suggestions for API additions

Thanks for making this! I needed a quick tool to manipulate HTTP POST requests I had logged in Charles, and this was quite helpful.

When I used it, I needed to make a few changes. The first two are probably no-brainers to add, and I only wanted them to keep knowledge about the JSON structure from leaking out into my tool.

On the CharlesRequest class, I added

    def get_headers(self):
        return self.request_dict['request']['header']['headers']

    def get_body(self):
        return self.request_dict['request']['body']['text']

The other thing I needed was to build a session from a file-like object. I'm not sure I've thought that through carefully enough that you'll want to add it just the way I did, but here's how I changed the CharlesSession constructor:

    def __init__(self, request_list=list(), path=None, file=None):
        if file is not None:
            self._all_requests = [CharlesRequest(r) for r in json.load(file)]
        elif len(request_list) == 0 and path is not None:
            with open(path, 'r') as f:
                self._all_requests = [CharlesRequest(r) for r in json.load(f)]
        elif len(request_list) > 0 and path is None:
            self._all_requests = [CharlesRequest(r) for r in request_list]
        else:
            self.fail('only one initialization parameter should be specified')
        _assign_indexes(self._all_requests)

All my mods and my little tool are all available in my public repo under the same license as pycharles in case you find it interesting or useful.

I haven't used this enough and thought it through carefully enough to make it a pull request (and probably won't end up doing so) but it seemed worth sharing anyway.
