httpContextFactory;
    }

    public async Task DoSomethingAsync()
    {
        var httpContext = await _httpContextFactory.CreateHttpContextAsync();
        // 使用 httpContext 进行操作
    }
}

public void ConfigureServices(IServiceCollection services)
{
    services.AddHttpContextFactory();
    // 其他服务配置
}

// Startup.cs
public void ConfigureServices(IServiceCollection services)
{
    services.AddHttpContextAccessor();
    services.AddScoped<MyService>();
}

// MyService.cs
public class MyService
{
    private readonly IHttpContextAccessor _httpContextAccessor;

    public MyService(IHttpContextAccessor httpContextAccessor)
    {
        _httpContextAccessor = httpContextAccessor;
    }

    public void DoSomething()
    {
        var httpContext = _httpContextAccessor.HttpContext;
        var request = httpContext.Request;
        var response = httpContext.Response;

        // 示例：记录请求的 URL 和 IP 地址
        var url = request.Host.Value + request.Path + request.QueryString.Value;
        var ipAddress = request.Headers["X-Forwarded-For"] ?? request.Connection.RemoteIpAddress.ToString();

        Console.WriteLine($"Request URL: {url}");
        Console.WriteLine($"Client IP: {ipAddress}");
    }
}
