我正在尝试在提交之前对该字符串进行 urlencode。
queryString = 'eventName=' + evt.fields["eventName"] + '&' + 'eventDescription=' + evt.fields["eventDescription"];
urllib.quote_plussafe_string = urllib.quote_plus('string_of_characters_like_these:$#@=?%^Q^$')
#Value: 'string_of_characters_like_these%3A%24%23%40%3D%3F%25%5EQ%5E%24'
在 Python 3 中，
urlliburllib.parse.quote_plusparseimport urllib.parse
safe_string = urllib.parse.quote_plus(...)
urlencode()>>> import urllib
>>> f = { 'eventName' : 'myEvent', 'eventDescription' : 'cool event'}
>>> urllib.urlencode(f)
'eventName=myEvent&eventDescription=cool+event'
Python 3 或以上版本
urllib.parse.urlencode>>> urllib.parse.urlencode(f)
eventName=myEvent&eventDescription=cool+event
请注意，这确实 not 在常用意义上进行 url 编码（查看输出）。对于那个用途
urllib.parse.quote_plus尝试 requests 而不是 urllib，你不需要为 urlencode 而烦恼！
import requests
requests.get('http://youraddress.com', params=evt.fields)
编辑：
如果您需要 有序的名称-值对 或一个名称的多个值，请像这样设置参数：
params=[('name1','value11'), ('name1','value12'), ('name2','value21'), ...]
而不是使用字典。
以下是一个完整的解决方案，包括一些陷阱的处理方法。
### ********************
## 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
"""
试试这个：
urllib.pathname2url(stringToURLEncode)
urlencodequote_plus注意 urllib.urlencode 并不总能解决问题。问题是一些服务关心参数的顺序，当你创建字典时它会丢失。对于这种情况，正如 Ricky 所建议的那样，urllib.quote_plus 更好。
在 Python 3 中，这对我有用
import urllib
urllib.parse.quote(query)
供将来参考（例如：用于 python3）
>>> import urllib.request as req
>>> query = 'eventName=theEvent&eventDescription=testDesc'
>>> req.pathname2url(query)
>>> 'eventName%3DtheEvent%26eventDescription%3DtestDesc'
语法如下：
import urllib3
urllib3.request.urlencode({"user" : "john" })
为了在需要同时支持python 2和3的脚本/程序中使用，六个模块提供了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'
import urllib.parse
query = 'Hellö Wörld@Python'
urllib.parse.quote(query) // returns Hell%C3%B6%20W%C3%B6rld%40Python
另一件可能没有提到的事情是，
urllib.urlencode()Nonequote_plus对于 Python 3 urllib3 正常工作，您可以按照它的官方文档 如下使用：
import urllib3
http = urllib3.PoolManager()
response = http.request(
'GET',
'https://api.prylabs.net/eth/v1alpha1/beacon/attestations',
fields={ # here fields are the query params
'epoch': 1234,
'pageSize': pageSize
}
)
response = attestations.data.decode('UTF-8')
