使用xls2db

Question

我希望从瓶上传中获取xlsx文件并将文件发送到xls2db模块以填充sqlite数据库，但我似乎没有正确传递文件。 ＃

     @route('/',method="GET")   # Select the xls sheet from this route
def testRoute():
    return ('''</br>
           <h1> Select the spreadsheet</h1>
           <form action="/upload" method="post" enctype="multipart/form-data">
            <input type="text" name="name" />
            <input type="file" name="data" />

            <input type="submit"/>
       </form>  ''')


@route('/upload', method='POST')
def do_upload():
    name = request.forms.name
    data = request.files.data
    if name and data and data.file:
        raw = data.file.read() # This is dangerous for big files
        filename = data.filename
        #return "Hello %s! You uploaded %s (%d bytes)." % (name,   filename, len(raw))
        upload_xls(raw, filename)

连接到数据库删除表（如果存在）并将xls表转换为sqlite数据库

def upload_xls(raw, filename):
    conn = sqlite.connect("test_db.sqlite")
    cur = conn.cursor()
    f = filename
    data = raw
    cur.execute("DROP TABLE IF EXISTS Requests;")
    cur.execute("DROP TABLE IF EXISTS Complaints;")
    xls2db(data , "test_db.db")
    redirect("/work")

更新 - 我现在收到此错误。

我可以上传文件，我现在可以在服务器上看到它，但是当我将它传递给函数时，它会报告它是空的。

    @route('/upload', method='POST')
    def do_upload():
        data = request.files.upload
        upload = request.files.get('upload')
        name, ext = os.path.splitext(data.filename)
        #check the file is an excel file
        if ext not in ( '.xls', '.xlsx'):
            return "File extension not allowed."

            save_path = "/home/mcslo/mysite".encode("utf-8")
            file_path= "{path}/{file}".format(path=save_path,        file=data.filename)
            raw = data.file.read() # This is dangerous for big file

           open_file = open(file_path, 'w')
           open_file.write(raw)
           open_file.close
           upload_xls(file_path)


    def upload_xls(file_name):
file_name = file_name
conn = sqlite.connect("test_db.sqlite")
cur = conn.cursor()
cur.execute("DROP TABLE IF EXISTS Requests;")
cur.execute("DROP TABLE IF EXISTS Complaints;")
xls2db(file_name, "test_db.db")
redirect("/work")
