appengine：解析上传文件中的csv数据 [英] appengine: parse a csv data in uploaded file

问题描述

是否有任何模块或包可以帮助解析appengine中已上传的csv文件中的csv内容。试图在python中使用csv包。但它只能解析文件系统中的文件，但不能数据..
http：// docs.python.org/library/csv.html

Are there any modules or packages which help parsing csv content from a uploaded csv file in appengine. tried using the csv package in python. but it could parse only files in file system but could not data.. http://docs.python.org/library/csv.html

推荐答案

但它可以仅解析文件
系统中的文件，但不能数据

but it could parse only files in file system but could not data

否， csv.reader 接受任何支持逐行迭代的对象。假设cgi.FieldStorage支持它，并且假设你发布了一个名为file的文件，你应该能够这样做：

No, csv.reader accepts any object that supports line-by-line iteration. Assuming cgi.FieldStorage supports it, and assuming you've posted a file named "file", you should be able to do this:

import csv
for row in csv.reader(self.request.POST['file']):
  # process row
