在練習urllib操作中，遇到了url中含有中文字元的問題。比如http://dotamax.com/，看下原始碼的話，上方的搜尋框的name=p，輸入內容點選搜尋以後，通過GET方法進行傳遞，比如我們搜尋”意“，url變為http://dotamax.com/search/?q=意。但是url中是不允許出現中文字元的，這時候就改用urllib.parse.quote方法對中文字元進行轉換。

url = "http://dotamax.com/"
search = "search/?q=" + urllib.parse.quote("意")
html = urllib.request.urlopen(url + search)
 

需要注意的是不能對整個url呼叫quote方法。

print(urllib.parse.quote("http://dotamax.com/search/?q=意"))

http%3A//dotamax.com/search/%3Fq%3D%E6%84%8F

但是還有更方便的方法：

import urllib.parse

b = b'/:?='
print(urllib.parse.quote("http://dotamax.com/search/?q=意", b))
 

http://dotamax.com/search/?q=%E6%84%8F

Help on function quote in module urllib.parse:

quote(string, safe='/', encoding=None, errors=None)
    quote('abc def') -> 'abc%20def'
    
    Each part of a URL, e.g. the path info, the query, etc., has a
    different set of reserved characters that must be quoted.
    
    RFC 2396 Uniform Resource Identifiers (URI): Generic Syntax lists
    the following reserved characters.
    
    reserved    = ";" | "/" | "?" | ":" | "@" | "&" | "=" | "+" |
                  "$" | ","
    
    Each of these characters is reserved in some component of a URL,
    but not necessarily in all of them.
    
    By default, the quote function is intended for quoting the path
    section of a URL.  Thus, it will not encode '/'.  This character
    is reserved, but in typical usage the quote function is being
    called on a path where the existing slash characters are used as
    reserved characters.
    
    string and safe may be either str or bytes objects. encoding must
    not be specified if string is a str.
    
    The optional encoding and errors parameters specify how to deal with
    non-ASCII characters, as accepted by the str.encode method.
    By default, encoding='utf-8' (characters are encoded with UTF-8), and
    errors='strict' (unsupported characters raise a UnicodeEncodeError).
