python 打印json格式的数据中文显示问题

python在做接口测试的时候，打印出来的json格式的中文数据显示异常

例如：

    def test_bookOrder(self):
        self.url="http://mobapi.senbaba.cn/bookOrder"
        self.data={"confirm":"0","withTolls":"false","destinationPlace":"深圳北站","tdays":"0","destinationCoords":"{'area':',深圳市,宝安区,','coords':[22.616128,114.037994],'name':'深圳北站'}","departureCoords":"{'area':',广州市,越秀区,','coords':[23.155001,113.264057],'name':'广州火车站'}","departurePlace":"广州火车站","etBeginTime":"2016-07-13 15:52:00","pathway":"[]","vehicleTypeCode":"VT0001","jobType":"0","remark":"test","couponCode":"","count":"1","pathway":"[]","addItion":"false","components":"","contractPhone":"15112408147","tripNo":"test","tolls":"0","contractName":"test","cost":"620","etFinishTime":"2016-08-30 19:23:18"}
        z=requests.post(self.url,self.data)
        print(z.json())

打印出来的消息显示的是：{u'status': u'failed', u'error': {u'msg': u'\u8bf7\u767b\u9646\u540e\u8fdb\u884c\u64cd\u4f5c!', u'code': u'err_needlogin'}}

发现全是中文uncode显示

解决方法：

    def test_bookOrder(self):
        self.url="http://mobapi.senbaba.cn/bookOrder"
        self.data={"confirm":"0","withTolls":"false","destinationPlace":"深圳北站","tdays":"0","destinationCoords":"{'area':',深圳市,宝安区,','coords':[22.616128,114.037994],'name':'深圳北站'}","departureCoords":"{'area':',广州市,越秀区,','coords':[23.155001,113.264057],'name':'广州火车站'}","departurePlace":"广州火车站","etBeginTime":"2016-07-13 15:52:00","pathway":"[]","vehicleTypeCode":"VT0001","jobType":"0","remark":"test","couponCode":"","count":"1","pathway":"[]","addItion":"false","components":"","contractPhone":"15112408147","tripNo":"test","tolls":"0","contractName":"test","cost":"620","etFinishTime":"2016-08-30 19:23:18"}
        z=requests.post(self.url,self.data)
        change=z.json()
        new=json.dumps(change, ensure_ascii=False)
        print(new)

打印出来的消息显示为：{"status": "failed", "error": {"msg": "请登陆后进行操作!", "code": "err_needlogin"}}

通过json库里面的dumps方法可以让其显示为中文，默认是以ASCII来解析code，中文不在ASCII编码当中，所以无法正常显示。json.dumps方法讲ASCII编码设置为false即可解决此问题。
