服务提供方: java 服务调用方: php 两种情况: 1、服务提供方无法处理请求参数; 2、服务调用方无法解析返回结果 1: java服务方法

    public String sayHello(String name) {
        System.out.println("name: " + name);
        return "hello " + "GD" + " !";
    }

php调用

$rs = $cx->sayHello(['name'=>'']);

异常:

)

2: java服务方法

    public String sayHello() {
        return "hello GD !";
    }

php调用同1，可以调用到服务，并返回结果，但是php无法解析 异常

目前走的motan-go代理访问JAVA服务， JAVA服务后面会同步对接一个较耗时的服务(1~4秒处理时长) motan-go配置的6秒超时，如果JAVA服务耗时短则motan-php正常接收返回结果，但是如果耗时长，motan-php这边基本在2秒左右，报Error to read header_buffer异常， 这个异常是什么场景下会报 结合motan-go应该如何配置motan-php的超时时长？

Example of MClient->doMultiCall():

$app_name = 'phpt-test-MClient';
$group = "bj";
$service = "com.mycompany.motan.DemoServer";
$mcx = new \Motan\MClient($app_name);
$req1 = new \Motan\Request($service, 'Hello', "motan-php-client-req1");
$req2 = new \Motan\Request($service, 'Hello', "motan-php-client-req2");
$req3 = new \Motan\Request($service, 'Hello', "motan-php-client-req3");
$req1->setGroup($group);
$req2->setGroup($group);
$req3->setGroup($group);
$req1->setSerialization("breeze");
$req2->setSerialization("simple");
$req3->setSerialization("breeze");

$multi_res = $mcx->doMultiCall([
    $req1,
    $req2,
    $req3
]);

foreach ([
             $req1,
             $req2,
             $req3,
         ] as $k => $req) {
    $e = $multi_res->getException($req);
    if (!empty($e)) {
        var_dump("req" . ($k + 1) . " error " . $e);
    } else {
        var_dump($multi_res->getRs($req));
    }
}

Example of Client->multiCal():

$url_str = 'motan2://127.0.0.1:8001/com.mycompany.motan.DemoServer?group=bj&serialize=breeze';
$cx = new \Motan\Client();
$multi_res0=$cx->multiCall([
    new \Motan\URL($url_str),
    new \Motan\URL($url_str),
    new \Motan\URL($url_str),
],"Hello","client-multiple-call");
var_dump($multi_res0);

go agent 需要通过版本等值组成的键查找服务是否存在： version := "0.1" if request.GetAttachment(mpro.MVersion) != "" { version = request.GetAttachment(mpro.MVersion) } ck := getClusterKey(request.GetAttachment(mpro.MGroup), version, request.GetAttachment(mpro.MProxyProtocol), request.GetAttachment(mpro.MPath)) 但是，我跟踪了下，通过php的doCall调用方法时，版本号根本就没有到agent这边来，是我用法错误吗？

$request_id = $request_args = $request_header = NULL; isset($arguments[0]) && !empty($arguments[0]) && $request_args = $arguments[0]; $request = new \Motan\Request($this->_url_obj->getService(), $name, ...[$request_args]); isset($arguments[1]) && !empty($arguments[1]) && $request->addHeaders($arguments[1]); isset($arguments[2]) && !empty($arguments[2]) && $request->setRequestId($arguments[2]); $request->setGroup($this->_url_obj->getGroup()); $http_params = $this->_url_obj->getParams();

这上面的写法决定了通过_call调用某个远程方法时，只能支持一个参数吧？ ...[$request_args]，这个地方是否还要判断下？
