package main

import (
    "fmt"
    "github.com/gin-gonic/gin"
)

func main() {
    r := gin.Default()
    // 设置全局跨域访问
    r.Use(CrosHandler())
    err :=r.Run(":8887")
    if err!=nil{
        fmt.Println("error")
    }
}

func CrosHandler() gin.HandlerFunc {
    return func(context *gin.Context) {
        context.Writer.Header().Set("Access-Control-Allow-Origin", "*")
        context.Header("Access-Control-Allow-Origin", "*") // 设置允许访问所有域
        context.Header("Access-Control-Allow-Methods", "POST, GET, OPTIONS, PUT, DELETE,UPDATE")
        context.Header("Access-Control-Allow-Headers", "Authorization, Content-Length, X-CSRF-Token, Token,session,X_Requested_With,Accept, Origin, Host, Connection, Accept-Encoding, Accept-Language,DNT, X-CustomHeader, Keep-Alive, User-Agent, X-Requested-With, If-Modified-Since, Cache-Control, Content-Type, Pragma,token,openid,opentoken")
