关于json返回的格式的不标准疑问

正常的json返回的格式不应该是像这样:

{ "firstName": "John", "lastName": "Smith", "male": true, "age": 25, "address": { "streetAddress": "21 2nd Street", "city": "New York", "state": "NY", "postalCode": "10021" }, "phoneNumber": [ { "type": "home", "number": "212 555-1234" }, { "type": "fax", "number": "646 555-4567" } ] }

但是禅道返回的会多转义符 

就像这样 注意data部分 都多了转义符:

{"status":"success","data":"{\"title\":\"TASK#864 \\u65b0\\u624b\\u6307\\u5f15\\u6d4b\\u8bd5\\u7528\\u4f8b1 \\\/

我看了框架源码发现在 parseJSON 这个函数里是:

private function parseJSON($moduleName, $methodName) 

 { 

 unset($this->view->app); 

 unset($this->view->config); 

 unset($this->view->lang); 

 unset($this->view->header); 

 unset($this->view->position); 

 unset($this->view->moduleTree); 

 $output['status'] = is_object($this->view) ? 'success' : 'fail'; 

 $output['data'] = json_encode($this->view); 

 $output['md5'] = md5(json_encode($this->view)); 

 $this->output = json_encode($output); 

 }

是不是和两次json_encode有关?

这样导致返回的不是标准的json格式
