吐槽net下没有靠谱的FastDFS的sdk之使用thrift实现JAVA和C#互通

事情是这样的，在一个新项目中引入了fastdfs，用这玩意做一些小数据的存储还是很方便的，然后在nuget上就找到了一个FastDFS的sdk，如下图：
一眼就看到了这个top1的sdk，应该会比较靠谱。。。简单的在项目中应用了一下没啥问题就忽悠上线了，然后就悲剧了，测试那边反馈说上传了一个
人群，拉下来的时候少了几个人，我的使用方式是将一批customerid按照bitmap的形式存到byte[]数组传到fastdfs，最后硬着头皮追踪下来发现是这个所谓
的sdk在upload的时候在bytes数组处理上出了bug，这下无语了，哎，nuget上这写sdk的估计也就是个人写着玩玩丢上去的，哪里敢用到生产上，还好在测
试环境发现了，不然又得出什么乱子了。
一：解决办法
问题还得要解决，不过庆幸的是，fastdfs是阿里的一个大牛YuQing写的，那应该有java的sdk更靠谱一点，用maven的话更方便。
<dependency>
<groupId>net.oschina.zcx7878</groupId>
<artifactId>fastdfs-client-java</artifactId>
<version>1.27.0.0</version>
</dependency>
pull下来以后，这个sdk果然是fastdfs的作者写的，这下子安全感暴增，测试了一下，那个bug用这个sdk果然就没有问题了。。。开心~~~~
然后流程图大概就变成了这个样子。
二：解决C# 和 JAVA的互通问题
互通方式比较多，除了走rest这种面向http的方式，还可以使用thrift，grpc这种tcp的模式，最后我决定还是采用thrift走一遭，目前最新的版本是0.11了。
网址：http://thrift.apache.org/。 看了一下C#的thrift sdk，貌似最高支持0.9.1，网址为：http://archive.apache.org/dist/thrift/0.9.1/ ，
有了这个thrift-0.9.1.exe之后，接下来就可以定义Thrift的DSL，这个DSL可以让thrift-0.9.1.exe 生成各个语言版本的sdk。
1. 定义Thrift DSL
service ThriftService
{
string Upload(1: binary data),
binary Download(1: string path),
bool Remove(1: string path)
}
有人可能会问，这个DSL怎么写，这个大家可以看看官方的DSL的各个关键词描述的网址：http://thrift.apache.org/docs/idl 还是比较简单的，如果不清楚的
话，这个是示例大全： https://git-wip-us.apache.org/repos/asf?p=thrift.git;a=blob_plain;f=test/ThriftTest.thrift;hb=HEAD ，然后保存为1.thrift。
2. 通过thrift生成 C# SDK
生成的方式可以参考一下官网的模板：
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，执行完之后，就多了一个gen-csharp文件夹，点进去看一下，会发现有一个文件名为DSL中定义的ThriftService.cs文件。
3. 通过thrift生成 JAVA SDK
执行完下面这条语句，你会发现你的文件夹又多了一份gen-java 。
C:\java\lib\thrift>thrift-0.9.1.exe -gen java C:\java\lib\thrift\1.thrift
三：SDK集成
改造之后，我们使用JAVA作为服务端，C#作客户端，服务端要做的事情就是通过JAVA来封装FastDFS，然后让C#来调用。
1. JAVA服务端
《1》使用fastDFS 和 Thrift的Maven地址：

《2》 ThriftServiceImpl.java 实现类：

19 public static Logger logger1 = Logger.getLogger(App.class);
20
21 StorageClient client = null;
22
23 ObjectMapper objectMapper=new ObjectMapper();
24
25 public ThriftServiceImpl() throws IOException, MyException {
26 client = new FastService().Create();
27 }
28
29 //上传文件
30 public String Upload(ByteBuffer data) {

《3》 FastDFS的封装类
1 package com.datamip.thrift;
2
3 import java.io.IOException;

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 //读取配置文件
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、创建一个TrackerClient对象。
28 TrackerClient trackerClient = new TrackerClient();
29
30 // 4、创建一个TrackerServer对象。
31 TrackerServer trackerServer = trackerClient.getConnection();
32
33 // 5、声明一个StorageServer对象，null。
34 StorageServer storageServer = null;
35
36 // 6、获得StorageClient对象。
37 StorageClient storageClient = new StorageClient(trackerServer, storageServer);
38
39 return storageClient;
40 }

28
29 logger1.debug("thrift 服务端开启，开放端口 19999");
30
31 TServer server = new TSimpleServer(tArgs);
32 server.serve();
33 } catch (TTransportException e) {
34 e.printStackTrace();
35 }
36 }
