不过在直接从mongodb中读取csv就杯具了:new-line character seen in unquoted field – do you need to open the file in universal-newline mode?
网上普遍的做法是,传递file的时候通过open(fpath,'rU')来控制文件的分段,pymongo天然好像不支持啊,后来看到这个哥们的 文章,建议用splitlines来提前分解掉文件内容,经测试确实好用,也还方便:
f = fs.get(fid) reader = DictReader(f.read().splitlines())
这尼玛竟然不一定要传file object的啊...
文档中的这句没有看到,着实让人吐血啊:

csvfile can be any object which supports the iterator protocol and returns a string each time its next() method is called — file objects and list objects are both suitable.
