Re: How can use JSL to download this special linked network file?

lwx228 · Feb 5, 2021 06:13 AM

I have tried this link and it does not open in a browser, but using a download tool like IDM It can download a PDF file.

https://pdfssj.sslibrary.com/download/getFile?fileMark=96236406&userMark=&pages=124&time=16125232462...
Can links like this be downloaded with JSL?Thanks Experts!

Analysis of the link

The link appears to be bad or stale. When I curl the link on Linux, I see a 500 error

<!doctype html><html lang="en"><head><title>HTTP Status 500 – Internal Server Error</title><sty ...

Perhaps the server is caching something for you for a limited time, allowing you to ask about it (subsequent pages?) for a few minutes after the initial query before clearing the cached result.

Try this. For me it produces the error message.

parms = [
	"fileMark"=>"96236406",
	"userMark"=>"",
	"pages"=>"124",
	"time"=>"1612704256175",
	"enc"=>"8fe943ac652a572c9f2a5b8df1daa14a",
	"code"=>"109366b792dd692fc19055fc8bc734f4&",
	"cpage"=>"45"
];

s = New HTTP Request(
	URL(
		"https://pdfssj.sslibrary.com/download/getFile"
	),
	form(fields(parms)),
	Method( "GET" ), 

);

result = s << Send;
show(result);
show(s<<GetResponseHeaders);
show(s<<GetWarningHeaders);
show(s<<GetStatusMessage);
show(s<<headers);


//showproperties(s);

result = "<!doctype html><html lang=\!"en\!"><head><title>HTTP Status 500 – Internal Server Error</title><style type=\!"text ...

There may be credential/password/authentication issues, or something else. The server's message means the server was unhappy about the request.

Sometimes the server delivers a better-than-blank-page response:

The problem has been solved:

Open the site through a piece of software called "Selenium" and download the PDF through the script.

Thanks Experts!

Okay, I'll give up the attempt.
I used IDM to get the first PDF download address, analyzed it and completed the rest of the PDF with JSL.Then use IDM to bulk download.
It would be much faster if JSL downloaded it directly.
