curl with Path Variables and Query Param Variables

See more CURL Examples

This example demonstrates using variables located in the path and query params with the {{variable_name}} syntax. VB.NET

Dim success As Boolean = False

' Variables can occur in the path and query params.  
' Variable names are enclosed between {{ and }}

'  curl -X GET https://httpbin.org/{{verb}}?id={id_value}}
Dim targetCurl As String = "curl -X GET https://httpbin.org/{{verb}}?id={{id_value}}"

Dim httpCurl As New Chilkat.HttpCurl

' Provide values for variables.
' In this example, "verb" is a path variable, and "id_value" is a query param variable.
httpCurl.SetVar("verb","get")
httpCurl.SetVar("id_value","123")

' Run the curl command.
success = httpCurl.DoYourThing(targetCurl)
If (success = False) Then
    Debug.WriteLine(httpCurl.LastErrorText)
    Exit Sub
End If


Dim responseJson As New Chilkat.JsonObject
responseJson.EmitCompact = False

Dim statusCode As Integer = httpCurl.StatusCode
Debug.WriteLine("response status code: " & statusCode)

httpCurl.GetResponseJson(responseJson)
Debug.WriteLine(responseJson.Emit())

' Output:

' response status code: 200
