google geolocator:直接 URL 有效,使用 simplexml_load_file 时状态代码 620
我对这个有点困惑。
我正在尝试查找 lats & lngs 用于商店定位器,并一直在使用 Google 的 Geolocator 及其教程 http:// /code.google.com/apis/maps/articles/phpsqlgeocode.html,但除了可怕的 620 查询过多错误之外,似乎无法返回任何内容。
对我来说真正奇怪的是,如果我将 $request_url 复制到浏览器中,我会按预期获得所有 XML,但是使用 PHP 的 simplexml_load_file($request_url) 总是返回错误代码 620,无论延迟多长时间,无论延迟多少我使用不同的 API 密钥。
有谁知道这是怎么回事?我犯了一些可怕的错误吗?
我的代码如下,请原谅大量的评论和回声:
<?php
$host = 'xxx';
$db = 'xxx';
$u = 'xxx';
$p = 'xxx';
define("MAPS_HOST", "maps.google.com");
define("KEY", "xxx");
// Opens a connection to a MySQL server
$connection = mysql_connect($host, $u, $p);
if (!$connection) {
die("Not connected : " . mysql_error());
}
// Set the active MySQL database
$db_selected = mysql_select_db($db, $connection);
if (!$db_selected) {
die("Can\'t use db : " . mysql_error());
}
// Select all the rows in the markers table
$query = "SELECT * FROM BH_locations";
$result = mysql_query($query);
if (!$result) {
die("Invalid query: " . mysql_error());
}
// Initialize delay in geocode speed
$delay = 0;
$base_url = "http://" . MAPS_HOST . "/maps/geo?output=xml" . "&key=" . KEY;
// Iterate through the rows, geocoding each address
while ($row = @mysql_fetch_assoc($result)) {
echo '<br /><br />row#' . $row['id'] . '<br />';
$geocode_pending = true;
while ($geocode_pending) {
echo 'started while loop at ' . date('G:i:s:u') . '<br />';
$address = $row["address"] . ', ' . $row['city'] . ', ' . $row['state'] . ' ' . $row['zip'];
echo $address . '<br />';
$id = $row["id"];
$request_url = $base_url . "&q=" . urlencode($address);
echo 'request url: ' . $request_url . '<br />';
$xml = simplexml_load_file($request_url) or die("url not loading");
echo '<pre>';
var_dump($xml);
echo '</pre>';
$status = $xml->Response->Status->code;
if (strcmp($status, "200") == 0) {
// Successful geocode
echo '<br /><strong>WOOHOO IT WORKED!!!</strong><br />';
$geocode_pending = false;

mysql_real_escape_string($lat),
mysql_real_escape_string($lng),
mysql_real_escape_string($id));
$update_result = mysql_query($query);

*/
} else if (strcmp($status, "620") == 0) {

echo 'error 620<br /><br />';
} else {

I'm a little confused about this one.
I'm trying to lookup lats & lngs for a store locator and have been working with Google's Geolocator and their tutorial at http://code.google.com/apis/maps/articles/phpsqlgeocode.html, but can't seem to return anything other than the dreaded 620 Too many queries error.
What's really strange to me is that if I copy my $request_url into a browser I get all the XML as expected, but using PHP's simplexml_load_file($request_url) always returns error code 620, no matter how long of a delay, no matter how many different API keys I use.
Does anyone know what's up with this? Am I making some horrendous mistake?
My code is below, please excuse extensive comments and echoes:

$db = 'xxx';
$u = 'xxx';
$p = 'xxx';

$connection = mysql_connect($host, $u, $p);
if (!$connection) {
die("Not connected : " . mysql_error());

// Set the active MySQL database
$db_selected = mysql_select_db($db, $connection);
if (!$db_selected) {
die("Can\'t use db : " . mysql_error());
}
// Select all the rows in the markers table
$query = "SELECT * FROM BH_locations";
$result = mysql_query($query);
if (!$result) {
die("Invalid query: " . mysql_error());
}
// Initialize delay in geocode speed
$delay = 0;
$base_url = "http://" . MAPS_HOST . "/maps/geo?output=xml" . "&key=" . KEY;

您很可能发送太多请求且速度太快。
请参阅 Google 地图中的 G_GEO_TOO_MANY_QUERIES 常量文档。
You are sending too many requests too fast most likely.
See G_GEO_TOO_MANY_QUERIES constant from the Google Maps documentation.
