GoogleMap map image request data restrictions Solution

Recently, GoogleMap is no longer completely free of charge for requests to access the map service through APIS. You can generate up to 25000 map download tasks per API every day, and the number of map images is limited to 2500. This will have a great impact on many applications developed using the Google Map API, especially in China. Many of my friends have not found any way to solve this problem.

This method is to set up a Map image Cache Server between our client and the Google Map server, first caching the required Map on the Map image cache server. When the client requests, first, get it from the cache server. If not, get it from the Google Map server, save it locally, and then return it to the client, this reduces the number of requests to the Google Map image server.

Of course, at the beginning of this method, the request volume will still be large, but by the end, the number will decrease.

The general process is as follows:

The process is very simple, and the intermediate implementation method is not complicated. As long as the above functions can be implemented, it is not important to use the platform. The following is the method for defining the map type at the front end:

Tip: the code can be modified before running!
