低成本修改laravel项目成saas系统

修改provider配置，根据请求域名重写配置

class AppServiceProvider extends ServiceProvider
{

     * Register any application services.
     *
     * @return void
     */
    public function register()
    {
        $host = request()->getHost();
        //命令行模式选择项目域名
        if ($this->app->runningInConsole()){
            $io = new SetUrl();
            $input = new ArgvInput;
            $output = new ConsoleOutput;
            $output_style = new OutputStyle($input,$output);
            $io->setOutput($output_style);
            $ori_host = $host;
            if (in_array($input->getFirstArgument(),array_keys(Artisan::all()))){
                $host = $io->output->ask('请输入项目域名',$ori_host);
                if (!Str::contains($host,'.') || !config($host)){
                    if ($io->confirm('不存在配置,是否使用默认['.$ori_host.']配置?','yes')) {
                        $host = $ori_host;
                    }else{
                        $io->error('请重新尝试');
                        die;
                    }
                }
            }
        }
        if (config($host)){
            $this->globalConfig($host);
        }
    }

    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {

    }

    public function globalConfig($host){
        $map = array_keys(config($host));
        foreach ($map as $item) {
            $config = config($item);
            foreach (config($host)[$item] as $k=>$v){
                $config[$k] = $v;
            }
            app('config')->set($item, $config);
        }
        app('config')->set('logging.channels.daily', [
            'driver' => 'daily',
            'path' => storage_path('logs/'.$host.'.log'),

            'days' => 14,
        ]);
    }
}

新增重写项目配置文件，自定义要增加或要重写的配置
