go echo 允许跨域

这里有个巨坑官方文档没有提及这个需要导入v4版本的中间件

import (
    "net/http"
    "time"

    "github.com/idoubi/goz"
    "github.com/labstack/echo/v4"
    "github.com/labstack/echo/v4/middleware"
)

main function

func main() {
    e := echo.New()
    e.Use(middleware.CORSWithConfig(middleware.CORSConfig{AllowOrigins: []string{"*"}, AllowMethods: []string{echo.GET, echo.HEAD, echo.PUT, echo.PATCH, echo.POST, echo.DELETE}}))
    e.GET("/", func(c echo.Context) error {
        return c.String(http.StatusOK, "Hello, World!")
    })

    e.POST("/textserver", textserver)
    e.Logger.Fatal(e.Start(":1323"))
}
