使用urllib3時，我試圖將數據從python腳本發送到位於本地服務器（localhost8080）上的Java servlet。我收到以下錯誤：在本地主機上使用請求或urllib3從python請求servlet時出錯
Traceback (most recent call last):

我的代碼是：
import urllib3 import requests
if name == "main": #quote_number = 1
http = urllib3.PoolManager()
r = http.request('GET',url='http://localhost:8080/raspberryPi/GetValue')
if r.status != 200:
raise Exception('ServerError', quote_number, r.status)
print r
回溯告訴你什麼是問題：'拒絕連接'。您的計算機的端口8080上是否正在偵聽？ – leovp
（在Ubuntu上）netstat -ntlp | grep 8080應該列出你的程序是端口正在監聽 –
