如何在 linux 服务计划中为我的 API 启用压缩？

Question

我正在将 .net-core 网络 API 部署到 Linux 应用服务计划。我还没有创建 DOCKERFILE。只是构建生产发布和部署。根据生产中的响应 headers，它似乎正在使用 Kestrel 服务器。我在 MS 文档中发现可以在代码中启用压缩。这种方法似乎在本地工作得很好，但是我在生产过程中没有在我的网络 API 调用中看到 Content-Encoding header。

Answer 1

您可以在 startup.cs 文件中添加以下代码。它对我有用。

// Configure Compression level
services.Configure<GzipCompressionProviderOptions>(options => options.Level = CompressionLevel.Fastest);

// Add Response compression services
services.AddResponseCompression(options =>
{
    options.Providers.Add<GzipCompressionProvider>();
    options.EnableForHttps = true;
});

并且你还需要在配置函数中添加app.UseResponseCompression();。

测试结果：

        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            // Configure Compression level
            services.Configure<GzipCompressionProviderOptions>(options => options.Level = CompressionLevel.Fastest);

            // Add Response compression services
            services.AddResponseCompression(options =>
            {
                options.Providers.Add<GzipCompressionProvider>();
                options.EnableForHttps = true;
            });
            services.AddControllers();
            services.AddSwaggerGen(c =>
            {
                c.SwaggerDoc("v1", new OpenApiInfo { Title = "corewebapp_linux", Version = "v1" });
            });
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
                app.UseSwagger();
                app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "corewebapp_linux v1"));
            }
            app.UseResponseCompression();
            app.UseHttpsRedirection();
            app.UseRouting();

            app.UseAuthorization();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllers();
            });
        }
