python2.7: UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-3: ordinal not in range(128)

原因一：

环境：python2.7

报错：UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-3: ordinal not in range(128)

方案:

data = u"汉"
data = "汉"
if isinstance(data, unicode):
    print("unicode")
    print(str(data.encode('utf-8')))
elif isinstance(data, str):
    print("str")
    print(str(data))
else:
    print(str(data))


data = u"汉"
data = "汉"
if type(data) is unicode:
    print("unicode")
    print(str(data.encode('utf-8')))
elif type(data) is str:
    print("str")
    print(str(data))
else:
    print(str(data))

 

 

原因二：

Linux-ubuntu-uwsgi 编码非utf-8

locale

vi /etc/profile

export LANG=zh_CN.UTF-8

export LANGUAGE=zh_CN.UTF-8

source /etc/profile

reboot

或者uwsgi  

env  LANG=zh_CN.UTF-8

env LANGUAGE=zh_CN.UTF-8
