web.py+xheditor+ ajaxfileupload+新浪sae图片上传

新浪sae是不能像本地一样,直接把上传图片写入硬盘的,只能用新浪自己的云储存.

这里分享一下,我写的基于web.py上传代码,编辑器使用的是xheditor, 缩略图上传使用的是ajaxfileupload.js

模板部分

        $.ajaxFileUpload

上传的调用的两个类

 

class upload:def POST(self):import cgi
        from common import upload
        cgi.maxlen =3*1024*1024# 3MBtry:
            i = web.input(filedata={})exceptValueError:return u"文件过大"

        path = upload(i.filedata)return json.dumps({"err":"","msg":"!"+path})class thumb_upload:def POST(self):import cgi
        from common import upload
        cgi.maxlen =3*1024*1024# 3MBtry:
            i = web.input(thumb_upload={})exceptValueError:return u"文件过大"

        path = upload(i.thumb_upload)return json.dumps({"err":"","msg": path})

 

 

实际上传类

 

def upload(myfile):import time
    import random
    import os

    data = time.strftime("%Y%m%d")
    ran = str(random.randint(0,9999999999))+'_'
    filepath = myfile.filename.replace('\\','/')
    filename = filepath.split('/')[-1]if'SERVER_SOFTWARE'in os.environ:#确定以下是在sae环境下import sae.storage
        from settings import domain

        new_file_name ='upload/'+ data +'/'+ ran + filename
        #写入
        s = sae.storage.Client()
        ob = sae.storage.Object(myfile.file.read())
        s.put(domain, new_file_name, ob)
        path ="http://"+ domain +"-"+ domain +".stor.sinaapp.com/"+ new_file_name
    else:from settings import upload_dir

        filedir = upload_dir +'/'+ data
        ifnot os.path.exists(filedir):
            os.mkdir(filedir)#创建文件夹

        new_file_name = filedir +'/'+ ran + filename
        #写入
        fout = open(new_file_name,'wb')
        fout.write(myfile.file.read())
        fout.close()
        path ='/static/upload/'+ data +'/'+ ran + filename

    return path

 

 

以上,大功告成.
