摘要：
1.添加Nuget包。2.启动时配置[两种模式可以存储在Redis的内存中]//配置服务。AddOptions（）需要从appsettings加载。json//在内存服务中存储IP计数器。AddMemoryCache（）//或存储在Redis//服务中。AddDistributedRedisCache（选项=˃｛//o
1.添加Nuget程序包
2.在start up中进行配置【有两种模式可选 存储在redis中会哦这内存中】
// 需要从appsettings.json中加载配置 services.AddOptions(); // 存储IP计数器在内存中 services.AddMemoryCache(); //或者存储在redis中
//services.AddDistributedRedisCache(options =>{
//options.Configuration = "119.45.138.19:6379,password=123456,connectTimeout=5000,syncTimeout=10000";
//options.InstanceName = "WebRatelimit";
//});
services.Configure<IpRateLimitOptions>(Configuration.GetSection("RateLimitingConfig")); services.AddSingleton<IIpPolicyStore, MemoryCacheIpPolicyStore>(); services.AddSingleton<IRateLimitCounterStore, MemoryCacheRateLimitCounterStore>(); services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>(); services.AddSingleton<IRateLimitConfiguration, RateLimitConfiguration>();
3.在appsetting.json中配置相关参数
"RateLimitingConfig": { //false则全局将应用限制，并且仅应用具有作为端点的规则* 。 true则限制将应用于每个端点 "EnableEndpointRateLimiting": true, //false则拒绝的API调用不会添加到调用次数计数器上 "StackBlockedRequests": false, //获取用户端的真实IP "RealIpHeader": "X-Real-IP", "ClientIdHeader": "X-ClientId", "HttpStatusCode": 200, "QuotaExceededResponse": { "Content": "{{"code":429,"msg":"Visit too frequently, please try again later","data":null}}", "ContentType": "application/json", "StatusCode": 200 }, //ip白名单 "IpWhitelist": [ "139.159.187.209" ], "EndpointWhitelist": [], "ClientWhitelist": [], "GeneralRules": [ { "Endpoint": "*", "Period": "60s", "Limit": 0 } ] }
4.启用配置
//位置放在控制器前面 app.UseIpRateLimiting();
