我运行这段代码:

    private void notify(String date, int space) throws IOException {

        String ACCOUNT_SID = "dddddd";
        String AUTH_TOKEN = "ggggggg";
        String TWILIO_PHONE = "+my twilio project";
        String ELAD_PHONE = "+my real number";

        TwilioRestClient client;
        client = new TwilioRestClient(ACCOUNT_SID, AUTH_TOKEN);

        // Build a filter for the CallList
        Map<String, String> params = new HashMap<String, String>();
        params.put("Url", "http://demo.twilio.com/docs/voice.xml");
        params.put("To", ELAD_PHONE);
        params.put("From", TWILIO_PHONE);


        CallFactory callFactory = client.getAccount().getCallFactory();
        Call call;
        try {
            call = callFactory.create(params);
            call.getSid();
        } catch (TwilioRestException e) {
            String a = e.toString();
//            log("******** Failed to call", e);
        }

当我运行这一行时:

call = callFactory.create(params);

我得到这个异常:

最佳答案

我得到的回答是:

It looks like you are trying to test from your local dev environment.

With Google App Engine, if you want to test in local dev environment, I think you need to use App Engine SDK for Java. This should work when deployed to Google App Engine. Let me know if this solves this issue!

关于com.twilio.sdk.AppEngineClientConnection.flush 处的 java.lang.reflect.InvocationTargetException(AppEngineClientConnection.java :204)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/39806227/
