When the URL address contains Chinese, or the parameters are Chinese, this is quite normal, but the URL as a parameter to pass the time (the most common callback), you need to put some Chinese or even '/' to do the code conversion.

First, UrlEncode

The Urllib library has a urlencode function that converts a key-value pair such as key-value into the format we want, and returns a string such as a=1&b=2, such as:

>>> FromUrllibImportUrlEncode>>> Data={... A: ,...  ' name ' :  ' Warcraft '  }>>> print urlencode (data) a=test&amp ; name=%c4%a7%< span class= "n" >ca%de          

What if you only want to convert a string to UrlEncode? Urllib provides another function: quote ()

>>> from urllib import quote>>> quote(‘魔兽‘)‘%C4%A7%CA%DE‘

Second, UrlDecode

When the string after the UrlEncode is passed over, the acceptance will decode the--urldecode. Urllib provides unquote () This function, can not urldecode ()!

>>> from  urllib import unquote>>> unquote('%c4%a7 %ca%de '\xc4\xa7\xca\xde'>>> print unquote('%c4%a7% Ca%de ') warcraft               

Iii. Discussion

When doing urldecode, see unquote () This function output, is corresponding to the Chinese code in the GBK, in contrast to the results of quote () is not difficult to find, the so-called UrlEncode is the string interchange GBK code, and then replace the \x to%. If your terminal is UTF8 encoded, then to turn the results into UTF8 output, otherwise garbled.

Functions such as UrlEncode (), UrlDecode () can be customized or rewritten according to the actual situation.
