Multiple values for a key in parameter for get request

I am facing an issue where i need to send multiple values to parameters in the get response.

For example 

API is URL =https://localhost:9090?id=1&department=hr

Now in id I want to send 1,2,3,4 in a single request and I did like 

PARAMS = {'id': [1,2,3,4],'department'='hr'}

r = requests.get(url = URL, params = PARAMS)

It is not still giving the desired response as it is showing value for only id =4. Can anybody please help me with this?

This is most likely a server-side issue. Check whether the server is parsing the id field as intended or not. It would be much better if you could post the server code where the id field is being parsed.

When given a sequence, requests duplicates the key as you can see in the example from the official documentations.

>>> payload = {'key1': 'value1', 'key2': ['value2', 'value3']}

>>> r = requests.get('https://httpbin.org/get', params=payload)
>>> print(r.url)
https://httpbin.org/get?key1=value1&key2=value2&key2=value3

note key2=value2 and key2=value3, that's the standard encoding for multiple values (there are others e.g. comma or semicolon-separated values, or "magic" key names postfixed with [] as in PHP).

However depending on your server-side framework that may require using special APIs to get the values as lists, otherwise you might get just the first or just the last because the querystring is interpreted as a 1:1 dict (here you only get the last one).

So your solutions are:

  1. fix the server side, use whatever the proper API is to get multiple values for a key
  2. or define your own encoding for multi-valued query strings and use that explicitly when performing the request (and when parsing it on the server-side unless the framework has built-in support for that encoding)

Normally strings are send back and forth. In this case you may try:

PARAMS = {'id': '1,2,3,4','department' : 'hr'}

At server side you need to decode ID be using id.split(','). Then you get the four independent values again.
