如何在外部网站上提交表单并生成HTML？ [英] How to submit form on an external website and get generated HTML?

问题描述

我想用PHP创建一个脚本（可能需要JS）将POST数据发送到另一个网页并返回结果。

I would like make a script using PHP (probably need JS) to send POST data to another webpage and get the result back.

例如，域A将有一个带有文本框和提交按钮的表单，域B将有一个脚本，它将填充文本框并按下提交按钮并返回生成的HTML页面。

For example, Domain A will have a form with a textbox and submit button, and Domain B will have a script which will fill the textbox and press the submit button and return the generated HTML page.

推荐答案

以下几行代码可以写在另一个PHP脚本上，

The following lines of code can be written on another php script,

//set POST variables
$url = 'the website from which you need data through post';
$fields = array(
            //post parameters to be sent to the other website
            'text'=>urlencode($_POST['text']), //the post request you send to this  script from your domain.
        );

//url-ify the data for the POST
foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string,'&');

//open connection
$ch = curl_init();

//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_POST,count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS,$fields_string);

//execute post
$result = curl_exec($ch);

//close connection
curl_close($ch);

现在$ result将包含从其他网站收到的文本。

Now $result will contain the text received from the other website.
