因为没有定义CORS原始头，所以它会抛出403错误。当您启用Spring Framework Web套接字的调试日志时，它将显示以下错误：

OriginHandshakeInterceptor - 拒绝握手请求，Origin标头值192.168.3.202：8080不允许

将setAllowedOrigins（“*”）或setAllowedOrigins（“http://192.168.3.202:8080”）添加到您的端点，它将正常工作。

if (RasterSet[i] >= 0 && Rasterset[i] =< 10)
RasterSet[i].Average(z=> z.Z);

独立客户端和Spring Web套接字服务器
