登录本来是用表单的，我自作聪明的使用ajax提交
public function login(Request $request)
{
$data = $request->input();
$data = Deal::trim($data);
$name = $data['name'];
$password = $data['password'];
try{
if(empty($name)){
ExceptionResult::throwException(ErrorCode::USER_NOT_EMPTY);
}
if(empty($password)){
ExceptionResult::throwException(ErrorCode::PASSWORD_NOT_EMPTY);
}
$is_remeber = boolval(isset($data['is_remember']));
if(Auth::attempt(['name'=>$name,'password'=>$password],$is_remeber)) {
return redirect('/posts');
} else {
ExceptionResult::throwException(ErrorCode::LOGIN_FAILED);
}
} catch (ExceptionResult $e){
return Redirect::back()->with('error', $e->getMessage())->withInput();
}
}
最开始我是直接返回json格式字符串，然后登录页面判断成功后直接跳转到首页
后来发现首页使用Auth::user()拿不到登录信息 查看了cookie session都没有值
想了想，如果用ajax 那么页面直接，登录成功后后台就没有设置session 后来改为使用表单就可了
