First attempt at Python Rest Get and Post to Mango

  • [](Uploading 100%)

    I'm new to Mango so my apologies for any 'school boy errors'. However I've spent the last couple of days writing a Python script to update a data point in Mango.

    I know that the point has been correctly enabled in Mango as I've been able to write to it from a remote machine via swagger :- URL//swagger/index.html#!/point-values/putPointValue

    I've also been able to get the users and sources data from Mango via my script. Please see attached. However were I'm falling down is the PUT. I notices that when I ran Wireshark and inspected the HTTP packet the formation of the cookie is slightly different between the putPointValue undate via Swagger and my Python script.

    I'm therefore uncertain if I've returning the cookie correctly to Mango (I started splitting out and reforming the cookie but this didn't work) or whether my JSON transfer is wrong. I'd assumed the JSON transfer was indentical in all cases.

    Any advise is highly appreciated!

  • Hi Rob,

    I'm wondering if you need to also be updating the X-Xsrf-Token header in your Rest_cookie_up_date method.

  • I just noticed you'll also need to remove your Content-Length header. I would have expected it to handle that for you in making the post() call.
