Curl POST請求返回來自Google Places API的錯誤。 「服務需要密鑰」

Question

我在curl請求時遇到問題 - 將文本搜索發佈到Google Places API。

代碼在下面，但是如果我手動構建URL，請求很好&返回我的正確搜索數據。似乎我的curl請求（POST）由於某種原因未發送發佈數據。

任何人有任何想法我在這裏做錯了嗎？

<?php 

$options = array(
    'url' => 'https://maps.googleapis.com/maps/api/place/textsearch/xml?', 
    'query' => 'my+query+terms', 
    'location' => '43.836296,-79.0851207', 
    'radius' =>'5000', 
    'key' => '_my_api_key_' 
    ); 

$api = array_shift($options); 

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_VERBOSE, TRUE); 
curl_setopt($ch, CURLINFO_HEADER_OUT, TRUE); 
curl_setopt($ch, CURLOPT_URL, $api); 
curl_setopt($ch, CURLOPT_POST, TRUE); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $options); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 

$result = curl_exec($ch); 
$request = curl_getinfo($ch); 

curl_close($ch); 

echo '<pre>'; print_r($request); echo '</pre>'; 
echo '<pre>'; print_r($result); echo '</pre>'; 

return; 

這是我得到的迴應，如果網絡能夠看到數據是否從請求標頭髮布？

我不硝酸鉀WIF你現在有這個排序的，但你可以嘗試這樣的事情。而不是使用POST此使用查詢字符串作爲URL

$key='AIzaSyD3tAJwB463-PpaqVS7pcMqWkkqnki0Kgk'; 
$query='Forfar'; 
$location='52,-2.5'; 
$cacert='c:/wwwroot/cacert.pem'; 
$format='xml'; 


$options = array(
    'url'  => 'https://maps.googleapis.com/maps/api/place/textsearch/'.$format.'?', 
    'query'  => $query, 
    'location' => $location, 
    'radius' => '50', 
    'key'  => $key 
); 


$url = urldecode(array_shift($options) . http_build_query($options)); 


$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLINFO_HEADER_OUT, false); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_CAINFO, $cacert); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2); 

$data = curl_exec($ch); 
$info = curl_getinfo($ch); 

curl_close($ch); 

echo '<textarea cols=100 rows=20>',print_r($data,1),print_r($info,1),'</textarea>'; 

的一部分，並且輸出
