Android Question WebService Rest

[Cristian Regazzo]

Good afternoon,

I need to consume a WebService Rest in my App.

I looked in the forum and did not find an example.

Someone as an example of consuming WebService Rest?

Thank you.

See OKHttputils. You need to know the format the web service expects and the data it needs. If you post it, we can take a deeper look (e.g. does it need authorisation?)

Good Morning,

In my tests, I'm not using authentication to consume the WebService.

My problem is in getting the result of my WebService Rest.

For SopUI or PostMan, I get the feedback perfectly, however on Basic4Android I'm not getting it.

Checking the OkHttpClient Documentation, I should use GetAsynchronously, but one of the Event parameters is Output, however I do not want to save the result to a file.

How do I get the consumption result of the WebService Rest in the ResponseSuccess Event, since the GetString event has been deprecated.

Thank you very much.

I'm not getting it.

No response at all? What does Job.GetString say?

I do not respond to "false" calls, too in my php environment (so an attacker get's nothing back and does not know what's happening). Hard to say when we don't know how to call it. Is there a documentation how the call has to be done? (parms).

Maybe you should post the URL of the rest-api you are using. (Website, documentation-site)

As @KMatle already said okHTTPutils is the way to go.

Hiding the code which you are using without success will not help us to help you fix it.

Good afternoon,

Sorry for the delay.

I had to redo some settings in my Firewall to release such access.

I'm trying to make Rest service the following URL:

http://resttst.yaskawa.com.br:9090/rest/sample

Through PostMan, it works normally, but I can not get the return via Basic4Android.

Thank you very much.

Good afternoon DonManfred,

Thanks a lot for the help. Worked perfectly

Just got a question, can I consume the WebService Rest using the InitializeGet command?

Thank you again,

 

[DonManfred]

My example IS using GET

 

[Cristian Regazzo]

Good afternoon DonManfred,

Thank you again.

It's just that I was a bit confused (I'm new to Basic4Android) because you used Register.Download, and I was trying to consume the RestServ WebService through the REST.InitializeGet ( "http://resttst.yaskawa.com.br:9090 / Rest / sample ") and using the HttpClient1.Execute (REST, 1) command.

Thank you.

Last time for me:
Remove httpclient and use okhttputils for this. This is the way to go!

 

[Cristian Regazzo]

Many thanks again for the help.
