Duplicate curl -u user:password with Chilkat HTTP

See more HTTP Misc Examples

Demonstrates how to duplicate a curl command that uses the -u username:password option. (This assumes HTTP Basic Authentication, and Chilkat requires Basic authentication to be over a TLS connection.)

Duplicates the following curl command:

curl https://api.sandbox.paypal.com/v1/oauth2/token \
  -H "Accept: application/json" \
  -H "Accept-Language: en_US" \
  -u "Client-Id:Secret" \
  -d "grant_type=client_credentials"

Dim success As Boolean = False

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

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

'  The AddHeader method corresponds to the curl "-H" argument.
req.AddHeader("Accept", "application/json")
req.AddHeader("Accept-Language", "en_US")

'  The curl "-d" argument specifies the HTTP request body.  In this case,
'  we're sending an application/x-www-form-urlencoded request, and therefore
'  the body contains the URL-encoded query parameters.
req.AddParam("grant_type", "client_credentials")

http.Login = "PAYPAL_REST_API_CLIENT_ID"
http.Password = "PAYPAL_REST_API_SECRET"

'  Sends a POST request where the Content-Type is application/x-www-form-urlencoded
req.HttpVerb = "POST"
req.ContentType = "application/x-www-form-urlencoded"

Dim resp As ChilkatHttpResponse
resp.Initialize
success = http.HttpReq("https://api.sandbox.paypal.com/v1/oauth2/token", req, resp)
If success = False Then
    Log(http.LastErrorText)
    Return
End If


If resp.StatusCode <> 200 Then
    Log("Error status code: " & resp.StatusCode)
    Log(resp.BodyStr)
    Return
End If


'  The JSON response is in the resp BodyStr property
Log(resp.BodyStr)
Log("-- Success.")
