在单元测试中使用httpcontext

using System.Net.Http;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc.Testing;
using Xunit;

public class MyAppTests : IClassFixture<WebApplicationFactory<MyApp.Startup>>
{
    private readonly WebApplicationFactory<MyApp.Startup> _factory;

    public MyAppTests(WebApplicationFactory<MyApp.Startup> factory)
    {
        _factory = factory;
    }

    [Fact]
    public async Task MyController_Get_ReturnsOk()
    {
        // Arrange
        var client = _factory.CreateClient();
        var request = new HttpRequestMessage(HttpMethod.Get, "/mycontroller");
        request.Headers.Add("X-Test-Header", "TestValue");

        // Act
        var response = await client.SendAsync(request);

        // Assert
        response.EnsureSuccessStatusCode();
        var content = await response.Content.ReadAsStringAsync();
        Assert.Equal("MyController", content);
    }
}
