From b2d32be14f8d4a383b2fe4803c7cbcc30dec6374 Mon Sep 17 00:00:00 2001 From: Your Name Date: Fri, 3 Apr 2026 09:39:32 +0800 Subject: [PATCH] =?UTF-8?q?fix(P2):=20=E4=BF=AE=E5=A4=8D4=E4=B8=AAP2?= =?UTF-8?q?=E8=BD=BB=E5=BE=AE=E9=97=AE=E9=A2=98?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit P2-01: 通配符scope安全风险 (scope_auth.go) - 添加hasWildcardScope()函数检测通配符scope - 添加logWildcardScopeAccess()函数记录审计日志 - 在RequireScope/RequireAllScopes/RequireAnyScope中间件中调用审计日志 P2-02: isSamePayload比较字段不完整 (audit_service.go) - 添加ActionDetail字段比较 - 添加ResultMessage字段比较 - 添加Extensions字段比较 - 添加compareExtensions()辅助函数 P2-03: regexp.MustCompile可能panic (sanitizer.go) - 添加compileRegex()安全编译函数替代MustCompile - 处理编译错误，避免panic P2-04: StrategyRoundRobin未实现 (router.go) - 添加selectByRoundRobin()方法 - 添加roundRobinCounter原子计数器 - 使用atomic.AddUint64实现线程安全的轮询 P2-05: 错误信息泄露内部细节 - 已在MED-09中处理，跳过 --- gateway/internal/router/router.go | 22 +++++-- .../internal/router/router_roundrobin_test.go | 51 ++++++++++++++++ .../internal/audit/sanitizer/sanitizer.go | 37 +++++++---- .../audit/sanitizer/sanitizer_test.go | 43 ++++++++++++- .../internal/audit/service/audit_service.go | 28 +++++++++ .../audit/service/audit_service_test.go | 61 ++++++++++++++++++- .../internal/iam/middleware/scope_auth.go | 41 +++++++++++++ .../iam/middleware/scope_auth_test.go | 25 ++++++++ 8 files changed, 289 insertions(+), 19 deletions(-) create mode 100644 gateway/internal/router/router_roundrobin_test.go diff --git a/gateway/internal/router/router.go b/gateway/internal/router/router.go index 9a47433..0aa0546 100644 --- a/gateway/internal/router/router.go +++ b/gateway/internal/router/router.go @@ -5,6 +5,7 @@ import ( "math" "math/rand" "sync" + "sync/atomic" "time" "lijiaoqiao/gateway/internal/adapter" @@ -36,10 +37,11 @@ type ProviderHealth struct { // Router 路由器 type Router struct { -
