Android Question okHttp

sule · Nov 29, 2016

ok how do you implement this code with okHttp
Code:

B4X:

Sub Process_Globals
Dim hc AsHttpClient
End Sub
Sub Globals

End Sub
Sub Activity_Create(FirstTime As Boolean)
If FirstTime Then
hc.Initialize("hc")
hc.SetHttpParameter("http.protocol.handle-redirects",False)
EndIf

okhttp dosnt have .SetHttpParameter property

there is no answer there

Use the source download from the okhttp thread.

Do the changes (which you need) in this source and use it then... Or maybe compile to library and use the self-compiled one

Sule you are very FAST. Then next time look and read better pls.
Well... in POST you have this file that you can download:

Here you have source ( Class Module ). This code you can add all function you need.

Try this:

B4X:

Dim jo As JavaObject = hc
jo.GetFieldJO("client").RunMethod("setFollowRedirects", Array (False))

jo.GetFieldJO("client").RunMethod("setFollowRedirects", Array (False))

getting error
java.lang.RuntimeException: Object should first be initialized (JavaObject).

Have you called it after hc was initialized?

sule · Nov 29, 2016

it still auto redirect

sule · Nov 29, 2016

Erel can you plase try to write simple code when auto redirecting is disabled or i just have to give up on this
when i request a url i got response from server Found 302 (temporarily moved) and i got auto redirected to another url . I just want to get Location header and stop right there ty

This code works properly:

B4X:

Sub Process_Globals
   Private hc As OkHttpClient
End Sub

Sub Globals

End Sub

Sub Activity_Create(FirstTime As Boolean)
   If FirstTime Then
     hc.Initialize("hc")
     Dim jo As JavaObject = hc
     jo.GetFieldJO("client").RunMethod("setFollowRedirects", Array (False))
   End If
   Dim req As OkHttpRequest
   req.InitializeGet("http://www.b4x.com")
   hc.Execute(req, 0)
End Sub

Sub hc_ResponseError (Response As OkHttpResponse, Reason As String, StatusCode As Int, TaskId As Int)
   Log(Response.ErrorResponse)

End Sub

Sub hc_ResponseSuccess (Response As OkHttpResponse, TaskId As Int)
   
End Sub

Note that it is not possible to get the headers when there is an error. It will be fixed in the next update of OkHttp.

Sub hc_ResponseSuccess (Response As OkHttpResponse, TaskId As Int)

Not with the actual version.
But if i remember correctly i read today that this will be fixed for the next update

next update maybe 2 years from now

if i read correctly i think erel will release a new version of the okhttp-library in the future.
I don´t think it will last two years...

Yes. I'm sure that you have already seen the code. It is the same code that uses "http.protocol.handle-redirects".

if i try to use httpclient i got thei error
Compiling generated Java code. Error
B4A line: 24
hc.Initialize(\
javac 1.8.0_112
src\b4a\example\main.java:381: error: cannot access ClientProtocolException
_hc.Initialize("hc");
^
class file for org.apache.http.client.ClientProtocolException not found

DonManfred · Nov 30, 2016

AGAIN: Replace the old http lib with the new okHTTP (and okhttputils2). Based on the error you are still using the old one

sule · Nov 30, 2016

the whole point is to use old httpclient becose i cant get headers with new okhttpclient

Erel · Nov 30, 2016

You should use an older version of android.jar if you want to use Http library. For further discussion please start a new thread.
