使用JavaScript生成JSON时本地化字符串损坏的问题求助

问题背景 #

我有两个对象，一个存储英文字符串值，另一个存储对应本地化值。localeGenerator.js代码如下：

/*English Strings/*
const filteredKeys = {
        "Select a connection" : "Select a connection",
        "Script Viewer" : "Script Viewer",
        "Execution Script" : "Execution Script",
        "Workflows" : "Workflows",
        "Select Workflow" : "Select Workflow",
};

/*localized value with respect to English string*/
const translations = {
  "Saved Actions": "Actions enregistrées",
  "Select a connection": "Sélectionner une connexion",
  "Execution Script": "Exécution Script",
  "Close": "Fermer",
  "Workflows": "Workflows",
  "Select Workflow": "Sélectionner un workflow",
  "Clone": "Cloner"
 };

let outputFileJson = {};
let notFoundTranslatedValues = [];

for (element in filteredKeys) {
  if (element in filteredKeys) {
    if (translations[element] === undefined) notFoundTranslatedValues.push(element);
    outputFileJson[element] = translations[element];
  } else {
    notFoundTranslatedValues.push(element);
  }
}

执行命令 node .\localeGenerator.js > outputResult 生成outputResult JSON文件后，发现本地化字符串损坏，求解决办法。

修复方案 #

1. 缺失JSON输出逻辑 #

当前代码仅构建了结果对象，但未将其输出到控制台，导致重定向到文件时内容异常。需添加JSON格式化输出代码：

console.log(JSON.stringify(outputFileJson, null, 2));

2. 循环逻辑冗余且存在错误 #

for (element in filteredKeys)已经遍历filteredKeys的键，内部if (element in filteredKeys)判断完全多余；且当翻译不存在时，会给outputFileJson赋值undefined，导致JSON中出现无效的null值。优化后的循环：

for (const key of Object.keys(filteredKeys)) {
  const translated = translations[key];
  if (translated === undefined) {
    notFoundTranslatedValues.push(key);
    // 可选：若需要保留原英文作为默认值，取消下方注释
    // outputFileJson[key] = filteredKeys[key];
  } else {
    outputFileJson[key] = translated;
  }
}

3. 终端编码问题（Windows环境） #

Windows终端默认编码非UTF-8，会导致法语特殊字符（如é、è）损坏。可改用PowerShell命令指定UTF-8编码输出：

node .\localeGenerator.js | Out-File -Encoding UTF8 outputResult

完整修复代码 #

/*English Strings*/
const filteredKeys = {
        "Select a connection" : "Select a connection",
        "Script Viewer" : "Script Viewer",
        "Execution Script" : "Execution Script",
        "Workflows" : "Workflows",
        "Select Workflow" : "Select Workflow",
};

/*localized value with respect to English string*/
const translations = {
  "Saved Actions": "Actions enregistrées",
  "Select a connection": "Sélectionner une connexion",
  "Execution Script": "Exécution Script",
  "Close": "Fermer",
  "Workflows": "Workflows",
  "Select Workflow": "Sélectionner un workflow",
  "Clone": "Cloner"
 };

let outputFileJson = {};
let notFoundTranslatedValues = [];

// 优化循环逻辑
for (const key of Object.keys(filteredKeys)) {
  const translated = translations[key];
  if (translated === undefined) {
    notFoundTranslatedValues.push(key);
    // 可选：保留原英文作为 fallback
    // outputFileJson[key] = filteredKeys[key];
  } else {
    outputFileJson[key] = translated;
  }
}

// 输出格式化JSON
console.log(JSON.stringify(outputFileJson, null, 2));

// 可选：输出未找到翻译的字符串列表
// console.log("\n未找到翻译的字符串：", notFoundTranslatedValues);
