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