Hi Andre,
I luckily find out a solution.
I change the json object to json string and then it works.So now the whole demo can run normally.
But how to do this job by odata model like you discribe in blog.(This is an additional question out of curiosity.)
It can deal with X-CSRF-Token itself and can match the data field which better than the way I use.
I try different way to build the post data,but all failed.
The code is like that I post in the question. This is the log:
Thank you~:)
Best regards,
Aria
