Of course, all routes and controllers should return some kind of response to be sent back to the user's browser. Lumen provides several different ways to return responses. The most basic response is simply returning a string from a route or controller:.

Returning a full Response instance allows you to customize the response's HTTP status code and headers. Keep in mind that most response methods are chainable, allowing for the fluent building of responses. For example, you may use the header method to add a series of headers to the response before sending it back to the user:. Or, you may use the withHeaders method to specify an array of headers to be added to the response:. The response helper may be used to conveniently generate other types of response instances.
This class provides several helpful methods for generating responses.Ligier js50 uk
The download method may be used to generate a response that forces the user's browser to download the file at the given path. The download method accepts a file name as the second argument to the method, which will determine the file name that is seen by the user downloading the file.
Finally, you may pass an array of HTTP headers as the third argument to the method:. There are several ways to generate a RedirectResponse instance. The simplest method is to use the global redirect helper method:. For example, to generate a RedirectResponse to a named route, you may use the route method:. If your route has parameters, you may pass them as the second argument to the route method:. If you are redirecting to a route with an "ID" parameter that is being populated from an Eloquent model, you may simply pass the model itself.

For some reason Laravel seems to be manipulating the response headers 'Cache-Control' on the very last moment.Axios Crash Course - HTTP Library
I want to make browser caching possible. Even when I use a 'after-middleware' and die and dump the response, I still get this, what seems to be right to me. But when I receive the response, Firebug shows the following:. How can I achieve that the browser does not receive the Cache-Control headers "no-store, no-cache" when I set the last-modified and expires headers?
I have been struggling with cache-control in laravel on apache for a few days now: I found that setting the headers within laravel simply appended them on to the headers set by php. I tried setting up some rules in apache. In the end I settled for setting session. Although I do not know your exact configuration, I would assume that this is due to your Apache configuration, as header values can be overwritten there. Have a look through all Apache configuration files and look out for lines starting with Header Set Cache-Controle.
Probably such a directive is set to affect only your PHP files, which would be the reason why other files are delivered with other headers. However: Watch out when changing this. Maybe you would want this to be set for security reasons.

Checking the Referer is a commonly used method of preventing CSRF on embedded network devices because it does not require any per-user state.
This makes Referer a useful method of CSRF prevention when memory is scarce or server-side state doesn't exist. This method of CSRF mitigation is also commonly used with unauthenticated requests, such as requests made prior to establishing a session state which is required to keep track of a synchronization token. In both cases, just make sure the target origin check is strong. For example, if your site is "site.

Following a redirect cross-origin. In this situation, the Origin is not included in the redirected request because that may be considered sensitive information you don't want to send to the other origin. But since we recommend rejecting requests that don't have both Origin and Referer headers, this is OK, because the reason the Origin header isn't there is because it is a cross-origin redirect.

So instead of writing this for each and every route can it be done in global scope, so that headers are set for every view. Option 1 simple : Since the array is just static data - just manually put the headers in your view layouts directly - i. Option 2: Use view composers.
You can use an App before filter to bind the header to all views in your app. Note: you must let the view set your headers - that is why we are 'passing' the header into view for Laravel to handle.Download free books to read offline
If you try and output the header itself from within a filter or something, you'll cause issues. For future readers using Laravel 5. Laravel has the response helper method, which you can chain headers to very easily.

Active Oldest Votes. Laurence Laurence What is the use of passing headers to view?? But if for some reason you dont want to do that, you could 'pass' the headers into the view using a view composer. Are you talking about meta tags? When you "set headers" - all that is occuring is that text appears at the top of your html file. So you can either do that with a view composer, or just type it yourself at the top of the file.

