VCR's representation of a request.
|
|
|
|
There is a weird quirk in HTTP. You can send the same header twice. For
|
|
this reason, headers are represented by a dict, with lists as the values.
|
|
However, it appears that HTTPlib is completely incapable of sending the
|
|
same header twice. This puts me in a weird position: I want to be able to
|
|
accurately represent HTTP headers in cassettes, but I don't want the extra
|
|
step of always having to do [0] in the general case, i.e.
|
|
request.headers['key'][0]
|
|
|
|
In addition, some servers sometimes send the same header more than once,
|
|
and httplib *can* deal with this situation.
|
|
|
|
Futhermore, I wanted to keep the request and response cassette format as
|
|
similar as possible.
|
|
|
|
For this reason, in cassettes I keep a dict with lists as keys, but once
|
|
deserialized into VCR, I keep them as plain, naked dicts.
