蟒蛇：二进制数据HTTP PUT [英] python: HTTP PUT with binary data

问题描述

所以我适应的urllib2由<建议href=\"http://stackoverflow.com/questions/4511598/how-to-make-http-delete-method-using-urllib2\">answers另一个问题：

So I adapted urllib2 as suggested by answers to another question:

class HttpRequest(urllib2.Request):
  def __init__(self, *args, **kwargs):
    self._method = kwargs.pop('method', 'GET')
    urllib2.Request.__init__(self, *args, **kwargs)
  def get_method(self):
    return self._method

和它工作得很好了PUT与JSON：

and it works nicely for PUT with JSON:

req = HttpRequest(url=url, method='PUT', 
    data=json.dumps(metadata))
response = urllib2.urlopen(req)

但它失败，数据= 二进制数据（部分堆栈跟踪如下）：

but it fails with data= binary data (partial stacktrace below):

  File "c:\appl\python\2.7.2\lib\urllib2.py", line 126, in urlopen
    return _opener.open(url, data, timeout)
  File "c:\appl\python\2.7.2\lib\urllib2.py", line 394, in open
    response = self._open(req, data)
  File "c:\appl\python\2.7.2\lib\urllib2.py", line 412, in _open
    '_open', req)
  File "c:\appl\python\2.7.2\lib\urllib2.py", line 372, in _call_chain
    result = func(*args)
  File "c:\appl\python\2.7.2\lib\urllib2.py", line 1199, in http_open
    return self.do_open(httplib.HTTPConnection, req)
  File "c:\appl\python\2.7.2\lib\urllib2.py", line 1168, in do_open
    h.request(req.get_method(), req.get_selector(), req.data, headers)
  File "c:\appl\python\2.7.2\lib\httplib.py", line 955, in request
    self._send_request(method, url, body, headers)
  File "c:\appl\python\2.7.2\lib\httplib.py", line 989, in _send_request
    self.endheaders(body)
  File "c:\appl\python\2.7.2\lib\httplib.py", line 951, in endheaders
    self._send_output(message_body)
  File "c:\appl\python\2.7.2\lib\httplib.py", line 809, in _send_output
    msg += message_body
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 10: ordinal
 not in range(128)

有没有办法可以解决这个问题？

Is there a way I can fix this?

推荐答案

这是因为

数据应该是标准的应用程序/ x-WWW的形式urlen codeD格式的缓冲区。该urllib.urlen code（）函数的2元组的映射或序列，并以这种格式返回一个字符串。

data should be a buffer in the standard application/x-www-form-urlencoded format. The urllib.urlencode() function takes a mapping or sequence of 2-tuples and returns a string in this format.
