Question

我想上传并从此网站获取结果。 http://cello.life.nctu.edu.tw/

我试过

from poster.encode import multipart_encode
from poster.streaminghttp import register_openers
import urllib2

register_openers()

params = ({"file": open("xaa", "r"),
       "seqtype": "prot",
       "species": "eu"})
datagen, headers = multipart_encode(params)

request = urllib2.Request("http://cello.life.nctu.edu.tw/cgi/main.cgi", datagen, headers)
print urllib2.urlopen(request).read()

但我收到了错误

  Traceback (most recent call last):
  File "client.py", line 9, in <module>
    a = opener.open("http://cello.life.nctu.edu.tw/cgi/main.cgi", params)
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 400, in open
    response = meth(req, response)
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 513, in http_response
    'http', request, response, code, msg, hdrs)
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 438, in error
    return self._call_chain(*args)
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 372, in _call_chain
    result = func(*args)
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 521, in http_error_default
    raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
urllib2.HTTPError: HTTP Error 500: Internal Server Error

我不知道这里有什么问题。有人能指出我吗？？谢谢。

顺便说一句。 xaa文件看起来像http://pastebin.com/7VK3vvwC

Answer 1

Error 500: Internal Server Error

这是服务器错误。换句话说，你的代码没有任何问题 - 只是这个页面出错了。

在python中使用POST上传文件。去哪儿看？
