Why cant I open a text file when I use the wrong file extension while trying to open it?
问题
我正在尝试使用Go语言读取一个.txt文件，但是我一直被告知程序找不到指定的文件，即使我使用完整的路径也是如此。然而，我现有的代码在读取.go文件时没有问题。
有什么帮助吗？
package main
import (
"bufio"
"fmt"
"log"
"os"
)
func main() {
// 打开输入文件，出错时退出。
inputFile, err := os.Open("main.go")
if err != nil {
log.Fatal("Error opening input file:", err)
}
defer inputFile.Close()
scanner := bufio.NewScanner(inputFile)
for scanner.Scan() {
fmt.Println(scanner.Text())
}
if err := scanner.Err(); err != nil {
log.Fatal(scanner.Err())
}
}
以上是你提供的代码。
英文:
I'm trying to read a .txt file using Go, but I keep getting told that the program cannot find the specified file, even when I use the complete path to it. However, the code I have has no problem reading .go files.
Help?
package main
import (
"bufio"
"fmt"
"log"
"os"
)
func main() {
// Open an input file, exit on error.
inputFile, err := os.Open("main.go");
if err != nil {
log.Fatal("Error opening input file:", err)
}
defer inputFile.Close()
scanner := bufio.NewScanner(inputFile)
for scanner.Scan() {
fmt.Println(scanner.Text())
}
if err := scanner.Err(); err != nil {
log.Fatal(scanner.Err())
}
}

你可以在主函数的开头看到你正在添加这段代码：
http://play.golang.org/p/DqnivLi1Z2
cwd, err := os.Getwd()
if err != nil {
log.Fatal("os.Getwd ", err)
}
log.Println("当前目录", cwd)
files, err := ioutil.ReadDir(cwd)
if err != nil {
log.Fatal("ioutil.ReadDir", err)
}
for idx, finfo := range files {
log.Println(idx, " ", finfo.Name)
}
英文:
You can see where you are adding this snippet of code at the beginning of your main function:
http://play.golang.org/p/DqnivLi1Z2
cwd, err := os.Getwd()
if err != nil {
log.Fatal("os.Getwd ", err)
}
log.Println("Current Directory", cwd)
files, err := ioutil.ReadDir(cwd)
if err != nil {
log.Fatal("ioutil.ReadDir", err)
}
for idx, finfo := range files {
log.Println(idx, " ", finfo.Name)
}
