python版本是2.7，使用urllib2將文件推送至微信，在上傳文件時，碰到這樣一個問題：上傳未經壓縮的文本文件，可以成功；上傳經過壓縮的二進制文件，則提示編碼錯誤

代碼如下

def upload_tmpfile_old(self,filepath):

try:

#文件存在、文件可讀、文件大小小于19M

if not (os.path.isfile(filepath) and os.access(filepath,os.R_OK)

and os.path.getsize(filepath)<19922944):

return -1

boundary = '----------%s' % hex(int(time.time() * 1000))

data = []

data.append('--%s' % boundary)

fr = open(filepath, 'rb')

data.append('Content-Disposition: form-data; name="media"; filename="pickdump"')

data.append('Content-Type: application/octet-stream\r\n\r\n')

data.append(fr.read())

fr.close()

data.append('--%s--\r\n' % boundary)

http_body = '\r\n'.join(data)

print http_body

sendurl = "https://qyapi.weixin.qq.com/cgi-bin/media/upload?access_token=" + Token.gettoken() + "&type=file"

req = urllib2.Request(sendurl, data=http_body)

req.add_header('Content-Type', 'multipart/form-data; boundary=%s' % boundary)

req.add_header('Content-Length',len(http_body))

print req.headers

self.resp = urllib2.urlopen(req, timeout=5)

print self.resp.__dict__

print self.resp.read()

except:

logger.exception("上傳文件出現異常")

raise

if __name__ == '__main__':

uploadfile = wxRequest("WZ", '', '', "file", 1000002)

uploadfile.upload_tmpfile_old("/home/wz/12306.txt.zip")

報錯信息如下：

msg += message_body

UnicodeDecodeError: 'utf8' codec can't decode byte 0xb6 in position 149: invalid start byte

以前用python3，byte和str有明確的區分。這個功能由于版本問題，只能用python2，結果發現編碼各種坑啊。

壓縮文件本來就是一個二進制文件，不能被utf-8解碼也是正常的，不知道對于這個問題有沒有方法解決？

PS 以前用requests的時候,是把文件讀成bytes后，直接拼回body里面的，不知道這樣做在python2中應該如何寫？
