使用Golang推送Firebase后如何提取自动生成的唯一ID？

Question

I am using firego to do operations on the firebase. I am unable to retrieve the auto generated unique ID after a successful push. I used the fllowing code:

adminData, err := dB.Child("Admins").Push(m)
    if err != nil {
        log.Println(err)
    }

    log.Println("Unique ID: ", adminData)

and it print:

https://myApp.firebaseio.com/Admins/-KddtEfpE3ys4cj0mYE-/.json

the variable adminData is of type *Firebase

but I need only -KddtEfpE3ys4cj0mYE- as type String How I can do this in Golang using firego?

Answer 1

firego does not expose this information, you can either create an issue to firego repository on github or modify the library yourself.

also there is a dirty way to split by / character and get last but one element.

package main

import (
    "fmt"
    "strings"
)

func main() {
    parts := strings.Split("https://myApp.firebaseio.com/Admins/-KddtEfpE3ys4cj0mYE-/.json", "/")
    fmt.Println(parts[len(parts)-2]) // -KddtEfpE3ys4cj0mYE-
}

Though I would recommend you to open an issue to firego :)
