How Can I Make HTTP Requests in C Using Libraries Like curlpp?

Making HTTP Requests in C

When working with web-based applications or APIs, sending HTTP requests for data retrieval and processing is often necessary. In C , achieving this task can be facilitated through various libraries.

One widely used library is curlpp, a C wrapper for libcurl that provides a convenient interface for issuing HTTP requests. To download the contents of a page using curlpp:

#include <curlpp/cURLpp.hpp>
#include <curlpp/Options.hpp>

// RAII cleanup
curlpp::Cleanup myCleanup;

// Get request result as string stream
std::ostringstream os;
os << curlpp::options::Url(std::string("http://example.com"));

The os object will contain the contents of the page, which you can then check for the presence of specific strings (e.g., "1" or "0").

Alternative Libraries

• cpp-netlib: A comprehensive HTTP client and server library with advanced features.
