OpenWeathermap http error when making REST call
Hello ,
I am trying to make a REST call using the example given in documentation for Creating REST Services and Clients with Ensemble.
Class Test.REST.WeatherOperation Extends EnsLib.REST.Operation
But i receive below mentioned error. If anyone can help me out here.
ERROR <Ens>ErrGeneral: ERROR <Ens>ErrHTTPStatus: Received non-OK status 404 from remote HTTP server: 'HTTP/1.1 404 Not Found':<html>
<head><title>404 Not Found</title></head>
<body bgcolor="white">
<center><h1>404 Not Found</h1></center>
<hr><center>nginx</center>
</body>
</html>
Thanks,
Jimmy Christian.
it's not related to ENS . the error is pure HTTP
<
Ens>ErrHTTPStatus: Received non-OK status 404 from remote HTTP server: 'HTTP/1.1 404 Not Found':<html>
simply tells you that your URL is wrong.
try it in browser to verify it exists
Yes, Thank you. I just corrected the URL and it works now. Thank you Robert. One more question if you can assist in this context.
So the response message i got back is in the HttpResponse object.
How can i convert the HttpResponse.Data property to JSON and parse the values. Since the data i received is Stream, is there a way i can convert the stream to Dynamic Objects and parse it?
Thank you.
Jimmy Christian.
the data property is a standard HTML page.
I'm not aware of some function in Caché that converts HTML to JSON.
But asking Google "convert HTML to JSON" shows that this a standard feature in JavaScript.
so I see 2 options:
- write your own parser (or someone in the community has done this before ???)
- call an external tool (eg. node.js) to it for you
see: https://stackoverflow.com/questions/34504050/how-to-convert-selected-html-to-json
or https://stackoverflow.com/questions/12980648/map-html-to-json
or https://stackoverflow.com/questions/43469412/convert-html-source-code-to-json-object
What version are you on? If 2016.2+ then you can convert JSON stream to dynamic object via:
Hello Eduard,
i was able to convert the HttpResponse.Data to String and than to the Dynamic Object. Worked great. Thank you.
On the same line, i need to ask you of any template or suggestion to send a JSON data to a REST API.
For eg. below is the JSON
{"name":"abcdefghi","salary":"123","age":"23"}
How do i send it to http://testing.restapiexample.com/api/v1/createemployee with POST request using the set tSC=..Adapter.PostURL(tConfig.URL,.tHTTPResponse,,pRequest)
Below code is not working.
Your help will be appreciated.
Thanks,
Jimmy Christian.
You don't need to convert to string, pass stream to FromJSON method and it would work.
