curl with Variable Substitution in the Request Body

See more CURL Examples

This example demonstrates using variables located in the request body with the {{variable_name}} syntax. AutoIt

Local $bSuccess = False

;  Variables can also be used within the HTTP request body.
;  Variable names are enclosed between {{ and }}

;  Here is a curl command with two variables {{name}} and {{age}} located in the data.

;  curl -X POST https://api.example.com/data \
;    -H "Content-Type: application/json" \
;    -d '{"name":"{{name}}","age":{{age}}}'

$oSbCurl = ObjCreate("Chilkat.StringBuilder")
$oSbCurl.AppendLn("curl -X POST https://api.example.com/data \")
$oSbCurl.AppendLn("  -H ""Content-Type: application/json"" \")
$oSbCurl.AppendLn("  -d '{""name"":""{{name}}"",""age"":{{age}}}'")

$oCurl = ObjCreate("Chilkat.HttpCurl")

;  Provide values for variables.
$oCurl.SetVar "name","Alice"
$oCurl.SetVar "age","30"

;  To demonstrate how the variables are replaced, this example does not execute the curl command. 
;  Instead, it generates the raw HTTP request that would be sent if the curl command were run.
$oSbRawRequest = ObjCreate("Chilkat.StringBuilder")
$bSuccess = $oCurl.ToRawRequest($oSbCurl.GetAsString(),$oSbRawRequest)
If ($bSuccess = False) Then
    ConsoleWrite($oCurl.LastErrorText & @CRLF)
    Exit
EndIf

ConsoleWrite($oSbRawRequest.GetAsString() & @CRLF)

;  Output:

;  POST /data HTTP/1.1
;  Host: api.example.com
;  Content-Type: application/json
;  Content-Length: 25
;  
;  {"name":"Alice","age":30}

;  Note: Variable substitution in the request body can be turned off by 
;  setting the EnableBodyVars property equal to False

$oCurl.EnableBodyVars = False

ConsoleWrite($oSbRawRequest.GetAsString() & @CRLF)

;  The raw request with body variable substitution disable:

;  Content-Type: application/json
;  Content-Length: 33

;  {"name":"{{name}}","age":{{age}}}
