Question

我正在为我的项目使用Couchbase。这是我第一次使用Couchbase Lite for Android。我目前收到此错误。但是我通过了JSON Api的正确网址，你可以在这里找到它

http://query.yahooapis.com/v1/public/yql?q=select+*+from+yahoo.finance.historicaldata+where+symbol+%3D+%22YHOO%22+and
+startDate+%3D+%222015-11-02%22+and+endDate+%3D+%222016-11-02%22&format=json&diagnostics=true&env=store%3A%2F
%2Fdatatables.org%2Falltableswithkeys&callback=

但是在LogCat中我找到了这个JSON URL：

http://query.yahooapis.com/v1/public/yql?q=select+*+from+yahoo.finance.historicaldata+where+symbol+%3D+%22YHOO%22+and
+startDate+%3D+%222015-11-02%22+and+endDate+%3D+%222016-11-02%22&format=json&diagnostics=true&env=store%3A%2F
%2Fdatatables.org%2Falltableswithkeys&callback=/_local/a26bc8baaf06fc3d4d08c9b916d2a8508152b2fa

这是我得到的LogCat错误。

这是我的Couchbase代码

public void storeStockHistoryData(String stock_symbol){
        try {

            manager = new Manager(new AndroidContext(mContext.getApplicationContext()), Manager.DEFAULT_OPTIONS);
            DatabaseOptions options = new DatabaseOptions();
            options.setCreate(true);
            database = manager.openDatabase(Constants.DATABASE_NAME, options);
            com.couchbase.lite.View viewItemsByDate = database.getView("quote");
            viewItemsByDate.setMap(new Mapper() {
                @Override
                public void map(Map<String, Object> document, Emitter emitter) {
                    Object createdAt = document.get("Symbol");
                    if (createdAt != null) {
                        emitter.emit(createdAt.toString(), null);
                        Log.d(LOG_TAG, "Fetched Data: " + createdAt.toString());
                    }
                }
            }, "1.0");

            startSync(stock_symbol);

        }catch (Exception e){
            e.printStackTrace();
        }
    }

    private void startSync(String stockSymbol) {

        String url = Utils.getStockDataUrl(stockSymbol);
        URL syncUrl;
        try {
            syncUrl = new URL(url);
        } catch (MalformedURLException e) {
            throw new RuntimeException(e);
        }

        Replication pullReplication = database.createPullReplication(syncUrl);
        pullReplication.setContinuous(true);

        Replication pushReplication = database.createPushReplication(syncUrl);
        pushReplication.setContinuous(true);

        pullReplication.start();
        pushReplication.start();

        pullReplication.addChangeListener(this);
        pushReplication.addChangeListener(this);

    }

请帮我弄清问题是什么，因为我的项目提交时间不足。

您似乎尝试与您的应用程序同步Yahoo REST API。但Couchbase Lite不支持针对Yahoo REST API或其他REST API的复制。 Couchbase Lite通过SyncGateway或CouchDB（包括Cloudant）提供与Couchbase Server的复制。
