状态:这包括请求的响应代码,这是一种简单的方法来确定执行请求时实际发生了什么。可能的响应代码如下:
200: Successful request (at least one placemark was returned).
400: Bad request (the server was unable to understand the request).
500: Server error (an unknown internal error occurred).
601: Missing query. This means the q parameter was not specified (or was an empty string).
602: Unknown address. This means that the request was performed but no placemarks were found.
603: Unavailable address. The given address could not be returned due to legal or contractual reasons.
610: An invalid Google Maps API key was specified.
620: Too many queries have been performed using the given API key.
