elitevenkat · Aug 21, 2022

hi I am trying to post json data using poststring method. It is returning always as false and the poststring method is not hitting the url at all.(ResponseError. Reason: , Response: )

However when tested from postman it works fine. Kindly help me in solving the issue.

B4X:

  B4A
        Main.cLocalIp="https://dapiserver.herokuapp.com"
        j2.PostString(Main.cLocalIp & "/neworder", "") 
        j2.GetRequest.SetHeader("order", ord)    '  ord is a  map
        j2.GetRequest.SetHeader("items", s)    ' s is a map
        j2.GetRequest.SetContentType("application/json")
      
        Wait For (j2) JobDone(j2 As HttpJob)
 
       If j2.Success Then
            Log(j2.GetString)
            'log("accepted " & j.GetString)            
        Else          
            Log(j2.ErrorMessage)
        End If
        j2.Release

the getmethod https://dapiserver.herokuapp.com/12345/orders?token=1000 is working fine

    j2.GetRequest.SetHeader("Content-Type", "application/json")
        
    Wait For (j2) JobDone(j2 As HttpJob)   ' ---- works fine

I think you should add the maps inside the poststring parameter instead of sending them as header.

B4X:

j2.PostString(Main.cLocalIp & "/neworder", CreateMap("order": ord, "items": s))

However, s looks like a list instead of a map.

possibly related. (in addition to issues raised by aeric)

From browser if you call a post method, you are bound to get that error.

The poststring accepts both the 2 params as string only. Can't pass map in 2nd parameter

Sorry. I forgot convert it to string.

B4X:

j2.PostString(Main.cLocalIp & "/neworder", CreateMap("order": ord, "items": s).As(JSON).ToString)

j2.GetRequest.SetHeader("order", ord) ' ord is a map j2.GetRequest.SetHeader("items", s) ' s is a map

they ca not work.
A header is usually a single STRING. Cou can not put Maps in there.

what is the solution to make it work? it works from postman, python and in php. Why can't in our b4j?
