还有一种方法就是在浏览器其直接访问：
http://192.168.0.5:8086/query?db=mydata&q=select a0 from data_tt limit 10
在浏览器内会提示输入用户名称和密码，就可以显示查询到的数据
{"results":[{"statement_id":0,"series":[{"name":"data_tt","columns":["time","a0"],"values":[["1970-01-01T00:00:00Z","-0.91"],["1970-01-01T00:00:00Z","-0.91"],["1970-01-01T00:00:00Z","-0.91"],["1970-01-01T00:00:00Z","-1.24"],["1970-01-01T00:00:00Z","-1.24"],["1970-01-01T00:00:00Z","-1.25"],["1970-01-01T00:00:00Z","-1.35"],["1970-01-01T00:00:00Z","-1.35"],["1970-01-01T00:00:00Z","-1.35"],["1970-01-01T00:00:00Z","-1.38"]]}]}]}
