Laravel: iwebata ụzọ ụgbọ ala laravel

Ntugharị na Laravel na-enye ndị ọrụ ohere ịgafe arịrịọ ngwa niile gaa na onye njikwa kwesịrị ekwesị. Ọtụtụ ụzọ ndị bụ isi na Laravel na-amata ma nabata ihe njirimara Uniform Asset Identifier yana mmechi, na-enye ụzọ dị mfe na nkwuwapụta nke ụzọ ụzọ.

Kedu ihe bụ ụzọ (ụzọ)?

Ụzọ a bụ ụzọ iji mepụta URL arịrịọ maka ngwa gị. URL ndị a adịghị mkpa ka ejikọta ya na faịlụ ndị dị na weebụsaịtị ma bụrụ ndị mmadụ na-agụ na enyi SEO.

Na Laravel, a na-emepụta ụzọ n'ime folda le routes. A na-emepụta ha na faịlụ ahụ web.php maka weebụsaịtị, na n'ime api.php maka API.

Ndị a route e kenyere ndị otu middleware netwọk, na-egosipụta ọnọdụ nnọkọ na nchekwa CSRF. Ụzọ ndị dị na route/api.php ha enweghị obodo ma kenye ha na otu API middleware.
The tupu echichidefiLaravel nita na-abịa na ụzọ abụọ, otu maka webụ na otu maka API. Nke a bụ ụzọ maka webụ dị na ya dị web.php:

Route::get('/', function () {
   return view('welcome');
});

Kedu ihe bụ ụzọ na Laravel?

Ụzọ Laravel niile bụ definiti na faịlụ ụzọ dị n'ime ndekọ aha routes. Ngwa njikwa ụzọ, defietinyere na faịlụ ahụ App\Providers\RouteServiceProvider, na-ahụ maka ịhazi faịlụ ndị a na-akpaghị aka. Faịlụ route/web.php defina-enye ụzọ maka interface weebụ gị.

O kwere omume definweta ụzọ maka ọrụ njikwa a dị ka ndị a:

Route::get(‘user/{id}’, ‘UserController@show’);

Route::resource: usoro Route::resource na-arụpụta ụzọ niile bụ isi achọrọ maka ngwa ma jikwaa ya site na klaasị njikwa.

Mgbe arịrịọ dabara na ụzọ akọwapụtara URI, a na-akpọku usoro a show defiEmechara na njikwa App\Http\ControllersUserController, na-agafe paramita ụzọ na usoro.

Maka akụrụngwa, ịkwesịrị ịme ihe abụọ na ngwa ahụ Laravel. Nke mbụ, ịkwesịrị ịmepụta ụzọ akụrụngwa na Laravel nke na-enye fanye, melite, lelee na hichapụ ụzọ. Nke abụọ, mepụta ihe njikwa akụrụngwa nke na-enye usoro maka ntinye, imelite, ilele na ihichapụ.

The tupu echichidefiLaravel nita na-abịa na ụzọ abụọ: otu maka webụ na otu maka API. Nke a bụ ka ụzọ webụ dị na web.php:

Route::get(‘/’, function () {

return view(‘welcome’);

});

Laravel Middleware na-eme dị ka àkwà mmiri n'etiti arịrịọ na mmeghachi omume. Ọ nwere ike ịbụ ụfọdụ ụdị akụrụngwa nzacha.

Laravel arụ ọrụ na a etiti nke nwere ọrụ nke ikwenye ma akwadoro ngwa ndị ahịa ma ọ bụ na ọ bụghị. Ọ bụrụ na akwadoro onye ahịa, wee na-ebugharị redirects gaa na ibe ụlọ ma ọ bụ ibe nbanye.

Usoro maka route

Koodu gara aga definishes a ụzọ na home page. Mgbe ọ bụla ụzọ a natara arịrịọ get kwa /, ga-alaghachi view welcome. 

Ụzọ Laravel niile bụ definiti n'ime gi routing, nke dị n'ime ndekọ aha dei routes. N'ihi ya, l'AppProvidersRouteServiceProvider nke ngwa n'ahịrị ndekọ ndị a. Faịlụ route/web.php nwere ụzọ a na-ejikwa maka interface weebụ gị.

Usoro ụzọ dị nnọọ mfe. Mepee faịlụ kwesịrị ekwesị ('web.php` o `api.php` ) wee malite akara koodu na `Route:: `, na-esote arịrịọ ịchọrọ ikenye n'ụzọ ahụ kpọmkwem wee kọwapụta ọrụ a ga-arụ na-esote arịrịọ ahụ.

