CUSession.GPA() no longer works

[AparaV]

Because of some very recent changes to myCUinfo system, this line attempts to convert some non-numeric characters to float. And the program breaks there.

I did some checking and this is what the webpage looks like now (5/26/2017):

And this is the source code for the radio buttons and the continue button (click to expand):

These actions are clearly JavaScript driven. Since (correct me if I'm wrong about this) requests cannot carry out JavaScript commands, it looks like we need to look at another package like selenium to do this for us.

Here is the website for quick access (you might need to login)

What do you think should be done?

I don't think we need to use selenium, but it might make life easier.

I think we can craft our own response here, following the format of the one they make when switching terms. This a bit convoluted so bear with me... 🙃

We can get the id of the term we want by looking at the value attribute of the element we want to 'click'.

<input
  ...
  class="PSRADIOBUTTON"
  id="SSR_DUMMY_RECV1$sels$4$$0"
  value="4">

Following the request (using Chrome's network tab) they make when you click the 'continue' button, we can see a few important details:

request headers

SSR_DUMMY_RECV1$sels$4$$0=4       <----------- the term id?

ptus_node=HRMS
ptus_workcenterid=
ptus_componenturl=https://isis-cs.prod.cu.edu/psp/csprod/UCB2/HRMS/c/SA_LEARNER_SERVICES.SSR_SSENRL_GRADE.GBL

So once we grab the term_id, then we need to craft a request resembling the one they make, but replacing

SSR_DUMMY_RECV1$sels$4$$0=4

with one of the form

SSR_DUMMY_RECV1$sels$<term_id>$$0=<term_id>

Hopefully this helps a little! @AparaV @719ben let me know what you guys think, maybe I can put together a fix for it next week if this seems like it'll work

[AparaV]

@mguida22 I think this fix will definitely work. Thanks for the quick reply!

@AparaV just as a general rule for this repo, nothing should be done using anything other than requests. Every request can and should be traced back, even if called by javascript. 😃
Disabling javascript in the browser or using an ad blocker that lists out requests is a great way to figure out the underlying HTTP request.

[AparaV]

@719ben got it! It didn't strike me to track down the HTTP request earlier, which was why I suggested using selenium.
I'll remember that (use only requests) next time!
