问从文件中读取二进制字符串并保存为十六进制

EN

fs = require('fs')
fs.readFile('notes.txt', 'utf8', function (err,data) {
  if (err) {
    return console.log(err);
  }
  const buf = Buffer.from(data, 'ascii');
  //converting string into buffer
  var hexvalue = buf.toString('hex');
  //with buffer, convert it into hex
  console.log(hexvalue);
});

file = open("notes.txt","r")
str = file.readline()
str = str.encode('utf-8')
print (str.hex())

import binascii
f = open('path/to/file', 'rb').read()
hex_encoded = binascii.hexlify(f).decode('utf-8')
print(hex_encoded) #Prints hex stream as string
