如何在ASP.NET核心Web和WebAPI容器之间建立通信

using System.Net.Http;

public class MyWebClass
{
    private readonly HttpClient _httpClient;

    public MyWebClass(HttpClient httpClient)
    {
        _httpClient = httpClient;
    }

    public async Task<string> GetDataFromWebAPI()
    {
        // 发送GET请求到WebAPI的某个接口
        HttpResponseMessage response = await _httpClient.GetAsync("https://api.example.com/data");

        // 确保请求成功
        response.EnsureSuccessStatusCode();

        // 读取响应内容
        string data = await response.Content.ReadAsStringAsync();

        return data;
    }
}

[Route("api/[controller]")]
[ApiController]
public class MyWebApiController : ControllerBase
{
    [HttpGet]
    public ActionResult<string> GetData()
    {
        // 处理请求并返回数据
        string data = "This is the data from WebAPI";

        return data;
    }
}

public void ConfigureServices(IServiceCollection services)
{
    // 注册HttpClient实例
    services.AddHttpClient();

    // 其他配置...
}

public void ConfigureServices(IServiceCollection services)
{
    // 配置HttpClient以指定WebAPI的基地址
    services.AddHttpClient("WebAPI", client =>
    {
        client.BaseAddress = new Uri("https://api.example.com/");
    });

    // 其他配置...
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env, IHttpClientFactory httpClientFactory)
{
    // 其他配置...

    // 使用HttpClientFactory创建HttpClient实例
    HttpClient httpClient = httpClientFactory.CreateClient("WebAPI");

    // 注入HttpClient实例到MyWebClass中
    app.UseEndpoints(endpoints =>
    {
        endpoints.MapGet("/", async context =>
        {
            var myWebClass = new MyWebClass(httpClient);
            string data = await myWebClass.GetDataFromWebAPI();

            await context.Response.WriteAsync(data);
        });
    });
}
