Python3的urllib模块基本使用urlencode和quote

1、打开开发工具IDLE，新建‘urlencode.py’文件，并写代码如下：import urllib.requestcity = '上海'key = 'yourkey'dvar = { 'city':city, 'key':key }incode = urllib.parse.urlencode(dvar)print (incode)print (urllib.parse.quote(dvar))这里用的是某和的天气接口，key仅做演示

3、测试quote函数改写代码如下;import urllib.requestcity = '上海'key = 'yourkey'dvar = { 'city':city, 'key':key }incode = urllib.parse.urlencode(dvar)print (incode)print (urllib.parse.quote(city))

5、测试发送请求，修改代码如下;import urllib.requestcity = '上海'key = 'yourkey'dvar = { 'city':city, 'key':key }incode = urllib.parse.urlencode(dvar)url = 'http://apis.juhe.cn/simpleWeather/query?'+incodes = urllib.request.urlopen(url)print (s.read())

7、使用quote就只能自行拼接字符串请求了，注意解码响应内容，代码如下：import urllib.requestcity = '上海'key = 'yourkey&#泌驾台佐39;dvar = { 'city':city, 'key':key }incode = urllib.parse.urlencode(dvar)url = 'http://apis.juhe.cn/simpleWeather/query?'+'city='+urllib.parse.quote(city)+'&key='yourkey's = urllib.request.urlopen(url)print (s.read().decode('utf8'))
