Google Appengine Python Web Upload File And Read The Content

I'm new at Python AND AppEngine, so maybe my question is basic but I've searched it for hours... So, I'm using Google AppEngine with python and HTML... So in my htlm file I have

Solution 1:

You can use cgi.FieldStorage() to upload a file < 32 megabytes. But you have to send the form as enctype="multipart/form-data"

<formaction="/upload"enctype="multipart/form-data"method="post"><div><inputtype="file"name="file"/></div><div><inputtype="submit"value="Upload"></div></form>

The post method in the /upload webapp2 request handler:

defpost(self):

    field_storage = self.request.POST.get("file", None)
    ifisinstance(field_storage, cgi.FieldStorage):
        file_name = field_storage.filename
        file_data = field_storage.file.read())
        ..... 

    else:
        logging.error('Upload failed')

Example taken from this gist

Solution 2:

Try this:

fileitem = self.request.POST['file']

If you want to store the file I would look into uploading it straight to Blob store first then process it as needed.
