在javascript中获取http.post然后发送响应

Question

在 php 中有很多方法可以做到这一点，但我不是服务器端，那么有没有办法在纯 JS 中做到这一点？

Answer 1

Pure JS? Yes, but only on the server (the specifics would depend on which SSJS implementation you use, Express + NodeJS is popular at present).

You can't receive a POST request on the client. The client makes the request. The server makes the response. That is how HTTP works.

Answer 2

<script>
function showHint(str) {
    if (str.length == 0) { 
        document.getElementById("txtHint").innerHTML = "";
        return;
    } else {
        var xmlhttp = new XMLHttpRequest();
        xmlhttp.onreadystatechange = function() {
            if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
                document.getElementById("txtHint").innerHTML = xmlhttp.responseText;
            }
        };
        xmlhttp.open("GET", "gethint.php?q=" + str, true);
        xmlhttp.send();
    }
}
</script>
