![]() ![]() This will mean that resources are encoded using exactly the same schemas as are used in your API's HTTP responses. You can use the JSON API configuration for your application's JSON API's to send requests to an external location. By using the client implementation in this package, you can serialize and send records to theĮxternal webhook in the same format that they would be encoded in your API's HTTP responses. Guzzle 6 and you will need to install Guzzle via Composer: composer require guzzlehttp/guzzle:^6.3Īn example use case for this feature is where your API sends events to external webhooks, like the StripeĪPI. Resource schemas to serialize records and send them as outbound HTTP requests. It includes a client implementation that allows you to re-use your If you use RESTful routing controllers, that might be a nice addition, similar to how Rails lets you set a return type.This package is primarily concerned with your application acting as a JSON API server. ![]() This is ripe for some sort of middleware or other functionality which automatically can decide to return JSON or HTML (or hey, even XML!). I suggest taking a look at some of the shortcuts the Laravel Request class has - you can check for other content types with the accepts() method, for example, or use the prefers() method to see which is the most prefered content type. If you want to see if the request will accept JSON, regardless of it's set preference, use the acceptsJson() method. It's not simply saying "Yeah, I guess JSON was one of the content types you wanted". Note that this is grabbing the first of the list of acceptable content types, ordered by preference, sent in the HTTP request and testing if it is a JSON content type. Return isset($acceptable) & Str::contains($acceptable, ) $acceptable = $this->getAcceptableContentTypes() If you check out the function linked above, you can see how Laravel is using the underlying Symfony HTTP classes, which handle the dirty work of knowing that HTTP requests might send down multiple accept content types: public function wantsJson() Hello, global function! We sincerely love you with all our wantsJson() ) Look at this nice, friendly global helper function Laravel provides a nice, easy way to check if a request "wants json": Route::get('/foo', function() Return // Returns JSON, thanks to Laravel Magic™ $accept = request()->header('accept') // application/json If you want to check for that header, you can do some manual stuff: Route::get('/foo', function() Not much of a negotiation, if you ask me.įor example, if a request comes into your Laravel app with an Accept header requesting JSON, you can totally ignore it without ever realizing the HTTP client wanted something else: Route::get('/foo', function() The server then can decide what it's willing/able to send back. The client says what content types it's willing to accept, and its preference. When a request comes to our application, it's pretty easy to ignore these rules, as our frameworks generally let us return whatever we want. It's up to the server to follow the rules of HTTP. I won't get any more into that, but your can read more about it in the HTTP spec. This is essentially telling the server the ordered preference of content types it wants back. ![]() The above example lists a few media types the client (Chrome) is willing to accept, and even gives them a "quality" factor (the q rating, value 0-1). In a typical request from Chrome, we see something more like this: Accept:text/html,application/xhtml+xml,application/xml q=0.9,image/webp,*/* q=0.8Īs you can see, the Accept header can get complex. ![]() Such a header might look something like this: Accept: application/json Types which are acceptable for the response. The Accept request-header field can be used to specify certain media This header is meant to tell the server what content types it is willing to accept. Here's a little bit about content negotiation.Īn HTTP client, such as your browser, or perhaps jQuery's ajax method, can set an Accept header as part of an HTTP request. ![]()
