iOS Question Cocoa Error 3840

[Rokiu86]

Hi.

I have an issue. Here the code: (very simple)

Sub JobDone (job As HttpJob)

  If job.Success = True Then

  Dim parser As JSONParser
  parser.Initialize(job.GetString)
  Dim rows As List
line 94: rows= parser.NextArray
...

Error:
Application_Start
Application_Active
Error occurred on line: 94 (main)
Error parsing string: Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (Garbage at end.) UserInfo=0x17e5dac0 {NSDebugDescription=Garbage at end.}

I read about this issue but not for B4i.

With my web browser, I can see this Json string with post method:
[{"nombre":"MODA"},{"nombre":"PERFUMES"}]

I tested with json tree Example and is ok.

Thanks for help!!

Add a Log(job.GetString) to check the returned string. Based on the error message there is some invalid char(s) at the end of the string.

Hi.

Here is the log, adding Log(job.GetString). Return a json string and a HTML code. It's fine???

Application_Start
Application_Active

[{"nombre":"MODA"},{"nombre":"PERFUMES"}]

No. You should first remove the non-json string:

Dim s As String  = Job.GetString
s = s.SubString(0, s.IndexOf("]") + 1)
'now you can parse s as a json string

It's working! Thanks!
