## 传输协议
|

|
||||
版本：**V2.0（2024.1.9 更新）**
|
||||
|
||||
水晶互联采用 WebSocket 进行消息传输，使用 CBOR 进行消息编码。
|
||||
水晶互联采用 WebSocket 进行消息传输，使用 Protobuf 进行消息编码。
|
||||
|
||||
为了贴近 Guava 中 `ByteArrayDataInput` / `ByteArrayDataOutput` 的使用习惯，规定以单层基本类型的数组形式使用 CBOR 。（Todo：支持更复杂的结构。）
|
||||
|
||||
参考代码：
|
||||
|
||||
```c#
|
||||
var writer = new CborWriter();
|
||||
writer.WriteStartArray(null); // 不定长数组
|
||||
// 消息序列化
|
||||
writer.WriteEndArray();
|
||||
|
||||
var reader = new CborReader(buffer);
|
||||
reader.ReadStartArray();
|
||||
// 消息反序列化
|
||||
reader.ReadEndArray();
|
||||
```
|
||||
|
||||
|
||||
|
||||
### 文档约定
|
||||
|
||||
文档中的代码块，以行首的 `>` 代表客户端向服务端传输的消息；以行首的 `<` 代表服务端向客户端传输的消息。其后的消息以纯文本形式发送。如需某一端进行操作，在尖括号后以 `!` 标志体现。
|
||||
|
||||
服务端是指水晶互联的服务端，一个 C# 程序用来完成消息转发操作。
|
||||
|
||||
客户端是指所有通过 WebSocket 连接服务端的消息提供或消费者。
|
||||
|
||||
文档中使用尖括号对 `<type:Name>` 代表必填参数，方括号对 `[type:Name]` 代表可选参数。 `type` 是参数类型，如 `string` 、 `int` 等。 `Name` 是参数名，不在具体传输过程中体现，是方便开发人员记忆的名称。
|
||||
Proto 文件见 `CrystalConnector.Protocol/proto` 目录。
|
||||
|
||||
|
||||
|
||||
### 协议约定
|
||||
|
||||
传输的所有的字符串都是 UTF-8 编码。
|
||||
|
||||
**服务端不会主动断开客户端的链接。**
|
||||
|
||||
当客户端操作成功时，服务端必定响应：
|
||||
|
||||
```
|
||||
< Successful
|
||||
```
|
||||
|
||||
当操作失败时，服务端需要指出（供机器处理的）原因：
|
||||
#### 服务端响应
|
||||
|
||||
```
|
||||
< <string:Reason>
|
||||
```protobuf
|
||||
message Result {
|
||||
oneof result {
|
||||
Successful successful = 1;
|
||||
Error error = 2;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
