打破JSON對象獲取

我有Angularjs和CodeIgnitor構建的應用程序。 angularjs設置$scope數據使用$resource service在啓動時使用ng-init獲取方法。打破JSON對象獲取

其做工精細用更少的數據，但應用程序無法與大數據計數。 GET響應中是否有任何數據大小限制，如GET參數限制？

錯誤：

Error: JSON.parse: end of data after property value in object

腳本：

app.factory('FamilyFind', ['$resource', 'Data', function ($resource, Data) { 
    return $resource(Data.rootUrl + 'admin/family_find/:id', {id: '@id'}, 
    { 
     query: { 
     isArray: true, 
     method: 'GET' 
     }, 
     update: { 
     method: 'PUT' 
     } 
    } 
); 
}]); 

// load serverside data using http resource service 

FamilyFind.get({}, function (response) { // success 

    $scope.tableData = response.data; // store result to variable 

}, function (error) { // ajax loading error 

    Data.errorMsg(); // display custom error notification 
    // error caught here 
});

我使用philsturgeon CodeIgnitor RESTful API用於後端服務。

CodeIgnitor控制器：

function family_find_get($id = '', $type = 'json') { 

    $this->response->format = $type; 
    $family    = $this->family_registration_model->find($this->get()); 

    if($family) { // success 
    $this->response(array('data' => $family), 200); 
    } else { // error 
    $this->response(array('data' => array()), 200); 
    }  
}

CodeIgnitor型號：

function find($data) { 
    $query = "SELECT dev_members.name, dev_family.house_name, dev_family.house_no, dev_family.place, 
       dev_family.post, dev_family.phone,mem.male,mem.female 
       FROM dev_family 
       JOIN dev_members ON dev_members.id = dev_family.family_head_id 
       LEFT JOIN (SELECT family_id,SUM(gender = 'Male') AS male, SUM(gender = 'Female') AS female FROM dev_members) AS mem ON mem.family_id = dev_family.id WHERE dev_family.family_reg_no != ''"; 

    if(isset($data['cluster']) && $data['cluster'] != '') { 
     $query.=" AND dev_family.cluster_id = ".$data['cluster'].""; 
    } 

    $query = $this->db->query($query); 
    return $query->result(); 
}

編輯：

當調試從服務器端的響應時，它示出了主json對象不自動關閉LY。看到從500+記錄中提取的採樣數據，

{"data":[{"name":"abc","house_name":"dfdfgdfg","house_no":"1","place":"School Road","post":"dsfdfg","phone":"1111111","male":"278","female":"264"},{"name":"dgdfg","house_name":"dgdfg","house_no":"2","place":"School Road","post":"dfgdfg","phone":"111111","male":null,"female":null},{"name":"dgdfg","house_name":"dgdfg dgd","house_no":"3","place":"School Road","post":"dfgdg","phone":"11111","male":null,"female":null},{"name":"dgg","house_name":"dgdfg","house_no":"4","place":"School Road","post":"dggd","phone":"11111","male":null,"female":null}]

誤差在JSON格式器：

Error: Parse error on line 1: 
...null,"female":null}] 
-----------------------^ 
Expecting '}', ',', got 'EOF'

當我添加數據使用RESTClient實現附加在末尾}物體接近，它工作正常。但我怎麼能在服務器端解決這個問題？爲什麼它只發生在大數據？

更新：

我已經意識到該問題是否與philsturgeon REST Controller library。相反的，

$this->response(array('data' => $family), 200);

我都試過了，

echo json_encode(array('data'=>$family));

而現在它的工作fine.Anyone知道如何在philsturgeon REST Controller library解決這個問題？

我不認爲問題出在數據大小本身。響應通常不受限制（儘管有一些可能性，因爲長時間的操作或任何其他原因，服務器關閉連接並且客戶端獲得剪切數據）。

請更好的檢查是否具有正確的數據在那裏。在我以前的經驗中，當某些數據（通常是文本數據）帶有一些特殊符號（如'，'，''，'{'，'}'等）時，我遇到了一些問題可能會損壞。它取決於您的服務器端框架如何正確處理這些符號，以便客戶端可以正確處理它。如果您可以將輸出打印到服務器端的日誌中，並檢查JSON數據的正確性。
