這段時間，一直在整理公司的內部 rpc 服務接口，面臨的一個問題就是：由於公司內部的系統由幾個不同的語言編寫的。C# ，java，node.js 等，如何實現這些內部系統之間的接口統一調用，確實是比較麻煩，本來考慮用webapi 但是感覺內部系統之間用webapi 效率不高。最終，我們還是考慮引入Thrift ,通過Thrift整合各個不同的RPC服務。下面就Thrift 如何使用，做個簡單的介紹，本人也是初次接觸。

　　介紹

　　Thrift是一款由Fackbook開發的可伸縮、跨語言的服務開發框架，該框架已經開源並且加入的Apache項目。Thrift主要功能是：通過自定義的Interface Definition Language(IDL)，可以創建基於RPC的客戶端和服務端的服務代碼。數據和服務代碼的生成是通過Thrift內置的代碼生成器來實現的。Thrift 的跨語言性體現在，它可以生成C++, Java, Python, PHP, Ruby, Erlang, Perl, Haskell, C#, Cocoa, JavaScript, Node.js, Smalltalk, OCaml , Delphi等語言的代碼，且它們之間可以進行透明的通信。

　　Thrift 使得各個不同的語言的系統之間可以進行透明高效的通信。但是，Fackbook 的一貫作風就是只管發布，不管維護。所以，Thrift 目前還存在一些為解決的問題。大家在調研的時候，應該考慮清楚。

　　本文結合網絡上的資源對從C#開發人員的角度簡單介紹Thrift的使用，並且針對不同的傳輸協議和服務類型給出相應的C#實例，同時簡單介紹Thrift異步客戶端的實現。

　　Thrift代碼生成器windows版下載地址

　　http://www.apache.org/dyn/closer.cgi?path=/thrift/0.10.0/thrift-0.10.0.exe

　　Thrift源碼下載地址

　　http://www.apache.org/dyn/closer.cgi?path=/thrift/0.10.0/thrift-0.10.0.tar.gz

　　Window 下安裝配置

　　Thrift 不需要安裝，只需下載windows版的 Thrift代碼生成器即可，下載地址如上連接

　　註意：下載下來之後，必須把文件名字thrift-0.10.0.exe 改為 thrift.exe, 否則cmd會提示：thrift 不是內部命令的錯誤。

　　創建thrift的語法規範編寫腳本文件

　　根據thrift的語法規範編寫腳本文件Hello.thrift,代碼如下:

namespace csharp HelloThrift.Interface

service HelloService{

    string HelloString(1:string para)

    i32 HelloInt(1:i32 para)

    bool HelloBoolean(1:bool para)

    void HelloVoid()

    string HelloNull()

}

　　生成Csharp 版的服務定義類

　　然後打開cmd切換到thrift代碼生成工具的存放目錄，在命令行中輸入如下命令：thrift -gen csharp Hello.thrift

　　代碼生成工具會自動在當前目錄下把定義好的接口腳本生成C#代碼，生成後的代碼目錄如下

　　HelloService定義了服務HelloService的五個方法，每個方法包含一個方法名，參數列表和返回類型。每個參數包括參數序號，參數類型以及參數名。包含了在 Hello.thrift 文件中描述的服務 HelloService 的接口定義，即HelloService.Iface 接口，以及服務調用的底層通信細節，包括客戶端的調用邏輯HelloService.Client 以及服務器端的處理邏輯HelloService.Processor，用於構建客戶端和服務器端的功能。

　　這樣，C#版的接口代碼就生成成功了。非常簡單，下一篇，會具體的介紹服務器端如何實現調用這些接口和客戶端如何調用這些接口。
