Question

警報響應我想OT找出客場取得本網站的響應： https://www.primarycare.nhs.uk/publicfn/catchment.aspx?oc=P91012&h=600&w=800&if=0

OC = P91012 - 這是慣例標識。

然後我們有一個郵政編碼場，其中用戶檢查，如果他們是在集水區

該網站發出JavaScript警告如果他們/或不在集水區通知用戶。

是否可以發送PHP Curl請求，向本網站發送郵政編碼並檢查郵政編碼是否位於集水區，並將回覆發送回我的網站？

<?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); 

?> 

Answer 1

所以，在這裏，它是：

的問題，爲什麼你不是不能挑適當的反應是因爲所有有效座標是NHS的源代碼。我刪除了不需要的代碼，並通過郵編和列表中的現有座標檢查座標。請記住，如果原始數據源中的任何內容都將在列表中進行更改，則還需要進行更新。

此外，此代碼，技術上是不是100％正確並且可能你會花更多的時間使它更正確地滿足您的需求。正如我在評論中所說的那樣，這將起到一點作用。

只需複製/粘貼到您的PHP文件，並刷新頁面。

代碼： '？難道......'

<?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.'" />';
