Use HTTP Proxy - Is there a way to automatically turn on/off to use proxy?

Edith1 — Wed, 21 Apr 2021 17:37:12 GMT

Hello all, I am using component tRestClient and turn off proxy (in Advanced Settings - uncheck use HTTP proxy) to run the job on my local computer, however, when I need to remote execute job on TAC server I need to turn on proxy. Is there a way to code or program this setting automatically using context variables?

Hi, yes you can via the dynamic settings view in the component.

Thanks for the feedback @guenneguez jeremy.

I cannot get the dynamic setting to work though. I attached a screenshot of a simple job with the trestclient set up. The context.UseProxy is a boolean variable. What am I missing? When the UseProxy is true, will it use the host, port and username info listed on the advance settings? In advanced setting, the "use HTTP Proxy" is highlighted yellow. I did add the host and port.

Hello you did it right, when the variable is true it use all informations you enter , if it's not it dont use proxy.

The "use HTTP Proxy" is highlighted yellow because now it's dynamic and is your variable wich control it.

Thanks @guenneguez jeremy for the response 😀. The dynamic settings for trestclient on studio version 7.3 does not work. Oh well, I'm hoping Taland can fix this in the future.

maybe I have a solution by code injection in the component :

so first create a context variable proxy with the boolean value.

then

in TRestClient advanced settings :

Connection timeout (seconds) value : 30 * 1000L));/*

Receive timeout (seconds) value : 60 * 1000L));boolean use_proxy_tRESTClient_1 = context.proxy;//

proxy password value : ""*/if (use_proxy_tRESTClient_1) {final String decryptedPassword_tRESTClient_1 = "your password here"

if you look the code generated in the code view, those injections will comment a part of the trestclient code and write a new one with your boolean as triggering value for use proxy.

That's exactly what I did before. It seems like the context Boolean variable for the dynamic setting is not being recognized. When I manually change the dynamic setting from false to true, it works fine. However, when its pointing to the context variable, it doesn't work.

Here's the code for the job:

if (!inOSGi) {

conduit_tRESTClient_1.getClient().setReceiveTimeout((long) (60 * 1000L));

conduit_tRESTClient_1.getClient().setConnectionTimeout((long) (30 * 1000L));

boolean use_proxy_tRESTClient_1 = context.UseProxy;

}

Here's the error I get when the context variable is TRUE ( I'm printing to console the context variable to ensure it's turning on or off).

Starting job TestAPI_ProxyOnOff at 09:24 07/05/2021.

**So technically the Dynamic setting works if you manually change the value; however it doesn't work if you automate the value to use the context Boolean variable. **
