Larval 使用问题
- 数据配置
在 app/config/database.php 文件修改数据库配置后，还不能生效，必须要修改 .env 文件才能生效；
php artisan 命令执行报错： Illuminate\Foundation\ComposerScripts::postInstall
$ php artisan optimize
PHP Parse error: syntax error, unexpected 'class' (T_CLASS), expecting identifier (T_STRING) or variable (T_VARIABLE) or '{' or '$' in /data/d2/wwwroot/baking-server/artisan on line 31
Script php artisan optimize handling the post-install-cmd event returned with error code 255
解决：直接执行 php artisan optimize 即可解决
- notfoundhttpexception in routecollection.php line 161 laravel 5
Larval return error code 500
Resolve way: sudo chmod -R 777 ./storage
ErrorException in Filesystem.php line 111: file_put_contents(/data/d2/wwwroot/baking-server/bootstrap/cache/services.php): failed to open stream: Permission denied
Issue: Always not found httpexception in route collection.php line 161 larval 5
将 /project_name/app/Http/Controllers/user 目录，修改为 /project_name/app/Http/Controllers/User。
打开 URL: http://example.com/lamp/lam/user/login ，就会出现提示 UserController.php 中没有 login method。
解决方案：执行 php composer.phar dump-autoload -o
/data/d2/wwwroot/baking-server
nginx.conf
# baking project
location /baking/bak {
index wc.php;
if (!-e $request_filename){
rewrite ^/baking/(.*)$ /baking-server/index.php?s=$1 last;
}
###access_log /data/d2/logs/baking.access.log main;
}
#route.php
Route::group(
['prefix'=>'bak'], function() {
Route::get('/', function() {
return view('welcome');
});
}
create table bak_socket_connect(
id int(11) auto_increment,
primary key(id),
mac varchar(200),
socket text
) engine = InnoDB default charset=utf8;
insert into bak_device values(‘1223234532’, ‘abcdef’, ‘abc’,
‘123456789’, ‘defaultdefault’, ’12’, ’09’,
‘shenzhen’, ’90’, ‘2016-08-10’,’2016-08-10’);

- 如何对某些 URIs 关闭CsrfToken校验
打开 app/Http/Middleware/VerifyToken.php 文件，在 $except 数组中添加 URI 即可，如：$except = [‘lam/*’];
- Controller 中的数据操作
// 二维数组形式，数组里面是一个个对象
$user_info = DB::table('customer')->where($where)->get();
// 只返回一个对象
$user_info = DB::*table*('customer')->where($where)->first();
print_r($user_info);
Controller 中 function 如何使用跳转
return redirect('bak/device/devices');
- View 中如何使用 URL 呢？
blade 模板
<a href="{{ url('page') }}">Some Text</a>
without blade
<a href="<?php echo url('page') ?>">Some Text</a>
