英文:
cannot use func literal (type func(string, string, echo.Context) bool) as type middleware.BasicAuthValidator in argument to middleware.BasicAuth
问题
我想在使用Echo框架的Golang中应用基本身份验证。我遇到了以下错误：
"# command-line-arguments
.\main.go:44:29: 无法将函数文字（类型
func(string, string, echo.Context) bool）用作middleware.BasicAuthValidator类型的参数
middleware.BasicAuth"
我的代码如下：
package main
import (
"github.com/labstack/echo/v4"
"github.com/labstack/echo/v4/middleware"
"net/http"
)
// 主函数
func main(){
e := echo.New()
g := e.Group("/home")
g.Use(middleware.BasicAuth(func (username, password string, c echo.Context) bool {
if(username=="iamsns" && password=="Iamsns355@"){
return true
} else {
return false
}
}))
g.POST("/login", getHome)
e.Start(":8008")
}
英文:
I want to apply Basic authentication in golang using echo framework. I have following error :

g.Use(middleware.BasicAuth(func (username, password string, c echo.Context) bool {

return true
} else {
return false
}
}))
g.POST("/login", getHome)
e.Start(":8008")
}

根据文档，middleware.BasicAuthValidator 的定义是 func(string, string, echo.Context) (bool, error) 而不是 func(string, string, echo.Context) bool。你需要修改函数签名，使其也返回一个 error。
英文:
According to the docs middleware.BasicAuthValidator is defined as func(string, string, echo.Context) (bool, error) not func(string, string, echo.Context) bool. You need to change the signature to also return an error.
