.net7 htt2.0 htt3.0

服务器端

代码配置

 var builder = WebApplication.CreateBuilder(args);

            builder.WebHost.ConfigureKestrel((context, options) =>
            {
                options.ListenAnyIP(44319, listenOptions =>
                {
　　　　　　　　　　　　// 服务器端支持 http2
                    listenOptions.Protocols = HttpProtocols.Http1AndHttp2;
                    listenOptions.UseHttps();
                });
            });

或者在配置文件配置

"Kestrel": {
    "EndpointDefaults": {
      "Protocols": "Http1AndHttp2"
    }
  }

客户端

 services
            .AddHttpClient(Options.DefaultName)
            .ConfigureHttpClient((httpClient) =>
            {
                httpClient.DefaultRequestVersion = HttpVersion.Version20;
                httpClient.DefaultVersionPolicy = HttpVersionPolicy.RequestVersionOrLower;
            });

注入 IHttpClientFactory httpClientFactory

通过 HttpClient myHttpClient  =  httpClientFactory.CreateClient(); 

或者通过以下方式直接new

        private static async Task Main(string[] args)
        {
　　　　　　　// 设置请求 策略和请求 http协议版本　
            HttpClient myHttpClient = new HttpClient
            {
                DefaultRequestVersion = HttpVersion.Version20,
                DefaultVersionPolicy = HttpVersionPolicy.RequestVersionOrLower
            };
            string requestUrl = "https://localhost:44319/api/abp/a/zzz";
            try
            {
                Console.WriteLine($"GET {requestUrl}.");
                HttpResponseMessage response = await myHttpClient.GetAsync(requestUrl);
                response.EnsureSuccessStatusCode();
                Console.WriteLine($"Response HttpVersion: {response.Version}");
                string responseBody = await response.Content.ReadAsStringAsync();
                Console.WriteLine($"Response Body Length is: {responseBody.Length}");
                Console.WriteLine($"------------Response Body------------");
                Console.WriteLine(responseBody);
                Console.WriteLine($"------------End of Response Body------------");
            }
            catch (HttpRequestException e)
            {
                Console.WriteLine($"HttpRequestException : {e.Message}");
            }
            Console.WriteLine($"Press Enter to exit....");
            Console.ReadLine();



            Console.WriteLine("Hello, World!");
        }

 

注意一定 服务器端 一定要启用 https 协议 如果是 http协议 会遇到各种莫名其妙的问题

http3 跟http2的配置一样 待验证 

我这里目前是win10系统好像不支持 http3.0 根据官方描述 目前至少需要win11 才支持 待验证

我目前本机配置了请求协议最高是只支持 http2.0的
