Baidu included on the map is a common location information, and if there are some special places are not included Baidu map, LBS Baidu cloud service provided allows us to easily own collection of location information (such as toilets attractions, etc.)
About LBS cloud
LBS is Baidu map for the launch of the LBS developer platform-level services, combined with the existing Maps API and SDK services through an open server storage and computing power, providing real-time location data mass storage, retrieval, display integrated solutions
1 implemented based LBS: Cloud storage 2, 3 retrieves the cloud, the cloud geocoding 4, an inverse cloud geographic coding
LBS application for registration and key
LBS using cloud services must have a Baidu account, after landing the account open LBS application cloud services, to use LBS
Cloud services must apply key
Key Application Types
Select the type of application required for the back-end application server; browser on the application by the end js code
Check the required service
Setting test mode and whitelist
Here ip address will be prompted to enter the wrong format (These are the server configuration) browser is slightly different
LBS quota management
Baidu offers certain quota for LBS cloud services, more than the amount necessary to spend money on free
This feature provides detailed flow chart and balances, and the management is very convenient. General test development and small-scale trial is sufficient, this is Baidu also did a good job.
LBS Download
Baidu provides a detailed description of the development, documentation and code examples available for download
Note LBS into cloud cloud cloud storage and retrieval
Cloud storage is a database-like DML statements responsible for the new, delete, and modify tables, queries the cloud to retrieve real data.
