Is it possible to return multiple JSON objects in the request header with Struts1? I am presently returning a single JSON objects, however the need now is to return a second data structure. All the client-side processing works perfectly for the single data structure in the single JSON objects, I really do not want to complicate it by putting two hetrogenous data structures in a single return JSON object. tia.
I don't know struts or why you can't return multiple JSON objects, but if you genuinely can't, why don't you return a list of your objects? you can unbox them at the receiving end.
in other words, if you were previously returning obj = {...}, and now need to return that as well as obj2 = {...}, you can return [obj, obj2].
maybe this doesn't solve your problem, but it'll get you around it pretty easily.

I've used this Flow to return the count of any Sharepoint list to Powerapps.
https://masteroffice365.com/get-sharepoint-library-or-list-total-items-from-power-apps/
How would I modify it to return the contents of a list to Powerapps, so that I can use Powerapps to put it into a collection?
Would this mean I don't have to worry about Delegation if the list has more than 2000 items?
This is what I've tried so far.
There is a variable TotalItemsCount which I have changed to ListItems. Instead of using an Integer I set ListItems to an array.
In the Get Library list contents I use this for the URI.
concat( '_api/web/lists/GetbyTitle(''', first( body('Filter_Library_List_Being_Queried') )?['displayName'], ''')/Items' )
I'm not sure what to put in as the last step given that I want it to be able to return the contents of any list. I think this rules out a parse json step as that requires a definite schema.
I've added an ApplyToEach
I'm getting this error message when it runs.
ExpressionEvaluationFailed. The execution of template action
'Apply_to_each' failed: the result of the evaluation of 'foreach'
expression '#body('Get_Library_List_Contents')' is of type 'Object'.
The result must be a valid array.
I don't think you can return an array back to PowerApps. You would have to return the response as a JSON string, then have your PowerApp do the logic to convert the JSON string into a collection.
Likely your PowerApp would have to include something like this to convert the JSON string that's returned from the flow:
ClearCollect(
*collectionName*,
MatchAll(
*JSON_String*,
*"\{""date"":""(?<date>[^""]*)"",""message"":""(?<message>[^""]*)"",""user"":""(?<user>[^""]*)""\}"*
));
Flow returning response body to PowerApp
If I understand you correctly, you want to retrieve 14000 records from the Sharepoint list, and not just the total count.
Would this mean I don't have to worry about Delegation if the list has more than 2000 items?
Yes, when you use a cloud flow rather than directly accessing Sharepoint list from Powerapps, you basically avoid delegation of 2k records.
Now coming back to you main topic of retrieving Records, you would have to Test and run your flow and check what does the below http return. I believe it returns a JSON Array.
concat( '_api/web/lists/GetbyTitle(''', first( body('Filter_Library_List_Being_Queried') )?['displayName'], ''')/Items' )
You would have to apply a for each or clean your JSON output to return String Array or JSON Array as output of your all 14K Records.
In addition if you are using Sharepoint online why not use connector for flow mentioned here
I have a pretty complex JSON object that contains, among other things, some JSON arrays that I need to update, removing and adding elements.
To do that I'm trying to use a JsPath that point directly to the object inside the array that I need to remove, something like:
/priceLists(1)/sections(0)/items(0)
to remove the element I tried to use json.prune and it doesn't work, I get this error: error.expected.jsobject
Would would be the best way to do that?
Your question is lacking a precise context (i.e., structure of your json data), but let's do with what we have.
The error message you get is clear, you can only call prune on a json object, to prune one of its values. You can't use it to prune an element of a json array.
I can only advise you to use json.update, stating that like prune, update only works on json objects. In the body of the update, work on your arrays as you usually do with scala/java data types.
__.json.update(__.reads[JsArray].map { jsArray =>
val removedElement = JsArray(jsArray.value.filter(_ == ???))
val addedElement = removedElement :+ JsBoolean(true)
addedElement
})
I have questions about JSON returning from the server using the Microsoft oData API.
Cannot figure it out.
Query1:
http://localhost:63717/odata/City(1)
Fiddler returns the raw data below.
Everything is in its own brackets.
