【微信开发】-发送位置获取周边信息及生成百度全景静态图API，主要代码在private function receiveLocation($object)

百度地图全景静态图API与静态图API类似，可轻松实现将全景地图以图片形式嵌入到您的应用中。您只需要设置图片尺寸、经纬度坐标等参数，发送HTTP请求访问百度地图全景静态图服务，便可在您的PC浏览器、手机浏览器、移动APP或者车机显示屏中以图片形式显示您的全景图。

该套API免费对外开放，使用前请先申请密钥。注意：申请密钥时，请选择AK的应用类型为 “for server”。

您在使用百度地图Web服务 API之前，请先阅读百度地图API使用条款。任何非营利性应用请直接使用，商业应用请参考使用须知。
