Description
Sets the value for a key. If the key does not exist, then create the key and set its value. If the key already exists, then overwrite the value of this key. If more than one key with the same name already exists, then overwrite the value of the first key. Notice that the IgnoreCase property (true by default) determines whether the key name will be matched in a case-sensitive manner.

Examples
This example packages the JSON data and a string and then sends the package to the server:
int li_rc
string ls_json, ls_EmployeeJson, ls_ReturnJson
HttpClient lnv_HttpClient
JsonPackage lnv_package
lnv_HttpClient = create HttpClient
lnv_package = create JsonPackage
ls_EmployeeJson = dw_employee.ExportJson(false)
// Package the data
lnv_package.SetValue("d_employee ", ls_EmployeeJson)
lnv_package.SetValue("MyString", "Test String", false)
ls_json = lnv_package.GetJsonString()
// Construct a POST request
lnv_HttpClient.SetRequestHeader("Content-Type", "application/json;charset=UTF-8")
// Send the package to the server
li_rc = lnv_HttpClient.SendRequest("POST", "http://demo.appeon.com/PB/webapi_client/postJsonpackage/employee", ls_json)
// Get the data
if li_rc = 1 and lnv_HttpClient.GetResponseStatusCode() = 200 then
lnv_HttpClient.GetResponseBody(ls_ReturnJson, EncodingUTF8!)
else
MessageBox("Error", "Failed to call service.")
end ifThis example packages the data of the DataWindow, DataStore and DataWindowChild controls and then sends the package to the server:
