multipart/form-data and a generator...

[steve-osfda]

I used a generator as an argument to data for Content-Type application/json, and that worked fine.

The problem now is that I need to do this for multipart/form-data, and it appears to not support a generator.

• I tried files={'content': my_generator_func()} and got: a bytes-like object is required, not 'generator'; so it looks like it would have accepted a file descriptor, but not a generator.

• I then tried a generator for the data argument, and set the files argument to a form name and value: files={'encoding': (None, 'base64')} [I read you have to use the files argument to get requests to do multipart/form-data] For that I get the error "Streamed bodies and files are mutually exclusive".

• Just in case, I tried it different ways setting a header for Content-Type multipart/form-data, both with and without it [I had read that setting it yourself can mess up requests.] If I omitted it, it complained it was missing; and if I included it, I got the errors previously specified.

Is it possible to furnish a generator for multipart/form-data? If I have to, I will dump the stream into a file and pass a descriptor to the files argument; but seems that you would have furnished a way to use a generator since it is supported for Content-Type application/json
