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. Chilkat2 PHP

<?php

use Chilkat2\HttpCurl;
use Chilkat2\StringBuilder;

// 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 = new StringBuilder();
$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 = new HttpCurl();

// 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 = new StringBuilder();
try {
    $curl->ToRawRequest($sbCurl->GetAsString(), $sbRawRequest);
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

echo $sbRawRequest->GetAsString(), "\n";

// 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->EnableBodyVars = false;

try {
    $curl->ToRawRequest($sbCurl->GetAsString(), $sbRawRequest);
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

echo $sbRawRequest->GetAsString(), "\n";

// The raw request with body variable substitution disable:

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