我想通過填充它的Web表單並請求POST來將圖像上傳到ImageBam。如何繞過Python中的機械化「AmbiguityError」
我不太瞭解urllib2，httplib，多部分的東西。我正在嘗試使用MECHANIZE模塊 但我認爲它不應該太複雜，因爲它只是一個Web表單，我會填寫併發布它。
的頁面，上傳的形式是： http://www.imagebam.com/basic-upload
的形式，我試圖填補：
<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>
我也看到一個人創建使用Python應用程序; http://sourceforge.net/projects/pymguploader/files/pymguploader/2011-12-24/ 我想寫這樣的東西，但當然更基本。
無論如何，這是我的問題; 當我執行這些;
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")
一切正常，我認爲。
也
print a
給出了這樣的輸出：
<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])>>
>
但是當我
a["file[]"]=dosya
誤差;
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[]'
我該如何解決這個問題？
解決
解決方案：
a.add_file（dosya， 「文件名」，NR = 0）
該自動搜索類型=文件的輸入，並增加了我的文件到第一個（ NR = 0提供它）
新課題 後我發送POST數據（或I認爲它發送） 釷是頁面作爲迴應;

通常情況下，它是與圖像的鏈接等 出來後，上傳頁面，但我認爲這是一個動態的過程，因爲當我的頁面並沒有準備好鏈接。
我錯過了什麼嗎？因爲即使你不填寫表單上的輸入，如果你提交（）它，它會將你重定向到上傳頁面。
你可以嘗試使用select_control與nr = 0來選擇第一個文件？ – 2012-01-13 17:51:59

它看起來像一個dupl。但沒有解決辦法。 @Lennart，非常感謝你的回答，這很有效！ – gokcennurlu 2012-01-13 22:51:19
