How do you make a HTTP request with C++?

Question

Is there any way to easily make a HTTP request with C++? Specifically, I want to download the contents of a page (an API) and check the contents to see if it contains a 1 o

Answer 1

The HTTP protocol is very simple, so it is very simple to write a HTTP client. Here is one

https://github.com/pedro-vicente/lib_netsockets

It uses HTTP GET to retrieve a file from a web server, both server and file are command line parameters. The remote file is saved to a local copy.

check http.cc https://github.com/pedro-vicente/lib_netsockets/blob/master/src/http.cc

int http_client_t::get(const char *path_remote_file)
{
  char buf_request[1024];

  //construct request message using class input parameters
  sprintf(buf_request, "GET %s HTTP/1.1\r\nHost: %s\r\nConnection: close\r\n\r\n", path_remote_file, m_server_ip.c_str());

  //send request, using built in tcp_client_t socket
  if (this->write_all(buf_request, (int)strlen(buf_request)) < 0)
  {
    return -1;
  }
