Python 文件上传不起作用，但dosen'；Don’我不会出错的

第一件事： -我正在使用Python2.7.7，因为cPanel已损坏。 -这是我为迎接挑战而写的博客

我想做的是，在

p\u image

字段中上传一个文件，并将其保存在

assets/images/post\u images/

中，然后将其命名为

p\u title+原始文件名（
p\u title
是帖子的名称）。
这是我目前的代码

filedata = data['p_image']
if filedata.file:
    with file(data.getvalue("p_title"), 'w') as outfile:
        outfile.write(filedata.file.read())
        post = "Success"

#start code stuff such as Content-type html \r\n\r\n don't worry it's the file upload not the print script   
print post

这是html脚本

<div class="create_post">
                <form method="GET" action="post_blog.py" enctype="multipart/form-data">
                    <input type="text" name="p_auth" placeholder="Enter Post Authenticator" />
                    <h2>Post preview</h2>
                    <input type="file" name="p_image"><br/>
                    <input type="text" name="p_title" placeholder="Title your post" /><br/>
                    <input type="text" name="p_date" placeholder="Date" /><br/>
                    <h1>Inside</h1>
                    <p>Title, date & preview image are to be placed here!<p>
                    <input type="text" name="p_desc" placeholder="Post Description" /><br/>
                    <input type="submit" value="Post!">
                </form>
            </div>

这给了我这个错误

<type 'exceptions.TypeError'>   Python 2.6.6: /usr/bin/python

A problem occurred in a Python script. Here is the sequence of function calls leading up to the error, in the order they occurred.
 /home/bearncat/*removed link due to privacy*/post_blog.py in ()
   39         post = str(filedata) + "\n"
   40         if filedata.file:
   41             with file(data.getvalue("p_image"), 'w') as outfile:
   42                 outfile.write(filedata.file.read())
   43                 post += "Success"
builtin file = <type 'file'>, data = FieldStorage(None, None, [FieldStorage('p_auth',..., ''), FieldStorage('p_desc_image_1', None, '')]), data.getvalue = <bound method FieldStorage.getvalue of FieldStor... ''), FieldStorage('p_desc_image_1', None, '')])>, outfile undefined

<type 'exceptions.TypeError'>: file() argument 1 must be encoded string without NULL bytes, not str
      args = ('file() argument 1 must be encoded string without NULL bytes, not str',)
      message = 'file() argument 1 must be encoded string without NULL bytes, not str' 

您是否检查了数据['p_image']本身是否包含数据？如果您为post_blog.py发布代码，这会有所帮助。另外，form方法真的是get吗？如果文件数据是get，则无法传递。因此，
数据[p_image]
确实包含类似于
.png
的内容。我将表单更改为POST，但现在，它给了我一个类型错误。@FranreySaycon完整代码粘贴在：。HTML代码位于：。快速编辑，python代码可以工作如果文件名中没有
data.getvalue（）
，它可以工作。data.getvalue（“p_图像”）可能有空字符\0。这是一个非常常见的错误。@FranreySaycon如何在不损坏文件的情况下删除它们？
