图一
原标题:image uploads in tornado web server [closed]

i m 试图获得一个简单的图像上载荷,投身于龙卷风。 这些数据都用文字文档进行细化,数据正在输入服务器,并提交给档案系统。 然而,当我试图上载双双双手文件时(具体地说,是jpeg或png),它就会腐败。 PNG的上载结果造成“PNG”错误,而“PNG”则被化成正文,“jpeg数据流不含任何图像”。 什么是错了?

python:

class FileUploadHandler(BaseHandler):
    def post(self):
    reg=self.get_argument( regid , None)
    self.write(dir(self.request.files[ myfile ][0]))
    if reg:
        reg=Registration(id=reg)
        f=open(ROOT_APP_PATH+ /static/clubfiles/{0}/{1}/{2} 
            .format(reg.club.id, reg.id, uuid()),  w )
        f.write(self.request.files[ myfile ][0][ body ])
        f.close()

html:

   <form    target=iframe 
            action="/do_file_upload/" 
            enctype="multipart/form-data; charset=utf-8"
            method="post">
        <input type=hidden name=regid value=${element.get_relevant_registration().id}>
        <input name=myfile type=file onchange="$(this).parent().submit()">
    </form>

龙多服务器在2008年运行,如果相关的话。

edit:水坝,简单固定。 i 需使用公开(姓名、轮)以双亲方式书写。 希望能帮助那些从山羊向座的人。
