Geocoding API is a service interface provided by Baidu. It is mainly used to provide translation services from address resolution to latitude and longitude coordinates or from latitude and longitude coordinates to addresses, you can send a request to receive returned data in JSON or XML format.
Most of the code and solutions provided on the Internet are based on Google
After a year-long non-public test, Google finally published the beta version of Google Analytics API. Since last OctoberGoogle once revealed that they are about to launch the Service's API. Google Analytics

In this code, you can also use the mapabc code "mabc_saddr:" be0000020f "and mabc_daddr:" be000005cb "obtained from geocoding "". Next we will use another interface http:/
It is now often necessary to provide some information about location based on the location provided by the user. Sometimes you can directly determine the latitude and longitude of the user, sometimes not necessarily determine the user's latitude and longitude information, the user is through the input of some road name, landmark building or store name location, but our database may not be stored in the user may enter the latitude of these location information, At this point you can use some map-
