1.5 获取文件路径

package main

import (
    "fmt"
    "os"
    "path/filepath"
)

func main() {
    ex, err := os.Executable()
    if err != nil {
        panic(err)
    }

    // Path to executable file
    fmt.Println("绝对路径: ", ex) // 绝对路径

    // Resolve the direcotry
    // of the executable
    exPath := filepath.Dir(ex)
    fmt.Println("执行的路径，文件所在目录Executable path:" + exPath)

    // Use EvalSymlinks to get
    // the real path.
    realPath, err := filepath.EvalSymlinks(exPath)
    if err != nil {
        panic(err)
    }
    fmt.Println("Symlink evaluated:" + realPath)
}


/*
绝对路径:  /private/var/folders/tw/g0l_2m8s7y5690qqjdsvrzd00000gn/T/___go_build_b_go
执行的路径，文件所在目录Executable path:/private/var/folders/tw/g0l_2m8s7y5690qqjdsvrzd00000gn/T
Symlink evaluated:/private/var/folders/tw/g0l_2m8s7y5690qqjdsvrzd00000gn/T
