The network file such as: http://127.0.0.1/cd/xx.pdf
Very slow when the network disconnected or network file server to download the main program will always stuck in there when the interface feign death, how to set up a judgment that make them give up the download to download the next file? Please give idea

Suggestion to download in one thread, thread, sets the timeout time, overtime to exit,
Best, will timeout is associated with the file size, so that more reasonable,

CodePudding user response:

I am in multiple files to download if the thread in turn caused by speed has been waiting for the download is complete so will wait
I am circulating a single file download download into the multithreading a thread end begin to download another file

If a file is slow may have to wait a long time to have a better solution

Sometimes a download Pdf 1 to 2 MB results waiting for an hour or two how to set the timeout in the thread? Continue to pray

CodePudding user response:

They are not said you download thread to set the timeout!

Are you use another thread to monitor your download threads,
I can give you an idea,,,
Existing thread A (download), B (supervisors, supervision of many), the timer (Stopwatch)
1. Be started, a single download, read the value of the timer as the stamp of the downloaders
2. When the callback is invoked, read the latest value of the timer as the stamp of the downloaders
3. The supervisors constantly, using the current value of the timer, to contrast the activities of the individual downloaders stamp
4. If more than the specified time, the inventory for overtime or wrong, and end goal downloaders directly
