OpenTelemetry TraceResponse Propagator
======================================

[](#opentelemetry-traceresponse-propagator)

**Note:** This package is experimental as `traceresponse` is currently an editors' draft.

This package provides a [Trace Context HTTP Response Headers Format](https://w3c.github.io/trace-context/#trace-context-http-response-headers-format)propagator to inject the current span context into Response datastructures.

The main goal is to allow client-side technology (Real User Monitoring, HTTP Clients) to record the server side context in order to allow referencing it.

Requirements
------------

[](#requirements)

- OpenTelemetry SDK and exporters (required to actually export traces)

Optional:

- OpenTelemetry extension (Some instrumentations can automatically use the `TraceResponsePropagator`)

Usage
-----

[](#usage)

Assuming there is an active `SpanContext`, you can inject it into your response as follows:

```
// your framework probably provides a datastructure to model HTTP responses
// and allows you to hook into the end of a request / listen to a matching event.
$response = new Response();

// get the current scope, bail out if none
$scope = Context::storage()->scope();
if (null === $scope) {
    return;
}

// create a PropagationSetterInterface that knows how to inject response headers
$propagationSetter = new class implements OpenTelemetry\Context\Propagation\PropagationSetterInterface {
    public function set(&$carrier, string $key, string $value) : void {
        $carrier->headers->set($key, $value);
    }
};
$propagator = new TraceResponseProgator();
$propagator->inject($response, $propagationSetter, $scope->context());
```

Installation via composer
-------------------------

[](#installation-via-composer)

```
$ composer require open-telemetry/opentelemetry-propagation-traceresponse
```

Installing dependencies and executing tests
-------------------------------------------

[](#installing-dependencies-and-executing-tests)

From TraceResponse subdirectory:

```
$ composer install
$ ./vendor/bin/phpunit tests
```
