Question

这是我想在Python中发布的表单：

  <FORM METHOD="POST"
    ACTION="http://www.speech.cs.cmu.edu/cgi-bin/tools/lmtool/run"
    ENCTYPE="multipart/form-data">
    <INPUT NAME="formtype" TYPE="HIDDEN" value="simple">

    <p><b>Upload a sentence corpus file</b>:<br> 
      <INPUT NAME="corpus" TYPE="FILE" SIZE=60 VALUE="empty">
    </p>

      <INPUT TYPE="submit" VALUE="COMPILE KNOWLEDGE BASE">
    </form>

我尝试了请求

import requests

url = "http://www.speech.cs.cmu.edu/cgi-bin/tools/lmtool/run"
#url = "http://httpbin.org/post"
files = {'file': open('testfile', 'rb')}
payload = {'NAME': 'fromtype', 'TYPE': 'HIDDEN', 'value': 'simple',
'NAME': 'corpus', 'TYPE': 'FILE', 'SIZE': '60', 'VALUE': 'empty'}
r = requests.post(url, data=payload)

print r.text

和回复

我需要为我正在处理的项目自动化此表单，请提供帮助！

Answer 1

可能还有其他错误，但您收到的错误信息足够清晰：

表格期望：

<INPUT NAME="formtype" ...>

你发送的内容：

'NAME': 'fromtype', ...

您看到 formtype 与 fromtype 之间存在差异？

根据Requests（More complicated POST requests，POST a Multipart-Encoded File）的文档，您的代码应为：

import requests

url = "http://www.speech.cs.cmu.edu/cgi-bin/tools/lmtool/run"
#url = "http://httpbin.org/post"
files = {'corpus': open('testfile', 'rb')}
payload = {'formtype': 'simple' }
r = requests.post(url, data=payload, files=files)

print r.text

如何使用Python发布此HTML表单？
