使用thrift進行跨語言調用（php c# java）

1：前言

實際上本文說的是跨進程的異構語言調用，舉個簡單的例子就是利用PHP寫的代碼去調C#或是java寫的服務端。其實除了本文提供的辦法還有其他辦法，例如http+xml（json）等等都能做到。

本文的意義是介紹thrift，記錄我在調試thrift時遇到的問題和相應的解決方案，避免大家走彎路。

2：大概的流程

thrift是通過socket+序列化協議來完成跨語言調用的。類似的方案有protocolbuffer（http://code.google.com/p/protobuf/）這個效能出眾，thrift效能我回頭再做測試。

使用的流程是

A：定義自己的通訊介面，介面可以使用的資料類型有string，int32等，當然你也可以自己定義枚舉和結構體

B：使用thrift.exe產生相應的代碼

C：調用

3：c#，PHP，Java在調試thrift時遇到的問題

首先我們去下載thrift,地址是http://thrift.apache.org/

解壓縮後會看到

lib下就是執行的各種語言的代碼。

A：調試PHP注意事項

一定要註冊各個php代碼也就是這句。

require_once __DIR__.'/lib/Thrift/ClassLoader/ThriftClassLoader.php';$loader = new ThriftClassLoader();$loader->registerNamespace('Thrift', __DIR__ . '/lib');$loader->register();

B：調試java注意事項

下載沒有提供的包

3：demo

定義介面（方法名不能一樣）

View Code

enum ParameterValueType{  AnsiString = 1,  Byte,  Boolean,  Currency = 4,  Date,  DateTime,  Decimal,  Double,  Guid,  Int16,  Int32,  Int64,  String,  Time,  Xml}enum ParameterValueDirection {   Input,   Output,   InputOutput,   ReturnValue}enum AdoCommandType {   Text,   StoredProcedure}struct DBParameter {  1: string DbParameterName,  2: ParameterValueType DbType,  3: string DbParameterValue,  4: ParameterValueDirection DbDirection,  5: i32 Size}struct ResultMessage {  1: i32 IsSuccess,  2: string ErrorMessage,  3: string ReturnValue,  4: list<DBParameter> ReturnParameter,  5: list<string> DataSetColumnName,  6: list<list<string>> DataSetRowValue}service DataAccessComponent {  ResultMessage ExecuteDataset(1:string ConnectionConfigKey,2:AdoCommandType commandType,3:string commandText,4:list<DBParameter> DBParameter),   ResultMessage ExecuteNonQuery(1:string ConnectionConfigKey,2:AdoCommandType commandType,3:string commandText,4:list<DBParameter> DBParameter),  ResultMessage ExecuteScalar(1:string ConnectionConfigKey,2:AdoCommandType commandType,3:string commandText,4:list<DBParameter> DBParameter),}

產生代碼

View Code

thrift -gen java ado.thriftthrift -gen php ado.thriftthrift -gen csharp ado.thrift

根據語言把產生的語言放到相應的檔案夾下。

下面簡單列一下調用代碼

1：PHP//設定IP，連接埠建立串連$socket = new TSocket('localhost', '9090');$transport = new TBufferedTransport($socket);//選定通訊協定$protocol = new TBinaryProtocol($transport);$client = new DataAccessComponentClient($protocol); //產生的類2：c#server            int port = 9090;            DataAccess da = new DataAccess();            // Processor            DataAccessComponent.Processor pc = new DataAccessComponent.Processor(da);            // Transport            TServerSocket tServerSocket =              new TServerSocket(port);            // Protocol factory            TProtocolFactory tProtocolFactory =              new TBinaryProtocol.Factory();            TServer serverEngine;            // Simple Server            serverEngine = new TSimpleServer(pc, tServerSocket);            // ThreadPool Server            //serverEngine = new TThreadPoolServer(pc,tServerSocket);            // Run it            serverEngine.Serve();client            TTransport transport = new TSocket("localhost", 9090);            TProtocol protocol = new TBinaryProtocol(transport);            ThriftTest.Client client = new ThriftTest.Client(protocol);            transport.Open();            int val = client.test("1213");            client.work();            transport.Close();            Console.WriteLine(val);            Console.ReadLine();3：javaservertry {//private static final Logger LOGGER = LoggerFactory.getLogger(Processor.class.getName());    //System.setProperty("log4j.configuration", "log4j.properties");int port = 9090;      // ProcessorThriftServer testHandler =        new ThriftServer();      ThriftTest.Processor testProcessor =        new ThriftTest.Processor(testHandler);      // Transport      TServerSocket tServerSocket =        new TServerSocket(port);      // Protocol factory      TProtocolFactory tProtocolFactory =        new TBinaryProtocol.Factory();      TServer serverEngine;      // Simple Server      //serverEngine = new TSimpleServer(new Args(tServerSocket).processor(testProcessor));      // ThreadPool Server      serverEngine = new TThreadPoolServer(new TThreadPoolServer.Args(tServerSocket).processor(testProcessor).protocolFactory(tProtocolFactory));      //Set server event handler      serverEngine.setServerEventHandler(new TestServerEventHandler());      // Run it      System.out.println("Starting the server on port " + port + "...");      serverEngine.serve();      } catch (Exception x) {x.printStackTrace();}System.out.println("done.");
