Question

我一直在使用谷歌地理编码v3大约6个月，但突然间它停止工作（我得到610错误）。它只在上周左右停止。

然后我遇到了这个（请参阅页面顶部的粉红色方框！）：https://developers.google.com/maps/documentation/geocoding/v2/

我已阅读所有文档，但不确定从哪里开始！

我希望这是一个很小的变化，因为需要很长时间才能实现这一目标，任何人都可以帮忙吗？

当您将坐标存储在数据库中时，最好在插入新记录时进行地理编码。即

require("dbinfo.php");//Your database parameters
//Connect to database
$dbh = new PDO("mysql:host=$host;dbname=$database", $username, $password);
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
try {
    //Prepare query
    $name = "%".$company."%";//Wildcard for PDO paramerter
    $countSql = "SELECT COUNT(*) FROM markers WHERE `name` LIKE ?"; 
    $countStmt = $dbh->prepare($countSql);
    // Assign parameter
    $countStmt->bindParam(1,$name);
    //Execute query
    $countStmt->execute();  
    // check the row count  
    if ($countStmt->fetchColumn() == 0) { #1 EDIT changed >0 to ==0
        echo "No row matched the query."; //EDIT  From Row
        $q =$address.','.$city.','.$post_code.',UK'; 
        echo "\n";
        $base_url = "http://maps.googleapis.com/maps/api/geocode/xml?address=";
        $request_url = $base_url.urlencode($q)."&sensor=false";
        $xml = simplexml_load_file($request_url) or die("url not loading");
        if($xml->status=="OK"){#2
            // Successful geocode
            $lat = $xml->result->geometry->location->lat;
            $lng = $xml->result->geometry->location->lng; 
            $insertSql ="INSERT INTO markers (`name`, `address`, `lat`, `lng`, `type`, `link`) VALUES (?,?,?,?,?,?)";
            $insertStmt = $dbh->prepare($insertSql);
            // Assign parameter
            $insertStmt->bindParam(1,$company);
            $insertStmt->bindParam(2,$address); 
            $insertStmt->bindParam(3,$lat);
            $insertStmt->bindParam(4,$lng);
            $insertStmt->bindParam(5,$type);
            $insertStmt->bindParam(6,$link);
            //Execute query
            $insertStmt->execute();
        } #2
        else{
            "No rows inserted."; 
        }#2
    } #1
    else {#1
    echo "Rows matched the query."; //EDIT From No row
    } #1 
}// End try 


catch(PDOException $e) {
    echo "I'm sorry I'm afraid you can't do that.". $e->getMessage() ;// Remove or modify after testing 
    file_put_contents('PDOErrors.txt',date('[Y-m-d H:i:s]').", myFile.php, ". $e->getMessage()."\r\n", FILE_APPEND);  
 }

我已将您的代码转换为PDO，因为建议停止使用mysql_函数，因为这些函数已弃用。

我让你实现了如何处理不返回坐标的地理编码。您还可以检查并处理以下状态代码

OVER_QUERY_LIMIT

ZERO_RESULTS

REQUEST_DENIED

INVALID_REQUEST

请参阅pastebin了解状态代码实现

根据我们之前的评论，只需要进行一些更改就可以让您重新站起来。

这些是，更改v3地理编码的地址

define("MAPS_HOST", "maps.googleapis.com");
$base_url = "http://" . MAPS_HOST . "/maps/api/geocode/xml?";
$request_url = $base_url . "address=" . urlencode($address) . "&sensor=false";

其次，更改返回的xml文件中的路径以设置lat / long

$coordinates = $xml->Response->Placemark->Point->coordinates;
$coordinatesSplit = split(",", $coordinates);
// Format: Longitude, Latitude, Altitude
$lat = $coordinatesSplit[1];
$lng = $coordinatesSplit[0];

可以完全替换为

$lat = $xml->result->geometry->location->lat;
$lng = $xml->result->geometry->location->lng;

关于阻止其超越地理编码限制的下一篇文章。您需要做的是在运行地理编码之前设置一个简单的检查。

while ($row = @mysql_fetch_assoc($result)) {
    if (!($row['lat'] * 1)) {// add this line
        $geocode_pending = true;
            while ($geocode_pending){
                //do geocoding stuff
            }
        }
    }// add this close
}
