Today on a server suddenly saw a curl process has been running for 28 days still wood end, a little strange. I also set the timeout time when using curl,--connect-timeout 5.
Curl--connect-timeout 5--data-binary "set=${l_upload_data_encoded}" http://172.88.99.00:8080/xxx.php &>/dev /null supposedly, 5s would have timed out. Think of wget as if the timeout time, there is a phased, such as the request timeout, transmission timeout and so on, so carefully looked at the next Curl Hand album:
When using curl, there are two timeout times: one is the connection timeout and the other is the maximum time allowed for the entire process,--connect-timeout <seconds>
Maximum time in seconds so you allow the connection to the server to take. This only limits the connection phase, once curl has connected this option is of no more use. Also the-m/--max-time option.
If This option is used several times, the last one would be used. This is the specified connection timeout time. If an error occurs, the hint is as follows: Curl: () connect () timed out! -m/--max-time <seconds>
Maximum time in seconds so you allow the whole operation to take. This is useful the for preventing your batch the jobs from hanging for hours, to due slow or links networks down. Also the--connect-timeout option.
If This option is used several times, the last one would be used. This is the maximum allowable time specified. Error prompts such as: Curl: () Operation timed out after the milliseconds with 0 bytes received
You can also use this: Curl-o x.log "http://www.yyyy.com"--speed-time 5--speed-limit 1
It means that the URL content is saved to X.log, and if the transfer speed is less than 1 bytes/sec lasts 5 seconds, the connection terminates.
When using curl, there are two timeout times: one is the connection timeout and the other is the maximum allowable time for data transfer.
The connection timeout is specified with the--connect-timeout parameter, and the maximum allowable time for data transfer is specified with the-m parameter.
For example:
Curl--connect-timeout 10-m "Http://XXXXXXX"
If the connection times out, the error prompts such as:
Curl: () connect () timed out!
When the maximum allowable time for data transfer times out, the error prompts are as follows:
Curl: () Operation timed out after-milliseconds with 0 bytes received
