Php 来自Google places API的Curl POST请求返回错误&引用；服务需要密钥；

我遇到了一个curl请求的问题——在GooglePlacesAPI上发布了一个文本搜索

下面是代码，但是如果我手动构建URL，请求就可以了&返回正确的搜索数据。我的curl请求（POST）似乎出于某种原因没有发送POST数据

有人知道我做错了什么吗

<?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;

修订的工作代码：

我不知道您现在是否已将其排序，但您可以尝试类似的方法。这将使用查询字符串作为url的一部分，而不是使用POST

$key='AIzaSyD3tAJwB463-PPAQVS7PCMQWKKQNKI0KK'；
$query='Forfar'；
$location='52，-2.5'；
$cacert='c:/wwwroot/cacert.pem'；
$format='xml'；
$options=array(
'url'=>'https://maps.googleapis.com/maps/api/place/textsearch/“.$格式。”？”，
'query'=>$query，
“位置”=>$location，
“半径”=>“50”，
“key”=>$key
);
$url=urldecode（数组移位（$options）。http构建查询（$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）；
$data=curl\u exec（$ch）；
$info=curl\u getinfo（$ch）；
卷曲关闭（$ch）；
回显“”，打印（$data，1），打印（$info，1），“”；

这就产生了

不要使用POST请求，而应尝试使用urlfacepalm的querystring部分中的参数作为GET请求！太尴尬了！是的-get请求是到这里的方法。我认为谷歌只是忽略了任何发布的内容。。。。
