提供动态生成的文件而不是 htm

Question

I'm completely new to twisted and need a little push forward. I'm looking for a way to serve a dynamically generated file other than htm page - for example csv file.

EDIT: It happened that while change of 'content-type' would suffice with csv file, what I needed was a change of 'content-disposition' of request:

request.responseHeaders.setRawHeaders('content-disposition', ['attachment; filename="file.csv"'])

Answer 1

设置正确的Content-type标头。

request.responseHeaders.setRawHeaders('content-type', ['text/csv'])

Answer 2

The basic idea how to do this is to generate HTTP response like this:

...
Content-Type: text/csv; charset=utf-8

1,2,3,4
...

I don't know whether you are familiar how does raw HTTP request look, but it consists of two major fields:

• header
• body (html)

And they are separated by \\r\\n\\r\\n . So you just have to send new Content-Type header (set to text/csv ) and then binary content instead of HTML.

In twisted it's apparently possible trough setHeader method.

Edit - additional HTTP info based on comment

You could take look at:

• HTTP architecture explained
• some HTTP request/response examples
• supported HTTP status codes
