随机RuntimeException:仅支持密钥长度正确的AES-128-CBC和AES-256-CBC
随机RuntimeException:仅支持密钥长度正确的AES-128-CBC和AES-256-CBC
提问于 2017-01-09 23:44:08
我在Laravel 5.3 (在windows服务器上)也遇到了同样的问题。我做了所有可能的尝试:检查.env文件、配置、artisan新密钥生成、缓存:清除、配置:清除、作曲器更新，但问题仍然存在。
请注意，使用完全相同版本的apache、mysql、php编写的相同代码在Mac OS上不会产生此问题。
我发现密钥( Encrypter构造器的第一个参数)“有时”到达时是空的，当然它会失败。在大多数情况下，密钥是正确的，但随机地，密钥从EncryptionServiceProvider到达时是空的，这反过来会要求它进入应用程序配置。
因此，对我有效的唯一解决方案是在EncryptionServiceProvider中添加一个if ($key)，这样加密构造函数就不会被调用为空密钥。
当然，这不是一个“干净”的解决方案，也不能解释问题，但至少避免了查找充满错误的日志文件：
RuntimeException:仅支持AES-128-CBC和AES-256-CBC两种密码，页面显示正确。
如果这是一个Laravel错误，我不知道，但当然，如果有人能解释这一点，我会很高兴知道。
下面是我修改后的类:我只是在new Encrypter之前添加了if ($key)行
class EncryptionServiceProvider extends ServiceProvider
{
/**
* Register the service provider.
*
* @return void
*/
public function register()
{
$this->app->singleton('encrypter', function ($app) {
$config = $app->make('config')->get('app');
// If the key starts with "base64:", we will need to decode the key before handing
// it off to the encrypter. Keys may be base-64 encoded for presentation and we
// want to make sure to convert them back to the raw bytes before encrypting.
if (Str::startsWith($key = $config['key'], 'base64:')) {
$key = base64_decode(substr($key, 7));
}
if ($key)
return new Encrypter($key, $config['cipher']);
});
}
}更多详细信息和回溯日志：
当然，在我写这篇文章的时候，我检查了.env文件、配置、artisan新密钥生成、缓存:清除、配置:清除、作曲器更新。这个东西是好的，因为它工作的99%的时间，但随机我得到的错误。
下面是回溯：
