在我的一个php应用程序中,我必须从地址中找出该位置的纬度和经度。
我尝试了这段代码:
$json = file_get_contents("http://maps.google.com/maps/api/geocode/json?address=$address&sensor=false®ion=$region"); $json = json_decode($json); $lat = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lat'}; $long = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lng'};
但是它显示以下错误:
警告:file_get_contents(http://maps.google.com/maps/api/geocode/json?address=technopark、Trivandrun,喀拉拉邦,印度&sensor = false&region = IND)[function.file-get-contents]:无法打开流:HTTP请求失败!第4行的D:\ Projects \ lon.php中的HTTP / 1.0 400错误请求
请帮我解决这个问题。
使用curl代替file_get_contents:
curl
file_get_contents
$address = "India+Panchkula"; $url = "http://maps.google.com/maps/api/geocode/json?address=$address&sensor=false®ion=India"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_PROXYPORT, 3128); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); $response = curl_exec($ch); curl_close($ch); $response_a = json_decode($response); echo $lat = $response_a->results[0]->geometry->location->lat; echo "<br />"; echo $long = $response_a->results[0]->geometry->location->lng;
