可否支持CORS

[aston314]

Access to XMLHttpRequest at 'http://xxxxx.com/translate' from origin 'null' has been blocked by CORS policy: Request header field content-type is not allowed by Access-Control-Allow-Headers in preflight response.

这个问题不是很难解决，但这几天我暂时没有时间去处理，如果有人能够为此贡献那是最好的，如果没有的话，我会在之后的闲暇时间解决CORS，大概在一周内吧。

import express from 'express';
import bodyParser from 'body-parser';
import cors from 'cors'; // 引入 cors 模块
import { translate } from './translate.js';

const app = express();
const PORT = 9000;
const allowAlternative = true;

// 使用 CORS 中间件
app.use(cors());

app.use(bodyParser.json());

// 为了方便兼容多平台才这样写
app.post('/translate', async (req, res) => await post(req, res));
app.get('/', async (req, res) => await get(req, res));

async function post(req, res) {
const startTime = Date.now(); // 记录开始时间

// 检查请求方法和请求体
if (req.method !== 'POST' || !req.body || !req.body.text) {
const duration = Date.now() - startTime;
console.log([LOG] ${new Date().toISOString()} | 404 | ${duration}ms | POST "translate");
return res.status(404).json({
"code": 404,
"message": "Path not found"
});
}

// 判断是否备选翻译
if (!allowAlternative) alt_count = 0;
const { text, source_lang, target_lang, alt_count } = req.body;

try {
const result = await translate(text, source_lang, target_lang, alt_count);
const duration = Date.now() - startTime; // 计算处理时间
console.log([LOG] ${new Date().toISOString()} | 200 | ${duration}ms | POST "translate");

const responseData = {
  code: 200,
  data: result.text, // 取第一个翻译结果
  id: Math.floor(Math.random() * 10000000000), // 生成一个随机 ID
  method: 'Free',
  source_lang,
  target_lang,
  alternatives: result.alternatives
};

res.json(responseData);

} catch (error) {
const duration = Date.now() - startTime;
console.error([ERROR] ${new Date().toISOString()} | 500 | ${duration}ms | POST "translate" | ${error.message});
res.status(500).json({
code: 500,
message: 'Translation failed',
error: error.message
});
}
};

async function get(req, res) {
res.json({
code: 200,
message: "Welcome to the DeepL Free API. Please POST to '/translate'. Visit 'https://github.com/OwO-Network/DeepLX' and 'https://github.com/guobao2333/DeepLX-Serverless' for more information."
});
};

// 启动本地服务器
app.listen(PORT, () => {
console.log(Server is running on http://localhost:${PORT});
});

export { post, get };

需要安装 cors 模块
npm install cors

我实在看不懂你上面这一段到底在表达什么，看起来像是把代码复制了一份过来……如果你想说的能跟你的标题一样就好了
