Errors when a HC2 scene starts a scene in another HC2

[muc 1]

Hello,

I want to start a HC2 scene from another HC2, but something is going wrong, I've no idea what.
Perhaps a missing parameter?
Who can help?

 

1. Try:

  dat= json.encode({args={16,18,19,22}})
  datLen= tostring(#dat)
  print(dat, datLen)
 

  http= net.HTTPClient()
  http:request("http://192.168.2.38:80/api/scenes/218/action/start",
  { options= { headers= { ['Authorization'] = "Basic abc...xyz=",
                          ['Content-Type'] = "application/json",
                          ['Connection']= "close",
                        },
               data= dat,
               method= 'POST',
               timeout= 5000
             },
    success= function(resp)
      print("resp.status:", resp.status, "C-Len:", resp.headers["Content-Length"])
    end,
    error= function(err) print("Err:", err) end
  })

 

Result:

[DEBUG] 22:49:43: {"args":[16,18,19,22]} 22
[DEBUG] 22:49:43: 2022-02-06 22:49:43.325015 [ debug] error reading from socket: End of file
[DEBUG] 22:49:43:
[DEBUG] 22:49:43: Err: End of file

 

Great surprise: data are sent !

 

- - -

with   ['Connection']= "Keep-Alive"    instead of   ..."close":

 

[DEBUG] 00:51:02: {"args":[16,18,19,22]} 22
[DEBUG] 00:51:05: 2022-02-07 00:51:05.112165 [ debug] Detected chunk with zero size, terminating connection
[DEBUG] 00:51:05:
[DEBUG] 00:51:05: resp.status: 200 C-Len: nil

 

  print(json.encode(resp))  shows:

[DEBUG] 00:51:05: {"data":"","status":200,"headers":{"Cache-Control":"no-cache, no-

store","Transfer-Encoding":"chunked","Server":"nginx\/1.8.0","Content-Type":"application\/json;charset=UTF-8",

"Date":"Sun, 06 Feb 2022 23:51:05 GMT","Connection":"keep-alive"}

 

data are sent here too!

 

-----------------------------

 

2. Try with added line:    ['Content-Length'] = datLen,

 

Result:
[DEBUG] 22:54:09: {"args":[16,18,19,22]} 22
[DEBUG] 22:54:09: resp.status: 400 C-Len: 172

 

no data sent

with  ['Connection']= "Keep-Alive"  instead of ..."close"  also no data sent

 

-----------------------------

 

Thanks in advance!

Please check if your Authorization is correct and the user has permissions to run that scene.

in addition I am using these headers and it works just fine

headers={ ["Content-Type"]="application/json;charset=UTF-8",

                                    ["Accept"]="application/json",

                                    ["Authorization"]="Basic vvbnjjknm....."}},

Hello cag014,

thank you for your answer.

 

Authorization is correct, user has permission to run that scene,

so I added     ;charset=...

and    ["Accept"]=...

but nothing changed. (data is received!)

 

Your sending scene doesn't write something like this ?

[DEBUG] 14:32:07: 2022-02-08 14:32:07.725228 [ debug] error reading from socket: End of file
[DEBUG] 14:32:07:
[DEBUG] 14:32:07: Err: End of file

 

or when   ['Connection'] = "Keep-Alive"   is added  like this ?

[DEBUG] 14:36:26: 2022-02-08 14:36:26.459030 [ debug] Detected chunk with zero size, terminating connection
[DEBUG] 14:36:26:

 

Is in your receiving scene a command to 'answer' something for the sending scene to have some 'data' to read ?

 

Thanks!

Hello cag014,

 

one more question:

there is no need of   ['Content-Length']=  ?
