CURL 发布数据的问题

Question

我会保持简短。

我正在尝试将值发布到远程表单。

这段代码运行良好：

$url = "http://eirestudio.net/blog/"; // URL to POST FORM.

$post_fields = "s=test"; 

$ch = curl_init(); // Initialize a CURL session.
curl_setopt($ch, CURLOPT_URL, $url); // Pass URL as parameter.
curl_setopt($ch, CURLOPT_POST, 1); // use this option to Post a form
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields); // Pass form Fields.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // Return Page contents.
$result = curl_exec($ch); // grab URL and pass it to the variable.
curl_close($ch); // close curl resource, and free up system resources.
echo $result; // Print page contents.

但是当我在另一个域上测试它失败了：

$url = "http://jobbank.fas.ie/servlet/Watis?SESS=50306_1&TEMPLATE=WWW_JS_VAC_TEXTSEARCH.HTM&BACK=TEMPLATE%3DWWW_JS_VAC.HTM"; // URL to POST FORM.

$post_fields = "TEXTSEARCH.JOBNAME=$search"; //

$ch = curl_init(); // Initialize a CURL session.
curl_setopt($ch, CURLOPT_URL, $url); // Pass URL as parameter.
curl_setopt($ch, CURLOPT_POST, 1); // use this option to Post a form
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields); // Pass form Fields.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // Return Page contents.
$result = curl_exec($ch); // grab URL and pass it to the variable.
curl_close($ch); // close curl resource, and free up system resources.
echo $result; // Print page contents.

你能发现第二段代码有什么问题吗？

Answer 1

因为新知识而开始另一个答案。我很无聊，决定调查一下。您的 postvars 必须包含所有输入字段，其中您只有 TEXTSEARCH.JOBNAME。网站必须全部要求它们或默认返回模板页面。

所以：

$search = 'plumber';
$post_fields = "TEXTSEARCH.JOBNAME=$search";

$post_fields .="&REQUEST.WWW_JS_VAC_TEXTSEARCH=Search";
$post_fields .="&TEXTSEARCH.DESCRIPTION= &TEXTSEARCH.LOCATION=";

如果你这样填写，那么你会得到一个回复​​，其中包括“你的搜索得到 x 个结果”之类的内容

Answer 2

尝试在 curopt_postfields 中传递所有帖子参数。你在 url 中传递了一些

$url = "http://jobbank.fas.ie/servlet/Watis";
$post_fields = "TEXTSEARCH.JOBNAME=$search&SESS=50306_1&TEMPLATE=WWW_JS_VAC_TEXTSEARCH.HTM&BACK=TEMPLATE%3DWWW_JS_VAC.HTM";
