使用hessian php与Java通信

去年2009-07-13在百度空间写的一篇hessian的使用总结，今天把它转过来 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 JDK 1.6 Resin3.1.9 Spring2.0.8 hessian-3.0.20.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-1.0.5-RC2 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 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 ) {       ...   }   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) { ... }

 

Java代码 public   interface  ShowroomAPI {       String hello(QueryParams params);       ListResult<Product> getList(QueryParams params);       Product getProduct(QueryParams params);   }   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

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

引用 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";
