hessian php与Java通信

公司因业务需求准备开放一些API接口让代理商使用，周末抽了些时间了解了一下这方面的技术后，决定采用caucho.com的Hessian实现（hessian使用方便又高效）

测试环境

Window XP
hessian-3.0.7.jar（这个版本要与spring的对应，不要一味的追求最新版，我因为这个，不知是好还是坏的毛病吃了N多苦头）
HessianPHP-2.0.3
Apache2.2
PHP5.3.0

刚开始跑Java服务器端和客服端的测试都很顺利，但是当使用php5.3做为客户端访问Java时出现了好几个问题

Php代码 HessianPHP-1.0.5


include_once '../dist/Hessian.php';

include_once '../dist/HessianClient.php';

Hessian :: mapRemoteType('com.hisupplier.showroom.webservice.QueryParams', 'QueryParams');

Hessian :: mapRemoteType('com.hisupplier.showroom.webservice.ListResult', 'ListResult');

Hessian :: mapRemoteType('com.hisupplier.showroom.entity.Product', 'Product');

Hessian :: mapRemoteType('com.hisupplier.commons.page.Page', 'Page');

try {

$params = new QueryParams(114);

$url = "http://guiyou.jiaming.com/webService";

$proxy = new HessianClient($url);

echo "<br>";

print_r($proxy->hello($params));

echo "<br>";

print_r($proxy->getProduct($params));

echo "<br>";

print_r($proxy->getList($params)); //要命的问题出在这里

} catch (HttpError $ex) {

...

}

Php代码 HessianPHP-2.0.5


require_once 'HessianPHP_v2.0.3/src/HessianClient.php';

require_once 'HessianPHP_v2.0.3/src/HessianOptions.php';

require_once 'HessianPHP_v2.0.3/src/HessianTypeMap.php';

$testurl = 'http://127.0.0.1/Service/hessian/userInfoService';

$handler = new HessianTypeMap();

$handler->mapType('User', 'com.ub.common.sys.entity.User');

$proxy = new HessianClient($testurl);

$user2=$proxy->getUserByUserId('01');

print_r($user2);

echo $user2->userId;

echo $user2->getUserId();

Java代码


public interface ShowroomAPI {

String hello(QueryParams params);

ListResult<Product> getList(QueryParams params);

Product getProduct(QueryParams params);

}

第1个问题

因为php5.2.x版本后自带了DateTime类，和 HessianPHP 中的发生冲突

解决：改文件DateTime.php 为 HessianDateTime.php，类DateTime
为 HessianDateTime

第2个问题

PHP Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set()
function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'UTC' for '8.0/no DST' instead in G:\\php\\HessianPHP\\dist\\Hessian.php on line 74

解决：将date() 方法都改为 date_default_timezone_set()

第3个问题

Php代码


Exception: Hessian Parser, Malformed reply: expected r Code: 2 exception 'HessianError' with message 'Hessian Parser, Malformed reply: expected r' in E:\workspace\php-test\dist\Protocol.php:339 Stack trace:

#7 [internal function]: HessianClient->__call('getList', Array)

#8 E:\workspace\php-test\tests\test.php(23): HessianClient->getList(Object(QueryParams))

#9 {main}

google, baidu了半天也没找到相关的文章，后来把apache和php分别降到2.0和5.1还是不行，最后快放弃了试了一下yahoo，哦！my god佛祖保佑阿门，让我找了一了篇文章

Chunked http responses cause a protocol parse error

Http.php is written to perform an HTTP POST using HTTP/1.1 which means that

the Hessian client must support a HTTP header of "Transfer-Encoding:

chunked".

Protocol::parseReply() is written as follows:

if($this->read(1) != 'r') {

return new HessianError('Hessian Parser, Malformed reply: expected

r',HESSIAN_PARSER_ERROR,0,$this->stream);

}

which will fail because the first line of a chunked response will contain

the chunk length. Protocol::parseReply() needs to be written to support

chunking.

At the moment the workaround I have is to set HTTP/1.0 in Http::POST.

解决：把Http.php中的1.1改为1.0

在Http.php第200行： $out = "POST $this->url HTTP/1.1\r\n";

原来是因为http/1.1中Transfer-Encoding:chunked编码的包是分段发送的，我最后一个方法$proxy->getList($params) Java服务器端返回的数据量太大了，php这里没接收完整引起的。
