Gin错误死机:通配符路由与现有子项冲突
Gin错误死机:通配符路由与现有子项冲突
提问于 2019-12-03 06:19:23
我使用https://github.com/gin-gonic/gin，并尝试实现如下嵌套路由：
// SetupRouter initialize routes and handlers
func SetupRouter() *gin.Engine {
r := gin.Default()
r.GET("/", controllers.Welcome)
r.GET("/resources", controllers.GetResources)
r.GET("/resources/otherroute", controllers.GetOResources)
r.GET("/resources/:id", controllers.GetResourcesByID)
r.GET("/resources/:id/sub-resources", GetSubResources)
r.GET("/resources/:id/sub-resources/:srid", GetSubResourcesByID)
r.GET("/resources/:id/sub-resources/:srid/ssub-resources", GetSSubResources)
r.GET("/resources/:id/sub-resources/:srid/ssub-resources/:ssrid", GetSSubResourcesByID)
// .... etc.
return r
}但是我得到了一些奇怪的错误：
[GIN-debug] GET / --> github.com/badis/so-
gin-nested-routes/controllers.Welcome (3 handlers)
[GIN-debug] GET /resources --> github.com/badis/so-gin-nested-routes/controllers.GetResources (3 handlers)
[GIN-debug] GET /resources/otherroute --> github.com/badis/so-gin-nested-routes/controllers.GetOResources (3 handlers)
[GIN-debug] GET /resources/:id --> github.com/badis/so-gin-nested-routes/controllers.GetResourcesByID (3 handlers)
panic: wildcard route ':id' conflicts with existing children in path '/resources/:id'
goroutine 1 [running]:

/home/badis/go/src/github.com/gin-gonic/gin/tree.go:255 +0x4ea我不能找到一个令人满意的解决方案。

Gin不能区分/resources/otherroute和/resources/:id，因为otherroute可以被解释为:id，因此会有冲突。

试试这个：
// SetupRouter initialize routes and handlers
func SetupRouter() *gin.Engine {
r := gin.Default()
r.GET("/", controllers.Welcome)
r.GET("/resources", controllers.GetResources)
r.GET("/resources/otherroute", controllers.GetOResources)
resources := r.Group("/resources/:rid")
{
resources.GET("", controllers.GetResourcesByID)
resources.GET("otherroute", controllers.GetOResources)
resources.GET("sub-resources", controllers.GetSubResources)
subResources := resources.GET("sub-resources/:srid")
{
subResources.GET("", GetSubResourcesByID)
subResources.GET("/ssub-resources", GetSSubResources)
subResources.GET("/ssub-resources/:ssrid", GetSSubResourcesByID)
}
}
// .... etc.
return r
