吐槽net下沒有靠譜的FastDFS的sdk之使用thrift實現JAVA和C#互通

一線碼農發表於2018-03-25

ASTJavaC#

　事情是這樣的，在一個新專案中引入了fastdfs，用這玩意做一些小資料的儲存還是很方便的，然後在nuget上就找到了一個FastDFS的sdk，如下圖：

一眼就看到了這個top1的sdk，應該會比較靠譜。。。簡單的在專案中應用了一下沒啥問題就忽悠上線了，然後就悲劇了，測試那邊反饋說上傳了一個

人群，拉下來的時候少了幾個人，我的使用方式是將一批customerid按照bitmap的形式存到byte[]陣列傳到fastdfs，最後硬著頭皮追蹤下來發現是這個所謂

的sdk在upload的時候在bytes陣列處理上出了bug，這下無語了，哎，nuget上這寫sdk的估計也就是個人寫著玩玩丟上去的，哪裡敢用到生產上，還好在測

試環境發現了，不然又得出什麼亂子了。

一：解決辦法

　　問題還得要解決，不過慶幸的是，fastdfs是阿里的一個大牛YuQing寫的，那應該有java的sdk更靠譜一點，用maven的話更方便。

        <dependency>
            <groupId>net.oschina.zcx7878</groupId>
            <artifactId>fastdfs-client-java</artifactId>
            <version>1.27.0.0</version>
        </dependency>

pull下來以後，這個sdk果然是fastdfs的作者寫的，這下子安全感暴增，測試了一下，那個bug用這個sdk果然就沒有問題了。。。開心~~~~

然後流程圖大概就變成了這個樣子。

二：解決C# 和 JAVA的互通問題

　　互通方式比較多，除了走rest這種面向http的方式，還可以使用thrift，grpc這種tcp的模式，最後我決定還是採用thrift走一遭，目前最新的版本是0.11了。

網址：http://thrift.apache.org/。看了一下C#的thrift sdk，貌似最高支援0.9.1，網址為：http://archive.apache.org/dist/thrift/0.9.1/ ，

有了這個thrift-0.9.1.exe之後，接下來就可以定義Thrift的DSL，這個DSL可以讓thrift-0.9.1.exe 生成各個語言版本的sdk。

1. 定義Thrift DSL

service ThriftService
{
    string Upload(1: binary data),
    binary Download(1: string path),
    bool Remove(1: string path)
}

有人可能會問，這個DSL怎麼寫，這個大家可以看看官方的DSL的各個關鍵詞描述的網址：http://thrift.apache.org/docs/idl 還是比較簡單的，如果不清楚的

話，這個是示例大全： https://git-wip-us.apache.org/repos/asf?p=thrift.git;a=blob_plain;f=test/ThriftTest.thrift;hb=HEAD ，然後儲存為1.thrift。

2. 通過thrift生成 C# SDK

生成的方式可以參考一下官網的模板：

thrift --gen <language> <Thrift filename>

C:\Users\hxc>cd C:\java\lib\thrift

C:\java\lib\thrift>thrift-0.9.1.exe -gen csharp C:\java\lib\thrift\1.thrift

可以看到，執行完之後，就多了一個gen-csharp資料夾，點進去看一下，會發現有一個檔名為DSL中定義的ThriftService.cs檔案。

3. 通過thrift生成 JAVA SDK

執行完下面這條語句，你會發現你的資料夾又多了一份gen-java 。

C:\java\lib\thrift>thrift-0.9.1.exe -gen java C:\java\lib\thrift\1.thrift

三：SDK整合

　改造之後，我們使用JAVA作為服務端，C#作客戶端，服務端要做的事情就是通過JAVA來封裝FastDFS，然後讓C#來呼叫。

1. JAVA服務端

《1》使用fastDFS 和 Thrift的Maven地址：

        <!-- https://mvnrepository.com/artifact/org.apache.thrift/libthrift -->
        <dependency>
            <groupId>org.apache.thrift</groupId>

《2》 ThriftServiceImpl.java 實現類：

《3》 FastDFS的封裝類

 1 package com.datamip.thrift;
 2 
 3 import java.io.IOException;
 4 
 5 import org.csource.common.MyException;
 6 import org.csource.fastdfs.ClientGlobal;
 7 import org.csource.fastdfs.StorageClient;
 8 import org.csource.fastdfs.StorageServer;
 9 import org.csource.fastdfs.TrackerClient;
10 import org.csource.fastdfs.TrackerServer;
11 
12 import com.datamip.utils.PropertiesUtils;
13 
14 public class FastService {
15 
16     public StorageClient Create() throws IOException, MyException {
17 
18         //讀取配置檔案
19         String path = PropertiesUtils.getProperties("setting.properties","fastdfs");
20         return this.Create(path);
21     }
22 
23     public StorageClient Create(String host) throws IOException, MyException {
24 
25         ClientGlobal.initByTrackers(host);
26 
27         // 3、建立一個TrackerClient物件。
28         TrackerClient trackerClient = new TrackerClient();
29 
30         // 4、建立一個TrackerServer物件。
31         TrackerServer trackerServer = trackerClient.getConnection();
32 
33         // 5、宣告一個StorageServer物件，null。
34         StorageServer storageServer = null;
35 
36         // 6、獲得StorageClient物件。
37         StorageClient storageClient = new StorageClient(trackerServer, storageServer);
38 
39         return storageClient;
40     }
41 }

《4》最後就是AppMain，Thrift開啟19999埠。
