大佬教程收集整理的这篇文章主要介绍了在Google App Engine 500错误上，应该是200而不是500，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
requestToken = function() {
var getTokenURI = '/gettoken?userid=' + userid;
var httprequest = makerequest(getTokenURI,truE);
httprequest.onreadystatechange = function() {
if (httprequest.readyState == 4) {
if (httprequest.status == 200) {
openChAnnel(httprequest.responseText);
} else {
alert('ERROR: AJAX request status = ' + httprequest.status);
}
}
}
};
function makerequest(url,asynC) {
var httprequest;
if (window.XMLhttprequest) {
httprequest = new XMLhttprequest();
} else if (window.ActiveXObject) {
// IE
try {
httprequest = new ActiveXObject("Msxml2.XMLhttp");
} catch (E) {
try {
httprequest = new ActiveXObject("Microsoft.XMLhttp");
} catch (E) {
}
}
}
if (!httprequest) {
return false;
}
httprequest.open('POST',url,async);
httprequest.send();
return httprequest;
}
它在localhost上运行非常好&Hellip;但是在Google App
ENGIne上，它的httprequest.status等于500，并进入else语句。为什么？
