Barco Clickshare api ssl/https 🤔

pyromaniak

Hello guys

I am blocked on a Barco clickshare cse800 !

I only need to change one setting from one to two screen.

There is an api but only ssl (https).

Manual here https://www.barco.com/services/website/en/TdeFiles/Download?FileNumber=R5900056&TdeType=1&Revision=01&ShowDownloadPage=False

Does someone know how to connect to it via https? I looked everywhere and didn't find a hint!!

Thanks a lot in advance!

Best regards

TLS_CLIENT_OPEN
Opens a port for TLS communication with a remote device.

Syntax:

integer TLS_CLIENT_OPEN(LocalPort, hostname, port, mode)

Parameters:

LocalPort- A user-defined (non-zero) integer value representing the local port on the client machine to use for this conversation. This local port number must be passed to TLS_CLIENT_CLOSE to close the conversation.

hostname - The host name or IP address of the remote host.

port - The connecting port on the remote host, usually port 443 for standard HTTPS connections.

mode - 0: TLS_VALIDATE_CERTIFICATE (perform certificate validation), 1: TLS_IGNORE_CERTIFICATE_ERRORS (connect to the remote site while ignoring certificate errors or mismatches)

Returns:

This function returns 0 is all parameters are accepted, or a positive value indicating the offending parameter if there is an error.

Example:

TLS_CLIENT_OPEN(5000, '192.168.0.1', 443, 0)

Note - when using mode = TLS_VALIDATE_CERTIFICATE the server certificate must be imported into the NetLinx masters CA.

As Ian said use TLS, I use mode of 1 and it works with no problem the port number is 4001 now, and you will need to do basic authentication.

Thanks guys!!! Can't wait to test it out! Thanks a lot

Sorry for bothering you again but I fail miserably to make it work!

I can now connect to it with the TLS mode 1.

But I struggle with the basic authentification and header.

I never have an answer from the device.

I tried a GET command with:
SendCommand ("'GET /v1.0/OnScreenText/Location HTTPS/1.1',13,10")
SendCommand ("'Authorization: Basic ',fnBase64('integrator:integrator'),13,10,13,10")

The SendCommand function is just for connecting first and stacking commands:

DEFINE_FUNCTION SendCommand(CHAR sCmd[]){
IF(nIpConneted)
SEND_STRING dvIP, sCmd
ELSE {
PushStack(sCmd);
ConnectIP();
}
}

Can someone help me ? Thanks a lot in advance!

See if it works with changing the HTTPS/1.1 to HTTP/1.1 as the HTTP commands are independent from TLS

Hella again

Get works perfectly but I can't set a Parameter. I tried many hours.

I tried many ways, even the example in the API manual from barco...

Did someone already made it works ?

Thanks a loooooot !!

When i send this request : // this is the output from what I send.
POST /v1.0/OnScreenText/Location HTTP/1.1
Authorization: Basic aW50ZWdyYXRvcjppbnRlZ3JhdG9y
Content-Length: 19
Content-Type: application/json; charset=utf-8

{ "value": "test" }

I Get the answer :
HTTP/1.1 404 Not Found
X-Powered-By: Express
Content-Type: application/json; charset=utf-8
Content-Length: 59
Date: Tue, 08 Jan 2019 16:49:09 GMT
Connection: keep-alive

{
"status": 404,
"message": "Resource does not exist"
}

first thing is I dont see the host portion of the header (Host: IP_ADDRESS:4001). Add that in and see where that gets you

pyromaniak

Thanks for the answer.

I tried but nothing changes.
And it works with the GET. should be the same as the PUT no ?
Thanks a lot !

POST /v1.0/OnScreenText/Location HTTP/1.1

Content-Length: 17
