php - Laravel 无法访问下一页，因为试图获取非对象错误显示错误的属性

Question

我给出了一个让我有点困惑的代码。如果我转到我的 url，它会给我一个错误，trying to get property...当我使用它dd时$response它说 null。有人可以告诉我该怎么做以及为什么我总是收到此错误吗？我知道发生这个错误是因为$response变量没有和status对象吗？我对吗？但是当我 dd$response它说null。提前致谢

发生这种情况是因为您的响应中没有值，并且您正在尝试访问响应的属性，但该属性不存在。

你可以把is_null支票

把你的if-else循环放在这个 if 条件下

public function pingDomain(Request $request){

$host = $request->staging == 1 ? env('PROPNEX_IP') : env('PROPNEX_IP_PROD');
$url = $host. '/propnex/index.php/domain/Ping_domain?domain='.urlencode($request->domain).'&host_ip='.$request->ip;

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url );
curl_setopt($ch,CURLOPT_HTTPHEADER,[
    'Content-type: application/json'
]);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = json_decode(curl_exec($ch));
// dd($response);
 //ERROR IS HERE IN IF STATEMENT
if(!is_null($response)){
    if($response->status == 0){

        $host = $request->staging == 1 ? env('PROPNEX_IP') : env('PROPNEX_IP_PROD');
        $url = $host . '/propnex/index.php/pnapi/addDomain?type=own&domain='.$request->domain. '&site-id='. $request->siteid;

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url );
        curl_setopt($ch,CURLOPT_HTTPHEADER,[
            'Authentication: '.$request->agentid . ':'. $request->auth
        ]);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        $response = json_decode(curl_exec($ch));
        curl_close($ch);

        if($response->status == "ok"){
            return redirect()->route('ping-domain-success',[
                "fname" => $request->fname,

            ]);
        }


    }else{
