我正在从跨域调用ajax并获取Error ::
XMLHttpRequest无法加载http:// * ** :8080 / ActiveDirectiveActionRepulsionController.ashx。请求的资源上不存在“Access-Control-Allow-Origin”标头。因此,不允许来源“http:// * * ”。
我的Ajax电话是
var url = http://********:8080/ActiveDirectiveActionRepulsionController.ashx
$.ajax({
type: "POST",
url: url,
async:true,
data: { "REQUESTTYPE": 1, "USERNAME": forgotUsername.val() },
success: function (result) {
if (result == "Username you provided doesnot exist") {
updateTips(result);
}
else if(result == "Sucessfull") {
$(".validateTips").text("All form fields are required.");
$("#Forgot-password").dialog("close");
setDialogMessage("Your password has been send to your registered email id.");
$("#dialog-forgot-message").dialog("open");
}
},
error: function (jqXHR, exception) {
if (jqXHR.status === 0) {
alert('Not connect.\n Verify Network.');
} else if (jqXHR.status == 404) {
alert('Requested page not found. [404]');
} else if (jqXHR.status == 500) {
alert('Internal Server Error [500].');
} else if (exception === 'parsererror') {
alert('Requested JSON parse failed.');
} else if (exception === 'timeout') {
alert('Time out error.');
} else if (exception === 'abort') {
alert('Ajax request aborted.');
} else {
alert('Uncaught Error.\n' + jqXHR.responseText);
}
}
});

答案 0 :(得分:0)
当您向另一个域发送请求时,您必须在该域上设置CORS策略。
至少你必须设置Access-Control-Allow-Origin
