CkPython Requires Chilkat v11.5.0+

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. CkPython

import sys
import chilkat

success = 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}}}'

sbCurl = chilkat.CkStringBuilder()
sbCurl.AppendLn("curl -X POST https://api.example.com/data \\")
sbCurl.AppendLn("  -H \"Content-Type: application/json\" \\")
sbCurl.AppendLn("  -d '{\"name\":\"{{name}}\",\"age\":{{age}}}'")

curl = chilkat.CkHttpCurl()

#  Provide values for variables.
curl.SetVar("name","Alice")
curl.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.
sbRawRequest = chilkat.CkStringBuilder()
success = curl.ToRawRequest(sbCurl.getAsString(),sbRawRequest)
if (success == False):
    print(curl.lastErrorText())
    sys.exit()

print(sbRawRequest.getAsString())

#  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

curl.put_EnableBodyVars(False)

success = curl.ToRawRequest(sbCurl.getAsString(),sbRawRequest)
if (success == False):
    print(curl.lastErrorText())
    sys.exit()

print(sbRawRequest.getAsString())

#  The raw request with body variable substitution disable:

#  Host: api.example.com
#  Content-Type: application/json
#  Content-Length: 33
#  
#  {"name":"{{name}}","age":{{age}}}
