最近在处理服务器接口的时候，需要使用`Python`模拟发送表单数据到服务器，搜索了一下，找到如下例子：
# encoding=utf8
import urllib
import urllib2
import httplib
import os
HOST = 'xx.xx.xx.xx'
PORT = 8000
P_ID = xx
U_NAME = 'xxx'
API_KEY = 'xxx'
API_SEC = 'xxx'
UP_APK = xx
def sign(src, key):
HEX_CHARS = [ '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f' ]
from hashlib import sha1
import hmac
hashed = hmac.new(key, src, sha1)
sv = str(hashed.digest())
ret = ''
for b in bytearray(sv):
bite = b & 0xff
ret += HEX_CHARS[ bite >> 4 ]
ret += HEX_CHARS[ bite & 0xf ]
return ret
def encode_multipart_formdata(fields, files):
"""
fields is a sequence of (name, value) elements for regular form fields.
files is a sequence of (name, filename, value) elements for data to be uploaded as files

CRLF = '\r\n'
L = []
for (key, value) in fields:
L.append('--' + BOUNDARY)
L.append('Content-Disposition: form-data; name="%s"' % key)
L.append('')

return mimetypes.guess_type(filename)[0] or 'application/octet-stream'

req.add_header('Content-Type', 'multipart/form-data; boundary='+boundary)
resp = urllib2.urlopen(req, body)
res = resp.read()
print res
if __name__=='__main__':
