HTTP POST JSON (application/json)

See more HTTP Examples

Demonstrates how to send a JSON POST using the application/json content-type. B4X

Dim success As Boolean = False

'  This example requires the Chilkat API to have been previously unlocked.
'  See Global Unlock Sample for sample code.

Dim req As ChilkatHttpRequest
req.Initialize
Dim http As ChilkatHttp
http.Initialize("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")

'  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 ChilkatHttpResponse
resp.Initialize
success = http.HttpStr("POST", "http://www.someserver.com/someJsonEndpoint", jsonText, "utf-8", "application/json", resp)
If success = False Then
    Log(http.LastErrorText)
    Return
End If



'  Display the JSON response.
