I'm not sure how to actually interact with the result set I get from doing something like this. I want to return something like:

[{"field1":1, "field2":2}, {"field1":2, "field2":10}]

I'm finding it very difficult to get it in this format, since %Print appends a newline onto the end of the {} object it prints.

Here's the closest I've gotten:

Dear Colleagues and Friends,

is there any indication that the .NET object representation of Cache objects (i.e. InterSystems.Data.CacheClient.dll) complies with .NET Standard? I'm planning to extend our existing .NET client/server solution with a mobile option by Xamarin Forms and can't find any significant hints in the internet.

I'm just fooling around a bit and made some expreiments with a REST API and a generic object-to-JSON tier:

JSON challenge

Hello folks,

I have an JSON object that need to be updated before being parsed into a JSX component.

Source JSON obj:

var Obj = { "data": [
  {"id":1, "text":"Task #1", "project":"10", "sub_project":"10-1" },
  {"id":2, "text":"Task #2", "project":"10", "sub_project":"10-1" },
  {"id":3, "text":"Task #3", "project":"11", "sub_project":"11-1" },
]};

Required JSON obj result:

Hi All,

I am trying to get JSON data from a REST api. I am using my web browser to get the data by hitting the URL.

The data is receiving properly, but the JSON contains a few HTML tags.

These tags are not not receiving in the browser while hitting the url. Is there any way to overcome this issue ?

Thanks,

Hi all,

I have an incoming JSON message with a string field exceeding in length the 'caché long-string limit' of 3641144 characters.

Using {}.%FromJSON(instream) I am able to create %DynamicObject properly. However, I am unable to access the long property, as in every assignment, I get the <MAXSTRING> error.

Is there any way for me to obtain contents of the 'too long' string field as a stream?

Thanks

Jiri

When using the JSON_OBJECT() function in Caché SQL on a %String property that contains JSON syntax, it converts the %String into a JSON object instead of escaping it as a string literal. How can I prevent this? (without ridiculous hacks like "add a space to the beginning of the value" as we don't always know which properties will contain these values and I certainly don't want to have to check for nulls and add/remove a space every single place this value is used in the application)

I don't want these strings automatically marshalled into JSON objects.

For example:

I am trying to use the automated unittest class for a %CSP.Rest service.

So my Unittest code set's %request and %response from %CSP.Req/resp respectively

I build a tProxy with the fields I need for the post and set it %ToJson... I have tried seting %request.Content = tProxy (and not)

I call the method for the post url directly...

When that method calls %fromJson to set an object with the info. I passed...

- when I don't set %request.content.. I get a error '5035 - premature end of data code 12'

Recently, a partner company started to develop an Angular client for their Cache application. Together, we decided to leverage the power of Caché dynamic objects to exchange JSON encoded data between client and server parts. However, we realized that currently there is a gap in Cache JSON implementation that prevents simple use of traditional registered and persistent classes to exposed their data with the same ease as with XML. I wrote a small JSON adapter, that does the job and bridgers the gap. It's purpose is simple expose data described by a regular Cache class in a one-to-one fashion to a %DynamicObject. On the other hand, when a serialized JSON data comes in, it can be easily deserialized into dynamic object and subsequently bound to regular class by the newly created adapter.

Hi everyone,

I need submit a object have a json string as property of class, but I get an issue, object can't save to SQL table if I take json data to json property. I try making a test class with only json property and get the same issue, no data row in SQL table after run ClassMethod . Some one know what's problem, please help me. Here my test class:

0 816
404 Not Found

{
"error": {
 "errors": [
  {
   "domain": "global",
   "reason": "notFound",
   "message": "Not Found"
  }
 ],
 "code": 404,
 "message": "Not Found"
 }
}

I want to do something like the above sample from a Google Storage JSON API. I have a call to Write obj.%ToJSON() followed by return ..ReportHttpStatusCode(..#HTTP404NOTFOUND) however the HTTP Status code is always 200. If I remove the Write obj.%ToJSON() statement it returns a 404 status with no body. How do I return both?

Generally speaking, InterSystems products supported dynamic objects and JSON for a long while, but version 2016.2 came with a completely new implementation of these features, and the corresponding code was moved from the ObjectScript level to the kernel/C level, which made for a substantial performance boost in these areas. This article is about innovations in the new version and the migration process (including the ways of preserving backward compatibility).

or "Didn't you say you would cover Persistent Objects in Part 5, Chris?"

Yes, that was the plan. This is a pretty important topic, so it get's its own Article

Up until now, we've display widget JSON that has been created by a basic loop. Clearly this isn't of much value. Now we have our stack connected together, and we can see that the data is flowing to the Welcome page, it's time to complete the stack and start feeding our service from "real" data.

Hi everyone,

I am still learning the platform for a student project and have to do some streaming and data analysis next. Since for my case I have no "live api" I wanted to just stream json files and output the data as it comes in from the files. (basically to emulate a incoming data scenario)

So thanks to the documentation and community posts I have figured how to create a stream and read data from a JSON but since I'm also new to JSON I have some parsing problems. I don't know how to access subarrays/sub-objects via objectscript.
