基本字符串拼接错误

你的意思是打印结果里没有原生字符串内容吗？

没看出有啥问题

``` appid := env1.Get("APPID") fmt.Printf("type of appid is %T, len of appid is %d\n", appid, len(appid)) secret := env1.Get("SECRET") fmt.Printf("type of secret is %T, len of secret is %d\n", secret, len(secret)) url := `https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=`+appid+`&secret=`+secret fmt.Println(url) ```
