通过浏览器访问服务端，可以正常访问，不过运行的下面客户端的代码就抛出
java.io.IOException: Invalid Http response
at sun.net.www.protocol.http.HttpURLConnection.getInputStream0(Unknown Source)
at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source)
at socket.Client.main(Client.java:17)
//这是客户端的代码
package socket;
