Question

我正在尝试在我的网站上实施谷歌地图标记。但它只显示蓝屏和标记。我无法在那里看到任何地图。请参阅下面的代码。我用mykey替换了apikey。

    <?

define("MAPS_HOST", "maps.google.com");

define("KEY", "mykey"); // Place your API Key here...

// Get our address (from a database query or POST

$address = "india";

// Build our URL from the above...

$base_url = "http://" . MAPS_HOST . "/maps/geo?q=" . $address . "&output=csv" . "&key=" . KEY;



// Initalise CURL

$c = curl_init();

// Get the URL and save the Data

curl_setopt($c, CURLOPT_URL, $base_url);

curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);

// Save location data

$csvPosition = trim(curl_exec($c));

// Close the connection

curl_close($c);





// Split pieces of data by the comma that separates them

list($httpcode,$elev, $lat, $long) = preg_split("/[,]+/", $csvPosition);

?>

Answer 1

这只是猜测，但我会说有关您的地图请求的信息不正确，否则Google无法找到您要搜索的地址（这似乎不太可能）。尝试将完整格式的URL粘贴到浏览器中，并手动检查您要返回的CSV数据。

如果Google无法为您的地址提供地理编码，那么您将获得0,0作为纬度/经度，即非洲沿海多哥下方的海洋。可能会解释你所看到的蓝色方块。

Answer 2

您似乎正在尝试使用deprecated v2 geocoder。使用v3 Geocoding Service instead

Issues have been reported with the v2 version of the API
