file_Get_contents in javascript

Question

我想使用从我的网站执行的JavaScript从其他网站获取数据。

Answer 1

PHPJS网站上有一些将PHP函数转换为Javascript的很好的方法。

Answer 2

In general, unless they expose the data with JSON-P , you can't thanks to the security considerations imposed by the same origin policy .

Recent browsers support a permissions system where a remote site can allow JavaScript running on a remote site to make a request. Flash provides a similar system, so can act as an intermediary. Both of these require the cooperation of the remote site.

The usual work around is to use a proxy service, either running on your own system (so JS makes the request to the same server, which fetches the data from the remote site) or a third-party service like YQL .

Answer 3

Javascript is limited by the same-domain security policy. The only way to get data from other sites is to use JSONP or build a proxy on your own host that lets you curl content from other sites.

Answer 4

Use jQuery:

$.post( 'http://some.website.com/file.js', function(result){
    alert(result);
});

You may not fetch anything but JavaScript or JSON.

Or try this answer: How do I send a cross-domain POST request via JavaScript?

Answer 5

必须在服务器端完成-发送ajax请求 ，运行所需的PHP，并检查responseText属性以查看结果。

Answer 6

That really depends on what you mean by "data". Try using AJAX if its just for simple requests.
