python,socketserver的问题，求指导

Question

server.py

 import socketserver
from socketserver import  StreamRequestHandler
from socketserver import ThreadingTCPServer

addr=('localhost',9101)
class MySocketServer(StreamRequestHandler):
    def handler(self):
        while True:
            receive_data=self.request.recv(4096)
            print("接收到的数据是：%s" % receive_data)
            self.request.send(b"this is the reply from the server")




server=ThreadingTCPServer(addr,MySocketServer)
server.serve_forever()

client.py

 import socket

addr=('localhost',9101)
client=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
client.connect(addr)
client.send(b'here is client\n')
data=client.recv(4096)
print(data)

先运行server，再运行client，结果如下，第一张是客户端，第二张是服务端：


由图看出，服务端收不到客户端的消息，客户端不知从哪里接收了空的字符串，求大神指导指导
