我按照以下指南介绍了如何使用HTML和CGI https://www.tutorialspoint.com/python3/python_cgi_programming.htm将文件上传到我的服务器。
它工作得很好但是，我需要用户一次添加大量文件。理想情况下，我希望他们按住“SHIFT”或“CTRL”并选择他们想要上传的文件。这可能吗？
这就是我的工作原理。
<!doctype html>
<html>
<head>
<title>testupload</title>
</head>
<body>
<form enctype="multipart/form-data"
action="logsupload.py" method="post">
<p>File: <input type="file" name="filename" /></p>
<p><input type="submit" value="Upload" /></p>
</form>
</body>
</html>
#!\Users\administrator\Python\Python36-32\python.exe -u
import cgi, os
import cgitb; cgitb.enable()
form = cgi.FieldStorage()
# Get filename here.
fileitem = form['filename']
print("""\
Content-Type: text/html\n
<html>
<body>
""")
# Test if the file was uploaded
if fileitem.filename:
# strip leading path from file name to avoid
# directory traversal attacks
fn = os.path.basename(fileitem.filename)
open('C:/testupload/' + fn, 'wb').write(fileitem.file.read())
print('The file "' + fn + '" was uploaded successfully')
else:
print("No file was uploaded")
print("""
<form name="pyform" method="GET" action="nextscript.py" >
Enter your favorite dog breed
<input type="text" name="breed"/>
<br>
<input type="submit" name="submit" value="Submit" />
</form>
""")
答案 0 :(得分：0)
这就是诀窍。
<form enctype="multipart/form-data" action="upload.py" method="post">
<p>File: <input type="file" name="filename" multiple=""/>
<p><input type="submit" value="Next" /></p>
</form>
import shutil
import cgi, os
print("""\
Content-Type: text/html\n
<html>
<body>
""")
directory = 'C:/tmp/'
form = cgi.FieldStorage()
fileitem = form['filename']
if 'filename' in form:
filefield = form['filename']
if not isinstance(filefield, list):
filefield = [filefield]
for fileitem in filefield:
if fileitem.filename:
fn = os.path.basename(fileitem.filename)
# save file
with open(directory + fn, 'wb') as f:
shutil.copyfileobj(fileitem.file, f)
print("""
</body>
</html>
""")
