我使用Influxdb尝试使用Influxdb v4.0.0在本地Influxdb上编写一些'measurements'
...
我有点困惑,因为有些地方说你使用dict或者你可以使用json和/或协议....
从这里http://influxdb-python.readthedocs.io/en/latest/examples.html#tutorials-pandas以及此处和https://github.com/influxdata/influxdb-python/blob/master/influxdb/client.py
1st - 使用以下命令创建数据库对象:
InfluxDBClient('localhost', database='DBNAME')
2nd - 使用数据创建dict:
measurement = {}
measurement['measurement'] = 'energy'
measurement['tags'] = {}
measurement['fields'] = {}
measurement['tags']['MeterID'] = str(meterId)
measurement['fields']['Energy_Wh'] = str(eFrame.getReading())
3rd - 将数据推送到BD:
try:
self.db.write(measurement)
except Exception as e:
print e
该程序有效,但数据库中没有存储数据,而是我的控制台输出如下:
2017-01-11 12:41:09,741 - INFO - Saving Meter: MeterId = 09060178
u'points'
Meter-ID: 09060178 Energy Value (Wh): 10380300
{'fields': {'Energy_Wh': '10380300'}, 'tags': {'MeterID': '09060178'}, 'measurement': 'energy'}
1line logger file info
2line error/Exception
3line value returned by device
4line generated dict
(prints except logging are executed last)
我似乎无法找到我写错的原因或内容以及u'points'
错误意味着什么......有人可以帮忙吗?

您可以尝试按以下方式执行此操作(如examples中所示):
from influxdb import InfluxDBClient
client = InfluxDBClient(host, port, user, password, dbname)
client.create_database(dbname)
json_body = [
{
"measurement": "cpu_load_short",
"tags": {
"host": "server01",
"region": "us-west"
},
"time": "2009-11-10T23:00:00Z",
"fields": {
"value": 0.64
}
}
]
client.write_points(json_body)

我建议使用Pinform库(一种用于InfluxDB的python ORM)来轻松获取时间戳,字段和标签。它使用正确的功能处理写入和读取。
