说明：项目中遇到请求的json数据字符串，打印出来没有问题，但是想加入到代码中，就需要进行转移
原数据为（用src代替）（没有写完）：
{"adjust_fee":"0.00","buyer_nick":"u5218u8349u6839116","buyer_obtain_point_fee":"0","buyer_rate":"false","cod_fee":"0.00","cod_status":"NEW_CREATED","consign_time":"2017-07-17 17:45:54","created":"2017-07-17 08:44:53","discount_fee":"0.00","modified":"2017-07-17 17:46:24","num":"1","num_iid":"548133026817","orders":{"order":{"adjust_fee":"0.00","buyer_rate":"false","discount_fee":"368.00","num":"1","num_iid":"548133026817","oid":"31837783667004511","outer_iid":"PM5462","payment":"446.00","pic_path":"https://img.alicdn.com/bao/uploaded/i2/91249182/TB2k9pOkR0lpuFjSszdXXcdxFXa_!!91249182.jpg",......
是一个标准的json格式。
如果直接用String json=src会编译错误，
转移：1.http:url，这里的转义，
原数据：https://img.alicdn.com/bao/uploaded/i2/91249182/TB2k9pOkR0lpuFjSszdXXcdxFXa_!!91249182.jpg
转义后：https:\/\/img.alicdn.com\/bao\/uploaded\/i1\/91249182\/TB2Ao5yldBopuFjSZPcXXc9EpXa_!!91249182.jpg
2.“"”->“"”
（目前就这两点容易出错）
