함수 ReadAllText()

1 Bash[ | ]

str=`cat test.txt`
# John Smith

2 C[ | ]

char* buffer = 0;
long length;

FILE* fp = fopen("/etc/lsb-release", "rb");
fseek( fp, 0, SEEK_END );
length = ftell( fp );
fseek( fp, 0, SEEK_SET );
buffer = malloc( length );
fread( buffer, 1, length, fp );
fclose( fp );

printf("%s", buffer);

3 Cmd[ | ]

for /f "delims=" %a in ('type test.txt') do @set str=%a
echo %str%

4 C#[ | ]

string str = System.IO.File.ReadAllText(@"test.txt");
// John Smith

public static string file_get_contents(string filepath)
{
   try
   {
       if (filepath.ToLower().IndexOf("tp://") > 0)
       {
           System.Net.WebClient wc = new System.Net.WebClient();
           byte[] response = wc.DownloadData(filepath);
           return System.Text.Encoding.UTF8.GetString(response);
       }
       System.IO.StreamReader sr = new System.IO.StreamReader(filepath);
       string contents = sr.ReadToEnd();
       sr.Close();
       return contents;
   }
   catch
   {
       return "";
   }
}

5 Go[ | ]

Go ReadFile() 문서를 참고하십시오.

Go readAllText() 문서를 참고하십시오.

package main

import (
	"fmt"
	"os"
)

func main() {
	fileBytes, err := os.ReadFile("/etc/hosts")
	if err != nil {
		panic(err)
	}
	fmt.Println(string(fileBytes))
}

6 Java[ | ]

자바 Files.readAllBytes() 문서를 참고하십시오.

String content = new String(Files.readAllBytes(Paths.get("test.txt")));
System.out.println(content);

String content = new String(Files.readAllBytes(Paths.get(System.getProperty("user.dir"),"test.txt")));
System.out.println(content);

String content = "";
try {
	URI uri = getClass().getClassLoader().getResyntaxhighlight("test.txt").toURI();
	content = new String(Files.readAllBytes(Paths.get(uri)));
} catch (URISyntaxException | IOException e) { e.printStackTrace(); }
System.out.println( content );

7 Lua[ | ]

f = io.open('test.txt','rb')
content = f:read('*all')
f:close()
print( content )

8 PHP[ | ]

PHP file_get_contents() 문서를 참고하십시오.

$str = file_get_contents('test.txt');
// John Smith

9 Python[ | ]

f = open('name.txt')
print( f.read() )
f.close()

with open('name.txt') as f:
    content = f.read()
print( content )

10 Perl[ | ]

open my $in, '<', 'name.txt';
local $/;
my $contents = <$in>;
close($in);
print $contents;

11 Ruby[ | ]

str = open('test.txt').read
# John Smith
