我有 PHP 应用程序，它发送 url 请求以进行地理编码：

http://nominatim.openstreetmap.org/reverse?format=xml&lat=33&lon=34&addressdetails=1

当我复制到浏览器返回 XML 响应。当从 PHP 文件发送的相同 url 的响应为：

<html><head><title>Bandwidth limit exceeded</title></head><body><h1>Bandwidth limit exceeded</h1><p>You have been temporarily blocked because you have been overusing OSM's geocoding service or because you have not provided sufficient identification of your application. This block will be automatically lifted after a while. Please take the time and adapt your scripts to reduce the number of requests and make sure that you send a valid UserAgent or Referer.</p><p>For more information, consult the <a href="http://wiki.openstreetmap.org/wiki/Nominatim_usage_policy">usage policy</a> for the OSM Nominatim server.</body></head>

该请求每 5 分钟发送一次，不违反 1 秒分钟。请求限制。如何避免出现该错误消息？

// Send to nomintaim server reverse geocoding request 
    $url = "http://nominatim.openstreetmap.org/reverse?format=xml&lat=" . $loc['lat'] . "&lon=" . $loc['lng']. "&addressdetails=1";
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0); 
    $result = curl_exec($ch);
    curl_close($ch);

您应该像这样使用 CURLOPT_USERAGENT 和 CURLOPT_REFERER ：

$userAgent = 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.2 (KHTML, like Gecko) Chrome/22.0.1216.0 Safari/537.2';
curl_setopt( $ch, CURLOPT_USERAGENT, $userAgent );
curl_setopt($ch, CURLOPT_REFERER, 'http://www.example.com/1');
