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. Tcl

load ./chilkat.dll

set success 0

# 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}}
set targetCurl "curl -X GET https://httpbin.org/{{verb}}?id={{id_value}}"

set httpCurl [new_CkHttpCurl]

# Provide values for variables.
# In this example, "verb" is a path variable, and "id_value" is a query param variable.
CkHttpCurl_SetVar $httpCurl "verb" "get"
CkHttpCurl_SetVar $httpCurl "id_value" "123"

# Run the curl command.
set success [CkHttpCurl_DoYourThing $httpCurl $targetCurl]
if {$success == 0} then {
    puts [CkHttpCurl_lastErrorText $httpCurl]
    delete_CkHttpCurl $httpCurl
    exit
}

set responseJson [new_CkJsonObject]

CkJsonObject_put_EmitCompact $responseJson 0

set statusCode [CkHttpCurl_get_StatusCode $httpCurl]
puts "response status code: $statusCode"

CkHttpCurl_GetResponseJson $httpCurl $responseJson
puts [CkJsonObject_emit $responseJson]

# Output:

# response status code: 200
# {
#   "args": {
#     "id": "123"
#   },
#   "headers": {
