Node.js/Express-如何设置响应字符编码?

问题描述：

说我明白了

app.get('/json', function(req, res) {
    res.set({
        'content-type': 'application/json'
    }).send('{"status": "0"}');
});

我正在尝试以UTF-8格式发送响应，但没有成功:

I'm trying to send the response as UTF-8 with the following with no success:

app.get('/json', function(req, res) {
    // From Node.js Official Doc
    // http://nodejs.org/api/http.html#http_http_request_options_callback
    res.setEncoding('utf8');

    res.set({
        'content-type': 'application/json'
    }).send('{"status": "0"}');
});

在Express中设置字符编码的正确方法是什么?

What is the correct way to set character encoding in Express?

答

使用res.charset: http ://expressjs.com/api.html#res.charset

Use res.charset: http://expressjs.com/api.html#res.charset

res.charset = 'value';
res.send('some html');
// => Content-Type: text/html; charset=value

但是，JSON默认情况下为UTF-8，因此您无需进行任何设置.

However, JSON is UTF-8 by default so you don't need to set anything.
