从日志文件中的特定行中筛选出数字

import re

def extract_numbers_from_log(file_path):
    numbers = []
    with open(file_path, 'r') as file:
        for line in file:
            matches = re.findall(r'\d+', line)
            numbers.extend(matches)
    return numbers

# 示例用法
log_file_path = 'path/to/logfile.log'
numbers = extract_numbers_from_log(log_file_path)
print(numbers)

const fs = require('fs');

function extractNumbersFromLog(filePath) {
  const numbers = [];
  const fileContent = fs.readFileSync(filePath, 'utf-8');
  const lines = fileContent.split('\n');
  const regex = /\d+/g;
  
  for (const line of lines) {
    const matches = line.match(regex);
    if (matches) {
      numbers.push(...matches);
    }
  }
  
  return numbers;
}

// 示例用法
const logFilePath = 'path/to/logfile.log';
const numbers = extractNumbersFromLog(logFilePath);
console.log(numbers);
