Parsing HAR does not always show the correct status code (200 instead of 4xx)

[android-t709]

I'm using mitmproxy2swagger 0.13.0 to parse .har files generated by HTTP toolkit. I noticed that all the API endpoints showed 200 OK in the examples.
This seems to be because the code tries to parse the response as json (or msgpack)

mitmproxy2swagger/mitmproxy2swagger/mitmproxy2swagger.py

Lines 291 to 293 in d9abbb5

	response_body = req.get_response_body()
	if response_body is not None:
	# try parsing the response as json

get_response_body is often

mitmproxy2swagger/mitmproxy2swagger/har_capture_reader.py

Line 104 in d9abbb5

return self.flow["response"]["content"]["text"]

I tested this also with chrome, to get 404/400 codes in a .har.
Anyway, when the response body isn't json, the default response code of 200 is given. This happened a few times on 400 Bad Request on an API I was testing.
I'm not sure if this works differently with mitmproxy vs chrome, and this certainly isn't a priority for me. I just thought it was worth noting because it tripped me up a little.
