All output test files in addons/sourcemod/data/curl_test
Test #1 Get cURL version & supported protocols
Test #2 Get a web page
Test #3 Get ca-bundle.crt for #4
Test #4 Verify a https website using ca-bundle.crt
Test #5 Get a web page body & header content to file

Re: [EXTENSION] cURL

thanks. surely will come in handy here or there.

Re: [EXTENSION] cURL & Hash

on next version, all file handle, httppost handle, curl_slist handle can use CloseHandle() to close

Also, i try make a curl + msn example

Re: [EXTENSION] cURL & Hash

I was going to make a plugin that used Google Translate for various features. This extension will definitely be useful (and I'd prefer this over sockets). Thanks!

If you get it functioning, please share it :wink:

Re: [EXTENSION] cURL & Hash

On your Test #5 you save output to a file using fwrite:

Code:

CURL_DEFAULT_OPT(curl);

test_5_file_body = CreateTestFile("test5_body.txt", "w");

test_5_file_header = CreateTestFile("test5_header.txt", "w");

curl_easy_setopt_handle(curl, CURLOPT_WRITEDATA, test_5_file_body);

curl_easy_setopt_handle(curl, CURLOPT_HEADERDATA, test_5_file_header);

curl_easy_setopt_string(curl, CURLOPT_URL, "http://www.google.co.uk/index.html");

But I would like to change the callback function to something else. Normally when using libcurl it would be something like this:

Code:

curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, mycallback)

Is it possible to do this using your extension? And how would I set up the callback?

My objective would be to fetch the contents of a page into a string.

Great! :)

Re: [EXTENSION] cURL & Hash

This might just help me immensely. However I'm a bit new to Sourcemod scripting. Can somebody explain how I would get data from a URL as follows:

http://makeavoice.com/shoutcast/webs...XXX&refresh=XX

It's to receive the track name from said website.
