经测试，不能进行更改，更改之后django压根运行不了

经测试这个异常不影响程序运行及接口数据的返回，但抛出这么多异常看的我是浑身难受，而且项目日志也没必要收集这么多无用的异常影响其他异常的定位，当然也可以忽略这个异常不收集，但强迫症患者只考虑解如何决这个问题，网上寻找解决方案，大都是一些没有营养的垃圾内容，最后自己跟进程序查看底层源码，解决流程如下：
首先，根据第一行的提示：
File "C:\Python34\lib\wsgiref\handlers.py", line 138, in run
self.finish_response()
我这里用的编辑器是pycharm，找到handlers.py文件的138行，按住ctrl点击文件中的finish_response()方法，
就找到self.finish_response()定义的位置了。根据第二条提示：
File "C:\Python34\lib\wsgiref\handlers.py", line 181, in finish_response
self.write(data)
发现是write方法出现错误，再按住ctrl点击write方法，找到定义write方法的位置，发现第一行就定义了一条报错：
assert type(data) is bytes, \
"write() argument must be a bytes instance"
对照上面的报错信息，发现可能是变量data的类型，不是bytes，所以在handlers.py181行代码self.write(data)上面加一句：
data=data.encode()
修改时会提示，选择强制修改即可

再次刷新程序，发现所有报错都没了，程序正常运行。
