Laravel response and view

Laravel response and view basic response

// Directly responds to the string
Route: get ('example/test20', function (){
Return 'Hello World ';
});
// Customize HTTP response
Route: get ('example/test21', function (){
Return Response: make ('content does not exist', 404 );
});
// Response View
Route: get ('example/test22', function (){
Return Response: view ('test22 ');
});
// Add a cookie to the response
Route: get ('example/test23', function (){
Return Response: view ('test22')-> withCookie (Cookie: make ('key', 'This is value '));

Response redirection

// Response redirection
Route: get ('example/test24', function (){
Return Redirect: to ('example/test21')-> with ('username', 'xiaoming ');
});
// Redirect with data
Route: get ('example/test25', function (){
// The with method writes the data to the Session and obtains the data through the Session: get method.
Return Redirect: to ('example/test21')-> with ('username', 'xiaoming ');
});
// Redirect to named route
Return Redirect: route ('login ');
// The route entry with the specified name parameter.
Return Redirect: route ('Profile ', array ('user' => 1 ));
// Redirect to the specified controller method
Return Redirect: action ('homecontroller @ index ');
// Redirect to the specified controller method with parameters
Return Redirect: action ('usercontroller @ profile ', array ('user' => 1 ));

Response view

// Response View and pass parameters
Route: get ('example/test30', function (){
// Method 1
Return View: make ('test30', array ('name' => 'xiaoming '));
// Method 2
// Return View: make ('test30')-> with ('name', 'xiaoming2 ');
// Method 3
// Return View: make ('test30')-> withName ('xiaoming3 ');
// Method 4. note: share the same data in all views
// View: share ('name', 'Steve ');
});
// Input the subview in the view
Route: get ('example/test31', function (){
$ Data = array ('name' => 'John ');
// Place the sub-view in app/views/child/child_view.php. you can also pass variables to the sub-view.
Return View: make ('test30')-> with ($ data)-> nest ('child ', 'Child. child_view', $ data );
});

View component or view synthesizer

If you want to bind the specified data when creating a view, you can define the View component:

View: composer ('Profile ', function ($ view)
{
$ View-> with ('count', User: count ());
});

Add multiple views to the view component:

View: composer (array ('Profile ', 'dashboard'), function ($ view)
{
$ View-> with ('count', User: count ());
});

If you use a class-based view component:

View: composer ('Profile ', 'profilecomposer ');

The view component class is created as follows:

Class ProfileComposer {
Public function compose ($ view)
{
$ View-> with ('count', User: count ());
}
}

Special Response

// Create a JSON response
Return Response: json (array ('name' => 'Steve ', 'state' => 'CA '));
// Create a JSONP response
Return Response: json (array ('name' => 'Steve ', 'state' => 'CA')-> setCallback (Input :: get ('callback '));
// File download response
Return Response: download ($ pathToFile );
Return Response: download ($ pathToFile, $ name, $ headers );
Note: the Symfony HttpFoundation class library for file download management requires the file name to be ASCII encoded.

Response macro, use Response: macro to customize the Response

Response: macro ('caps', function ($ value)
{
Return Response: make (strtoupper ($ value ));
});

The macro method accepts two parameters: a macro name and a closure. When the macro name is called through the Response class, the closure will be executed:

Return Response: caps ('Foo ');

You can define the macro in the file in the app/start directory. Alternatively, you can organize your macros through a separate file and include the macro into a start file.
