使用v3的Google地理编码不会显示错误 [英] Google geocoding using v3 not showing error
问题描述
请在下面的代码上提供帮助。发生的事情是,当我点击一个按钮时,我得到了一个地方名称的经纬度。但是,最近它不起作用。它会打印出地址x未通过地理编码,收到状态请注意,x是给定的地址,并且不会给出状态码。
Kindly help on the code below. What happens is that I get the latitude and longitude of the name of a place when I click on a button. However, of late, it is not working. It prints that "Address x failed to Geocode. Received status " Note that x is a given address and no status code is given.
$id=$_REQUEST['id'];
define("MAPS_HOST", "maps.googleapis.com");
define("KEY", "xxxxxxx");
$query = "SELECT * FROM markers WHERE mid = $id LIMIT 1";
$result = mysql_query($query);
if (!$result) {
die("Invalid query: " . mysql_error());
}
// Initialize delay in geocode speed
$delay = 0;
$base_url = "http://" . MAPS_HOST . "/maps/api/geocode/xml?address=";
if($row = @mysql_fetch_assoc($result)){
$geocode_pending = true;
$address = $row["address"];
while ($geocode_pending) {
$request_url = $base_url . urlencode($address) . "&sensor=false&key=" . KEY;
$xml = simplexml_load_file($request_url) or die("url not loading");
$status = $xml->Response->Status->code;
if (strcmp($status, "200") == 0) {
// Successful geocode
$geocode_pending = false;
$coordinates = $xml->Response->Placemark->Point->coordinates;
//$coordinatesSplit = split(",", $coordinates);
// Format: Longitude, Latitude, Altitude
//$lat = $coordinatesSplit[1];
//$lng = $coordinatesSplit[0];
list($lat,$lng) = explode(",",$coordinates);
$query = sprintf("UPDATE markers " .
" SET lat = '%s', lng = '%s' " .
" WHERE mid = '%s' LIMIT 1;",
mysql_real_escape_string($lng),
mysql_real_escape_string($lat),
mysql_real_escape_string($id));
$update_result = mysql_query($query);
if (!$update_result) {
die("Invalid query: " . mysql_error());
}else{
echo "$lat;$lng";
}
} else if (strcmp($status, "620") == 0) {
// sent geocodes too fast
$delay += 100000;
} else {
// failure to geocode
$geocode_pending = false;
echo "Address " . $address . " failed to geocode. ";
echo "Received status " . $status . "
\n";
}
usleep($delay);
}
}
推荐答案
I 'm不知道你的代码是基于哪个API的,但是当前API的响应不适用于这些行:
I'm not sure on which API your code is based on, but the response of the current API will not work with these lines:
$status = $xml->Response->Status->code;
if (strcmp($status, "200") == 0) {
不是元素响应,
状态
或代码
,此外响应将不包含数字状态码。
There are no elements Response
,Status
or code
, furthermore the response will not contain a numeric status-code.
使用它代替:
use this instead:
$status = $xml->status;
if (strcmp($status, "OK") == 0) {
修复其余的代码,请看看返回的XML的结构,也没有元素 Placemark
, Point
和坐标
。
To fix the rest of the code please take a look at the structure of the returned XML, there are also no elements Placemark
,Point
and coordinates
.
应该是:
it should be:
$lat = $xml->result->geometry->location->lat;
$lng = $xml->result->geometry->location->lng;
