问题描述
<?PHP
namespace Database\Factories;
use App\Models\Debtor;
use Illuminate\Database\Eloquent\Factories\Factory;
class DebtorFactory extends Factory
{
/**
* The name of the factory's corresponding model.
*
* @var string
*/
protected $model = Debtor::class;
/**
* Define the model's default state.
*
* @return array
*/
public function deFinition()
{
return [
'created_at' => Now(),'created_by_id' => '3','rechtsform' => 'Unternehmen','name' => $this->faker->company
];
}
}
你可以看到如果我运行这个脚本,它会打印出以下输出:
#!/bin/bash
function demo() {
echo "This is A"
exit 1
echo "This is B"
}
input=$(demo)
echo "${input}"
echo "This is C"
由于我有 This is A
This is C
函数,脚本没有终止并打印最后一条语句 exit 1
This is C
然后程序终止了,并没有打印最后一条语句“This is C”。输出为:
#!/bin/bash
function demo() {
echo "This is A"
exit 1
echo "This is B"
}
demo
echo "${input}"
echo "This is C"
对此是否有解释,以及如何在有 This is A
时强制脚本终止,以及将函数分配给给定示例的变量。这意味着,在 exit 1
解决方法
赋值时可以查看退出状态,失败退出主脚本。
input=$(demo) || exit 1
