Reading file from stdin does not work

[jaywor1]

Problem Description

In option rfile - is an invalid input

mitmweb

root@mitmweb-01:~# tail -f /var/log/mitmproxy/dump-merged.har | mitmweb --rfile - -n
tail: /var/log/mitmproxy/dump-merged.har: file truncated

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "mitmproxy/addons/readfile.py", line 71, in doread
  File "mitmproxy/addons/readfile.py", line 67, in load_flows_from_path

root@mitmweb-01:~# 

mitmproxy

Really mess-ups terminal and i get this error

Invalid filter expression: 'on": "1.1"'

I tested the file running it with a -r option and it normally loads the file.

Steps to reproduce the behavior:

1. tail -f /var/log/mitmproxy/dump-merged.har | mitmweb --rfile - -n

We're currently using the ReadFileStdin addon for mitmdump only, but I think we can enable it for mitmweb as well. For mitmproxy it won't work because we need stdin for user input.

Contributions welcome!

Could you enable it please 🙏 I don't really know how and where (in the source code).

That makes sense :D, fortunately I just need mitmweb
