好吧，我正在尝试将一些数据发布到某个站点以便 g，但是 javascript 似乎不太喜欢我:(。要执行我的请求：

  var xmlhttp;
    if (window.XMLHttpRequest)
    xmlhttp=new XMLHttpRequest();
    else
    xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
    xmlhttp.open("POST","http://(removed)/forums/en/shoutbox_comet.php",true);
    xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded; charset=utf-8");
    xmlhttp.setRequestHeader("X-Request","JSON");
    xmlhttp.setRequestHeader("Cookie",document.cookie); 
    xmlhttp.onreadystatechange=function(){
    if (xmlhttp.readyState==4)
    alert(xmlhttp.responseText);
    }
    var channels = ['english_486', 'english_0', 'english_459','english_293','english_1310','english_292','english_459','english_293','english_970'];
    var channel = channels[Math.floor(Math.random() * channels.length)];
    var data = "channel="+channel+"&action=publish&type=message&data=HelloWorld";
    xmlhttp.send(data);

发送这个：

OPTIONS http://(removed)/forums/en/shoutbox_comet.php HTTP/1.1

我怎样才能解决这个问题？我希望它发送：

您正在向其他域发出请求。这是浏览器的安全问题。输入CORS。浏览器在 POST 之前发送一个 OPTIONS 请求（有时称为“预检”请求），以确定服务器是否可以响应它。

您必须确保您的服务器正确响应这些请求。
