Question

我正在尝试在Android模拟器上运行python脚本。但是，我正在拒绝连接＆＃34; （URLError）在Python中。我的服务器在同一台笔记本电脑（localhost）和同一端口上运行。服务器设计用于打印终端本身发送给它的各种请求。但是，我甚至无法与Web服务器建立连接（即，它不会打印出由python脚本发送给它的Web请求）。但我可以通过在Web浏览器本身的地址栏上写入URL来访问Web服务器上的其他文件，服务器会相应地在终端上打印请求。

完整的python脚本如下：

import android
import json
import time

import urllib
import urllib2

hello_msg     = "Welcome to Coach Kelly's Timing App"
list_title    = "Here is your list of athletes:"
quit_msg      = "Quitting Coach Kelly's App."
web_server    = 'http://127.0.0.1:8080'
get_names_cgi = '/cgi-bin/generate_names.py'

def send_to_server(url, post_data=None):

    if post_data:
        page = urllib2.urlopen(url, urllib.urlencode(post_data))

    else:
        page = urllib2.urlopen(url)

    return(page.read().decode("utf8"))


app = android.Android()


def status_update(msg, how_long=2):

    app.makeToast(msg)
    time.sleep(how_long)


status_update(hello_msg)


athlete_names = sorted(json.loads(send_to_server(web_server + get_names_cgi)))

app.dialogCreateAlert(list_title)
app.dialogSetSingleChoiceItems(athlete_names)
app.dialogSetPositiveButtonText('Select')
app.dialogSetNegativeButtonText('Quit')
app.dialogShow()

resp = app.dialogGetResponse().result

status_update(quit_msg)

以下是我的追溯输出：

    athlete_names = sorted(json.loads(send_to_server(web_server + get_names_cgi)))

urllib2.URLError: <urlopen error [Errno 111] Connection refused>

我提到了有关此讨论的其他主题，但无法得到一个非常令人满意的答案。因此，在清除URLError

时会有任何帮助
