3rd:VPcURL

The VPcURL package provides Visual Prolog bindings to the cURL library, which is a library for HTTP and FTP.

Provided by Jan de Lint.

Features

• VPcURL functions which are reasonable close to the Curl manual.
• VP multithreading replacing curl_multi
• HTTP and FTP
• zlib compression library (some functions), see the Zlib specs

Separate classes with runnable annotated samples include

• a complex connection with POST, file-upload, POST- and GET-vars, file download all in one go.
• a simple case opening a page (.HTML) on the internet which does not exist
• a simple case downloading an image file from the internet and saving it on disk.
• an FTP upload testcase (please provide your own FTP adres, userid and password).
• an FTP download case
• a 3 step header/redirect example
• a debug mode example

I assume you need VP 7101 for the background cases to run properly.

Please edit testcases.pro, testcase 5 and 6 (numbers 4 and 5), to provide your own FTP parameters. The other testcases are HTTP and can be run out of the box, provided the servers are not down. F5 will randomly pick a background testcase and run it. Once all the testcases do run, you could do some stress-testing by constantly hitting the F5 key.

Here are recommendations: how to incorporate VPcURL in your program
