Keen python 库在 Flask Rest-Plus 应用程序中没有 add_event 属性

Question

我有一个简单的 Flask Rest-Plus 应用程序，它用作 Keen.io 实现的微服务前端。我已经为应用程序设置了一个自定义虚拟环境，并通过pip install keen 安装了热衷。我可以在那个环境中通过 python 控制台保存事件；但是，当我尝试从 Flask 端点执行相同操作时，它会引发以下错误消息：

[2017-08-03 12:31:02,784] ERROR in app: Exception on/api/analytics/track/pageview [POST]
Traceback (most recent call last):
  File "/home/garrett/env/event-api/local/lib/python2.7/site-packages/flask/app.py", line 1612, in full_dispatch_request

    keen.add_event("signups", {
AttributeError: 'module' object has no attribute 'add_event'

调用代码：

import keen

# This is your actual Project ID and Write Key
keen.project_id = "..."
keen.write_key = "..."

# Wrapper around event API
def track_event(event_name, payload):
    #keen.add_event(event_name, payload)
    keen.add_event("signups", {
      "username": "lloyd",
      "referred_by": "harry"
    })

感谢支持/想法！

无法让它工作，但使用请求和 Web api 重新创建端点非常容易：

import requests
import json

# This is your actual Project ID and Write Key
PROJECT_ID = "..."
MASTER_KEY = "..."

headers = {
    "Content-Type": "application/json",
    "Authorization": MASTER_KEY
}

# Event endpoint
KEEN_URI = "https://api.keen.io/3.0/projects/{:s}/events/".format(PROJECT_ID)

# Wrapper around event API
def track_event(event_name, payload):
    # Build URI
    URI = KEEN_URI + event_name

    # Make request
    r = requests.post(URI, headers=headers, data=json.dumps(payload))
    response = r.json()

    print(response)

我认为您的代码没有任何问题。我也在多个烧瓶项目中使用过 Keen。我想知道的是我看不到的东西。

由于“模块”对象有错误，这可能会有所帮助：AttributeError: 'module' object has no attribute

我也想知道有效载荷是否有问题。
