求助PHP-Laravel-API大佬

Samding

目的：输入数据库中存在的id就返回图1的内容，输入不存在的id就返回图2的错误信息
现在只能实现前半句，输入不存在的id并不会返回错误信息，什么都不会返回，求大佬看下为什么

查询数据库不存在， 并不会出现异常， 所以去异常那里处理本身就是不对的， 再者， 你如果写接口，就应该有规范， 你现在这种格式返回是不行的。 建议看看接口规范。 猜你应该是新手

如果你要在异常处理器中处理的话，

public function show($id)
{
    return Article::find($id);
}

这里就应该使用

public function show($id)
{
    return Article::findOrFail($id);
}

这样当不存在时才会抛出模型不存在异常，Model::find($id) 如果不存在，返回的是 null
