不能得到CORS工作在chrome和firefox [英] cant get CORS working in chrome and firefox
问题描述
您尝试对ajax跨域调用，但是有标题的问题。我按照许多教程，但我只是不能得到它的工作。
Hello im trying to ajax cross domain call , but there is problem with headers. I followed many of tutorials but i just cant get it working.
这是我走了多远：
<html>
<head>
<meta http-equiv="Access-Control-Allow-Origin" content="*">
</head>
<body>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js" ></script>
<script>
jQuery.support.cors = true;
$(document).ready(function() {
//this would be done in a common script file if you are going to
//make a lot of these calls
$.ajaxSetup({ type: 'POST', dataType: 'json', contentType: 'application/json', data: {} });
$('#btn').click(function() {
//call the web service with the button is clicked
$.ajax({ url: 'url_external',
data: '{ "some_data:data" }', //ensure the data is enclosed in a quote
success: function (data) {
alert('here...success');
},
complete: function (data) {
alert('here');
}
});
//return false to avoid a postback
return false;
});
});
</script>
<div>
<button id='btn'>Load It</button>
<div id='sayit'></div>
</div>
</body>
</html>
这只适用于IE9。我缺少什么？在Mozilla Firefox和Google Chrome中，有与选项和不允许方法
And this only work in IE9. Am I missing something? In Mozilla Firefox and Google Chrome there is problem with options and 405 Method not allowed
推荐答案
到'url_external'服务器上的所有HTTP响应：
Add this to all of your HTTP responses on the 'url_external' server:
<?php
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: POST, GET, OPTIONS, PUT, DELETE');
header('Access-Control-Allow-Headers', 'Content-Type');
This enables CORS Ajax requests on your url_external server.
您的 url_external 服务器上的origin_resource_sharingrel =nofollow> CORS d可能希望将此微调为...
You'd probably want to fine tuned this to...
header('Access-Control-Allow-Origin: http://yourdomain.com');
...仅允许来自您的网域的CORS请求。
... in order to allow only CORS requests coming only from your domain.
我找到的关于CORS的最佳信息：使用CORS a>。
