Hey all, just updating a little plugin that I had running on an old
version of Weewx and Python2
It seems some code that I was using to do the rest call has changed between
Python2 and 3, and Im seeing the following stack when the request is
called.
weewx[14173] ERROR weewx.restx: *** Traceback (most recent call last):
weewx[14173] ERROR weewx.restx: *** File

weewx[14173] ERROR weewx.restx: *** TypeError: POST data should be bytes,

The code I was using was the following....
def process_record(self, record, dbm):
r = self.get_record(record, dbm)
data = self.get_data(r)
if self.skip_upload:
loginf("skipping upload")
return
#logdbg('PR ---- using device_key: %s' % self.device_key)
#logdbg('PR ---- using server_url: %s' % self.server_url)
req = six.moves.urllib.request.Request(self.server_url, data)
req.get_method = lambda: 'POST'
req.add_header("User-Agent", "weewx/%s" % weewx.__version__)
auth_header = '%s:%s' % ('dev',self.device_key)
#update
str_to_bytes = auth_header.encode('ascii')
b64s = base64.b64encode(str_to_bytes)
req.add_header("Authorization", "Basic %s" % b64s)
#end update
req.add_header("Content-Type", "application/json")
self.post_with_retries(req)
It was working with Python2 version of Weewx. If anyone has some
thoughts on this, or an alternative way to make the rest call, it would
be much appreciated.
Cheers,
-Joe
