HTTP_Request2 POST參數被忽略？

Question

與捲曲的查詢，像這樣的，做工精細：

curl -XPOST -H "Content-Type: application/json" -d '{"query":"porges","start":0,"rows":10,"lang":"ENGLISH"}' http://localhost:8080/services/rest/index/z56508/search/field/search 

我我的情況，我得到11次命中那裏。但是，當我嘗試將其轉換爲HTTP_Request2時，該調用將返回數據庫中的所有匹配。

我已經看過Http_Request2 POST request not working到這裏寫代碼：

require_once 'HTTP/Request2.php'; 
    $url = "http://localhost:8080/services/rest/index/z56508/search/field/search"; 
    $data = array("query"=>"porges","start"=>"0","rows"=>"10","lang"=>"ENGLISH"); 

    $r = new HTTP_Request2($url); 
    $r->setHeader('Content-Type', 'application/json;charset=UTF-8'); 
    $r->setMethod(HTTP_Request2::METHOD_POST) 
      ->addPostParameter($data); 
    $response = $r->send(); 
    $body = $response->getBody(); 
    echo $body; 

我在做什麼錯？好像"query" => "porges"被忽略，但爲什麼？

閱讀友好手冊：http://pear.php.net/manual/en/package.http.http-request2.request.php#package.http.http-request2.request.body

addPostParameter()時，應使用要生成根據application/x-www-form-urlencoded或multipart/form-data內容類型規則POST請求體（提示：這不是JSON你要發送）。如果您有預建的申請機構，請使用setBody()：

$request->setBody('{"query":"porges","start":0,"rows":10,"lang":"ENGLISH"}');
