错误:

的参数1答案 0 :(得分:0)
您可能正在使用ajax请求调用此函数并将该名称放在查询字符串中。在这种情况下,name
参数不会作为函数的属性发送,但会成为请求对象的一部分。
你可以这样解决这个问题:
public function name(\Illuminate\Http\Request $request) {
$user = AdminLogin::find($request->username);
return response()->json($user);
}

You should try this :
public function name($username) {
$user = AdminLogin::where('username',$username)->first();
return response()->json(['user' => $user]);
}
OR
public function name(\Illuminate\Http\Request $request) {
$user = AdminLogin::where('username',$request->username)->first();
return response()->json(['user' => $user]);
}

您的控制器方法正在使用用户名参数,但路由绑定未通过。改变你的路线
$app->get('username', 'AdminLoginController@name');
到
$app->get('user/{username}', 'AdminLoginController@name');
如果您不想更改路线,请将控制器功能签名更改为以下内容(如其他答案所示),并确保您传递的用户名为&#39;在调用url时作为请求参数。
public function name(\Illuminate\Http\Request $request) {
$user = AdminLogin::where('username',$request->username)->first();
return response()->json(['user' => $user]);
}
