有什么方式可以将web页面封装成apk

async function getTk() {
  let tk = sessionStorage.getItem('tk');
  if (tk) {
    return tk;
  } else {
    try {
      const response = await fetch('https://api.example.com/tk');

      const data = await response.text();
      sessionStorage.setItem('tk', data);
      return data;
    } catch (error) {
      console.error('There was a problem with the fetch operation:', error);
    }
  }
}

// 遍历DOM树，将所有文本存储在一个JSON数组中
function getTextNodes(node, textNodes = []) {

    if (node.nodeValue.trim() !== '') {
      textNodes.push({
        text: node.nodeValue.trim(),
        translatedText: ''
      });
    }
  } else {
    for (let i = 0; i < node.childNodes.length; i++) {
      getTextNodes(node.childNodes[i], textNodes);
    }
  }
  return textNodes;
}

// 将JSON数组转换为文本，用于发送给服务器
function toJSONString(data) {
  return JSON.stringify(data, function(key, value) {
    return (typeof value === 'function') ? value.toString() : value;
  });
}

// 翻译文本并将结果应用于DOM树
async function translateText() {
  const textNodes = getTextNodes(document.body);
  const jsonData = toJSONString(textNodes);

  try {
    const response = await fetch('https://api.example.com/translate', {

// 获取Token值的方法
function getToken() {

// 使用示例

// 定义词典
const dictionary = [
  { english: 'hello', chinese: '你好' },
  { english: 'world', chinese: '世界' },
  { english: 'goodbye', chinese: '再见' },
];

// 定义翻译函数
async function translate(text) {
  // 在词典中查找
  const found = dictionary.find(entry => entry.english === text);
  if (found) {
    return found.chinese;
  }

  // 调用翻译 API
  const apiUrl = 'https://api.example.com/translate?text=' + encodeURIComponent(text);
  const response = await fetch(apiUrl);
  const result = await response.json();
  return result.translation;
}

// 使用示例
async function example() {
  const input = prompt('请输入要翻译的单词或短语：');
  const output = await translate(input);
  alert(output);
}
