// 注入内存缓存服务
builder.Services.AddMemoryCache();
//加载ClientRateLimiting配置文件
builder.Services.ConfigureClientRateLimitOptions(builder.Configuration.GetSection(ClientRateLimiting));
//加载ClientRateLimitPolicies配置文件
builder.Services.ConfigureClientRateLimitPolicies(builder.Configuration.GetSection(ClientRateLimitPolicies));// 注入限流内存缓存服务
builder.Services.AddInMemoryRateLimiting();
// 注入限流配置文件服务
builder.Services.AddSingletonIRateLimitConfiguration, RateLimitConfiguration();var app builder.Build();//启用ClientRateLimitPolicies
var clientPolicyStore app.Services.GetRequiredServiceIClientPolicyStore();
await clientPolicyStore.SeedAsync();
//使用Client限流中间件
app.UseClientRateLimiting();app.MapGet(/test00, ()
{return get test00 ok;
});app.MapGet(/test01, ()
{return get test01 ok;
});
app.MapGet(/test02, ()
{return get test02 ok;
});
app.MapPost(/test02, ()
{return post test02 ok;
});app.Run();appsetings.json{Logging: {LogLevel: {Default: Information,Microsoft.AspNetCore: Warning}},AllowedHosts: *,ClientRateLimiting: {EnableEndpointRateLimiting: false,StackBlockedRequests: false,ClientIdHeader: X-ClientId,HttpStatusCode: 429,EndpointWhitelist: [ get:/test00, *:/test01 ],ClientWhitelist: [ dev-id-1, dev-id-2 ],GeneralRules: [{Endpoint: *,Period: 5s,Limit: 2},{Endpoint: *,Period: 10s,Limit: 3} ]},ClientRateLimitPolicies: {ClientRules: [{ClientId: client-id-1,Rules: [{Endpoint: *,Period: 5s,Limit: 1},{Endpoint: *,Period: 15m,Limit: 200}]},{ClientId: client-id-2,Rules: [{Endpoint: *,Period: 1s,Limit: 5},{Endpoint: *,Period: 15m,Limit: 150},{Endpoint: *,Period: 12h,Limit: 500}]}]}
}配置说明EnableEndpointRateLimiting为false全部请求总次数超过阈值即限流EnableEndpointRateLimiting为true时各个请求单次超过阈值即限流StackBlockedRequests为false时如果前5s请求了2个成功1个失败那第6s后还可以请求一个成功如果这StackBlockedRequests为true时那第6s的请求是不能成功的也就是带不带拒绝的请求{Endpoint: *,Period: 5s,Limit: 2},{Endpoint: *,Period: 10s,Limit: 3},ClientIdHeader指定可以通过Header键为X-ClientId处理限流黑白名单ClientWhitelist值为dev-id-1dev-id-2指Header里X-ClientId只要是其中的值 就放行EndpointWhitelist不参与限流的终节点HttpStatusCode限流后返回的状态码GeneralRules通用限流规则ClientRateLimitPolicies 配置是专门为了对不同的X-ClientId进行不同的限流配置这样可以有区别的来分配流程而不是一概而论可以说是ClientId的灰名单有限流的访问不但可以通过ClientID限流还可以是客户请示Ip来限流配置雷同。IP限流using AspNetCoreRateLimit;var builder WebApplication.CreateBuilder(args);
