1 Introduction
2021 is a particularly important year. Many innovative companies and technology entrepreneurs have begun to look for new opportunities and breakthrough market ideas. In the past two years, many Internet companies have transformed into platform companies, and this change has promoted the emergence of Web developers. These Web developers have brought a large number of application scenarios, complex data and information needs. We can call web developers the "second batch of Internet people". In such an environment, how to implement a series of map functions such as map query and address resolution in a cheaper and simpler way is an issue they urgently need to solve.
Google Maps API is a widely used map service. It provides a series of API interfaces available to developers, including static maps, satellite maps, navigation guidance, search, direction calculation and other services in many fields. This article will use this API as the entry point, combined with Go language programming knowledge, to show how to use this API and its related features to interact with users by writing a complete map query tool.
Before reading this article, readers first need to have a basic understanding of the Go language, understand some of the syntax and data types in the Go language, and be able to write simple programs. If the reader is not familiar with it yet, it is recommended to learn the basic knowledge of Go language first and install and configure the relevant development environment.
If readers already have basic knowledge of Go language, this article will elaborate on the following aspects:
- Go language programming environment construction;
- Use third-party libraries to access the Google Maps API;
- Implement the user interface of the map query tool through the front-end page;
- Implementation of back-end server to provide map query service;
- Service deployment and operation and maintenance;
finally, some pitfalls and precautions will also be shared for readers’ reference.