Laravel na-enye usoro ndị a:

• get
• post
• put
• delete
• patch
• options

Ụzọ ndị ahụ bụ definited na Laravel n'ime klas Route na HTTP, ụzọ ịzaghachi na nso, ma ọ bụ onye njikwa.

Otu esi emepụta ụzọ na Laravel

Ka anyị hụ ka ị ga-esi mepụta ụzọ nke gị na Laravel.

Ụzọ GET bụ isi

Ugbu a, m ga-emepụta ụzọ bụ isi nke ga-ebipụta tebụl oge nke 2.

Route::get('/table', function () {
   for($i =1; $i <= 10 ; $i++){
       echo "$i * 2 = ". $i*2 ."<br>";
   }   
});

Na koodu dị n'elu, m mepụtara ụzọ arịrịọ GET maka URL ahụ /table, nke ga-ebipụta tebụl oge nke 2 na ihuenyo.

Ugbu a, ka anyị hụ otu koodu ahụ, na-akọwapụta nọmba nke anyị chọrọ tebụl ịba ụba:

Route::get('/table/{number}', function ($number) {
   for($i =1; $i <= 10 ; $i++){
       echo "$i * $number = ". $i* $number ."<br>";
   }   
});

N'ime koodu 'number' n'etiti ihe nkwado ahụ na-anọchite anya oke, ya bụ nọmba nke a ga-agbakọ tebụl ịba ụba maka ya. Mgbe ọ bụla akọwapụtara URL nke ụdị ahụ /table/n, mgbe ahụ, a ga-ebipụta tebụl nọmba n.

Enwekwara ụzọ isi jikọta atụmatụ abụọ ahụ n'otu ụzọ. Laravel na-enye atụmatụ parampat nhọrọ nke na-enye gị ohere itinye akara nhọrọ site na iji akara ajụjụ '?' mgbe oke nhọrọ na uru mbụdefinite. Ka anyị hụ ihe atụ:

Route::get('/table/{number?}', function ($number = 2) {
   for($i =1; $i <= 10 ; $i++){
       echo "$i * $number = ". $i* $number ."<br>";
   }   
});

N'ime koodu dị n'elu, anyị mepụtara oke ụzọ anyị, na-eme nọmba nhọrọ, yabụ ọ bụrụ na onye ọrụ na-aga '/table` Mgbe ahụ, ọ ga-ewepụta tebụl nke 2 na ndabaradefinite na ọ bụrụ na onye ọrụ na-aga '/table/{number}Mgbe ahụ nọmba tebụl 'number' a ga-emepụta.

Okwu oge niile dị ka ihe mgbochi maka parampat ụzọ

N'ihe atụ gara aga, anyị mepụtara ụzọ maka ịmepụta tebụl ịba ụba, ma olee otu anyị ga-esi hụ na paramita nke ụzọ ahụ bụ nọmba n'ezie, iji zere njehie mgbe ị na-emepụta tebụl ịba ụba?

Na Laravel, ị nwere ike defikpachie mmachi na oke ụzọ site na iji usoro `where` n'ụzọ ihe atụ. Ihe 'where` na-ewere aha paramita na okwu oge niile maka oke ahụ.

Ugbu a, ka anyị hụ ọmụmaatụ nke mmachi maka oke anyị{numero}`iji jide n'aka na ọ bụ naanị ọnụọgụ ka agafere na ọrụ ahụ.

Route:: get ( '/table/{numero?}' , funzione ( $numero = 2 ) {    
   for( $i = 1 ; $i < = 10 ; $i + + ) {   
       echo "$i * $numero = " . $i * $numero . "<br>" ; 
   }   
} )->where( 'numero' , '[0-9]+' ) ;

Na koodu dị n'elu, anyị na-eji okwu mgbe niile maka nọmba ụzọ. Ugbu a, ọ bụrụ na onye ọrụ na-agbalị ịga /tebulu/ọ dịghị ga-egosipụta ewepu NotFoundHttpException.

Laravel Routing nwere ọrụ njikwa

Na Laravel, ị nwere ike definweta usoro njikwa maka ụzọ. Usoro njikwa na-arụ ọrụ niile definite oge ọ bụla onye ọrụ rutere n'ụzọ ahụ.
Na koodu na-esonụ anyị na-ekenye usoro njikwa 'functionname' na ụzọ:

Route:: get ( '/home' , 'YourController@functionname' ) ;

Koodu na-amalite na `Route::` ya mere defina-akwado usoro ihe omume ahụ. N'ikpeazụ, defiMechaa ụzọ gị na onye njikwa yana usoro ahụ site na ịgbakwunye akara @ tupu aha usoro ahụ.

