For example, install go jdk on D disk D:\golang\bin
It is recommended to place the project in the D:\golang\src directory. At this time, you can directly read the GOPATH to D:\golang\src. At this time, you can introduce a custom package path, that is, your project name + specific package path
1. The first stupid way: for example, you can build a project under D:\golang\src my-project
The my-project directory level is as follows:
- main/
- utils/
Call the method GetSum of the custom package utils package
package main
import (
"fmt"
"my-project/utils"
)
func main() {
var result int = (100, 200)
(result)
}
You can customize the package name and function GetSum under the package
package utils
func GetSum(a int, b int) int {
return a + b
}
2. The second way of use, the project is recommended
As early as the terminal, enter the command: go mod init and usually follow the git project path.
After executing the go mod init /golang/go-web command, the file is roughly as follows. The following is just a virtual personal git project address, which depends on the individual project situation:
module /golang/go-web go 1.20
Import package test
Create a new testModule/
package testModule
func CountSum(a int, b int) int {
return a + b
}Introduce package test in entry file
package main
import (
"fmt"
"/golang/go-web/testModule"
)
func main () {
res := (23, 88)
("Input calculation result:", res)
