Golang:Golang生成动态库及调用

CODE

plugin.so

package main



import (

    "fmt"

    )



func DCall(){
    fmt.Println("plugin.so was called") 
}

func DCallWithParam(msg string){
    fmt.Println("参数内容为:",msg) 
}


func main() {



    fmt.Println("goroute全部退出")

}

package main

import (
    "plugin"
)

func main() {

    //加载动态库
    p, err := plugin.Open("plugin.so")
    if err != nil {
        panic(err)
    }
    //查找函数   
    f, err := p.Lookup("DCall")
    if err != nil {
        panic(err)
    }
    //转换类型后调用函数   
    f.(func())()

    f2, err := p.Lookup("DCallWithParam")
    if err != nil {
        panic(err)
    }

    //带参函数的调用
    f2.(func(string))("hello world,plugin.so")

编译动态库
go build --buildmode=plugin plugin.go
调用动态库
go run pluginload.go
