Can't pass token in credentials config file (newline issue)

[lafrech]

Steps to reproduce:

Following instructions in https://v2.docs.influxdata.com/v2.0/reference/cli/influx/#usage, I set the token in my config file.

I get an error when trying to use it.

echo "8UJX0DXOqJV28U2nBSnrmYeZWD611G60_5AZkTS0tzIuNIZcF2OtCYAjiJgPMp8btaDSjlKBY1Jg==" > .influxdbv2/credentials

influx auth find
Error: Get http://localhost:9999/api/v2/authorizations: net/http: invalid header field value "Token KCB0Dshl2-8UJX0DXOqJV28U2nBSnrmYeZWD611G60_5AZkTS0tzIuNIZcF2OtCYAjiJgPMp8btaDSjlKBY1Jg==\n" for key Authorization.

However, it works by passing the token in the command line or in an environment variable.

influx auth find -t KCB0Dshl2-8UJX0DXOqJV28U2nBSnrmYeZWD611G60_5AZkTS0tzIuNIZcF2OtCYAjiJgPMp8btaDSjlKBY1Jg==

export INFLUX_TOKEN=KCB0Dshl2-8UJX0DXOqJV28U2nBSnrmYeZWD611G60_5AZkTS0tzIuNIZcF2OtCYAjiJgPMp8btaDSjlKBY1Jg==

From the error, it seems a \n is added at the end of the token. I don't see how to remove it. Maybe this is a user issue, but even so, influx should be able to remove it.

(The lines were not edited. This is a test instance in a VM not meant to be exposed so I don't mind the token appearing here.)

Environment info:

• Linux 4.19.0-6-amd64 x86_64
• InfluxDB 2.0.0-beta.1 (git: 128b9ee) build_date: 2020-01-15T14:50:20Z

@lafrech you should be able to use echo -n "token" > .influxdbv2/credentials

but we should also not throw that error. we will look into fixing that.

shouldn't be logging that token either I imagine 🤔

@lafrech I'm looking into this. I'm unable to reproduce on my local (darwin). It looks like you have the newline in the auth header. Try running the echo -n "token" > .influxdbv2/credentials which will trim the /n using the -n. In your error, you have the /n there which is coming from your credentials file.

Let me know if that doesn't fix things up. Otherwise, go on and close the issue and happy hacking 😃

[lafrech]

Thank you for your quick answers.

With the -n argument, it works fine.

echo -n "token" > .influxdbv2/credentials

However, without it, or if I just open the file with vim and paste the token, I get above error.

hexdump confirms there's that spurious 000a at the end of the file when it fails.

This could be qualified as a user issue (I should have known about -n) but I think Influx should be able to rip the \n off. I've never encountered this with other software reading config files. Therefore, I'm leaving this open. Feel free to close as wontfix.

@lafrech that's a great point. I'll throw something together to remedy that, great suggestion 👍

merged and sealed @lafrech 👍, thanks again for your patience and pro-activity 😃
