我是Django的新手，正在尝试使用Django和wsgi创建一个web应用程序来生成服务器。 但我对Django有些误解。
这是我的密码wsgi.py公司地址：

from django.shortcuts import render
import urllib
import urllib2
from urllib2 import urlopen
import json
from wsgiref.simple_server import make_server

from django.http import HttpResponse

def map(request):
    return render(request,'WebPage1.html')

def searchMap(request):       
    address =request.POST['city']       
    return render(request,'WebPage1.html',{'Address':address})

def routers():

    urlpatterns = (
        ('/map',map),
        ('/searchMap',searchMap)

    )
    return urlpatterns
def application(environ, start_response):
    print(environ['PATH_INFO'])
    path=environ['PATH_INFO']
    status = '200 OK'
    response_headers = [('Content-Type', 'text/plain')]
    urlpatterns = routers()
    func = None
    for item in urlpatterns:
        if item[0] == path:
            func = item[1]
            break
    if func:
        return func(environ)
    else:
        return ["Hello World".encode("utf-8")]

httpd = make_server('', 8080, application)

print('Serving HTTP on port 8080...')
httpd.serve_forever()

以及我的html：

<!DOCTYPE html>
<html>
  <head>
    <title>Simple Map</title>
    <meta name="viewport" content="initial-scale=1.0">
    <meta charset="utf-8">
    <style>

  #map {
    height: 100%;
  }

  html, body {
    height: 100%;
    margin: 0;
    padding: 0;
  }
   #floating-panel {
    position: absolute;
    top: 10px;
    left: 25%;
    z-index: 5;
    background-color: #fff;
    padding: 5px;
    border: 1px solid #999;
    text-align: center;
    font-family: 'Roboto','sans-serif';
    line-height: 30px;
    padding-left: 10px;
  }
    </style>
  </head>
  <body>
      <div id="map"></div>
      <div id="floating-panel">
          <form method="POST" action="/searchMap/"> 
                 {% csrf_token %} 
                 <input name="city" type="text">
                 <input type="submit" value="Geocode" onclick="myMap()">
              </form>
      </div>      
      <div>
        {{Address}}
     </div>
  </body>
</html>

当我到达http://127.0.0.1:8080/map时得到的错误消息是：

Exception happened during processing of request from ('127.0.0.1', 54038)
Traceback (most recent call last):

简单地说，我认为Django开发人员篡改/修改他们的wsgi.py公司文件夹。Django应该为你做正确设置的工作，你可以让它坐着。你知道吗

我建议你仔细阅读这里大多数社区都读过的Django example app。它将向您介绍什么是Django应用程序，以及所有东西是如何连接在一起的。你知道吗
