替换多个JSON文件中的对象属性值

const fs = require('fs');

// 读取JSON文件并解析为对象
function readJSONFile(filePath) {
  const fileContent = fs.readFileSync(filePath, 'utf8');
  return JSON.parse(fileContent);
}

// 将对象转换为JSON字符串并写入文件
function writeJSONFile(filePath, data) {
  const jsonString = JSON.stringify(data, null, 2);
  fs.writeFileSync(filePath, jsonString, 'utf8');
}

// 替换属性值
function replacePropertyValue(obj, propertyName, oldValue, newValue) {
  for (let key in obj) {
    if (typeof obj[key] === 'object') {
      replacePropertyValue(obj[key], propertyName, oldValue, newValue); // 递归处理嵌套对象
    } else if (key === propertyName && obj[key] === oldValue) {
      obj[key] = newValue; // 替换属性值
    }
  }
}

// 替换多个JSON文件中的对象属性值
function replacePropertyValuesInJSONFiles(filePaths, propertyName, oldValue, newValue) {
  filePaths.forEach(filePath => {
    const json = readJSONFile(filePath);
    replacePropertyValue(json, propertyName, oldValue, newValue);
    writeJSONFile(filePath, json);
  });
}

// 示例用法
const filePaths = ['file1.json', 'file2.json', 'file3.json'];
const propertyName = 'name';
const oldValue = 'John';
const newValue = 'Jane';

replacePropertyValuesInJSONFiles(filePaths, propertyName, oldValue, newValue);
