Question

我对使用Cache :: has（＆＃39; variable＆＃39;）的条件行为非常困惑。它应该打印 A 然后 B 或 C 然而它只是 A 调试时我能看到的内容。似乎有条件的if(Cache::has($chat_id)) {被忽略了。问题是什么？

if($purpose == 'chat'){
        $action = 2;//chat 
        error_log('A');
        if(Cache::has($chat_id)) {
            error_log('B');
        } else {
            error_log('C');
            $chat = Chat::select('user_id', 'employer_id')->where('_id',$chat_id)->first();
            $user = User::select('email')->where('_id', $chat->user_id)->first();
            $employer = User::select('contact_name')->where('_id', $chat->employer_id)->first();
            $template=EmailTemplate::find('5a7af73cd40aaf098d6f7dc1');
            $find=array('@name@','@employer_name@');           
            $values=array($user->email, $employer->contact_name);        
            $body=str_replace($find,$values,$template->content);
            sendMail($user->email,$body,$template,'Tienes un mensaje de chat nuevo');
            // 1440 minutes = 1 day.
            //Cache::add($chat_id, true, 1440);
        }   
    }
    elseif($purpose == 'interview_cancelled'){
        $action = 3; //interview_cancelled
    }
    elseif($purpose == 'interview'){
        $action = 4; //interview proposed
    }

在文件顶部添加public class IPHistoryListPreference extends ListPreference { SharedPreferences sharedPref; public IPHistoryListPreference(Context context, AttributeSet attrs) { super(context, attrs); sharedPref = PreferenceManager.getDefaultSharedPreferences(context); } public IPHistoryListPreference(Context context) { super(context); sharedPref = PreferenceManager.getDefaultSharedPreferences(context); } @Override protected View onCreateDialogView() { ListView view = new ListView(getContext()); view.setAdapter(adapter()); } private ListAdapter adapter() { return new ArrayAdapter(getContext(), android.R.layout.select_dialog_singlechoice); } private CharSequence[] entries() { //convert sharedPref stringSet to CharSequence[] ? } private CharSequence[] entryValues() { //convert sharedPref stringSet to CharSequence[] ? } }。我不知道为什么laravel没有向我显示导入错误。

Cache :: has条件没有在我的代码中运行
