在Express Node.js中禁用etag标头 [英] Disable etag Header in Express Node.js

问题描述

我们需要从Node.js Express应用程序中的所有HTTP响应中删除 etag 标头.我们有一个用Express编写的Web服务API，当我们发送etag时，客户端会看到意外的结果，而客户端会发回 if-none-match 标头.

我们尝试了 app.disable('etag')和 res.removeHeader('etag')，但均无效；该应用会发送标头，无论如何.

在所有响应中还有其他禁用此标头的方法吗?

解决方案

app.disable('etag')现在应该可以正常工作了，已经合并了一个拉取请求来处理此问题:

更新:正如Bigood在评论中指出的，新的处理方式如下:

  app.set('etag'，false);//关 

版本3.9.0中发生了更改: https://github.com/strongloop/express/releases/tag/3.9.0

有关设置etag的更多选项，请在此处查看4.x文档: http://expressjs.com/4x/api.html#app.set

We have a need to remove the etag header from all HTTP responses in our Node.js Express application. We have a web services API written in Express where unexpected results are seen at the client when we send etags and the client sends back the if-none-match header.

We've tried app.disable('etag') and res.removeHeader('etag'), but neither work; the app sends the header regardless.

Is there any other means of disabling this header in all responses?

解决方案

app.disable('etag') should work now, there has been a pull request merged to deal with this:

https://github.com/visionmedia/express/commit/610e172fcf9306bd5812bb2bae8904c23e0e8043

UPDATE: as Bigood pointed out in the comments the new way of doing things is the following

app.set('etag', false); // turn off

Change occured with version 3.9.0: https://github.com/strongloop/express/releases/tag/3.9.0

For more options on setting the etag check the 4.x docs here: http://expressjs.com/4x/api.html#app.set
