ZF2 JSON數據大小問題

Question

我是Zend的新手，並盡我所能利用Zend framework2，Dojo和Zend Json服務器學習和構建Web應用程序。我用dojo組件寫了一個html頁面。我的頁面首先完全下載（此時沒有json調用）。我添加了一個onBlur函數，它可以調用Json服務器進行響應，並分析加載國家filters的響應。 Dojo filterselect使用json rpc客戶端，它調用服務器並返回數據。如果我的數據（記錄在數據庫中）高達60條記錄，那麼它工作得很好。但是如果這個列表超過了60條記錄（可能是200條以上的記錄），zend服務器會拋出一個異常（作爲響應，它包含json數據+解析失敗的異常）「警告：無法修改頭信息 - 已經發送頭在「

Json server details 
    public function populatelistAction() { 
    $class = "MO\Model\MOGuest"; 
    $server = new Server(); 
    $server->setClass($class); 
    if ('GET' == $_SERVER['REQUEST_METHOD']) { 
    $server->setTarget('populatelist')->setEnvelope(Smd::ENV_JSONRPC_2); 
    $smd = $server->getServiceMap(); 
    // Set Dojo compatibility: 
    $smd->setDojoCompatible(true); 
    header('Content-Type: application/json'); 
    echo $smd; 
    return $this->getResponse(); 
    } else { 
    //$server->handle(); 
    } 
    $server->handle(); 
    return $this->getResponse(); 
} 

請指導我這個問題，因爲我無能，因爲它的工作溫度高達60 REC和失敗，更多的則是，下面是我得到的例外。這是一個錯誤或我錯過任何事。我驗證它沒有任何與道場做的直接調用服務（使用RESTClient實現Firefox的插件）也失敗。

我堅信這是一個缺陷我已經爲此創建了一個修復程序。只有Zend團隊會確認問題並予以解決。遺憾的是截至目前還沒有人看到這個問題。

更多詳細信息在下面的鏈接：如果您打算使用此修復程序，那麼你必須確保修復是正確的，因爲我不是保證修復的合適人選。對於那個conatct Zend框架團隊。由於這對我來說只是Zend初學者的修補程序，所以修補程序必須通過Zend團隊的認證或提供一些更好的解決方案。 https://github.com/zendframework/zf2/issues/3225
