WebSocketSharp中WebSocket类

Version=1.0.2.39869
WebSocket由方法调用事件改为实例化委托调用，两种构造
1.构造函数
第一种
1 // 2 // 摘要: 3 // Initializes a new instance of the WebSocketSharp.WebSocket class with the specified 4 // WebSocket URL and subprotocols. 5 // 6 // 参数: 7 // url: 8 // A System.String that represents the WebSocket URL to connect. 9 // 10 // cancellationToken: 11 // The System.Threading.CancellationToken used to cancel websocket operations. 12 // 13 // fragmentSize: 14 // Set the size of message packages. Smaller size equals less memory overhead when 15 // sending streams. 16 // 17 // onOpen: 18 // Delegate to be invoked when the WebSocket connection has been established. 19 // 20 // onClose: 21 // Delegate to be invoked when the WebSocket connection has been closed. 22 // 23 // one rror: 24 // Delegate to be invoked when the WebSocketSharp.WebSocket gets an error. 25 // 26 // protocols: 27 // An array of System.String that contains the WebSocket subprotocols if any. Each 28 // value of protocols must be a token defined in http://tools.ietf.org/html/rfc2616#section-2.2. 29 // 30 // onMessage: 31 // Delegate to be invoked when the WebSocketSharp.WebSocket receives a message. 32 // 33 // 异常: 34 // T:System.ArgumentException: 35 // url is invalid. 36 // -or- 37 // protocols is invalid. 38 // 39 // T:System.ArgumentNullException: 40 // url is null. 41 public WebSocket(string url, CancellationToken cancellationToken = default(CancellationToken), int fragmentSize = 102392, Func<Task> onOpen = null, Func<CloseEventArgs, Task> onClose = null, Func<MessageEventArgs, Task> onMessage = null, Func<ErrorEventArgs, Task> one rror = null, params string[] protocols);View Code
参数说明：
url：要连接websocket url连接字符串
cancellationToken：用于取消websocket操作，线程
fragmentSize：消息包大小
onOpen：建立连接时调用的委托
onClose：连接关闭时调用的位图
onError：委托在WebSocketSharp时调用。WebSocket得到一个错误。
protocols：协议，每一个协议的值必须是在http://tools.ietf.org/html/rfc2616#section-2.2中定义的令牌
onMessage：WebSocket接收到一条消息
异常：
System.ArgumentException：URL无效或协议无效
System.ArgumentNullException：URL为空
第二种
1 // 2 // 摘要: 3 // Initializes a new instance of the WebSocketSharp.WebSocket class with the specified 4 // WebSocket URL and subprotocols. 5 // 6 // 参数: 7 // url: 8 // A System.String that represents the WebSocket URL to connect. 9 // 10 // sslAuthConfiguration: 11 // A ClientSslAuthConfiguration for securing the connection. 12 // 13 // cancellationToken: 14 // The System.Threading.CancellationToken used to cancel websocket operations. 15 // 16 // fragmentSize: 17 // 18 // onOpen: 19 // Delegate to be invoked when the WebSocket connection has been established. 20 // 21 // onClose: 22 // Delegate to be invoked when the WebSocket connection has been closed. 23 // 24 // one rror: 25 // Delegate to be invoked when the WebSocketSharp.WebSocket gets an error. 26 // 27 // protocols: 28 // An array of System.String that contains the WebSocket subprotocols if any. Each 29 // value of protocols must be a token defined in http://tools.ietf.org/html/rfc2616#section-2.2. 30 // 31 // 异常: 32 // T:System.ArgumentException: 33 // url is invalid. 34 // -or- 35 // protocols is invalid. 36 // 37 // T:System.ArgumentNullException: 38 // url is null. 39 public WebSocket(string url, ClientSslConfiguration sslAuthConfiguration, CancellationToken cancellationToken = default(CancellationToken), int fragmentSize = 102392, Func<Task> onOpen = null, Func<CloseEventArgs, Task> onClose = null, Func<MessageEventArgs, Task> onMessage = null, Func<ErrorEventArgs, Task> one rror = null, params string[] protocols);View Code
和第一种唯一区别多了一个身份验证sslAuthConfiguration
2.属性
Cookies：获取websocket中http cookie
Extensions：获取websocket扩展
IsSecure：获取是否安全连接
Origin：获取或设置http标头
Protocol：获取子协议
ReadyState：获取联系状态，分别是Connecting、Open、Closing和Closed四个状态
WaitTime：获取设置ping和关闭响应时间，毫秒
3.方法
Close()、Close(CloseStatusCode code)、Close(CloseStatusCode code, string reason);：分为直接关闭、状态码关闭、状态码+关闭原因三种方式
bool Connect()：建立连接
Dispose()：关闭连接，条件是状态码是Away
Uri GetUrl()：获取URL
bool IsAlive()：是否活动状态
bool Ping()、bool Ping(string message)：发送ping、发送指定ping消息
boo Send()：发送数据分为二进制、数据流、字符串以及数据流+长度四种参数
SetCookie(Cookie cookie)：设置cookie
SetCredentials(string username, string password, bool preAuth)：设置HTTP身份验证用户名、密码和认证
SetProxy(string url, string username, string password)：设置HTTP代理
