What is the HTTP "content-type" to use when returning a blob of bytes in response to a client's GET request?
In this case, the information payload is an object serialized using Python's Pickle library.
回答1:
You should use application/octet-stream.
回答2:
You should use the proper mime type:
application/python-pickle
This is the de-facto standard (this mean: it is not application/pickle or application/pickle-python).
RFC2046 states:
4.5.3. Other Application Subtypes It is expected that many other subtypes of "application" will be defined in the future. MIME implementations must at a minimum treat any unrecognized subtypes as being equivalent to "application/octet- stream".
So, to a non-pickle-aware system, the stream will look like any other octet-stream (you are not doing anything which will break existing apps), but to a pickle-aware system this is vital information.
