How to implement post parameter handling if you don't know its name?

Question

Python

I need to write a handler that accepts different post parameters that have different variable names all the time.

that is, the handler must add a phone number to the database, but it can come with both POST['phone'] and POST['telephone'], etc.
From my thoughts there are two ways. This is to store, for each field you expect, possible variable names. That is, I expect phone_number = ['telephone','phone'] for the example above. And see if there is such a variable in the data sent by POST, if not, then the second method is turned on, this is a search by pattern (regex). We search by the values ​​of the data sent by POST and thus calculate the variable name.

Are there more delicate, slender ways of implementation?

Answer 1

Well, there must be some common feature. If this is the substring "phone" or there - "phone" - then you can do something like this:

data1 = {'key': '1', 'phone': '2'}
data2 = {'key': '3', 'telephone': '4'}
data3 = {'key': '5', 'telePhone': '6'}
data4 = {'key': '7', 'PHONE': '8'}
data5 = {'key': '9', 'Телефон': '10'}

PATTERNS = ['phone', 'телефон']  # тут перечислить подстроки

getphone = lambda data:next(filter(lambda x: any([y in x.lower() for y in PATTERNS]), data.keys()))
print(data1[getphone(data1)])
print(data2[getphone(data2)])
print(data3[getphone(data3)])
print(data4[getphone(data4)])
print(data5[getphone(data5)])

# 4
# 6
