Ocelot 和 .net 核心的新手。我正在尝试在 Ocelot 网关的 .net core 3.0 微服务中实现缓存。根据 Ocelot 指南 ( https://ocelot.readthedocs.io/en/latest/features/caching.html )
按照第二步，我的 startup.cs 看起来像：
using System.Text;
using Microsoft.AspNetCore.Authentication.JwtBearer;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using Microsoft.IdentityModel.Tokens;
using Ocelot.DependencyInjection;
using Ocelot.Middleware;
namespace MS_APIGateway
{
public class Startup
{
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)
{
services.AddOcelot().AddCacheManager(x => **// Getting error here**
{
x.WithDictionaryHandle();
});
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public async void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseHttpsRedirection();
app.UseRouting();
//JWT
app.UseAuthentication();
//JWT
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
await app.UseOcelot();
}
}
}
编译器在AddCacheManager行抛出错误，错误消息是：
Error CS0411 The type arguments for method 'ServiceCollectionExtensions.AddCacheManager<T>(IServiceCollection, IConfiguration, string, Action<ConfigurationBuilder>)' cannot be inferred from the usage. Try specifying the type arguments explicitly.
请帮忙。谢谢你。
