How to create a authentication model to restful API using golang gin?
问题
我希望为我的RESTful API创建一个身份验证模型。希望使用API令牌，并且我在Web服务中使用MVC，我创建了一个名为auth.go的控制器，代码如下：
package controllers
import (
"github.com/gin-gonic/gin"
"os"
)
type AdsControllerAuth struct {
}
func (ac *AdsControllerAuth) TokenAuthMiddleware() gin.HandlerFunc {
return func(c *gin.Context) {
token := c.Request.FormValue("api_token")
if token == "" {
respondWithError(401, "API token required", c)
return
}
if token != os.Getenv("API_TOKEN") {
respondWithError(401, "Invalid API token", c)
return
}
c.Next()
}
}
func respondWithError(code int, message string, c *gin.Context) {
resp := map[string]string{"error": message}
c.JSON(code, resp)
//c.Abort(code)
}
目前它还不能正常工作，有人可以帮忙解决这个问题吗？或者有没有可以参考的示例？

I hope to create a authentication model to my restful API. Hope to use API token and I'm using MVC in web service and I created a auth.go controller like this.
package controllers
import (
"github.com/gin-gonic/gin"
"os"
//"github.com/jinzhu/gorm"
)
type AdsControllerAuth struct {
}
func (ac *AdsControllerAuth)TokenAuthMiddleware gin.HandlerFunc {
return func(c *gin.Context) {
token := c.Request.FormValue("api_token")
if token == "" {
respondWithError(401, "API token required", c)
return
}
if token != os.Getenv("API_TOKEN") {
respondWithError(401, "Invalid API token", c)
return
}
c.Next()
}
}
func respondWithError(code int,message string,c *gin.Context) {
resp := map[string]string{"error": message}
c.JSON(code, resp)
//c.Abort(code)
}
It doesn't working for now can some one help do this or is there are any examples to refer?

我自己编写了一个中间件来检查令牌，代码如下：
package main
import (
"github.com/gin-gonic/gin"
)
// JWTAuthMiddleware 中间件
func JWTAuthMiddleware() gin.HandlerFunc {
return func(c *gin.Context) {
validateToken(c)
c.Next()
}
}
func validateToken(c *gin.Context) {
token := c.Request.Header.Get("X-Auth-Token")
if token == "" {
c.AbortWithStatus(401)
} else if checkToken(token) {
c.Next()
} else {
c.AbortWithStatus(401)
}
}
在这个示例中，我使用了 Header 而不是 FormValue。
可以尝试使用 Chrome DHC 扩展来进行测试：https://chrome.google.com/webstore/detail/dhc-rest-client/aejoelaoggembcahagimdiliamlcdmfm
英文:
I made my own middleware to check token like below:
package main
import (
"github.com/gin-gonic/gin"
)
//JWTAuthMiddleware middleware
func JWTAuthMiddleware() gin.HandlerFunc {
return func(c *gin.Context) {
validateToken(c)
c.Next()
}
}
func validateToken(c *gin.Context) {
token := c.Request.Header.Get("X-Auth-Token")
if token == "" {
c.AbortWithStatus(401)
} else if checkToken(token) {
c.Next()
} else {
c.AbortWithStatus(401)
}
}
In the example, I'm using Header instead of FormValue.
