python - 如何在 Python 中绕过 Mechanize "AmbiguityError"

我正在尝试通过填写网络表单并请求 POST 将图像上传到 ImageBam。

我不太了解 urllib2、httplib、多部分的东西。我正在尝试使用 MECHANIZE 模块但我认为它不应该太复杂，因为它只是一个网络表单，我会填写并发布。

页面，其中上传表单是: http://www.imagebam.com/basic-upload

我要填写的表格:

<form name='form' id='form' enctype="multipart/form-data" method="post" action="/sys/upload/save">


    <table align="center">
        <tr>
            <td>
                01: <input type="file" name="file[]" size="30"><br>
                02: <input type="file" name="file[]" size="30"><br>
                03: <input type="file" name="file[]" size="30"><br>
                04: <input type="file" name="file[]" size="30"><br>
                05: <input type="file" name="file[]" size="30"><br>

我还看到有人用 python 创建了一个应用程序； http://sourceforge.net/projects/pymguploader/files/pymguploader/2011-12-24/ 我想写类似的东西，但当然更基础。

无论如何，这是我的问题；当我执行这些时；

import mechanize
a=mechanize.Browser()
a.open("http://www.imagebam.com/basic-upload")
forms=mechanize.ParseResponse(response)
a.select_form(nr=0)
dosya=open("file path...","r")

我认为一切正常。

还有

print a

给出这个输出:

<Browser visiting http://www.imagebam.com/basic-upload
 selected form:
 <form POST http://www.imagebam.com/sys/upload/save multipart/form-data
  <FileControl(file[]=<No files added>)>
  <FileControl(file[]=<No files added>)>
  <FileControl(file[]=<No files added>)>
  <FileControl(file[]=<No files added>)>
  <SelectControl(content_type=[*x, 1, 0])>
  <SelectControl(thumb_size=[*100, 150, 180, 250, 300, 350])>
  <SelectControl(thumb_aspect_ratio=[crop, *resize])>
  <SelectControl(thumb_file_type=[gif, *jpg])>
  <CheckboxControl(thumb_info=[1])>
  <CheckboxControl(gallery_options=[*1])>>
>

但是当我

a["file[]"]=dosya

错误是；

Traceback (most recent call last):
  File "<pyshell#46>", line 1, in <module>
    a["file[]"]=dosya
  File "build\bdist.win32\egg\mechanize\_form.py", line 2780, in __setitem__
    control = self.find_control(name)
  File "build\bdist.win32\egg\mechanize\_form.py", line 3101, in find_control
    return self._find_control(name, type, kind, id, label, predicate, nr)
  File "build\bdist.win32\egg\mechanize\_form.py", line 3183, in _find_control
    raise AmbiguityError("more than one control matching "+description)
AmbiguityError: more than one control matching name 'file[]'

我该如何解决这个问题？

已解决

解决方法:

a.add_file(dosya,"文件名",nr=0)

自动搜索 type=file 输入并将我的文件添加到第一个(nr=0 提供)

新问题 在我发送 POST 数据后(或者我认为它发送了) 此页面作为回应；

一般情况下，上传后的页面会出现图片的链接等。但我认为这是一个动态过程，因为当我得到页面时链接还没有准备好。

我错过了什么吗？因为即使你不填写表单上的输入，如果你提交()它，它会将你重定向到上传后的页面..

最佳答案

同时使用 select_control() 和 nr=0 来选择第一个文件。
