How to use urlencode function

The urlencode function is used to convert a data structure such as a dictionary or list into a URL-encoded string. Its main purpose is to encode data for transmission in a URL.

The following are some common uses of the urlencode function:

For encoding dictionary:

from urllib.parse import urlencode  
  
params = {  
    'param1': 'value1',  
    'param2': 'value2',  
    'param3': 'value3',  
}  
  
encoded_params = urlencode(params)  
  
print(encoded_params)  # 输出:param1=value1&param2=value2&param3=value3

For encoding list:

from urllib.parse import urlencode  
  
params = [('param1', 'value1'), ('param2', 'value2'), ('param3', 'value3')]  
  
encoded_params = urlencode(params)  
  
print(encoded_params)  # 输出:param1=value1&param2=value2&param3=value3

For encoding nesting List:

from urllib.parse import urlencode  
  
params = [('param1', 'value1'), ('param2', 'value2'), ('param3', ['value3-1', 'value3-2'])]  
  
encoded_params = urlencode(params)  
  
print(encoded_params)  # 输出:param1=value1&param2=value2&param3=value3-1&param3=value3-2

Specify delimiter:

By default, the urlencode function uses & as the delimiter between arguments. Additional delimiters can be specified using the do_plus parameter, for example using do_plus=True to use as delimiter:

from urllib.parse import urlencode  
  
params = {  
    'param1': 'value1',  
    'param2': 'value2',  
    'param3': 'value3',  
}  
  
encoded_params = urlencode(params, do_plus=True)  
  
print(encoded_params)  # 输出:param1=value1+param2=value2+param3=value3
