推荐答案

通常，您可以使用Express(node.js)中的Response对象的API删除标头，但是，HTTP规范要求其中一些标头并且应该一直在那里.

Generally, you can use the API of the Response object in Express (node.js) to remove headers, however, some of them are required by the HTTP spec and should always be there.

Date标头是必需的.看到这里: https://stackoverflow.com/a/14490432/1801

The Date header is such a required one. See here: https://stackoverflow.com/a/14490432/1801

第一行( HTTP/1.1 200 OK )不是标头-它是HTTP协议的一部分，每个响应都应以此开头.否则，浏览器将不知道如何处理响应.

The first line (HTTP/1.1 200 OK) is not a header - it is part of the HTTP protocol and each response should start with it. Otherwise the browser wouldn't know what to do with the response.

如果要删除其他自定义标头，则可以这样做:

If you want to remove other custom headers, you can do it like this:

app.get('/test', function (req, res) {
    var body = "some body";
    res.removeHeader('Transfer-Encoding');
    res.removeHeader('X-Powered-By');
    res.end(body);
});
