有没有办法通过按下按钮从JS向C++发送http请求？

<button id="sendButton">发送请求</button>

document.getElementById("sendButton").addEventListener("click", sendRequest);

function sendRequest() {
  var xhr = new XMLHttpRequest();
  xhr.open("GET", "http://your-backend-url", true);
  xhr.onreadystatechange = function() {
    if (xhr.readyState === 4 && xhr.status === 200) {
      // 请求成功的处理逻辑
      var response = xhr.responseText;
      // ...
    }
  };
  xhr.send();
}

#include <httplib.h>

void handleRequest(const httplib::Request& req, httplib::Response& res) {
  // 处理请求的逻辑
  // ...
  res.set_content("Hello from C++", "text/plain");
}

int main() {
  httplib::Server server;
  server.Get("/", handleRequest);
  server.listen("localhost", 8080);
  return 0;
}
