HTTP Request with C

Question:

How can I effortlessly make an HTTP request using C ? I aim to retrieve the contents of a web page (an API) and examine its contents for a '1 or '0' value. Can I also save the retrieved contents into a string variable?

Answer:

To achieve your goal, you can utilize the versatile libcurl library. Its C wrapper, curlpp, provides a convenient interface for C programmers. Alternatively, neon, another powerful C library, supports WebDAV.

curlpp offers a natural fit for C users, with numerous examples available in its source distribution. Here's a code snippet illustrating how to retrieve the content of a URL:

#include <curlpp>
#include <curlpp>

// RAII cleanup

curlpp::Cleanup myCleanup;

// Send request and get a result.
// Use a shortcut to retrieve the contents in a string stream ...

std::ostringstream os;
os <p>By checking the examples directory in curlpp's source distribution, you can discover more complex scenarios and a straightforward minimal example using curlpp.</p></curlpp></curlpp>
