Uploading Files in webapp2/GAE

Question

I need to upload and process a CSV file from a form in a Google App Engine application based on Webapp2 (Python) I understand I could use blobstore to temporary store the file but I am curious to know if there is a way to process the file without having to store it at all.

Accepted Answer

The content of uploaded files is in `self.request.POST` in your handler, so you can get that content (assuming e.g the field for the uploaded file is named `'foo'`) with e.g

```
content = self.request.POST.multi['foo'].file.read()
```

So now you have the content as a string -- process it as you wish. This does of course assume the thing will fit in memory (no multi-megabyte uploads!-)...
