Make money by building services in golang

With the development of the Internet, more and more people are choosing to make money through the Internet. In this process, many people will choose to build their own services to obtain certain benefits. Nowadays, golang has become the choice of many people because it has the characteristics of high concurrency and efficiency, as well as good syntax and rich standard library. This article will introduce how to use golang to build services to make money.

1. Introduction to golang

Go language is a statically typed, compiled programming language developed by Google. This language was born in 2009 and has become the choice of many developers in a short period of time. Compared with other languages, Go language has many advantages, such as fast compilation, high concurrency, rich standard library, and high security. The emergence of Go language provides developers with an efficient, stable and safe development platform.

2. Skills required to build golang services

For golang developers, building services is not difficult. For beginners, they need to master some basic skills, such as golang's basic syntax, common data structures and algorithms, HTTP protocol and database knowledge. In addition, it is also necessary to be familiar with some golang frameworks (such as gin, beego, echo, iris).

3. Steps to build a service

1. Building a service framework

Before you start building a service, you need to choose a framework that suits you. In golang, there are many mature frameworks to choose from. For example, gin, beego, etc., these frameworks provide a wealth of functions and plug-ins to facilitate developers to quickly build their own services. When choosing a framework, you can choose based on your business needs.

2. Writing business logic

Business logic is the core part of building services. When writing business logic, you need to consider the following aspects:

(1) HTTP routing

HTTP routing is a mechanism that distributes requests to the corresponding processing functions. In golang, you can use the routes provided by the framework (such as gin, beego) or write your own routes.

(2) Data storage

Data storage is one of the core parts of the service. In golang, databases such as mysql, mongodb, and redis can be used to store data.

(3) Call other services

If the service needs to call other services, it can be called using http, rpc and other protocols provided by golang.

3. Writing test code

Testing is an important means to ensure service quality. When writing test code, you can use the testing code package provided by golang to check whether your code meets expectations through assertions.

4. Deployment Service

After the service is built, it needs to be deployed. When deploying services, you need to consider the following aspects:

(1) Server selection

Choose the appropriate server according to your needs. For beginners, you can use cloud servers for deployment.

(2) Domain name resolution

When using a domain name, you need to resolve the domain name to your own server.

(3) Server configuration

Server configuration includes installing necessary software and configuring environment variables. For the deployment of golang services, the golang environment needs to be installed.

(4) Service startup

Before starting the service, you need to confirm that the code and configuration are correct. You can use the nohup command or tools such as supervisor to start the service.

4. Commercialization of services

After establishing the service, it needs to be commercialized. There are many ways to commercialize, including advertising, charging, open source, etc. Before commercialization, you need to pay attention to the following issues:

(1) Service quality

Service quality is the basis of commercialization. Before commercialization, the stability and security of the service need to be ensured.

(2) Revenue model

Before commercialization, you need to determine your own revenue model. How to charge and how to provide high-quality services are issues that need to be considered.

(3) Advertising and marketing

Advertising and marketing is an important means to expand the customer base and requires effective advertising.

5. Summary

Building golang service can be said to be a very good choice. It can provide developers with an efficient, stable and secure development platform. In the process of building services, you need to master some basic knowledge and skills, such as golang's basic syntax, common data structures and algorithms, HTTP protocol, and database knowledge. Through these basic knowledge, we can build a feature-rich, stable, and efficient service and obtain certain benefits through commercialization.
