打印 laravel 模型查询产品的 SQL

1.在路由閉包打印sql

打印一段代码生产的 sql 语句,使用路由闭包做个实验

Route::get('/get-sql', function() {
    DB::enableQueryLog();
    $data = App\Models\BusinessProduct::Enable(1)->get();
    return response()->json(DB::getQueryLog());
});

在浏览器打开:http://127.0.0.1:8000/get-sql

[
    {
        "query":"select * from `fook_business_product` where `enable` = ?",
        "bindings":[
            1
        ],
        "time":13.02
    }
]

2.在controller打印sql

2.1定義路由

Route::group(['prefix' => 'admin'], function () {
    $namespacePrefix="\\App\\Http\\Controllers\\Admin\\";
    Route::get('/product',['uses' => $namespacePrefix . 'BusinessProductController@index', 'as' => 'index']);
});

2.2定時model

<?php
 
namespace App\Models;
 
use Illuminate\Database\Eloquent\Model;
 
class BusinessProduct extends Model
{
    protected $table = 'fook_business_product';
 
    /**
     * 是否有效（1、有效，0、無效  ）
     * @author jackie <2019.01.23>
     */
    public function scopeEnable($query,$enable)
    {
        return $query->where('enable',$enable);
    }
 
}

2.3定義controller

<?php
 
namespace App\Http\Controllers\Admin;
 
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\DB;
use App\Models\BusinessProduct;
 
class BusinessProductController extends Controller
{
    public function index()
    {
        DB::enableQueryLog();
            $data = BusinessProduct::Enable(1)->first();
        return response()->json(DB::getQueryLog());
 
    }
}

2.4在瀏覽器打開：http://127.0.0.1:8000/admin/product

[
    {
        "query":"select * from `fook_business_product` where `enable` = ? limit 1",
        "bindings":[
            1
        ],
        "time":12.42
    }
]
