Go int type convert string, by reflection type comparison

This is a creation in Article, where the information may have evolved or changed.

1. When you spell a string, the following syntax will cause an error:

Mismatched types string and int

Func geterrorjsondata (status int, msg string) string {jsons: = "{\" status\ ":" +status+ ", \" message\ ": \" "+ msg +" \ "}" Retu RN Jsons}

The correct wording is: need to introduce " StrConvThe package

Func geterrorjsondata (status int, msg string) string {jsons: = "{\" status\ ":" + StrConv. Itoa (status) + ", \" message\ ": \" "+ msg +" \ "}" return jsons}

2. Reflection Type Comparison

var user map[string]interface{}

<pre name= "code" class= "HTML" >user["username"] get the parameters in the map

Reflect. TypeOf (user["username"])//Get the type in map

Reflect. TypeOf (user["username"]) ==reflect. string//matches string, success is true, otherwise false
