Android Question java.net.ProtocolException: Unexpected status line:

Alberto Michelis · Jul 18, 2019

B4A 8.8
Using OkHttpUtils2
Fetching a web page that is fetched ok with b4a older versions, Im getting the following error.

!!! java.net.ProtocolException: Unexpected status line: <!DOCTYPE html>

I can access the page using Firefox browser

http://132.148.84.1:8633/xmloc?F=Lanz&E=O-25-5-20

The result is a simple xml

What is a status line? what should I add to the page to get rid of this error?

The http response is invalid. It should start with the status line (ex: Http/1.1 200 OK).

You can use Socket with AsyncStreams to read it.

I cant use Sockets
You mean first line of the response must be:
<Http/1.1 200 OK> ?
or how to add Http/1.1 200 OK to the response?

Why not?

Is this your server?

Alberto Michelis · Jul 18, 2019

Yes it is but is a server made in Clarion and does not supports sockets.
Ive added Http/1.1 200 OK in the first line of the page and now Im getting another error:

ResponseError. Reason: java.io.IOException: unexpected end of stream on okhttp3.Address@4068ce87, Response:

There must be an empty line after the headers and before the body.
Make sure to use CR & LF as the end of line characters.

I had this problem, I solved putting
at the time of the request
job.GetRequest.SetHeader ("Connection", "close")

Ex:

B4X:

Dim job As HttpJob
job.Initialize("", Me)
job.Download("http://myhost.com/api")
job.GetRequest.SetHeader ("Connection", "close")
