<br class="">
Please can someone explain how,using the wreq package, I can download and save a binary file?<br class="">
Say the file is at the end of<br class="">
<a href="http://x.y.z/files/myfile.jpg" rel="noreferrer" target="_blank" class="">http://x.y.z/files/myfile.jpg</a><br class="">
<br class="">
and it is a jpeg and no authentication is needed.<br class="">
<br class="">
I just want to<br class="">
<br class="">
1. Check that the URL is syntactically correct - flag and error if not<br class="">
2. If the URL is syntactically ok then download the file using GET.<br class="">
3. Check that the response code is 200 and if so save the file<br class="">
3a. if the response code is not 200 then delegate to an error handling function or some simple idiomatic way of error handling.<br class="">
<br class="">
<br class="">
Thanks once again.<br class="">
<br class="">
Mike<br class="">
