當用戶選擇退出消息傳遞服務時，Twilio 不會在 Try/Catch 塊上引發錯誤 [PHP/Laravel]

Question

我創建了一個與我的電話號碼的對話，以選擇退出短信服務進行測試。 一旦選擇退出，我將刪除對話，因此我的應用程序不會嘗試將消息添加到當前的Conversation->sid 。

但是當我創建對話時，它不會引發 Twilio 錯誤。 即使它應該給我一個禁止的錯誤，因為收件人號碼被列入黑名單。

這是我的示例代碼：

  //store registered user in DB
    public function createConversations(Request $request)
    {
        //check if forms are inputted properly
        $this->validate($request, [
            'Friendly_Title' => 'required|unique:conversations|max:100',
            'Recipient_Number' => 'required|size:11',
            'text_body' => 'required'
        ]);

        //twilio credentials
        $sid = config('services.twilio.example_sid');
        $token = config('services.twilio.example_token');
        $twilio = new Client($sid, $token);


        //first check if guest number exists in the db('conversations')
        $convo_guest_number = DB::table('example')->where('Recipient_Number', '=', $request->Recipient_Number)->count();
        if ($convo_guest_number > 0) {
            try {
                //get requested channel_id from new conversation
                $CH_ID = DB::table('example')->where('Recipient_Number', '=', $request->Recipient_Number)->get('Channel_Id')->first();
                //update the updated_at column
                DB::table('example')->where('Recipient_Number', '=', $request->Recipient_Number)->update(['updated_at' => now()]);

                //create body message
                $message = $twilio->conversations->v1->conversations($CH_ID->Channel_Id)
                    ->messages
                    ->create([
                            "author" => "EXAMPLE AUTHOR", //$participant->sid
                            "body" => $request->text_body
                        ]
                    );
                //return back with warning message
                return back()->with('warning', 'Conversation already exists, added message to existing conversation');
            }catch (TwilioException $e) {
                return back()->with("warning", "Error: {$e->getMessage()}");
            }
        } //if new conversatoin
        else {
            try {
                //create new conversation
                $conversation = $twilio->conversations->v1->conversations
                    ->create([
                            "friendlyName" => $request->Friendly_Title
                        ]
                    );
                //store the conversation channel id
                $Conversation_SID = $conversation->sid;

                //fetch the newly created conversation
                $conversation = $twilio->conversations->v1->conversations($Conversation_SID)
                    ->fetch();

                //set recipient number and twilio number
                //add participant
                $user_number = "+". config('services.example.example_phone_number');
                $participant_number = "+" . $request->Recipient_Number;
                $participant = $twilio->conversations->v1->conversations($conversation->sid)
                    ->participants
                    ->create([
                            "messagingBindingAddress" => $participant_number,
                            "messagingBindingProxyAddress" => $user_number
                        ]
                    );

                $participant = $twilio->conversations->v1->conversations($conversation->sid)
                    ->participants
                    ->create([
                            "identity" => "EXAMPLE AUTHOR"
                        ]
                    );

                // set you as the author of the meessage
                $message = $twilio->conversations->v1->conversations($conversation->sid)
                    ->messages
                    ->create([
                            "author" => "DEMO AUTHOR", //$participant->sid
                            "body" => $request->text_body . "\r\nReply 'STOP' to unsubscribe."
                        ]
                    );

                //insert into conversations table
                DB::table('example')
                    ->insert([
                        'user_id' => auth()->user()->id,
                        'Friendly_Title' => $request->Friendly_Title,
                        'Channel_Id' => $conversation->sid,

            }catch (TwilioException $e) {
                return back()->with("warning", "Error: {$e->getMessage()}");
            }
        }
    }

我是否需要為每個小的 Twilio 任務添加一個 try/catch 塊？ 所有憑據都是 PLACHOLDERS

Twilio 開發人員布道者在這里。

由於 Conversations API 使用不同的消息發送方法（例如 SMS 或聊天）處理參與者，因此在對話中創建參與者不會檢查退出狀態。 用戶也可以在被添加到對話后選擇退出。

同樣，當您向對話發送消息時，該消息會散布給每個參與者。 因此，響應無法告訴您單個消息是否因某種原因未能發送。 API 請求將成功，因為會話中的消息資源已成功創建，即使在此過程中稍后發送單個消息失敗。

解決此問題的最佳方法是注冊交付 Webhook。 onDeliveryUpdated webhook將在消息的狀態更改時觸發，您將能夠在應用程序中記錄該消息是否已發送或因某種原因失敗。 這將允許您處理每個參與者的選擇退出和其他失敗。
