X 域 Post 使用 XMLHttpRequest
X-Domain Post using XMLHttpRequest
我有以下代码块:
console.log(1);
var xhr = new XMLHttpRequest();
xhr.open('POST', 'http://anothersite.com/deal-with-data.php');
xhr.setRequestHeader('Content-type','application/x-www-form-urlencoded');
console.log(2);
xhr.onreadystatechange = function () {
console.log(3);
if (this.status == 200 && this.readyState == 4) {
console.log(4);
xhr.send("formType="+thisFormType+
"&mediaCode="+3478+
"&car="+carID+
"&title="+$('#title').val()+
"&firstname="+$('#firstname').val()+
"&surname="+$('#lastname').val()+
"&tel="+$('#telephone').val()+
"&email="+$('#emailaddress').val()+
"&postcode="+$('#postcode').val()+
"&add1="+$('#add1').val()+
"&add2="+$('#add2').val()+
"&add3="+$('#add3').val()+
"&town="+""+
"&county="+""+
"&optin-post="+$('#optin-post').attr('checked')+
"&optin-tel="+$('#optin-tel').attr('checked')+
"&optin-email="+$('#optin-email').attr('checked')+
"&optin-sms="+$('#optin-sms').attr('checked')+
"&tarID="+targetID+
"&campID="+campaignID+
"&subID="+subjectID
);
console.log(5);
}
}
console.log(6);
所以,除了 xhr.onreadystatechange
之外的所有东西都会触发 - 我从来没有得到 console.log(4)
- 我在 PHP 和 htaccess 中启用了 Access-Control-Allow-Origin
以及尝试名副其实的大量 Javascript post 函数。
问题是,根据要求,我需要 post 不支持服务器端语言的服务器上表单中的数据 - 到另一个域来处理数据。
有什么想法吗?这让我发疯!
编辑:我也用 $.ajax
试过了
$.ajax({
url: 'http://anothersite.com/deal-with-data.php',
type: "post",
crossDomain: true,
data: {
"formType":thisFormType,
"mediaCode":3478,
"car":$('#car').val(),
"title":$('#title').val(),
"firstname":$('#firstname').val(),
"surname":$('#surname').val(),
"tel":$('#telephone').val(),
"email":$('#email').val(),
"postcode":$('#postcode').val(),
"add1":$('#add1').val(),
"add2":$('#add2').val(),
"add3":$('#add3').val(),
"town":"",
"county":"",
"optin-post":$('#opt-post').attr('checked'),
"optin-tel":$('#opt-tel').attr('checked'),
"optin-email":$('#opt-email').attr('checked'),
"optin-sms":$('#opt-sms').attr('checked'),
"tarID":targetID,
"campID":campaignID,
"subID":subjectID
},
beforeSend: function() {
$('#submit').val('Sending...').attr('disabled','disabled');
},
success: function(data) {
console.log("success call");
console.log(data);
},
error: function(err) {
console.log("error call");
console.log(err);
}
});
现在我也尝试在 httpd.conf 中启用它:https://serverfault.com/a/378776/36601
你不应该在 xhr.onreadystatechange 中传递 xhr.send
。执行如下操作:
var xhr = new XMLHttpRequest();
xhr.open('POST', 'myurl', true);
xhr.onload = function () {
if (xhr.status === 200 && xhr.readyState === 4) {
// do some cool stuff
console.log('You got a successfull request');
}
};
xhr.setRequestHeader('Content-type','application/x-www-form-urlencoded');
xhr.send(); // pass your params here
您可能还需要设置 Access-Control-Allow-Methods:POST header。阅读更多关于 https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS
