var app = express();
app.configure(function () {
app.use(express.logger('dev'));
app.use(express.bodyParser());
});
app.get('/drivers', driver.findAll);
app.listen(3000);

Hook into you response generator or create a middleware that does the following:
连接到您的响应生成器或创建一个执行以下操作的中间件：
res.header("Content-Type", "application/json; charset=utf-8");
Otherwise the browser displays the content in his favorite encoding.
否则浏览器以他喜欢的编码显示内容。
If this doesn't help you DB is probably in the wrong encoding.
如果这对您没有帮助，则 DB 可能处于错误的编码中。
Edit:Since the answer is nearly 5 years old, the API has changed. For current node.js versions use:
编辑：由于答案已有近 5 年的历史，因此 API 发生了变化。对于当前的 node.js 版本，请使用：
res.setHeader("Content-Type", "application/json; charset=utf-8");

I can't solve this problem with setting content type. I solved this problem with encode function.
我无法通过设置内容类型来解决这个问题。我用编码功能解决了这个问题。
res.cookie('someCookie', someCookie, {
encode: c => c,
});
For more information: express cookie
