json

If the content type of the POST is application/json then the Web Script Framework will detect this and parse the JSON into the helper object called json. This allows the developer to access the JSON data using properties with the get method, for example json.get("field").

If a POST was submitted to /somewebscripturl, with the following JSON data:

        
{
  somevalue: "hello",
  morestuff: 123
}

Then in the web script JavaScript code it would be possible to access the value of the somevalue field using the JavaScript code:

  json.get("somevalue");

If the data posted is a JSON object, the json root object will be of type JSONObject. If the data posted is a JSON array the the json root object will be of type JSONArray.

Consider the following example script:

        
function abtest(){

    // Native JavaScript object                                                                                                                                            
    var myObj = {'name':'Test Object','size':100};

    // Convert native JS object to string                                                                                                                                  
    var myObjAsString = jsonUtils.toJSONString(myObj);
    model.myObjAsString = myObjAsString;

    // Convert string back to native object                                                                                                                                
    var tonyObject = jsonUtils.toObject(myObjAsString);

    // Get JSON data and load into model
    model.firstName = json.get("firstName");
    model.lastName = json.get("lastName");

}

function main(){
    abtest();
}

main();        
        
        
      

The script could be invoked using cURL as follows:

    
curl -uadmin:admin -H "Content-type: application/json" -X POST -d '{"firstName": "Fred", "lastName": "Bloggs"}' http://localhost:8080/alfresco/service/abtest    
    
  

The JSON data could then be processed by the controller script or simply added to the model before displaying by using the view:

        
<p>Hello ${firstName} ${lastName}</p>
