Zend JSON服务器未返回内容

Question

我有一个zend JSON工厂，旨在为服务分发OTP，但是我无法让服务器实际返回任何内容。

<?php

class Application_Model_FrogconnectOTP
{
/**
 * Generates, stores, and returns the OTP for thesupplied user
 * 
 * @param   string  $username
 * @return  string
 */
public function generate($username)
{

     $hash = "Lol";
     return $hash;
}

/**
 * Will clear the OTP for the user.
 * 
 * @param   string  $username
 * @return  int
 */
public function delete($username) 
{
    return 1;
}
/**
 * Takes the supplied username and hash and will calculate new sums and verify the supplied hash.
 * 
 * @param   string  $username
 * @param   string  $hash
 * @return  int
 * 
 */
public function validate($username, $hash) {
    return 1;
}
}
?>

这个类是由缺省的(Ish) zend json服务器加载的，如下所示：

<?php
$this->_helper->layout->disableLayout();

$server = new Zend_Json_Server();
$OTPEngine = new Application_Model_FrogconnectOTP();
$server->setClass($OTPEngine);

if ('GET' == $_SERVER['REQUEST_METHOD']) {
    // Indicate the URL endpoint, and the JSON-RPC version used:
    $server->setTarget('/frogconnect')
           ->setEnvelope(Zend_Json_Server_Smd::ENV_JSONRPC_2);

    // Grab the SMD
    $smd = $server->getServiceMap();

    // Return the SMD to the client
    header('Content-Type: application/json');
    echo $smd;
    return;
}
$server->handle();

但是，如果我尝试使用如下所示的json字符串发出请求，服务器将以204No Content标头作为响应，但我没有收到任何内容(我应该是"Lol“

{"method":"generate","params":{"username":"johndoe"}}

任何帮助都将不胜感激

如果其他人有这个问题，这里的问题看起来是您试图强制web服务通过Zend MVC布局(我是根据处理代码顶部的disable布局推断的)。

建议您在公用文件夹中为JSON-RPC服务器创建自定义索引文件。

尝试创建文件，如下所示：

/public/api/v1.0/jsonrpc.php

<?php
// Define path to application directory
defined('APPLICATION_PATH')
|| define('APPLICATION_PATH', realpath(dirname(__FILE__) . '/../../../application'));

// Define application environment
defined('APPLICATION_ENV')
|| define('APPLICATION_ENV', (getenv('APPLICATION_ENV') ? getenv('APPLICATION_ENV') : 'production'));

// Ensure library/ is on include_path
set_include_path(implode(PATH_SEPARATOR, array(
    realpath(APPLICATION_PATH . '/../library'),
    get_include_path(),
)));

/** Zend_Application */
require_once 'Zend/Application.php';

// Create application, bootstrap, and run
$application = new Zend_Application(
    APPLICATION_ENV,
    APPLICATION_PATH . '/configs/application.ini'
);

$application->bootstrap();

// Instantiate server, etc.
$server = new Zend_Json_Server();
$server->setClass('Application_Model_FrogconnectOTP');

if ('GET' == $_SERVER['REQUEST_METHOD']) {
    // Indicate the URL endpoint, and the JSON-RPC version used:
    $server->setTarget('/api/v1.0/jsonrpc.php')
       ->setEnvelope(Zend_Json_Server_Smd::ENV_JSONRPC_2);

    // Grab the SMD
    $smd = $server->getServiceMap();

    // Return the SMD to the client
    header('Content-Type: application/json');
    echo $smd;
    return;
}

$server->handle();
?>

这将替换zend用于MVC内容的普通索引文件"/public/index.php“。
