php - Difference between getRawBody() and getBody() methods of Zend_Http_Response? -

-

hi wondring whats difference between $response->getbody() , $response->getrawbody();

$this->_client->seturi('http://www.google.com/ig?hl=en');         try {             $response = $this->_client->request();         }catch(zend_http_exception $e)         {             echo 'zend http client failed';         }         echo get_class($response);         if($response->issuccessful())         {            $response->getbody();            $response->getrawbody();          }

getrawbody() returns body of http response is.

getbody() adjust headers i.e. decompresses content sent gzip or deflate content-encoding headers. or chunked transfer-encoding header.

the simplest way figure these questions out in @ code. great learning experience. code edited brevity. 

public function getrawbody() {     return $this->body; }  public function getbody() {     $body = '';      // decode body if transfer-encoded     switch (strtolower($this->getheader('transfer-encoding'))) {         case 'chunked':             // handle chunked body             break;         // no transfer encoding, or unknown encoding extension:         default:             // return body             break;     }      // decode content-encoding (gzip or deflate) if needed     switch (strtolower($this->getheader('content-encoding'))) {          case 'gzip':              // handle gzip encoding             break;         case 'deflate':             // handle deflate encoding             break;         default:             break;     }      return $body; }

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
