Question

好的，我正在尝试为烧瓶设置influxdb。
由于已经有library可以做到这一点，所以我尝试了一下。
我遍历了README引用的示例目录，所以最终得到的是：

from flask_influxdb import InfluxDB
from flask import Flask, render_template

app = Flask(__name__)
app.config['SECRET_KEY'] = 'applesandpears'
influx_db = InfluxDB(app=app)


@app.route('/newdb/<dbname>')
def newdb(dbname):
    dbcon = influx_db.connection
    dbcon.create_database(dbname)
    return ''


@app.route('/write/<dbname>')
def write(dbname):
    data_measurement = 'testseries'
    data_tags = ['time', 'value_1', 'value_2', 'value_3']

    dbcon = influx_db.connection
    dbcon.switch_database(database=dbname)
    dbcon.write_points([
        {
            "fields": {
                'value_1': 0.5,
                'value_2': 1,
                'value_3': 1.8858
            },
            "tags": {
                'tag_1': 'tag_string',
                'tag_2': 'tag_string'
            },
            "measurement": "testseries"
        }
    ])
    tabledata = dbcon.query('SELECT {0} from {1}'.format(', '.join(data_tags), data_measurement))

    data_points = []
    for measurement, tags in tabledata.keys():
        for p in tabledata.get_points(measurement=measurement, tags=tags):
            data_points.append(p)

    return render_template('table.html',
                           measurement=data_measurement,
                           columns=data_tags,
                           points=data_points)


if __name__ == '__main__':
    app.run(debug=True)

当我尝试以下查询http://localhost:5000/newdb/testdb时，出现以下错误：

requests.exceptions.ConnectionError: HTTPConnectionPool(host='localhost', port=8086): Max retries exceeded with url: /query?q=CREATE+DATABASE+%22testdb%22 (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x0000013DF2AB7E10>: Failed to establish a new connection: [WinError 10061] No connection could be made because the target machine actively refused it',))

可以找到here

来创建数据库的包装器代码。

现在，我知道这不是特定于influx-db的错误，而是Windows错误。我浏览了其他文章，并尝试禁用防火墙，但这似乎不起作用。我也尝试过以管理员身份运行cmd，但是再次没有任何反应。

问题出在哪里？

这可能是由于代理。您需要在以下位置指定代理设置您的代码或项目的入口点。

import os #for proxy

proxy = 'http://10.XX.XX.XX:8X8X' #your own proxy 'http://<user>:<pass>@<proxy>:<port>'

os.environ['http_proxy'] = proxy 
os.environ['HTTP_PROXY'] = proxy
os.environ['https_proxy'] = proxy
os.environ['HTTPS_PROXY'] = proxy
#rest of code .....

WinError 10061：无法建立连接，因为目标计算机主动拒绝了该连接[带Flask的InfluxDB]
