blocks|key|4479815|text|首先你的问题是关于输入类的拼写，应该是输入而不是输入。并且您必须导入具有良好名称空间的类。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4479816|use+Illuminate\Support\Facades\Input;|code-block|syntax|javascript|4479817|如果你想把它叫做'input‘而不是'Input'，添加这个：|4479818|use+Illuminate\Support\Facades\Input+as+input;|4479819|其次，通过route.php将数据存储到数据库中是一种很糟糕的方式，而且您不会处理数据验证。如果发送的参数不是您期望的，可能会出现SQL错误，这是由数据类型引起的。您应该使用控制器来与信息交互，并在控制器方法中通过模型进行存储。|4479820|route.php文件处理路由。它的设计目的是在控制器和所请求的路由之间建立链接。|4479821|要了解控制器、中间件、模型、服务...+http://laravel.com/docs/5.1/|offset|length|4479822|如果您需要更多关于问题的信息和解决方案，可以加入社区：https://laracasts.com/|4479823|致以问候。|4479824|entityMap|0|LINK|mutability|MUTABLE|url|http://laravel.com/docs/5.1/|1|https://laracasts.com/^0|0|0|0|0|0|0|K|S|0|0|R|M|1|0|0^^$0|@$1|2|3|4|5|6|7|16|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|17|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|18|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|19|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|1A|8|@]|9|@]|A|$]]|$1|M|3|N|5|6|7|1B|8|@]|9|@]|A|$]]|$1|O|3|P|5|6|7|1C|8|@]|9|@$Q|1D|R|1E|1|1F]]|A|$]]|$1|S|3|T|5|6|7|1G|8|@]|9|@$Q|1H|R|1I|1|1J]]|A|$]]|$1|U|3|V|5|6|7|1K|8|@]|9|@]|A|$]]|$1|W|3|-4|5|6|7|1L|8|@]|9|@]|A|$]]]|X|$Y|$5|Z|10|11|A|$12|13]]|14|$5|Z|10|11|A|$12|15]]]]

In first your problem is about the spelling of the input class, should be Input instead of input. And you have to import the class with the good namespace. 

<pre><code>use Illuminate\Support\Facades\Input;
</code></pre>

If you want it called 'input' not 'Input', add this :

<pre><code>use Illuminate\Support\Facades\Input as input;
</code></pre>

Second, It's a dirty way to store into the database via route.php,
and you're not processing data validation.
If a sent parameter isn't what you expected, maybe an SQL error will appear, its caused by the data type.
You should use controller to interact with information and store via the model in the controller method.

The route.php file handles routing.
It is designed to make the link between the controller and the asked route.
