删除python输出中的`u`字符

Question

我创建一个表单,当我单击提交按钮时,我将3值分配到一个javascript dict并将其发送到python脚本进行处理但是我的Web浏览器告诉我一个错误!

来自Json错误:{u'food':90,u'cargo':70,u'fuel':50} SyntaxError

controller.js

function customiseCtrl($xhr){
var self = this;

checkPoint();
this.process = function(){
    if (checkPoint()){

        var newPlayer = {"fuel":value, "food":value2, "cargo":value3 };

        $xhr('POST', '/process', newPlayer, function (code, response) {
            self.x = response;

        });
    }
};


}

/ process - > python script(我正在尝试阅读"info"的信息并将其写入Google应用引擎.

def post(self):
 user = users.get_current_user()
 player = Player();

 info = json.loads(self.request.body)
 player.fuel = info.fuel
 self.response.out.write(info)

Answer 1

在许多情况下,打印Python dict不会生成有效的JSON.你想要的json模块:

import json

# ... snip ...

self.response.out.write(json.dumps(info))
# or
json.dump(info, self.response.out)
