GZipMiddleware (unzipping encoded requests)

Dear maintainers,

I am looking for the appropriate way to unzip clients requests which are gzip encoded. Looking at the GZipMiddleware it seems that it only zip responses but do not care about requests.

Thus I tried to do it at the dispatch level without success. I did something like:

@app.middleware("http")
async def dispatch(request, call_next):
    plain_body = gzip.decompress(request.body())
    request._body = plain_body  # I don't think it is the appropriate way
    response = await call_next(request)  # hangs here
    return response

I am not extremely familiar with the inner-working of starlette so I don’t know how to “push back in the queue” the decoded the request with the decoded body. If found no middlewares doing similar things.

Anyone can pinpoint me the appropriate way to do it ?

Thank you in advance for your help 😉

We’re not preventing anyone from developing a GZipMiddleware that handles unzipping requests. You’re welcome to do so as a third party package, and we’d happily link to it from the docs.
