从香港ecs 调用service/ecs 在accesskey 身份校验总是选择cn-hangzhou 导致超时。报错如下：
Post "https://ecs-cn-hangzhou.aliyuncs.com/?AccessKeyId=xxx&Action=DescribeInstances&Format=JSON&PageSize=100&RegionId=cn-hongkong&Signature=dddxxx&SignatureMethod=HMAC-SHA1&SignatureNonce=08de82467031220486323a2966c470c4&SignatureType=&SignatureVersion=1.0&Timestamp=2021-09-17T08%3A34%3A50Z&Version=2014-05-26": context deadline exceeded (Client.Timeout exceeded while awaiting headers)

我的golang代码如下：

client, err := ecs.NewClientWithAccessKey("cn-hongkong", string(akid), string(aks))
if err != nil {
	// 异常处理
	panic(err)
}
request := ecs.CreateDescribeInstancesRequest()
request.SetReadTimeout(30 * time.Second)
request.SetConnectTimeout(30 * time.Second)
request.Scheme = "https"

request.PageSize = requests.NewInteger(100)

response, err := client.DescribeInstances(request)

alibaba-cloud-sdk-go/sdk/endpoints/ 代码文件mapping_resolver.go 函数GetEndpointFromMap第44行
key := fmt.Sprintf(keyFormatter, strings.ToLower(regionId), strings.ToLower(productId))
这个key返回cn-hongkong::ecs没有问题，但是问题在第46行代码
endpoint := endpointMapping.endpoint[key]
这个endpoint返回ecs-cn-hangzhou.aliyuncs.com

遇到了类似的问题 是使用姿势不对吗？

遇到了类似的问题 是使用姿势不对吗？

你需要选择内网访问也就是走vpc，不过这样子外网机器就无法访问，但是如果在香港的外网机器要通过脚本修改或者查询一些东西又跑回去杭州的endpoint就又经常失败，不知道怎么解决，阿里那边也没有给出具体解决办法

深圳的ecs 走cn-shenzhen 偶尔也会失败

一堆问题貌似阿里都不打算fix了

这个问题是 gfw 的问题。
