(VB.NET UWP/WinRT) HTTP POST JSON (application/json)Demonstrates how to send a JSON POST using the application/json content-type.
' This example requires the Chilkat API to have been previously unlocked. ' See Global Unlock Sample for sample code. Dim req As New Chilkat.HttpRequest Dim http As New Chilkat.Http ' If any custom headers need to be included with the POST, add them ' by calling SetRequestHeader ' Note: An application should never explicitly set the Content-Length header. ' The Content-Length is automatically computed and added by Chilkat. ' Here are some examples of custom headers. ' Perhaps your particular app needs some sort of custom-computed Authorization header... http.SetRequestHeader("Authorization","my-custom-computed-auth-value") ' Another custom header for some hypothetical app: http.SetRequestHeader("X-Pass-Timestamp","my-custom-computed-timestamp-value") ' We don't need to set the Content-Type header, becaue it is automatically set by Chilkat ' in the PostJson2 call below. ' The following "Accept" header may be set, but it really isn't necessary: http.SetRequestHeader("Accept","application/json") Dim jsonText As String = "{ some JSON text ... }" ' To use SSL/TLS, simply use "https://" in the URL. Dim resp As Chilkat.HttpResponse resp = Await http.PostJson2Async("http://www.someserver.com/someJsonEndpoint","application/json",jsonText) If (http.LastMethodSuccess <> True) Then Debug.WriteLine(http.LastErrorText) Else ' Display the JSON response. Debug.WriteLine(resp.BodyStr) End If |
