Question

我正在运行 lambda，它将过滤掉正在运行的 ec2 实例并使用 HTTP 发布请求将有效负载发送到 slack 通道，当我运行代码时，它会过滤掉输出中的正在运行的实例，但它在执行时显示 LocationParseError。如何解决这个错误？

import json
import boto3
import logging

import os
import urllib3
import urllib.parse
from urllib3.util import parse_url
from urllib3.exceptions import (
    DecodeError, ReadTimeoutError, ProtocolError, LocationParseError)


#from urlparse import parse_qs
from boto3 import resource

ec2 = boto3.resource('ec2')
region = 'us-east-1'



def lambda_handler(event, context):
 #print(json.dumps(event))
    ec2 = boto3.resource('ec2', region)
    url = "https://hooks.slack.com/services/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"
    
    filters = [
        {
            'Name': 'instance-state-name', 
            'Values': ['running']
        }
    ]

    instances = ec2.instances.filter(Filters = filters)

    RunningInstances = []

    for instance in instances:
        RunningInstances.append(instance.id)

    instanceList = json.dumps(RunningInstances)
    
 
                                       #List out running ec2 instances

  
  
 
   
    print(instanceList) 
    http = urllib3.PoolManager()
  
   
 
              
    req = http.request(url, (instanceList), {'Content-Type': 'application/json'})
        ```

使用带有 Post 请求的 lambda 将有效负载发送到 slack 时出现 LocationParseError
