RESTfull webservice data retrieved

[anoredis]

Hello, this is my first attempt to create an application that utilizes Web Services. Does anybody know how to access the data retrieved from a web Request Block? I have the Web Request block in which I have assigned the URI, the method to POST, the authentication method to basic with my credentials filled in, the encoding type to urlencoding and the output variable to dataRetrieved.
When I try to log AppState.dataRetrieved it logs [object Object]
How can I check what comes back?

Hi,

Could you post here snippet of URS HTTP log to see what is coming back from your web service?

R.

Hello Rene, thank you for your immediate response. I don't think it has something to do with the URS. I just do not know how to access the data returned. My web request is done correctly because i can see in the MPC logs that I get back [code] var WebRequest1Response = {"result":"jY8UteuGBjTbANyJFE5Y+99cFcbNNMkYwCWRAnmHul+hLtkR26xGJo+J30jimY6nfakIEM66ixk="};] [/code]

How do I access that? I am trying to access it like AppState.dataRetrieved.result but it gives me a scemantic error. In the mcp logs I see that [code] exec_error TypeError: AppState.dataRetrieved has no properties [/code]

Hi,

Sorry, I thought you're talking about calling web service from URS... Do I understand you correctly that dataRetrieved variable is configured as output parameter of the Web Request block?

R.

[anoredis]

Exactly Rene! You can find my complete configuration for my Web Request Block in my first post.
My problem is that I get the correct response from the service but I do not know how to access the data retrieved

[René]

Do you see in MPC log that web request output has been assigned to the dataRetrieved variable?

R.

[anoredis]

Yes, MCP logs states that
[code]AssignRuntime.cxx:48 Execute(): Script [AppState.dataRetrieved;AppState.dataRetrieved=WebRequest1Response;][/code]

[anoredis]

Ok, got it!

From MCP logs I saw that
[code]Runtime.cxx:424 EvaluateExpression(): Expression [var webReqResponse = {"result":"jY85k="};]}[/code]

which is a json object. So I got the value by
[code]AppState.dataRetrieved.result[/code]

[anoredis]

Can anyone please tell me how can I check for the response? I want to access the response headers and check if it is a 200 OK to proceed or anything else to provide different scenarios.

Enable the logs on your app so it will save them on MCP tmp folder.
I think the name is com.genesyslab.savetempfiles or like that. It is on the GVP help file under Logs section.
You can set it as ALL, PAGES, etc. Set it as PAGES so it will save requests and responses from MCP to the HTTP servers. Also helpful to see WS responses for example.

Thank you cavagnaro for the quick response! 
I am really new to CTI and composer so I am not sure I understand you. I see in my MCP logs that

so I was hoping to get something from it because I see a lot of 200 OKs there.
I was hoping that I would get the response on the object of the Request and check it in my program with something like [code]WebRequest2.StatusCode == '200' [/code] or with the use of .getAllResponseHeaders()
Some lines below I see (I guess) the savetmpfiles that you mentioned(?)

Hi,

I did quick test and returned JSON object contains key 'errorMsg' where you can find text description of thrown HTTP error e.g. Internal Server Error, Not found etc. It is possible to return more details about HTTP errors but that would require modification of getWebRequestData.jsp file (or getWebRequestData.aspx for .NET) provided by Composer.

R.

[anoredis]

Thank you Rene! I was able to to a check in a Branching Block if(WebResult.errorMsg.indexOf('404')) which serves me well but I am not able to do the same for a 204 because it is not an Error...

[cavagnaro]

No content...mean the WS? If so I'd see the JSon object properties and maybe length.

[anoredis]

I tried messing with the WebRequest.aspx but no lack. I have managed to return the key-value pair in my JSON object but with a fixed value like [code]"headers" : "returnedHeaders"[/code]
I have tried webresponse.Headers but no luck. How should I get the values that I want into my variable? I  am really new to C#.
I could post my WebRequest.aspx but it's really long. However, I think that it's a pretty standard page for all projects.
