JSON Data Structure

Startbeitrag von ech madriaga am 24.11.2015 06:22

Hi All,

I need your advice.
How I can change/modify the original or current output number 1 to the structure in Number 2. I need to put and "Enter Command" after "[" and before "]".

1. Original Output - [{"id":1,"type":"Model","modelName":"Model Name","assettype":{"id":1,"type":"AssetType"},"manufacturer":{"id":1,"type":"Manufacturer"},"warrantyType":{"id":1,"type":"WarrantyType"}}]

2. Final Output - [
"modelName":"Model Name",

Here's my code:
myRequest is restRequest
myResponse is restResponse
vResvar is Variant
myRequest.URL = "http://localhost:8081/helpdesk/WebObjects/Helpdesk.woa/ra/Models?&username=admin&password=admin";

//myRequest.Method = httpPost
// just part of json sample, make it yourself right as a complete json

myResponse = RESTSend(myRequest)

IF ErrorOccurred THEN


POUR TOUT Models DE vResvar.results

TableAjouteLigne(TABLE_NoName1,Models .id,Models .modelName)


But its giving me an error:
Le variant n'est pas un objet
Code erreur : 2250

I think the problem is the current structure of the JSON. I need to change it to Number 2.
But how?



Your JSON represents an object but objectes a not supportted by JSONToVariant/VariantTOJSON. Try to convert object to associative array - remove framing [].

for WD20:

This will work fine with the variant. Use the power of the debugger to see how the variant is constructed to use it later on in your for each loop.

You see that the JSON structure is converted to the Variant

If you use this code (Code from the 'convert' button)

sJsonData is string = EDT_NoName1

vMyData is Variant = JSONToVariant(sJsonData)

FOR EACH line OF vMyData

you will get this output:

You will have to use the correct statements to get the dynamic data from the variant.

So it is very easy to work with JSON data.

Another way is to define a structure that represents your Json data and use deserialize to fill the structure from you JSON data, but this is more complex but it depends on the what you need the data for.

Hope this helps !

Thank you Danny Lauwers.

Now, I had done for displaying the information from json.
Can you help me on how I can add, modify, and delete a information using json?
Do you have any samples?