Laravel provides several different ways to return responses. The most basic response is returning a string from a route or controller. The framework will automatically convert the string into a full HTTP response:. In addition to returning strings from your routes and controllers, you may also return arrays. The framework will automatically convert the array into a JSON response:. They will automatically be converted to JSON.
Give it a shot! Typically, you won't just be returning simple strings or arrays from your route actions. Returning a full Response instance allows you to customize the response's HTTP status code and headers. Keep in mind that most response methods are chainable, allowing for the fluent construction of response instances. For example, you may use the header method to add a series of headers to the response before sending it back to the user:. Or, you may use the withHeaders method to specify an array of headers to be added to the response:.
Laravel includes a cache. If etag is specified in the list of directives, an MD5 hash of the response content will automatically be set as the ETag identifier:. The cookie method on response instances allows you to easily attach cookies to the response.
For example, you may use the cookie method to generate a cookie and fluently attach it to the response instance like so:. The cookie method also accepts a few more arguments which are used less frequently. Generally, these arguments have the same purpose and meaning as the arguments that would be given to PHP's native setcookie method:.
Alternatively, you can use the Cookie facade to "queue" cookies for attachment to the outgoing response from your application. The queue method accepts a Cookie instance or the arguments needed to create a Cookie instance. These cookies will be attached to the outgoing response before it is sent to the browser:.
By default, all cookies generated by Laravel are encrypted and signed so that they can't be modified or read by the client. There are several ways to generate a RedirectResponse instance. The simplest method is to use the global redirect helper:.
Sometimes you may wish to redirect the user to their previous location, such as when a submitted form is invalid. You may do so by using the global back helper function. Since this feature utilizes the sessionmake sure the route calling the back function is using the web middleware group or has all of the session middleware applied:.
For example, to generate a RedirectResponse to a named route, you may use the route method:.Outdoor glider
If your route has parameters, you may pass them as the second argument to the route method:. If you are redirecting to a route with an "ID" parameter that is being populated from an Eloquent model, you may pass the model itself. The ID will be extracted automatically:. If you would like to customize the value that is placed in the route parameter, you should override the getRouteKey method on your Eloquent model:.The incoming request instance will automatically be injected by the service container :.
If your controller method is also expecting input from a route parameter you should list your route parameters after your other dependencies. For example, if your route is defined like so:. The service container will automatically inject the incoming request into the Closure when it is executed:.Itil foundation test exam
We will discuss a few of the most important methods below. The path method returns the request's path information. The is method allows you to verify that the incoming request path matches a given pattern. To retrieve the full URL for the incoming request you may use the url or fullUrl methods.
The url method will return the URL without the query string, while the fullUrl method includes the query string:. The method method will return the HTTP verb for the request. If you would like to obtain an instance of a PSR-7 request instead of a Laravel request, you will first need to install a few libraries. Once you have installed these libraries, you may obtain a PSR-7 request by type-hinting the request interface on your route Closure or controller method:. These middleware will automatically trim all incoming string fields on the request, as well as convert any empty string fields to null.
This allows you to not have to worry about these normalization concerns in your routes and controllers. You may also retrieve all of the input data as an array using the all method:. Regardless of the HTTP verb, the input method may be used to retrieve user input:.
You may pass a default value as the second argument to the input method. This value will be returned if the requested input value is not present on the request:.
When working with forms that contain array inputs, use "dot" notation to access the arrays:. You may call the input method without any arguments in order to retrieve all of the input values as an associative array:.
While the input method retrieves values from entire request payload including the query stringthe query method will only retrieve values from the query string:.
If the requested query string value data is not present, the second argument to this method will be returned:. You may call the query method without any arguments in order to retrieve all of the query string values as an associative array:.
For example, if one of your application's forms contains a name field, you may access the value of the field like so:. When using dynamic properties, Laravel will first look for the parameter's value in the request payload. If it is not present, Laravel will search for the field in the route parameters. You may even use "dot" syntax to dig into JSON arrays:.
When dealing with HTML elements like checkboxes, your application may receive "truthy" values that are actually strings. For example, "true" or "on". For convenience, you may use the boolean method to retrieve these values as booleans. The boolean method returns true for 1, "1", true, "true", "on", and "yes".
All other values will return false :. If you need to retrieve a subset of the input data, you may use the only and except methods. Both of these methods accept a single array or a dynamic list of arguments:. You should use the has method to determine if a value is present on the request. The has method returns true if the value is present on the request:. When given an array, the has method will determine if all of the specified values are present:. The hasAny method returns true if any of the specified values are present:.
If you would like to determine if a value is present on the request and is not empty, you may use the filled method:.Laravel's wrapper around Guzzle is focused on its most common use cases and a wonderful developer experience. Before getting started, you should ensure that you have installed the Guzzle package as a dependency of your application.
By default, Laravel automatically includes this dependency:. To make requests, you may use the getpostputpatchand delete methods. First, let's examine how to make a basic GET request:. So, these methods accept an array of data as their second argument. If you would like to send files as multi-part requests, you should call the attach method before making your request. This method accepts the name of the file and its contents. Optionally, you may provide a third argument which will be considered the file's filename:.
Headers may be added to requests using the withHeaders method.
You may specify basic and digest authentication credentials using the withBasicAuth and withDigestAuth methods, respectively:. If you would like to quickly add an Authorization bearer token header to the request, you may use the withToken method:.
The timeout method may be used to specify the maximum number of seconds to wait for a response:. If you would like HTTP client to automatically retry the request if a client or server error occurs, you may use the retry method. The retry method accepts two arguments: the number of times the request should be attempted and the number of milliseconds that Laravel should wait in between attempts:.
Unlike Guzzle's default behavior, Laravel's HTTP client wrapper does not throw exceptions on client or server errors and level responses from servers.
You may determine if one of these errors was returned using the successfulclientErroror serverError methods:. The throw method returns the response instance if no error occurred, allowing you to chain other operations onto the throw method:.
You may specify additional Guzzle request options using the withOptions method. Many Laravel services provide functionality to help you easily and expressively write tests, and Laravel's HTTP wrapper is no exception.
For example, to instruct the HTTP client to return empty, status code responses for every request, you may call the fake method with no arguments:. Alternatively, you may pass an array to the fake method. The array's keys should represent URL patterns that you wish to fake and their associated responses. Any requests made to URLs that have not been faked will actually be executed. Sometimes you may need to specify that a single URL should return a series of fake responses in a specific order.
You may accomplish this using the Http::sequence method to build the responses:. When all of the responses in a response sequence have been consumed, any further requests will cause the response sequence to throw an exception.
If you would like to specify a default response that should be returned when a sequence is empty, you may use the whenEmpty method:. If you would like to fake a sequence of responses but do not need to specify a specific URL pattern that should be faked, you may use the Http::fakeSequence method:.
If you require more complicated logic to determine what responses to return for certain endpoints, you may pass a callback to the fake method. When faking responses, you may occasionally wish to inspect the requests the client receives in order to make sure your application is sending the correct data or headers. You may accomplish this by calling the Http::assertSent method after calling Http::fake.
