GuzzleHttp Exception RequestException
cURL error 60: SSL certificate problem: unable to get local issuer certificate (see //curl.haxx.se/libcurl/c/libcurl-errors.html)

我在数据库里面直接创建posts表的category_id和comment_id外键约束却可以 就是通过命令行不行!migrations里面创建的先后顺序是posts>categorys>comments!

群主 好 comments和categorys这两张表都有的 我再想是不是migrate创建的时候时间先后顺序有影响?

$table->unsignedInteger('comment_id')->comment('评论id');
            $table->unsignedInteger('category_id')->comment('所属分类id');
            $table->foreign('comment_id')

public function store(UserRequest $request)

{
    //开启事务
    \DB::transaction(function () use ($request) {
        $role = $request->input('roles');
        //保存用户
        $user = User::create($request->except(['_token', 'roles', 'password_confirmation']));
        //赋予角色
        $result = $user->assignRole($role);
        if ($result) {
            alert()->success('用户添加成功!');
        } else {
            alert()->error('用户添加失败!');
        }
        return redirect()->route('user.index');
    });
}

请问各位大神如何才知道,事务执行成功?我这样子做redirect无效 数据是已经保存了!
