Golang 全局变量

2018-11-25 02:42:45 catherine

不主张用全局变量,因为容易被污染,但是有些时候,我们想用全局变量,如下:

package main
import "github.com/gin-gonic/gin"
var testValue = 1
func main() {
    r := gin.Default()
    r.GET("/", func(c *gin.Context) {
        testValue += 1
        c.JSON(200, gin.H{
            "message": "Hello World",
        })
    })
    r.GET("/abc", func(c *gin.Context) {
        print(testValue)
        c.JSON(200, gin.H{
            "message": "Hello ABC",
            "testValue": testValue,
        })
    })
    r.Run() // listen and server on 0.0.0.0:8080 by default
}
