使用socket中的struck来实现客户端发送
服务端：
客户端：

while True:

print(type(filepath))
print(len(filepath.encode("utf-8")))
if os.path.isfile(filepath):
#fileinfo_size = struct.calcsize('20sl') # 定义打包规则
# 定义文件头信息，包含文件名和文件大小
fhead = struct.pack('12sl', filepath.encode("utf-8"), os.stat(filepath).st_size)
print(os.stat(filepath).st_size)
s.send(fhead)
print (u'文件路径: ', filepath)
# with open(filepath,'rb') as fo: 这样发送文件有问题，发送完成后还会发一些东西过去
fo = open(filepath, 'rb')
while True:
filedata = fo.read(1024)
if not filedata:
break