{
"odata.metadata":"http://localhost:63717/odata/$metadata#City/#Element","CityID":1,"CityName":"Minnetonka","CityAddr1":null,"CityAddr2":null,"CityCity":null,"CityState":null,"CityZip":null,"CityPhone":null,"CityFAX":null,"CityExtent":"-93.53,44.88,-93.39,44.93","CityHeaderImage":null
}
Query2:
http://localhost:63717/odata/City?$filter=CityName eq 'Minnetonka'
Fiddler returns the raw data below.
Data is in two sets of bracketed data
{
"odata.metadata":"http://localhost:63717/odata/$metadata#City","value":[
{
"CityID":1,"CityName":"Minnetonka","CityAddr1":null,"CityAddr2":null,"CityCity":null,"CityState":null,"CityZip":null,"CityPhone":null,"CityFAX":null,"CityExtent":"-93.53,44.88,-93.39,44.93","CityHeaderImage":null
}
]
}
What do I have to do to format my JSON coming back for $filters in the oData request?
That odata.metadata is killing me in Query2.
Please explain what I am doing wrong.
In the first example, you have just one City element (denoted by City(1) in the request and #City/#Element in the result path).
In the second example, the value property in result is showing an array of City types (a listing of one or more objects). [ ... ] denotes an array in JavaScript. For a $filter type query, this is what I would expect. You can also see that the response path is less specific (#City instead of #City/#Element).
The path shown in the odata.metadata property value describes the structure of the element being returned, as I showed two examples above. The format of the return data will change depending on how you request it.
If you're having trouble parsing the JSON returned, consider using a library to do the heavy lifting for you. For example:
datajs
JayData
Breeze.js
[Source]
You are not doing anything wrong, the two formats actually represent two different forms of result.
The first you are requesting a single item as you are specifying the key for the entity.
In the second you are potentially asking for a list of entities. The Odata.Metadata is separate in this response otherwise it would be repeated for every item returned and would be a waste in terms of content length.
Because of the way that you are addressing the entity.
With //localhost:63717/odata/City(1) you are addressing one entity ("/entityset/key"). You will always return back one City (if one exists). There is no need for it to return an array because it will never return more than one.
With //localhost:63717/odata/City you are addressing a collection of entities ("/entityset"). 0 to n City entities could be returned, hence the need for a collection.
In ZF1 it was pretty easy to send a json boolean response, for example, in the controller use:
return $this->_helper->json(true);
What's the easiest way to repeat this in ZF2?
I tried creating a new JsonModel with an array of variables. The only entry in the array was my boolean value (with a key of 0). This didn't work because the resolver was still off looking for a template.
I think I somehow need to return early?
EDIT:
I think this is a really important issue. For example, when the JQ Validation plugin uses a server-side validation method, it expects a JSON boolean response.
I managed to make my application JSON-ready by following 'alternate rendering and response strategies' section at the bottom of the Zend\View page, http://framework.zend.com/manual/2.0/en/modules/zend.view.quick-start.html. But this operates on the array that has been passed to the view, so the boolean true becomes json [true]
I tried the json view helper in various combinations, but couldn't get it to work.
Perhaps I need to create my own rendering and response strategies? That seems like overkill though...
Rob Allen has written an article about it:
Returning JSON from a ZF2 controller action
Also you can try this code to return every data without view rendering:
$response = $this->getResponse();
$response->setStatusCode(200);
$response->setContent('some data');
return $response;
The easiest way:
echo "true";
exit;
Though you may want to output some appropriate headers.
Arguably the correct way would be to add the JsonStrategy as viewstrategy and use a JsonModel, but I think it always returns an object (the json_encoded associative array of view variables passed to the JsonModel).
I have a data which are object array. It contains object arrays in a tree structure. I use JSON.stringify(myArray) but the data still contain array because I see [] inside the converted data.
In my case, I want all the data to be converted into json object not array regarding I need to used the data on TreeTable of SAPUI5.
Maybe I misunderstand. Please help me clear.
This is the example of the data that I got from JSON.stringify.

JSON.stringify merely converts JavaScript data structures to a JSON-formatted string for consumption by other parsers (including JSON.parse). If you want it to stringify to a different value, you must change the source data structures first.
However, it seems that this can't be represented as anything other than an array because you have duplicate keys (i.e. value appears more than once). That would not be valid for a JavaScript object or a JSON representation of such.
I think what you want is
JSON.stringify(data[0]);
or perhaps
JSON.stringify(data[0].value);
where data is the object you passed in the question
