Android Question httpserver

[catyinwong]

I am testing with the httpserver library with local host, and try to post http jobs to the server but the connection failed with the error:

 ResponseError. Reason: javax.net.ssl.SSLHandsshakeException: Handshake failed, Response:

I did some search on the issue and found many suggestions about "initializeacceptall" but I am confused where I can add that?

[B4X] OkHttpUtils2 / iHttpUtils2 and accept all option

Note that OkHttpUtils2, jOkHttpUtils2 and iHttpUtils2 are actually the exact same b4x library. jOkHttpUtils2_NONUI was required as a special version for non-ui B4J apps. It is no longer required and shouldn't be used. Starting from v2.90 it is very simple to initialize the internal http client...

Yes, that's what I am confused.

I m now using OkhttpUtils2 but I cant see anywhere for initializeacceptall

 

[catyinwong]

Found the source codes and added. Thank you.

 

[catyinwong]

Bad news. The same error appears even if I added the Initializeacceptall.. any other suggestions? ?

 

[DonManfred]

You are doing something wrong when you use the sourcecode!

Go again over the tutorial, add the HU2_ACCEPTALL conditional symbol in the Buildconfigurations.
REMOVE the sourcemodules. Only use the Library.
Also make sure to use the newest version of B4A (10.0 as of now).

The tutorial says the jars are in B4J internal libraries but they are not. The best I can Google is httpclient V4.2.5 and http core V4.0, still far from the needed versions....

 

[DonManfred]

The tutorial says the jars are in B4J internal libraries but they are not.

The okhttputils2.b4xlib, okhttputils2.jar and okhttputils2.xml ARE/IS inside the internal library folder.

No need(!) to google for any httpclient. It is not relevant.

Which tutorial you are following?
Do you have SSL in your localhost?

so the followings are not needed?

#AdditionalJar: httpclient-4.5.2 
#AdditionalJar: httpcore-4.4.4 
#AdditionalJar: commons-codec-1.9

What is SSL?

Not when you want to use okhttputils2.

WHICH Thread? Which library?

 

[catyinwong]

I have done the upgrading, with okhttputils2 v2.92. config with HU2_ACCEPTALL, but the same problem still exists.

And for the SSL, how do I know if my device have it or how do I build it?

it is the example link under the tutorial thread. never mind if the additional jars are not needed.

Do you access your intranet web services using http or https?

I am testing with the httpserver library with local host, and try to post http jobs to the server

I am confused. You said you are testing in local host. How do you test it? Do you create a B4J app to connect to your localhost (IP=127.0.0.1) or connect to another server with different IP?

I add a menu item at the main activity, and which start a http job to put string to the localhost.

so the codes are within the same app

I have been facing the same problem for a while with my Oreo (Android v8) tablet.. but after updating my codes by following the thread below I'm now able to connect to my https server.

SSL Websocket client

Trying to connecting to my websocket server: closed javax.net.ssl.SSLProtocolException: SSL handshake aborted: ssl=0x63a133b0: Failure in SSL library, usually a protocol error error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure (external/openssl/ssl/s23_clnt.c:741...

It seems that my Oreo tablet did install the security provider and everything is ok now.. thanks to the guru Erel.. ???

Note: In my case adding the HU2_ACCEPTALL did not solve the problem as it was something to do with the protocol library.
