我正在我的localhost上运行一个html文件。我正在访问我服务器上的php文件。
Javascript在localhost上运行:
var url = "http://www.chartmygolf.com/_TEST_DELETE/exclude.php";
var method = "GET";
var xhr = new XMLHttpRequest();
if ("withCredentials" in xhr) {
// XHR for Chrome/Firefox/Opera/Safari.
xhr.open(method, url, true);
} else if (typeof XDomainRequest != "undefined") {
// XDomainRequest for IE.
xhr = new XDomainRequest();
xhr.open(method, url);
} else {
// CORS not supported.
xhr = null;
}
if (!xhr) {
alert('CORS not supported');
return;
}
// Response handlers.
xhr.onload = function (data) {
var text = xhr.responseText;
alert('Response: ' + text);
};
xhr.onerror = function (data) {
alert('Woops, there was an error making the request.');
};
xhr.send();
我服务器上的php www.mysite.com:
<?php
$referrer = $_SERVER['HTTP_REFERER'];
$parts = parse_url($referrer);
$domain = $parts['host'];
header("Access-Control-Allow-Origin: http://" . $domain);
header('Access-Control-Allow-Methods: GET, POST');
header("Access-Control-Allow-Headers: X-Requested-With");
$arr = array("181K2", "4V419");
echo json_encode($arr);
?>
在Chrome和Edge中,它会进入alert('Woops, there was an error making the request.');
边缘错误:
SEC7120: Origin http://localhost:8080 not found in Access-Control-Allow-Origin header.
SCRIPT7002: XMLHttpRequest: Network Error 0x80700013, Could not complete the operation due to error 80700013.
Chrome错误:
XMLHttpRequest cannot load http://www.chartmygolf.com/_TEST_DELETE/exclude.php. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' is therefore not allowed access.
这让我疯了。我尝试了ajax,现在这种方法,我得到了不一致的结果。我已经在stackoverflow上读取了大量的线程,但没有任何答案可行。 (但是,这些线程似乎已经很久了。)
注意:如果我使用
,我会收到同样的错误 header("Access-Control-Allow-Origin: *");
请帮忙。我失去了对理智的全部控制。

行。找到了。我没有访问我的服务器上的PHP设置。它是Windows服务器。
将它放入php脚本所在目录中的web.config
文件中就可以了。
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="*" />
</customHeaders>
</httpProtocol>
</system.webServer>
</configuration>
如果您不在Windows服务器上,则需要执行上述.htaccess
等等。
