To efficiently construct and add a JSON object or array to your request body, use

...

PRIM_

...

JSON.Writer.

It's essential that you use XPRIMPRIM_JsonWriter JSON.Writer when your JSON data is big (instead of directly instantiating multiple XPRIMPRIM_JsonObject JSON.Object or XPRIMPRIM_JsonArrayJSON.Array), as XPRIMPRIM_JsonWriter JSON.Writer is designed to perform better for big data.


     Define_Com Class(#XPRIM#PRIM_HttpRequestSRVM.HttpClientRequest) Name(#Req)

* Create an XPRIM_JsonWriter a PRIM_JSON.Writer to efficiently write JSON data

       Define_Com Class(#XPRIM#PRIM_JsonWriterJSON.Writer) Name(#JsonWriter)

* Set the writer to output the JSON to the HTTP request object

 Textwriter(#StringWriter)
      #JsonWriter.SetOutputToHttpRequest HttpRequest(#ReqDefine_Com Class(#PRIM_IOC.StringWriter) Name(#StringWriter)

* Start constructing the object

       #JsonWriter.BeginObject
     #JsonWriter.WriteString NameMembername('givenName') Value(#EmpGivenName)
     #JsonWriter.WriteString NameMembername('lastName') Value(#EmpLastName)
     #JsonWriter.WriteString NameMembername('address') Value(#EmpAddress)
     #JsonWriter.EndObject

     #Req.Content.AddString Value(#StringWriter.Text)

* Execute the request


       #Req.DoPost Url('http://yourcompany.com/api/hr/employee')
