How to tell a curl max-time apart from a connect-timeout?
提问by vgm
Example command
示例命令
curl -s -w "%{http_code} %{http_connect}" --connect-timeout 10 --max-time 50
Will return 000 000for both the connect-timeout being reached and the max-time being reached. What is the best way to tell these two errors apart?
将000 000在达到连接超时和达到最大时间时返回。区分这两个错误的最佳方法是什么？
The only difference, as far as I can see, is when the -sflag is removed:
据我所知，唯一的区别是-s标志被移除的时间：
- Connection timeout returns
curl: (28) connect() timed outand - Max timeout returns
curl: (28) Operation timed out
- 连接超时返回
curl: (28) connect() timed out和 - 最大超时返回
curl: (28) Operation timed out

There are two points in your question:
你的问题有两点：
- HTTP CODE
- Distinguish the difference
- 代码
- 区分差异
HTTP CODE
代码
When the order is failed, there will be no http code.Because there is no reponse.You can acquire the http code only when the order is success.
下单失败时，不会有http代码，因为没有响应，只有下单成功才能获取http代码。
Distinguish the difference
区分差异
You can gain the error by the follow order.
您可以通过以下顺序获得错误。
result=`curl --connect-timeout $connectiontimeout --max-time $maxtimeout -s -S -X POST -H 'Content-Type: text/plain' -d "$DATA" "$resturl" 1>&1 2>&1`
if [ "$result" = "curl: (28) connect() timed out" ] ;then
echo "curl: (28) connect() timed out"
fi
Then you can judge the result to distinguish the two error.
然后你可以判断结果来区分这两个错误。
