一.Laravel的装置与配置

1.下载Composer-Setup.exe (getcomposer.org)并装置
2.挪动到xampp/hotdocs文件夹，执行以下命令

php composer create-project --prefer-dist laravel/laravel blog

3.用PhpStorm关上能够看到如图我的项目构造

4.能够间接输出命令 php artisan serve 运行，也能够拜访apache,显示如下图示意胜利

这时Laravel就装置胜利了。
5.批改.env文件中的数据库信息

二.编写api接口

1.新建数据库建表插入数据

DROP TABLE IF EXISTS `book`;CREATE TABLE `book`  (  `id` int(11) NOT NULL AUTO_INCREMENT,  `book_name` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,  `book_sort` int(11) DEFAULT NULL,  `book_mark` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,  PRIMARY KEY (`id`) USING BTREE) ENGINE = MyISAM AUTO_INCREMENT = 5 CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;-- ------------------------------ Records of book-- ----------------------------INSERT INTO `book` VALUES (1, '水浒传', 1, '四大名著');INSERT INTO `book` VALUES (2, '西游记', 1, '孙悟空');INSERT INTO `book` VALUES (3, '红楼梦', 2, '无');INSERT INTO `book` VALUES (4, '三国演义', 2, '');

3.新建Model和Controller

php artisan make:model Models/Bookphp artisan make:controller BookController

批改Book.php

<?phpnamespace AppModelsModels;use IlluminateDatabaseEloquentFactoriesHasFactory;use IlluminateDatabaseEloquentModel;class Book extends Model{ use HasFactory; /**关联到模型的数据表 * @var string */ protected $table = 'book'; /**Laravel有默认工夫字段，不须要能够批改成 false * @var bool */ public $timestamps = false;}

4.创立简略的api
编写BookController.php

<?phpnamespace AppHttpControllers;use AppModelsModelsBook;use IlluminateHttpRequest;class BookController extends Controller{ public function getBookById($id) { // 依据id查问 $book = Book::find($id); // return response()是返回想要 json()转换成json字符串然而是unicode setEncodingOptions设置编码 return response()->json($book)->setEncodingOptions(JSON_UNESCAPED_UNICODE); }}

编写 routes/api.php

<?phpuse IlluminateHttpRequest;use IlluminateSupportFacadesRoute;/*|--------------------------------------------------------------------------| API Routes|--------------------------------------------------------------------------|| Here is where you can register API routes for your application. These| routes are loaded by the RouteServiceProvider within a group which| is assigned the "api" middleware group. Enjoy building your API!|*/Route::middleware('auth:api')->get('/user', function (Request $request) { return $request->user();});Route::any('/book/{id}',[AppHttpControllersBookController::class,'getBookById']);

5.php artisan serve或者间接拜访apache

一个简略接口的编写到此结束，这样写起来很简略，然而两头也遇到了点小问题，比方MySQL编码问题，Navcat有很大的问题，show variables like 'char%';在MySQL cmd中显示是utf-8然而在navcat中却成了latin,这个要在navcat连贯那里编辑编码为主动,这样就能够和零碎的一样了。
