python client端收不到server端构造的结构体数据

python thrift server开发中发现thrift结构体中存在中文字符的时候client端收不到，后来发现是本身数据是unicode编码，在经过./python2.7/site-packages/thrift/protocol/TBinaryProtocol.py 这个文件的121行处理字符串的地方需要改一下，对于unicode编码的地方应该强转一下utf8，因为默认走的是utf8

find -name TBinaryProtocol.py

找到/python2.7/site-packages/thrift/protocol/TBinaryProtocol.py 

def writeString(self, str):
　　if type(str) is unicode:#
　　　　str = str.encode('utf-8')#
　　self.writeI32(len(str))
　　self.trans.write(str)

之后在运行的时候client端对于中文编码问题完美解决～

对于非中文的地方不需要修改

#!/usr/bin/env python
#coding:utf-8

reload(sys)
sys.setdefaultencoding('utf-8')
