[StarinschiAndrei]

Hello everybody,
I try to send a request to a web service based on the below description :
Can anybody help me? what is wrong?
Web Service URL (POST):
https://webservicesp.anaf.ro/PlatitorTvaRest/api/v3/ws/tva
Post Body:
[
{
"cui": _Numar_, "data":"_Data interogarii_"
},
{
"cui": _Numar_, "data":"_Data interogarii_"
}
]
Example :
Content-Type: application/json

[
{
"cui": 1234,
"data": "2015-02-14"
},
{
"cui": 5678,
"data": "2015-02-14"
}
]
My code :

Sub Submit_Action
    Dim j As HttpJob
    j.Initialize("",Me )
    j.PostMultipart("https://webservicesp.anaf.ro/PlatitorTvaRest/api/v3/ws/tva",CreateMap("cui": 39462862,"data":"2018-08-30"),Null)
    Wait For(j) JobDone(j As HttpJob)
    If j.Success Then
        Log(j.GetString)
    Else
        Log(j.ErrorMessage)     
    End If
    j.Release
End Sub

I receive the following error:

Has nothing to do with the data your posting (even though that is wrong). It has to do with SSL. The site seems to have a valid certificate, but Java does not seem to like it. What version of Java are you using? As to the other error (that has nothing to do with the error you are posting), a map is not a JSON structure.

Edit: See point# 7 in this link (near the bottom of the page): https://confluence.atlassian.com/kb...e-to-pkix-path-building-failed-779355358.html

Hi , I'm using java version "1.8.0_172". Thank you

 

[OliverA]

Latest 1.8.0 version is 181

 

[OliverA]

Well, even version 10 of Java does not like that certificate issued by CertSIGN. You may need to add it as per these instructions: http://onjavadev.com/?p=1197
