基于python的Dwnload地图图像

基于python的Dwnload地图图像,python,google-maps,parsing,urllib,Python,Google Maps,Parsing,Urllib,我正在尝试使用urllib模块下载python中的地图图像。但它总是失败 我尝试将urllib.urlopen()与一些参数变量一起使用 在urllib.urlretrieve()中尝试 但是它不工作。而且,当我看到图像url的源代码时,我没有找到图像文件。以下是图片: 源代码: #-------------------------- PARSE IP ADDRESS ------------------------------- import re import urllib try

我正在尝试使用urllib模块下载python中的地图图像。但它总是失败

  • 我尝试将
    urllib.urlopen()
    与一些参数变量一起使用
  • urllib.urlretrieve()中尝试
但是它不工作。
而且,当我看到图像url的源代码时,我没有找到图像文件。以下是图片:

源代码:

#-------------------------- PARSE IP ADDRESS  -------------------------------
import re

try:
    mysite = urllib.urlopen('http://ip-api.com/line')
except urllib.HTTPError, e:
    print "Cannot retrieve URL: HTTP Error Code", e.code
except urllib.URLError, e:
   print "Cannot retrieve URL: " + e.reason[1]

list_of_params = mysite.read()
print list_of_params
ip_arr = list_of_params.splitlines()

#--------------------- HERE IS FIND MAP IMAGE --------------------------------------

#-------------------    DOWNLOAD MAP IMAGE And SAVE IT  ------------------------

为什么要解析地图URL?自己建造:

import json, urllib

query = '' # IP to get coordinates of, leave empty for current IP

geo = urllib.urlopen('http://ip-api.com/json/%s?fields=240' % query)
result = json.load(geo)
if result['zip']:
    zoom = 13
elif result['city']:
    zoom = 12
else:
    zoom = 6
map_img_url = "https://maps.googleapis.com/maps/api/staticmap?center=%s,%s&zoom=%i&size=320x385&sensor=false" % (result['lat'], result['lon'], zoom)
get_map_img = urllib.urlretrieve(map_img_url, "staticmap.png")
