Also another one with binary data post almost identical:




None of them are able to submit the files, just to be clear about the data format Im sending:

code[] ---> "[{\"filename\":\"main.cpp\",\"content\":\"I2luY2x1ZGUgPGlvc3RyZWFtPg0KI2luY2x1ZGUgPHN0ZGlvLmg+DQoNCnVzaW5nIG5hbWVzcGFjZSBzdGQ7DQoNCmludCBtYWluKCkNCnsNCiAgICBTdHJpbmcgbm9tYnJlPSJwZWRybyI7DQoJaW50IHZhbD0xLHZhMj0xMCx0b3RhbD0wOw0KCXRvdGFsPXZhbCt2YWwyOw0KCQ0KCQ0KICAgIHJldHVybiAwOw0KfQ0K\"}]"

shortname ---> The problem ddbb shortname value previously recovered with the "problems GET method of the API REST"

langid---> The language id value previously recovered with the "problems GET method of the API REST" (Ex: cpp)

contest ---> We have tried both contestId and contest_short_name. Im not sure wich one should be sent.

My last question is: Is the teamId necessary for the post?


We would thank any of your comments to finish this amazing program!!!

Thanks in advance
