python2.7运行报警告：UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode

一、报错信息

python代码

#coding=utf-8

from flask import Flask, request
import json

app = Flask(__name__)

@app.route('/api/user1', methods=['POST'])
def get_user1():
    user = data['data'][0] == '张三'
    print("用户：",user)	
    return data
	
if __name__ == '__main__':
    app.run(debug=True,port=8999)

二、原因及解决方法

uncode编码警告：在unicode等价比较中，把两个参数同时转换为unicode编码失败。中断并认为他们不相等。

windows下的字符串str默认编码是ascii，而python编码是utf8

解决办法：
在代码中加入如下：
import sys
reload(sys)
sys.setdefaultencoding(‘utf8’)

修改后代码：

#coding=utf-8

from flask import Flask, request
import json
import sys
reload(sys)
sys.setdefaultencoding('utf8')

app = Flask(__name__)

@app.route('/api/user1', methods=['POST'])
def get_user1():
    user = data['data'][0] == '张三'
    print("用户：",user)	
    return data
	
if __name__ == '__main__':
    app.run(debug=True,port=8999)
