如何使用golang从Firebase获取

Database structure I want to retrive all the data stored in this database using golang

{
 "-KaMY9JKmgyRWVApfcXW" : {
          "EmailId" : "aaa@gmail.com",
          "FirstName" : "abc",
          "LastName" : "xyz",
          "UserType" : "user"
      }
 }

    v := map[string]YourStruct{}
    err := dB.Child("YourChild").Value(&v)
    if err != nil {
      log.Fatal(err)
    }
    fmt.Println("%s
", v)

Where YourStruct{} is the struct which you use for fetching values. YourChild is the child name of your above code.
