## 🚀 Quick Start
|
||||
|
||||
### 1. Create WebSocket Endpoint
|
||||
|
||||
```csharp
|
||||
var server = WireMockServer.Start();
|
||||
|
||||
server
|
||||
.Given(Request.Create().WithPath("/chat"))
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocketHandler(async ctx => {
|
||||
// Handle WebSocket connection
|
||||
}));
|
||||
```
|
||||
|
||||
### 2. Test It
|
||||
|
||||
```csharp
|
||||
using var client = new ClientWebSocket();
|
||||
await client.ConnectAsync(
|
||||
new Uri($"ws://localhost:{server.Port}/chat"),
|
||||
CancellationToken.None);
|
||||
|
||||
// Send/receive messages...
|
||||
```
|
||||
|
||||
### 3. Multiple Handler Options
|
||||
|
||||
```csharp
|
||||
// Option 1: Full context
|
||||
.WithWebSocketHandler(async ctx => { /* ctx.WebSocket, ctx.Headers, etc. */ })
|
||||
|
||||
// Option 2: Simple WebSocket
|
||||
.WithWebSocketHandler(async ws => { /* Just the WebSocket */ })
|
||||
|
||||
// Option 3: Message routing
|
||||
.WithWebSocketMessageHandler(async msg => msg.Type switch {
|
||||
"subscribe" => new WebSocketMessage { Type = "subscribed" },
|
||||
"ping" => new WebSocketMessage { Type = "pong" },
|
||||
_ => null
|
||||
})
|
||||
```

|
||||
if (context.WebSockets.IsWebSocketRequest) {
|
||||
var requestMatcher = mapping.RequestMatcher;
|
||||
if (requestMatcher.Match(requestMessage).IsPerfectMatch) {
|
||||
// Check if WebSocket is configured
|
||||
var response = mapping.Provider;
|
||||
if (response is WebSocketResponseProvider wsProvider) {
|
||||
var webSocket = await context.WebSockets.AcceptWebSocketAsync();
|
||||
await wsProvider.HandleWebSocketAsync(webSocket, requestMessage);
|
||||

## 🎓 Architecture Highlights
|
||||
|
||||
### Design Pattern: Builder Pattern
|
||||
```csharp
|
||||
Request.Create()
|
||||
.WithPath("/ws")
|
||||
.WithWebSocketSubprotocol("chat")
|
||||
.WithCustomHandshakeHeaders(("Auth", "token"))
|
||||
```
|
||||
|
||||
### Design Pattern: Provider Pattern
|
||||
```csharp
|
||||
Response.Create()
|
||||
.WithWebSocketHandler(handler)
|
||||
.WithWebSocketKeepAlive(interval)
|
||||
.WithWebSocketTimeout(duration)
|
||||
```
|
||||
|
||||
### Design Pattern: Context Pattern
|
||||
```csharp
|
||||
async (ctx) => {
|
||||
ctx.WebSocket // The connection
|
||||
ctx.RequestMessage // The request
|
||||
ctx.Headers // Custom headers
|
||||
ctx.SubProtocol // Negotiated protocol
|
||||
ctx.UserState // Custom state storage
|
||||
}
|
||||
```
