既然您说过您的特定应用程序是与python cgi模块一起使用的，那么快速的Google会举很多例子。这是第一个：
最小的http上传cgi（Python配方）（ snip ）
def save_uploaded_file (form_field, upload_dir): """This saves a file uploaded by an HTML form. The form_field is the name of the file input field from the form. For example, the following form_field would be "file_1":<input name="file_1" type="file"> The upload_dir is the directory where the file will be written. If no file was uploaded or if the field does not exist then this does nothing. """ form = cgi.FieldStorage() if not form.has_key(form_field): return fileitem = form[form_field] if not fileitem.file: return fout = file (os.path.join(upload_dir, fileitem.filename), 'wb') while 1: chunk = fileitem.file.read(100000) if not chunk: break fout.write (chunk) fout.close()
此代码将获取文件输入字段，该字段将是一个类似文件的对象。然后它将逐块读取到输出文件中。
2015年4月12 日 更新 ：根据评论，我已在此旧的activestate代码段的更新中添加了这些内容：
import shutildef save_uploaded_file (form_field, upload_dir): form = cgi.FieldStorage() if not form.has_key(form_field): return fileitem = form[form_field] if not fileitem.file: return outpath = os.path.join(upload_dir, fileitem.filename) with open(outpath, 'wb') as fout: shutil.copyfileobj(fileitem.file, fout, 100000)
