See more REST Examples

When passing a path to a Chilkat REST function, the path parts and query params should be URL encoded. This example explains..

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

<?php

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// This example demonstrates how to URL encode the path passed to a REST function.
// It is demonstrated with an Amazon SP API GET request to get details about a listings item for a selling partner.
// See https://developer-docs.amazon.com/sp-api/docs/listings-items-api-v2021-08-01-reference#getlistingsitem

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Rest')
$rest = new COM("Chilkat.Rest");

// Connect to the REST server.
$bTls = 1;
$port = 443;
$bAutoReconnect = 1;
$success = $rest->Connect('sellingpartnerapi-eu.amazon.com',$port,$bTls,$bAutoReconnect);

$rest->ClearAllQueryParams();
$rest->AddQueryParam('marketplaceids','XYZABC123');
$rest->AddQueryParam('includedData','offers');

$rest->AddHeader('x-amz-access-token','YOUR_ACCESS_TOKEN');

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.AuthAws')
$authAws = new COM("Chilkat.AuthAws");
$authAws->AccessKey = 'YOUR_AWS_APP_ID';
$authAws->SecretKey = 'YOUR_AWS_APP_SECRET_KEY';
$authAws->Region = 'eu-west-1';
$authAws->ServiceName = 'execute-api';
$rest->SetAuthAws($authAws);

// The path that is passed to FullRequestNobBody

// Here's a sample path that is not yet URL encoded.
$path = '/listings/2022-07-01/items/ABCDEFGHIJ/100x100_28g_LANCETS(BOXED)';

// The path passed to FullRequestNoBody needs to have the parts URL-encoded.
// The "/" chars are not URL encoded, but the individual path parts should be URL encoded.
// For example:  /listings/2022-07-01/items/ABCDEFGHIJ/100x100_28g_LANCETS%28BOXED%29

// In this case, we'll prepare the path like this:
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringBuilder')
$sbPath = new COM("Chilkat.StringBuilder");
$sbPath->Append('100x100_28g_LANCETS(BOXED)');
// URL encode the contents of the sbPath.
$sbPath->Encode('url','utf-8');
// Prepend the remaining which does not need to be URL encoded.
$sbPath->Prepend('/listings/2022-07-01/items/ABCDEFGHIJ/');

print 'URL encoded path: ' . $sbPath->getAsString() . "\n";

$responseJson = $rest->fullRequestNoBody('GET',$sbPath->getAsString());
if ($rest->LastMethodSuccess != 1) {
    print $rest->LastErrorText . "\n";
    exit;
}

print $responseJson . "\n";
print '----' . "\n";
