第一步： 服务器生成Token

   

package api

import (
	"github.com/astaxie/beego/validation"

/*
 获得一个Token
*/
func GetAuth(c *gin.Context) {
	username := c.Query("username")
	password := c.Query("password")

	valid := validation.Validation{}
	a := models.Auth{Username: username, Password: password}
	ok, _ := valid.Valid(&a)

	data := make(map[string]interface{})
	code := e.INVALID_PARAMS
	if ok {
		isExist := corll.GetUserByNameAndPassword(username, password) //models.CheckAuth(username, password)
		if isExist {
			token, err := util.GenerateToken(username, password)
			if err != nil {
				code = e.ERROR_AUTH_TOKEN
			} else {

		} else {

	} else {

		}
	}

	c.JSON(http.StatusOK, gin.H{
		"code": code,
		"msg":  e.GetMsg(code),
		"data": data,
	})
