<s>[INST] How to make a HTTP request in C++ code, give me 2 examples using pure C++ and using external library, which is more efficient? [/INST] Making an HTTP request in C++ code can be done either using pure C++ or by using an external library. Using pure C++, you can use the boost library to make an HTTP request, which is a well-known library for C++. Here is an example of how to use the boost library to make an HTTP request:

#include <boost/asio.hpp>
#include <iostream>

using namespace boost::asio;

int main()
{
    io_context io_context;

    ip::tcp::resolver resolver(io_context);
    ip::tcp::resolver::query query("www.example.com", "http");
    ip::tcp::resolver::iterator iter = resolver.resolve(query);

    ip::tcp::socket socket(io_context);
    connect(socket, iter);

    std::string request = "GET / HTTP/1.1\r\nHost: www.example.com\r\n\r\n";
    write(socket, buffer(request));

    boost::asio::streambuf response;
    boost::asio::read_until(socket, response, "\r\n");

    std::cout << &response;

    return 0;
}

Alternatively, you can use an external library such as cURL to make an HTTP request. Here is an example of how to use cURL to make an HTTP request:

#include <curl/curl.h>

int main(void)
{
    CURL *curl;
    CURLcode res;

    curl = curl_easy_init();
    if(curl) {
        curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");

        /* Perform the request, res will get the return code */ 
        res = curl_easy_perform(curl);
        /* Check for errors */ 
        if(res != CURLE_OK)
            fprintf(stderr, "curl_easy_perform() failed: %s\n",
                    curl_easy_strerror(res));

        /* always cleanup */ 
        curl_easy_cleanup(curleasycleanup(curl); 
        }

        return 0; 
}</s>\ <s>[INST] Great, change the examples to do a GET request from https://open-assistant.io/tasks/random [/INST] Making an HTTP request in C++ code can be done either using pure C++ or by using an external library. Here is an example of how to use pure C++ to make a GET request using the boost library:

#include <boost/asio.hpp>
#include <iostream>

using namespace boost::asio;

int main()
{
io_context io_context;
ip::tcp::resolver resolver(io_context);
ip::tcp::resolver::query query("open-assistant.io", "https");
ip::tcp::resolver::iterator iter = resolver.resolve(query);

ip::tcp::socket socket(io_context);
connect(socket, iter);

std::string request = "GET /tasks/random HTTP/1.1\r\nHost: open-assistant.io\r\n\r\n";
write(socket, buffer(request));

boost::asio::streambuf response;
boost::asio::read_until(socket, response, "\r\n");

std::cout << &response;

return 0;
}

And here is an example of how to use an external library, cURL, to make a GET request:

#include <curl/curl.h>

int main(void)
{
CURL *curl;
CURLcode res;
curl = curl_easy_init();
if(curl) {
    curl_easy_setopt(curl, CURLOPT_URL, "https://open-assistant.io/tasks/random");

    /* Perform the request, res will get the return code */ 
    res = curl_easy_perform(curl);
    /* Check for errors */ 
    if(res != CURLE_OK)
        fprintf(stderr, "curl_easy_perform() failed: %s\n",
                curl_easy_strerror(res));

    /* always cleanup */ 
    curl_easy_cleanup(curl);
}

return 0; 
}

In terms of efficiency, it is generally considered that using an external library like cURL is more efficient and convenient than using pure C++, as it abstracts away many of the low-level details and provides a higher-level interface for making HTTP requests.</s>
