Question content

I added the PUT /:folder route to create the folder

I need a PUT /:folder/:path/to/final/file to be used when the user posts a new file. So I have the root in the first parameter, but I don't know how to create a route that handles 'n' route segments and read it into a single string

For example call

PUT /cats

A folder named cats will be created. This already works

I need to

PUT /cats/milady/first-year/32312.jpg

Recognize "cats" as the first parameter, which is my user-level folder Then check mylady/firstyear as a nested subfolder and create

if necessary

and 32312.jpg file name

How to use gin to set the route? Place

Solution

I found the answer.

I can create groups so under the group I can use an asterisk for "undefined path level"

superGroup := router.Group("/:folder")
{
        
    // Create a folder
    superGroup.PUT("", createFolder)

    // Save file into folder
    superGroup.PUT("/*full-path", uploadFile)
}

Then I can read full-path and folder

func uploadFile(c *gin.Context) {

    folder:= c.Param("folder")
    fullPath := c.Param("full-path")

    ....

    c.Status(http.StatusOK)
}
