为了在需要同时支持python 2和3的脚本/程序中使用，six模块提供了quote和urlencode函数:

>>> from six.moves.urllib.parse import urlencode, quote
>>> data = {'some': 'query', 'for': 'encoding'}
>>> urlencode(data)
'some=query&for=encoding'
>>> url = '/some/url/with spaces and %;!<>&'
>>> quote(url)
'/some/url/with%20spaces%20and%20%25%3B%21%3C%3E%26'

供以后参考(例如:For python3)

>>> import urllib.request as req
>>> query = 'eventName=theEvent&eventDescription=testDesc'
>>> req.pathname2url(query)
>>> 'eventName%3DtheEvent%26eventDescription%3DtestDesc'

试试这个:

urllib.pathname2url(stringToURLEncode)

Urlencode不能工作，因为它只对字典有效。Quote_plus没有产生正确的输出。

注意urllib。Urlencode并不总是能做到这一点。问题在于，有些服务关心参数的顺序，而在创建字典时，这些顺序就会丢失。对于这种情况，使用urllib。正如Ricky建议的那样，quote_plus更好。

上下文

Python(版本2.7.2)

问题

您希望生成一个url编码的查询字符串。 您有一个包含名称-值对的字典或对象。 您希望能够控制名称-值对的输出顺序。

解决方案

urllib.urlencode urllib.quote_plus

陷阱

字典输出名称-值对的任意顺序 (请参见:为什么python对我的字典这样排序?) (请参见:为什么字典和集合中的顺序是任意的?) 处理不关心名称-值对顺序的情况 处理确实关心名称-值对顺序的情况 处理单个名称需要在所有名称-值对集中出现多次的情况

例子

以下是一个完整的解决方案，包括如何处理一些陷阱。

### ********************
## init python (version 2.7.2 )
import urllib

### ********************
## first setup a dictionary of name-value pairs
dict_name_value_pairs = {
  "bravo"   : "True != False",
  "alpha"   : "http://www.example.com",
  "charlie" : "hello world",
  "delta"   : "1234567 !@#$%^&*",
  "echo"    : "user@example.com",
  }

### ********************
## setup an exact ordering for the name-value pairs
ary_ordered_names = []
ary_ordered_names.append('alpha')
ary_ordered_names.append('bravo')
ary_ordered_names.append('charlie')
ary_ordered_names.append('delta')
ary_ordered_names.append('echo')

### ********************
## show the output results
if('NO we DO NOT care about the ordering of name-value pairs'):
  queryString  = urllib.urlencode(dict_name_value_pairs)
  print queryString 
  """
  echo=user%40example.com&bravo=True+%21%3D+False&delta=1234567+%21%40%23%24%25%5E%26%2A&charlie=hello+world&alpha=http%3A%2F%2Fwww.example.com
  """

if('YES we DO care about the ordering of name-value pairs'):
  queryString  = "&".join( [ item+'='+urllib.quote_plus(dict_name_value_pairs[item]) for item in ary_ordered_names ] )
  print queryString
  """
  alpha=http%3A%2F%2Fwww.example.com&bravo=True+%21%3D+False&charlie=hello+world&delta=1234567+%21%40%23%24%25%5E%26%2A&echo=user%40example.com
  """
