卷曲POST請求從Google Places API返回錯誤。 “服務需要鑰匙”

Question

我在執行curl請求時遇到了麻煩-將文本搜索發布到Google Places API。

代碼在下面，但是如果我手動構建URL，則請求很好並且返回了正確的搜索數據。 似乎我的curl請求（POST）由於某種原因未發送發布數據。

有人知道我在這里做錯了嗎？

<?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;

這是我得到的響應，我是否應該能夠查看是否從請求標頭中發布了數據？

 REQUEST_DENIED
 This service requires an API key.

修改后的工作代碼：

<?php

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

$headers = array(
    'Accept: application/xml',
    'Content-Type: application/xml',
    );

$api = array_shift($options) . http_build_query($options);

$ch = curl_init();

curl_setopt($ch, CURLOPT_VERBOSE, TRUE); // not really needed

curl_setopt($ch, CURLINFO_HEADER_OUT, TRUE);

curl_setopt($ch, CURLOPT_URL, $api);

curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

$result = curl_exec($ch);

// $request = curl_getinfo($ch); // also not needed

curl_close($ch);

echo $result;

return;

我不知道您是否已經對此進行了分類，但是您可以嘗試這樣的操作。 而不是使用POST，而是使用querystring作為url的一部分

$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>';

那輸出
