Stress test with probobuf format?

[NingLu]

We want to perform stress test on a http api with pb format, but, how to send http request in protobuf format by locust(instead, jmeter supports pb format) .

Is this the same with uploading file?
`files = {
'image': open('sample.jpg', 'rb'),
}

r = requests.post('http://localhost:5000/', files=files)`

As far as I know, protobuf is just a format for serializing/deserializing structured data - with existing libraries for python - so there shouldn't be any problem using it with Locust.

Exactly how depends on how the server expects the data to get transfered. If it expects it to be transfered as a multipart file upload you would use the files keyword argument (http://docs.python-requests.org/en/master/user/quickstart/#post-a-multipart-encoded-file). However, if I would guess, I would think that it's more likely that the data were to be transfered as raw data in the POST body:

self.client.post("/some/url", data=my_protobuf_data)
