Question

没有带有地址的输出。这个PHP代码有什么问题？有什么解决办法吗？

感谢

 <?php
            $str = "Street 1 ZIP City";
            $adr = $str;
            $url = "http://maps.googleapis.com/maps/api/geocode/json?adress=$adr&sensor=false";
            $curl = curl_init();
            curl_setopt($curl, CURLOPT_URL, $url);
            curl_setopt($curl, CURLOPT_HEADER, false);
            curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
            curl_setopt($curl, CURLOPT_ENCODING, "");
            $curlData = curl_exec($curl);
            curl_close($curl);


            $address = json_decode($curlData);
            print_r($address);
            ?>

您的请求字符串中有一个拼写错误：adress而不是address。正确的请求字符串是：

$url = "http://maps.googleapis.com/maps/api/geocode/json?address=$adr&sensor=false";

此外，在将参数粘贴到请求字符串之前，您最好使用 PHP 的 urlencode() 函数来$adr参数。

我已经复制并粘贴了您的代码，其中包含之前列出的更改，即我有：

            $str = "Street 1 ZIP City";
            $adr = urlencode($str);
            $url = "http://maps.googleapis.com/maps/api/geocode/json?address=$adr&sensor=false";
            $curl = curl_init();
            curl_setopt($curl, CURLOPT_URL, $url);
            curl_setopt($curl, CURLOPT_HEADER, false);
            curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
            curl_setopt($curl, CURLOPT_ENCODING, "");
            $curlData = curl_exec($curl);
            curl_close($curl);


            $address = json_decode($curlData);
            print_r($address);

对于此示例，我的浏览器中的输出是：
