$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？

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

PHP Fatal error:  Uncaught Exception: Fail to Decode response body, got a no support type! in /home/wwwroot/zepra.com/motan/src/Motan/Serialize/Motan.php:104

Motan.php 104行 type为10

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？

Serialize/Motan.php line 104
Fail to Decode response body, got a no support type!

Connection.php中有个写死的1000000。
可以在ReadMe中说明.
遇到问题从服务端超时到代理超时挨个排查。

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？
