Python接口测试-以&连接拼接字典数据（get中url请求数据）

get请求的utl数据是这样的，例如：/banner/findBanner?bannerType=1&_=1556107073181

'''
1-banner图-banner/findBanner
'''
str1=parse.urlencode(data1)
url1='{0}/banner/findBanner?bannerType=1&_=1556107073181'.format(yuming)
headers ={'Content-Type':'application/json;charset=UTF-8',
          'Accept':'application/json, text/javascript, */*; q=0.01',
          'Referer':'{0}/'.format(yuming)}
r=requests.get(url=url1,headers=headers)
repones=r.text
print('*'*100,'
','1-banner图-banner/findBanner','
','*'*100)
print()
print(r.status_code)
print(r.text)

如果参数比较多的话如何自动拼接呢

from urllib import parse

'''
1-banner图-banner/findBanner
'''
data1={
    'bannerType':1,
    '_':1556107073181
}
str1=parse.urlencode(data1)
url1='{0}/banner/findBanner?{1}'.format(yuming,str1)
headers ={'Content-Type':'application/json;charset=UTF-8',
          'Accept':'application/json, text/javascript, */*; q=0.01',
          'Referer':'{0}/'.format(yuming)}
r=requests.get(url=url1,headers=headers)
repones=r.text
print('*'*100,'
','1-banner图-banner/findBanner','
','*'*100)
print()
print(r.status_code)
print(r.text)
