用字典进行url的参数拼接

import urllib.parse
url = ‘http://www.baidu.com/index.html‘;

data = {
    ‘name‘:‘bowen‘,
    ‘age‘:25,
    ‘sex‘:‘male‘,
}
lt = []
for k,v in data.items():
    lt.append(k+‘=‘+str(v))
# 这个是在for循环外面的，就是将列表的元素之间用&符号连接起来
query_string = ‘&‘.join(lt)

print(lt)
print(query_string)
url = url + ‘?‘+query_string
print(url)

import urllib.parse
url = ‘http://www.baidu.com/index.html‘;

data = {
    ‘name‘:‘bowen‘,
    ‘age‘:25,
    ‘sex‘:‘male‘,
}
data1 = {
    ‘name‘:‘博文‘,
    ‘age‘:25,
    ‘sex‘:‘male‘,
}
query_string = urllib.parse.urlencode(data)
print(query_string)
url1 = url + ‘?‘+query_string
print(url1)

query_string1 = urllib.parse.urlencode(data1)

url2 = url + ‘?‘+query_string1
print(url2)
