GO语言使用自定义包

Windows系统下C语言中使用自定义包的方法:

首先明确GOPATH的路径,执行go env | findstr GOPATH

1
2
3
4
C:\Users\CHORDER>go env | findstr GOPATH
set GOPATH=C:\Users\CHORDER\go

C:\Users\CHORDER>

接着在GOPATH目录中创建相应的自定义包,这里定义一个example包,并创建两个源码文件src1.gosrc2.go,源码内容如下:

C:\Users\CHORDER\go\src\chorder.net\example\src1.go

1
2
3
4
5
6
7
8
9
10
11
package example

import "fmt"

func init(){
fmt.Printf("\nchorder.net/example/src1.go init() has been called.")
}

func Src1(){
fmt.Printf("\nchorder.net/example/src1.go Src1() has been called.")
}

C:\Users\CHORDER\go\src\chorder.net\example\src2.go

1
2
3
4
5
6
7
8
9
10
11
package example

import "fmt"

func init(){
fmt.Printf("\nchorder.net/example/src2.go init() has been called.")
}

func Src2(){
fmt.Printf("\nchorder.net/example/src2.go Src1() has been called.")
}

编写代码调用这两个包中的方法:

packge_test.go

1
2
3
4
5
6
7
8
package main

import "chorder.net/example"

func main(){
trueexample.Src1()
trueexample.Src2()
}

执行结果:

1
2
3
4
5
6
>go run packge_test.go

chorder.net/example/src1.go init() has been called.
chorder.net/example/src2.go init() has been called.
chorder.net/example/src1.go Src1() has been called.
chorder.net/example/src2.go Src1() has been called.
