问题描述
我的网站上的用户将在文本框
中输入网址(另一个域中的公共网页)。我想以字符串的形式获取页面的HTML源代码。如何使用客户端脚本执行此操作?
以下是我所做的加载url的操作。但无法弄清楚如何获取html。
<!DOCTYPE html>
< head>
< script>
函数myFunction()
{
document.getElementById(site)。src = document.getElementById(web).value;
}
< / script>
< / head>
< body>
< input id =webtype =textname =user>
< input type =submitvalue =Submitonclick =myFunction()> <峰; br />
< iframe id =sitesrc =width =1200height =1200>< / iframe>
< / body>
< / html>
解决方案
在服务器上创建一个脚本, AJAX,然后使用 cURL
就像这样:
$ ch = curl_init );
$ timeout = 10;
curl_setopt($ ch,CURLOPT_URL,$ url);
curl_setopt($ ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ ch,CURLOPT_CONNECTTIMEOUT,$ timeout);
$ data = curl_exec($ ch);
curl_close($ ch);
并且 $ data
将包含内容。
A user on my website will enter a url (a public page on another domain) in a textbox
. I want to fetch the HTML source code that page as a string. How to do this using client side scripting ?
Following is what I did to load url. But not able to figure out how to fetch html.
<!DOCTYPE html>
<head>
<script>
function myFunction()
{
document.getElementById("site").src=document.getElementById("web").value;
}
</script>
</head>
<body>
<input id="web" type="text" name="user">
<input type="submit" value="Submit" onclick="myFunction()"> <br/>
<iframe id="site" src="" width="1200" height="1200"></iframe>
</body>
</html>
解决方案
Create a script on your server, and call it using AJAX, then use cURL
like so:
$ch = curl_init();
$timeout = 10;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$data = curl_exec($ch);
curl_close($ch);
And $data
will contain the contents.
