How to ensure that the "plus" does not disappear in the QueryDict?
I am trying to parse the received get-query into a dict:
from urllib.parse import quote_plus
my_non_safe_string = "test=1+1" # This example, the string can be anything. (in GET query format)
QueryDict(my_non_safe_string)
out: <QueryDict: {'test': ['1 1']}>
my_safe_string = quote_plus("test=1+1") # 'test%3D1%2B1'
out: <QueryDict: {'test=1+1': ['']}>
I would like to get the following result:
<QueryDict: {'test=1+1': ['1+1']}>
You need to percentage encode the plus, by use quote_plus you also encode the equal sign (=) and therefore the QueryDict can not parse it effectively:
my_safe_string = f'test={quote_plus("1+1")}'this produces:
>>> from urllib.parse import quote_plus
>>> my_safe_string = f'test={quote_plus("1+1")}'
>>> QueryDict(my_safe_string)
<QueryDict: {'test': ['1+1']}>
If it is unclear if the key contains any characters that should be escaped, you can use:
key = 'test'
value = '1+1'
my_safe_string = f'{ quote_plus(key) }={ quote_plus(value) }'How about this?
In [1]: from django.http import QueryDict
In [2]: from urllib.parse import quote_plus
In [3]: key = quote_plus("test=1+1")
In [4]: value = quote_plus("1+1")
In [5]: query_str = f"{key}={value}"
In [6]: QueryDict(query_str)
Out[6]: <QueryDict: {'test=1+1': ['1+1']}>
