问题描述
我正在使用python请求模块通过influx API在我的本地主机上查询influxdb。代码如下。
import requests
INFLUX_DATABASE_NAME = "mydb"
influx_write_url = f'http://localhost:8086/write?db={INFLUX_DATABASE_NAME}'
influx_query_url = f'http://localhost:8086/query?db={INFLUX_DATABASE_NAME}'
pid = "CTR2257"
time_range = "7d"
pid_mod = "\'"+ pid +"\'"
query_string = f'SELECT "temp1"::field,"temp2"::field,"hum1"::field,"hum2"::field,"co2"::field,"light"::field,"fan"::field FROM "stat" WHERE productID = {pid_mod} AND time > Now() - {time_range}'
payload = {'q': query_string}
r = requests.get(url=influx_query_url,params=payload)
# Printing the response content(JSON data)
print(r.content)
print语句产生以下输出。输出包含所需的数据集，但格式不是首选。
b'{"results":[{"statement_id":0,"series":[{"name":"stat","columns":["time","temp1","temp2","hum1","hum2","co2","light","fan"],"values":[["2020-11-04T22:09:26.4960419Z",32,34,65,68,9,true,true],["2020-11-04T23:31:33.8177588Z",30,90,85,5,["2020-11-04T23:31:46.5988965Z",["2020-11-04T23:31:49.9271554Z",true]]}]}]}\n'
当我使用请求模块中的.json（）方法解析此数据时
request_data = r.json()
print(request_data)
我得到下面的python字典。同样，格式是相同的，不是所希望的。
{'results': [{'statement_id': 0,'series': [{'name': 'stat','columns': ['time','temp1','temp2','hum1','hum2','co2','light','fan'],'values': [['2020-11-04T22:09:26.4960419Z',True,True],['2020-11-04T23:31:33.8177588Z',['2020-11-04T23:31:46.5988965Z',['2020-11-04T23:31:49.9271554Z',True]]}]}]}
我正在寻找的是获取长格式而不是宽格式的每个字段的点数据。例如。
temp1 = [point1,point2,point3,....pointn]
temp2 = [point1,....pointn]
hum1 = [point1,....pointn]
hum2 = [point1,....pointn]
and so own.
任何想法或帮助都将受到高度赞赏。
