(PHP ActiveX) Debug REST HTTP Request

Demonstrates how to generate the HTTP Request (with all headers intact) without actually sending the request.

Note: This example requires Chilkat v9.5.0.77 or later.

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 will connect to the web server, but does not actually send a request.
// When in DebugMode, the request is composed in memory and can be retrieved by calling
// GetLastDebugRequest.

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

// Connect Code...
// URL: https://test-api.service.hmrc.gov.uk/organisations/vat/MY_HMRC_VRN/returns
$bTls = 1;
$port = 443;
$bAutoReconnect = 1;
$success = $rest->Connect('test-api.service.hmrc.gov.uk',$port,$bTls,$bAutoReconnect);
if ($success != 1) {
    print 'ConnectFailReason: ' . $rest->ConnectFailReason . "\n";
    print $rest->LastErrorText . "\n";
    exit;
}

// Build the request body...
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.JsonObject')
$json = new COM("Chilkat.JsonObject");
$json->UpdateString('periodKey','A001');
$json->UpdateNumber('vatDueSales','105.50');
$json->UpdateNumber('vatDueAcquisitions','-100.45');
$json->UpdateNumber('totalVatDue','5.05');
$json->UpdateNumber('vatReclaimedCurrPeriod','105.15');
$json->UpdateNumber('netVatDue','100.10');
$json->UpdateInt('totalValueSalesExVAT',300);
$json->UpdateInt('totalValuePurchasesExVAT',300);
$json->UpdateInt('totalValueGoodsSuppliedExVAT',3000);
$json->UpdateInt('totalAcquisitionsExVAT',3000);
$json->UpdateBool('finalised',1);

// Add Headers...
$rest->AddHeader('Accept','application/vnd.hmrc.1.0+json');
$rest->AddHeader('Authorization','Bearer HMRC_ACCESS_TOKEN');
$rest->AddHeader('Content-Type','application/json');

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringBuilder')
$sbRequestBody = new COM("Chilkat.StringBuilder");
$json->EmitSb($sbRequestBody);

// Set DebugMode so that no request is actually sent.
$rest->DebugMode = 1;

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringBuilder')
$sbResponseBody = new COM("Chilkat.StringBuilder");
$success = $rest->FullRequestSb('POST','/organisations/vat/MY_HMRC_VRN/returns',$sbRequestBody,$sbResponseBody);
if ($success != 1) {
    print $rest->LastErrorText . "\n";
    exit;
}

// Get the exact contents of what would've been sent.
// This includes the HTTP start line, the HTTP request headers, and the request body.
// Given that it's possible for the request body to contain binary data,
// the GetLastDebugRequest fetches into a BinData object.
// In this case, however, our request body contained JSON, so we can
// examine it as a string..
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.BinData')
$bdRequest = new COM("Chilkat.BinData");
$success = $rest->GetLastDebugRequest($bdRequest);

print '----' . "\n";
print $bdRequest->getString('utf-8') . "\n";
print '----' . "\n";

// The output for the above case:

// POST /organisations/vat/MY_HMRC_VRN/returns HTTP/1.1
// Accept: application/vnd.hmrc.1.0+json
// Host: test-api.service.hmrc.gov.uk
// Authorization: Bearer HMRC_ACCESS_TOKEN
// Content-Type: application/json
// Content-Length: 281
// 
// {"periodKey":"A001","vatDueSales":105.50, ... ,"finalised":true}
