使用php,API自动获取纬度和经度 [英] Get latitude and longitude automatically using php, API
问题描述
在我的一个php应用程序中,我必须找出地址的经纬度。
我试过这段代码:
$ json = file_get_contents(http://maps.google.com/maps/api/geocode/json?address=$address&sensor=false& ;区域= $区域);
$ json = json_decode($ json);
$ lat = $ json-> {'results'} [0] - > {'geometry'} - > {'location'} - > {'lat'};
$ long = $ json-> {'results'} [0] - > {'geometry'} - > {'location'} - > {'lng'};
但它显示以下错误:
< blockquote>
警告:file_get_contents(http://maps.google.com/maps/api/geocode/json?address=technopark,Trivandrun,kerala,India& sensor = false& region = IND)[ function.file-get-contents]:无法打开流:HTTP请求失败! HTTP / 1.0 400请求错误D:\Projects\lon.php on line 4
请帮我解决这个问题。
curl
而不是 file_get_contents : $ address =印度+ 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;
回声< br />;
echo $ long = $ response_a-> results [0] - > geometry-> location-> lng;
In one of my php applications I have to find out the latitude and longitude of the place from address.
I tried this code:
$json = file_get_contents("http://maps.google.com/maps/api/geocode/json?address=$address&sensor=false®ion=$region");
$json = json_decode($json);
$lat = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lat'};
$long = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lng'};
But it is showing the following Error :
Warning: file_get_contents(http://maps.google.com/maps/api/geocode/json?address=technopark, Trivandrun, kerala,India&sensor=false®ion=IND) [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request in D:\Projects\lon.php on line 4
Please help me to solve this issue.
解决方案 Use curl
instead of 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;
