从外部网站获取警报响应

标签: php ajax curl get scrape

我试图通过这个网站获得回复: https://www.primarycare.nhs.uk/publicfn/catchment.aspx?oc=P91012&h=600&w=800&if=0

oc = P91012 - 这是练习标识符。

然后我们有一个邮政编码字段,用户可以检查它们是否在集水区

该网站发出javascript警报,通知用户他们是否在集水区。

是否可以发送一个PHP Curl请求,该请求会向该网站发送邮政编码并检查邮政编码是否在集水区,并将响应请求发回我的网站?

<?php
$POSTurl = 'https://www.primarycare.nhs.uk/publicfn/geocode.ashx';
$fields = array(
'postcode' => urlencode('M41 0UX'),
);

foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string, '&');

$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $POSTurl );
curl_setopt($ch,CURLOPT_POST, count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
$result = curl_exec($ch);



$url = 'https://www.primarycare.nhs.uk/publicfn/catchment.aspx?oc=P91012&h=600&w=800&if=0';
$ch = curl_init();
$result = curl_exec($ch);


curl_close($ch);

?>

1 个答案:

答案 0 :(得分:0)

所以,这是:

问题是,为什么你无法选择正确的响应是因为所有有效的坐标都在NHS的源代码中。我删除了不需要的代码,并通过邮政编码检查了列表中现有坐标的坐标。请记住,如果在原始来源的列表中有任何更改,您还需要更新它。

此外,此代码,技术上不是100%正确,您可能会花更多时间使其更符合您的需求。正如我在评论中所说,这将起到一点点破解作用。

只需复制/粘贴到您的php文件中,然后刷新页面即可。

<强>代码:

<?php
$postcode = 'M41 0UX';
$postcode = urlencode($postcode);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.primarycare.nhs.uk/publicfn/geocode.ashx");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "PostCode=".$postcode);
curl_setopt($ch, CURLOPT_POST, 1);
$result = curl_exec($ch);
if (curl_errno($ch)) {
echo 'Error:' . curl_error($ch);
}
else {
echo $result;
echo '<input id="checker" type="hidden" value="'.$result.'" />';
