得到的json.txt中的資料為：

{"address":"美江大廈六層","Tel":"1234567","persondata":[{"birthday":"Sun Apr 21 12:10:32 GMT+00:00 2013","married":false,"age":30,"name":"李興華"},{"birthday":"Sun Apr 21 12:10:32 GMT+00:00 2013","married":true,"age":5,"name":"魔樂科技"},{"birthday":"Sun Apr 21 12:10:32
GMT+00:00 2013","married":false,"age":7,"name":"MLDN"}],"company":"北京魔樂科技軟體學院"}
