MvCapture equivalent for Templates/storemorph

[ids]

Last I had checked mvt:capture wasn't yet available for template scripting. Is this still the case?

If not, what or is there an equivalent?

More info: I am needing to run some static JSON through mvt:call. An MvCapture capability would make this easy. So what's my alternative?

Thanks.

I have a blog article with some code for converting Miva objects to JSON: http://themagicm.com/store/miva-json...revisited.html. I don't know if it's possible to convert the Miva Script to template code; but you could paste it into a small utility module and call it with mvt:do tags on your template. Also, I think Ray Yates has built this functionality into his Toolbelt module.

<mvt:call METHOD          = "RAW"
          ACTION          = "https://someurl"
          CONTENT-TYPE    = "application/json"
          HEADERS         = " 'Authorization: Basic xxxxxxx' $ asciichar( 13 ) $ asciichar( 10 ) "
          FIELDS          = "l.json">
   <MvEVAL EXPR = "{ s.callvalue }">
</mvt:call>

Can't recall where I derived this example, but attempting to use it. The var l.json is valid json. There is no complaint from compiling the template. Running the page says fields line is "Array index must be positive integer." OK, but when the contents of this var is a simple string instead I don't see a complaint. My conclusion: The JSON content needs to handled somehow. I'm assigning the json with mvt:assign. So, what do I do?

I haven't used mvt:call, but I think maybe you need to put quotes around l.json in the FIELDS attribute. -- single quotes, that is, inside the double quotes. This may be needed for some of the other attributes too. I know Store Morph parses tag attributes differently from Miva Script, but I'm not sure of the exact rules; they may vary from one attribute to another. (Is there a document somewhere that explains that?)

Have you tried rendering the s.callvalue entity as mvtj:

(May have to first use mvt:assign with a system variable)

I was trying to prototype with smt, but this isn't working. I switch to a component module. I am able to get back responses that confirm I talking to the server but the errors I get back are that the server isn't recognizing the formatting of the JSON. I am guessing that part of the issue is I may not know enough about JSON, but the DOCS for this server are presumably supplying valid JSON examples.

Main error on the request that should be working is this:

HTTP/1.1 415 Unsupported Media Type

This seems to suggest that the JSON isn't correct, formatted incorrectly, or the string isn't being recognized. Another tidbit I found was that the Content-Type is being read after the fact. But I'm not sure that applies here.

I switched to a component module style solution based on Burch's code from that post. This issue I was having was that the JSON string in the MvCapture was being crunched to NULL for some reason. Maybe I missed something in the syntax but it always compile. When executed l.json was NULL. My solution was to construct the JSON using mvassign.

Wasn't ideal to have to do this but it worked. So much for quickly prototyping something aye....
