Issue with the JSON String from JSON Service

Posted on by Ian Lavadia

Hi All,

I have a problem when deserializing the JSON String thrown by the D365FO using the JSON Service. I tried setting the header to Accept application/json.

The class attached to the service:

[AifCollectionType('return', Types::RString, extendedTypeStr(Name))]

public anytype processData(ContractOfJsonReceived jReceived)

// Process Data

ContractOfJsonReturn jReturn;

str JSonStr = FormJsonSerializer::serializeClass(jReturn);

By that way, the application I'm using to simulate pushing of data is Postman. And I do understand that people here would push me to develop this using NewtonSoft.JSON.Net on C# yet I want to know the workaround for this. Thank you

You said you had a problem, but it's not clear to me what kind of problem.

If you want to serialize the string to objects but you refuse to use the library doing exactly that, then what do you really want?

Hi Martin,

Sorry I wasn't able to describe more about my problem. The problem I encounter is that the response I received was enclosed with double quotes and the postman interprets it as a string. I'm hoping I can receive it as a JSON Object.

Example:

"{\"Number Sequence\":123,\"Reference Number\":\"IHL | RMF-RAFI-PAY-RFP-000000236\"}"

What I want to achieve is having a result of

{

"Number Sequence":123,

"Reference Number":"IHL-00002"

}

A service operation returns data, which is then returned by the web service in JSON. Typically the data is a contract object and the web service returns this object serialized to JSON. But not in your case - instead of returning an object, you explicitly serialize it to a string and you return this string, therefore you get this string wrapped in JSON.

The solution is throwing away your code with FormJsonSerializer and returning jReturn object directly. You'll also have to change the return type to ContractOfJsonReturn. And throw away AifCollectionType, because you're not returning a collection (such as a list of contract objects).
