URL with hyphen char (-) generates "No host specified" error

[lantonioli]

Specifications

• Client Version: 1.37.0
• InfluxDB Version: 2.7.1
• Platform: Alpine Linux 3.1.1 with python version 3.8.10

Code sample to reproduce problem

import influxdb_client

config_host = 'local-server'

with influxdb_client.InfluxDBClient(url=f'{config_host}:8086', username='user', password='password', org='organization') as client:
      write_api = client.write_api(write_options=influxdb_client.client.write_api.SYNCHRONOUS)
      write_api.write('bucket/autogen', json_body, write_precision='ms')

Expected behavior

Write point successful

Actual behavior

write_api.write(...) returns an error "No host specified."

Additional info

If I change influxdb url to 'local.server' all goes fine.
It seems that hyphen character In url string is not supported by the lib.

Hi,

Is your config_host a full URI, like https://local-server or is it just the hostname? Have you tried both?

Thanks

Hi,
with config_host as full URI (i.e. http://local-server") connection is successful.

But if config_host doesn't contain hyphen char connection is successful in both the cases (http://local.server or local.server)

@lantonioli I would recommend you use the full URI with the protocol for a consistent behavior with the library. As there is a clear resolution it would be best to go that route, however if you do find something could be done better, please feel free to submit a PR and re-open this issue.

Thanks!
