I’m sharing this tip, as it took me way too long to find a simple solution online, and as most of my articles, as a reminder of how to do this again in the future. I have added username and passwords to my HTTP requests which also broken the scripts set in the EventGhost. Here is how EventGhost basic authentication in HTTP requests works.

EventGhost basic authentication in HTTP requests

I’m submitting my data to the NodeRED server, which is password protected and SSL certified. This means I have to now include the basic authentication (username, password) in my few requests. I have put together a few lines of codes that make it easy for you guys to use, and obvious to read.

To send the request – use the Python Script action and use the code below:

//HTTP POST request
import requests

username = "yourusername"                   ## your HTTP username
password = "secretpasswored"                ## your HTTP password
url = "https://192.168.1.xxx:1880/path"     ## NodeRED server address
data = {"light":1}                          ## some JSON formatted data

resp = requests.post(url, data, auth=(username, password))

The code is simple, but if you are using a laptop, consider DNS rather than the IP for the NodeRED server. If you want to know why or what can you do with it, imagine linking a request like this to a keyboard macro.  You can use this to trigger lights, events or send notifications to other devices.

EventGhost Global Variables

Because the details of my server have changed, I had to redo all my HTTP requests. I don’t want to do this each time something changes. I figured out that I can set the global variables in EventGhost on start. Let’s do this so should anything happen I can change the values in a single script.

On boot, I want EvenGhost to load the default values which will be used later on in each script. We can do this by placing a Python script with the sensitive details in AutoStart:

## Global Variable Names
user = "HTTP_username"      
passw = "HTTP_password"
nodeIP = "HTTP_ip"

## Global Variable Values
username = "your_user"
password = "your_pass"
IP = "YourNodeREDIP:1880"
## setting global attributes
setattr(eg.globals, user, username)
setattr(eg.globals, passw, password)
setattr(eg.globals, nodeIP, IP)

These values will be loaded when EventGhost starts and the same HTTP post from before will this time look like that:

import requests
#setting username and password
username = getattr(eg.globals, "HTTP_username")
password = getattr(eg.globals, "HTTP_password")

#composing a correct URL for HTTP
path = "/sonoff/relay/"
url = getattr(eg.globals, "HTTP_ip") + path

#adding data
data = {"light":0}

#sending a HTTP POST
resp = requests.post(url, data, auth=(username, password))

This way, if your IP or credentials change you have to modify only a single file.

I hope this tip on how EventGhost basic authentication in HTTP requests works will cut the googling time for you. If I can’t find a simple and well-explained answer within 3 pages of google searches it deserves an article. Even if it’s going to be a short one.
