我想使用javascript从网站获取页面。 我有喜欢的网址:如何在javascript中通过url获取页面
http://not-my-site.com/random
从“随机”我将被重定向到的网址另一个(随机)页面。
邮差做我喜欢的一切:)它是整个页面(html)。但我怎么能做到这一点从JavaScript?
我试过CORS alredy按照这个指南http://www.html5rocks.com/en/tutorials/cors/但没有成功。我还只是得到一个错误:
XMLHttpRequest cannot load http://not-my-site.com/random.
No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.
从教程代码:
function createCORSRequest(method, url) {
var xhr = new XMLHttpRequest();
if ("withCredentials" in xhr) {
// Check if the XMLHttpRequest object has a "withCredentials" property.
// "withCredentials" only exists on XMLHTTPRequest2 objects.
xhr.open(method, url, true);
} else if (typeof XDomainRequest != "undefined") {
// Otherwise, check if XDomainRequest.
// XDomainRequest only exists in IE, and is IE's way of making CORS requests.
xhr = new XDomainRequest();
xhr.open(method, url);
} else {
// Otherwise, CORS is not supported by the browser.
xhr = null;
}
return xhr;
}
var xhr = createCORSRequest('GET', 'http://not-my-site.com/random');
if (!xhr) {
throw new Error('CORS not supported');
}
xhr.onload = function() {
var responseText = xhr.responseText;
console.log(responseText);
// process the response.
};
xhr.onerror = function() {
console.log('There was an error!');
};
xhr.send();
而且我也试过共同XHR像这样(得到了同样的错误):
var xhr = new XMLHttpRequest();
xhr.open('GET', 'http://not-my-site.com/random', true);
xhr.send();
请问您可以发布代码给你这个错误吗? (如果它是MCVE,额外的奖励) – fxm 2014-12-07 00:47:58
没有什么可以尝试一下cors;无论是远程站点实现它,它的工作原理或它没有,除了在后面的情况下使用服务器端代理或服务,如YQL,没有什么可以做... – dandavis 2014-12-07 01:00:32
最后,我用了Whatever Origin。工作正常... http://stackoverflow.com/questions/15005500/loading-cross-domain-html-page-with-jquery-ajax – Alendorff 2014-12-07 02:01:07
