使用Python中的Google Maps geocoder和urllib2 [英] Using Google Maps geocoder from Python with urllib2
本文介绍了使用Python中的Google Maps geocoder和urllib2的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我试图在Python和JSON上使用Google Maps地理编码器,但一直告诉我有一个错误的请求:
add =白金汉宫,伦敦,SW1A 1AA
geocode_url =https://maps.googleapis.com/maps/api/geocode/json?address=%s&sensor=false®ion=uk %add
print geocode_url
req = urllib2.urlopen(geocode_url)
jsonResponse = json.loads(f.read())
pprint.pprint(nest)
这会导致 urllib2.HTTPError失败:HTTP错误400:错误请求
。
但如果我简单地复制并粘贴
https:// maps.googleapis.com/maps/api/geocode/json?address=Buckingham%20Palace,%20London,%20SW1A%201AA&sensor=false®ion=uk
$ p
到浏览器栏中,它工作正常。
我的请求出了什么问题?
解决方案您需要一些网址引用编码,这是可行的:
import urllib2
import pprint
import json
add =白金汉宫,伦敦SW1A 1AA
add = urllib2.quote(add)
geocode_url =http://maps.googleapis.com/maps/api/geocode/json?address=%s&sensor=false®ion=uk%add
print geocode_url
req = urllib2.urlopen (geocode_url)
jsonResponse = json.loads(req.read())
pprint.pprint(jsonResponse)
add = urllib2.quote(add)是重要的一点。如果你有非拉丁字符,建议谷歌API需要UTF-8编码。
I'm trying to use the Google Maps geocoder with Python and JSON, but keep being told I have a bad request:
add = "Buckingham Palace, London, SW1A 1AA" geocode_url = "https://maps.googleapis.com/maps/api/geocode/json?address=%s&sensor=false®ion=uk" % add print geocode_url req = urllib2.urlopen(geocode_url) jsonResponse = json.loads(f.read()) pprint.pprint(nest)
This fails with
urllib2.HTTPError: HTTP Error 400: Bad Request
.But if I simply copy and paste
https://maps.googleapis.com/maps/api/geocode/json?address=Buckingham%20Palace,%20London,%20SW1A%201AA&sensor=false®ion=uk
into a browser bar, it works fine.
What is wrong with my request?
解决方案You need some URL quoting encoding, this works:
import urllib2 import pprint import json add = "Buckingham Palace, London, SW1A 1AA" add = urllib2.quote(add) geocode_url = "http://maps.googleapis.com/maps/api/geocode/json?address=%s&sensor=false®ion=uk" % add print geocode_url req = urllib2.urlopen(geocode_url) jsonResponse = json.loads(req.read()) pprint.pprint(jsonResponse)
The line add = urllib2.quote(add) is the important point. If you have non latin characters be advised that the google API needs UTF-8 encoding.
