[SOLVED] How do I make a variable in the requests payload for python?

How do I make a variable in the requests payload for python?

I have the following payload for the requests module in python and I want to make MAC and NAME a variable as I iterate through a csv of information? Is there a way to do this?

  payload = '''{
        "clients": [
            {
                "mac": MAC,
                "name": NAME
            },
        ],}'''

Solution

Hand-formatting JSON is error-prone. For example, the trailing commas were incorrect and the curly braces need to be doubled up for a f-string.

Instead, Use a Python object and serialize it with json.dumps:

import json

MAC = 'xxxxxxxxxxxx'
NAME = 'example'

payload = json.dumps({"clients": [{"mac": MAC, "name": NAME}]}, indent=2)

print(payload)

Output:

{
  "clients": [
    {
      "mac": "xxxxxxxxxxxx",
      "name": "example"
    }
  ]
}

Also, depending on what you are doing, are you sure you need a JSON string? For example, a get can be:

payload = {'key1': 'value1', 'key2': 'value2'}
r = requests.get('https://httpbin.org/get', params=payload)

or a put can be:

r = requests.put('https://httpbin.org/put', data={'key': 'value'})
