【问题描述】:
我正在尝试连接到托管在这样的 url 上的 Redis 服务器。
redis://h:asdfqwer1234asdf@ec2-111-1-1-1.compute-1.amazonaws.com:38799
我尝试使用 2 个库,但没有一个能够连接到服务器。我用过redix.v3 和go-redis。
redix.v3 使用上述类似 URL 时出现恐慌错误。
在go-redis 上,我收到一个错误,提示网址中有太多冒号,我尝试使用此网址
[redis://h:asdfqwer1234asdf@ec2-111-1-1-1.compute-1.amazonaws.com]:38799 在一些帖子中被建议。
仍然没有运气。有没有人成功连接到 Redis 服务器?
redix.v3 的代码和错误
func main() {
fmt.Println("running")
client, err := radix.NewPool("tcp", "redis://h:asdfqwer1234asdf@ec2-111-1-1-1.compute-1.amazonaws.com:38799", 10)
if err != nil {
// handle error
}
var fooVal string
err = client.Do(radix.Cmd(&fooVal, "SET", "foo", "hello"))
fmt.Println(err, fooVal)
}
错误:

请显示代码,有错误。
