Android Question problems with HttpJob , PostString , SetContentType , send json

invaderwt · Jan 6, 2015

I need send a block of json in a post situation.
How could I do that, I did a lot of tries like below
First Try

B4X:

Sub Button1_Click
Dim  job2 As HttpJob
  'Send a POST request
  job2.Initialize("Job2", Me)
  job2.PostString("http://www.mysite/users/sign_in/", "[email protected]&password=pass")
End Sub
Sub JobDone(job As HttpJob)
  ProgressDialogHide
  If job.Success Then
  ToastMessageShow ("SuccessFully Finish !", True)
  json.Initialize(job.GetString)
  'ShowData
  Log(job.GetString)
  job.Release
  Else
  Msgbox(job.ErrorMessage, "Error")
  End If
End Sub

second try

B4X:

Sub Button1_Click
Dim job1, job2, job3 As HttpJob
  'j.Download2("http://www.mysite/users/sign_in", Array As String("email", ""))

  'Send a POST request
  job2.Initialize("Job2", Me)
  'job2.PostString.SetContentType("application/json")
  Dim text As String
  text = "{'email':'user@','password':'p@ss'}"
  'job2.PostString("http://www.mysite/users/sign_in", text)
  job2.Download2("http://www.mysite/users/sign_in", Array As String ( "email","user@","password","p@ss"))
' job2.GetRequest.SetContentType("application/json")

  'Send a GET request
  ' job3.Initialize("Job3", Me)
  ' job3.Download("http://www.mysite/users/sign_in?email=shopping@mysite&password=p@ss")
End Sub

B4X:

Sub JobDone(job As HttpJob)
     ProgressDialogHide
 
     If job.Success Then
 
 
       ToastMessageShow ("SuccessFully Finish !", True)
       json.Initialize(job.GetString)
       'ShowData
       Log(job.GetString)
       job.Release
     Else
         Msgbox(job.ErrorMessage, "Error")
       End If
End Sub

I need do something like that but i really can´t send the post with a json some one know how do that?
He send a json and recive back a json.
Thank

B4X:

- curl -H 'Content-Type: application/json' -H 'Accept: applicatíon/json' -X POST http://www.mysite/users/sign_in -d '{"user": {"email": "user@", "password": "p@ss"}}'
{"id": 2 ,"email":"asd","segment":null,"authentication_token":"eLBJjasd9as7_9871923"}^

you forget to set the request-headers

B4X:

Content-Type: application/json
and
Accept: applicatíon/json

See https://www.b4x.com/android/forum/threads/set-http-request-header-with-httputils2.39413/#content

Hi, now I can send the data but the data back to me, I can´t recive the json come only a html when I tried in the https://www.hurl.it/ come a json response
And the back end send me the correct line to send the pass and the user so now

B4X:

 text =  "usr[email]=mail&usr[pass]=pass"

response form website:

B4X:

{"email":"","password":null}

response for app:

B4X:

** Activity (main) Pause, UserClosed = true **
** Activity (main) Resume **
** Activity (main) Pause, UserClosed = false **
** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
** Service (httputils2service) Create **
** Service (httputils2service) Start **

it´s better use HttpUtils2 instead of HttpClient or I need use httpClient in this case?

DonManfred · Jan 7, 2015

Without seeing what you are doing it is hard to give congrete answers...
As i can see in the log you posted...

B4X:

  <!-- This file lives in public/404.html -->
  <div class="dialog">
  <div>
  <h1>The page you were looking for doesn't exist.</h1>
  <p>You may have mistyped the address or the page may have moved.</p>
  </div>
  <p>If you are the application owner check the logs for more information.</p>

looks like the page you requested did not exists...

Hi , I think in the same way that you , but when this page come like a answer i had create a session on the website.
This is a error yet from the site
if I use this site :

Create a session but i can´t redo this in the app

invaderwt · Jan 10, 2015

some one know how i create the session on b4c and maintain the session

Erel · Jan 11, 2015

Cookies are maintained automatically. If the session is based on cookies then it should work automatically.

You can always switch to HttpClient and then manually get the cookies from the response headers.
