Go Range 的坑

go range 的坑

apiV1 = r.Group("/api/v1")
	{
		for _, hConf := range *config.HookConfig {
			apiV1.GET(hConf.Name, v1.HandleHook(&hConf))
		}
  }
  
[GIN-debug] [WARNING] Running in "debug" mode. Switch to "release" mode in production.
 - using env:	export GIN_MODE=release
 - using code:	gin.SetMode(gin.ReleaseMode)

[GIN-debug] GET    /api/v1/docs              --> hook/controller/v1.HandleHook.func1 (4 handlers)
[GIN-debug] GET    /api/v1/web               --> hook/controller/v1.HandleHook.func1 (4 handlers)

然后发现请求 /api/v1/docs 和 /api/v1/web , 都是为同一结果

代码修正

apiV1 = r.Group("/api/v1")
	{
		for _, hConf := range *config.HookConfig {
			conf := hConf
			apiV1.GET(hConf.Name, v1.HandleHook(&conf))
		}
	}

多加了 conf := hConf

原因

根本原因在于for range 会使用同一块内存去接收循环中的值
