环境:

win8.1 x64, go1.3 x64

程序调用方式:

问题描述:

只要是当前文件中含有空格程序就报错,错误如下:

The system cannot find the file specified. goroutine 16 [running]: runtime.panic(0x4d6740, 0xc082005d70) c:/go/src/pkg/runtime/panic.c:279 +0x11f main.is_file(0xc082000170, 0x7) D:/www/scripts/go/test/test.go:24 +0x8b main.main() D:/www/scripts/go/test/test.go:15 +0x9a goroutine 17 [runnable]: runtime.MHeap_Scavenger() c:/go/src/pkg/runtime/mheap.c:507 runtime.goexit() c:/go/src/pkg/runtime/proc.c:1445 goroutine 18 [runnable]: bgsweep() c:/go/src/pkg/runtime/mgc0.c:1976 runtime.goexit() c:/go/src/pkg/runtime/proc.c:1445 goroutine 19 [runnable]: runfinq() c:/go/src/pkg/runtime/mgc0.c:2606 runtime.goexit() c:/go/src/pkg/runtime/proc.c:1445 

程序内容:

package main

import (
	"flag"
	"fmt"
	"io/ioutil"
	"os"
)

func main() {
	file_name := flag.String("f", "", "文件名")

	flag.Parse()
	if *file_name != "" {
		is_file(*file_name)
	} else {
		fmt.Printf("test\n")
	}
}

func is_file(file_name string) {
	file, err := os.Open(file_name)
	if err != nil {
		panic(err)
	}
	defer file.Close()

	input, _ := ioutil.ReadAll(file)
	fmt.Println(input)
}



谢谢...