Nye ụzọ aha

Na Laravel, ị nwere ike definish a aha maka ụzọ gị. Aha a na-abakarị uru. Dịka ọmụmaatụ, ọ bụrụ na ịchọrọ ibugharị onye ọrụ site n'otu ebe gaa na nke ọzọ, ịgaghị eme ya definweta URL redirect zuru ezu. Ị nwere ike ịnye aha ya naanị. Ị nwere ike defijiri usoro ` ihichapụ aha ụzọname` n'ụzọ ihe atụ.

Route::get('/table/{number?}', function ($number = 2) {
   for($i =1; $i <= 10 ; $i++){
       echo "$i * $number = ". $i* $number ."<br>";
   }   
})->where('number', '[0-9]+')->name(‘table’);

Ugbu a, enwere m ike megharịa url maka ụzọ a, site na koodu a:

$url = route('table');

N'otu aka ahụ, maka ịtụgharị gaa na URL a, syntax ziri ezi ga-abụ:

return redirect()->route('table');

Route Groups

I Route Groups, otu ụzọ n'ụzọ nkịtị, bụ ihe dị mkpa na Laravel, nke na-enye gị ohere ịmekọrịta ụzọ. Otu ụzọ bara uru mgbe ịchọrọ itinye njirimara na ụzọ niile agbakọtara. Ọ bụrụ na ị na-eji otu ụzọ, ị gaghị etinye njirimara ndị ahụ n'otu n'otu na ụzọ ọ bụla; nke a na-ezere mbiputegharị. Ọ na-enye gị ohere ịkekọrịta àgwà dịka middleware o namespaces, enweghị defimechaa njirimara ndị a n'ụzọ nke ọ bụla. Enwere ike ịfefe njirimara ndị a n'usoro n'usoro dị ka nke mbụ na usoro ahụ Route::group.

Syntax nke Otu Ụzọ Ụzọ

Route::group([], callback);  

nduru [ ]: bụ n'usoro gafere n'usoro otu dị ka nke mbụ paramita.

Ọmụmaatụ nke Route Group nel webụ.php

Route::group([], function()  
{  
   Route::get('/first' , function()  
   {  
      echo "first way route" ;   
   });  
   Route::get('/second' , function()  
   {  
      echo "second way route" ;   
   });  
   Route::get('/third' , function()  
   {  
      echo "third way route" ;   
   });  
});  

N'ime koodu, defika anyị chọta usoro otu(), nke nwere paramita abụọ, ya bụ array e closure. N'ime closure, anyị nwere ike defimechaa ole route anyị chọrọ. Na koodu dị n'elu, anyị nwere defimechaa atọ route.

Ọ bụrụ na site na ihe nchọgharị anyị na-enweta URL ahụ localhost/myproject/first onye nke mbụ na-etinye aka route pịnye na ihe nchọgharị first way route.

Site na URL localhost/myproject/second emesia nke-abua bia route pịnye na ihe nchọgharị second way route.

Mgbe na URL localhost/myproject/third emesia nke-atọ bia route pịnye na ihe nchọgharị third way route.

Prefixes nke Route Groups

Prefixes nke route a na-eji ha eme ihe mgbe anyị chọrọ ịnye nhazi URL nke ọtụtụ route.

Anyị nwere ike ezipụta prefix maka ụzọ niile definites n'ime otu na-eji prefix array option in Route Groups.

Ọmụmaatụ nke web.php

Route::group(['prefix' => 'movie'], function()  
{  
   Route::get('/godfather',function()  
   {  
     echo "Godfather casting";

   });  
   Route::get('/forrestgump',function()  
   {  
     echo "Forrest Gump casting";  
   });  
});  

Koodu ahụ nwere ụzọ atọ enwere ike ịnweta site na URL ndị a:

/movie/godfather  --->   Godfather casting

/movie/pulpfiction  --->   Pulp Fiction casting

/movie/forrestgump  --->   Forrest Gump casting

Ihe etiti

Anyị nwekwara ike ikenye middleware na ụzọ niile n'ime otu. The middleware ga-abụ defiemechara tupu ịmepụta otu. Iji hụ otu esi eme nke a, gụọ akụkọ anyị Laravel middleware ka o si arụ ọrụ.

Ihe Nlereanya:

Route::middleware(['age'])->group( function()
