在我的php应用程序中,我必须从地址中了解这个地方的纬度和经度。
我试过这个代码:
$json = file_get_contents("http://maps.google.com/maps/api/geocode/json?address=$address&sensor=false®ion=$region");
$json = json_decode($json);
$lat = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lat'};
$long = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lng'};
但它显示了以下错误:
警告: file_get_contents(http://maps.google.com/maps/api/geocode/json?address=technopark,Trivandrun,kerala,India&sensor=false®ion=IND)函数。文件-获取内容:未能打开流: HTTP请求失败!第4行D:\Projects\lon.php中的HTTP/1.0 400坏请求
请帮我解决这个问题。

使用curl
而不是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;

$address = str_replace(" ", "+", $address);
在file_get_content之前使用上面的代码。方法,使用以下代码
$address = str_replace(" ", "+", $address);
$json = file_get_contents("http://maps.google.com/maps/api/geocode/json?address=$address&sensor=false®ion=$region");
$json = json_decode($json);
$lat = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lat'};
$long = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lng'};
这肯定会奏效的。由于address不支持空格,所以它只支持+符号而不是空格。
