安装yaml：
pip install pyyaml
写入yaml：
import json
from ruamel import yaml
aproject ={'cardBalance': 18850}
aproject2 ={"cardNumber": "22222222"}
# # print(aproject)
# # def th(cas):
# # f = open(r'te.yml','r+')
# # test=(yaml.dump(cas,f)) # 转换json str
# # f.close()
# def th(ca):
# with open('te.yml', 'r+') as f:
# f.write(yaml.dump(ca,Dumper=yaml.RoundTripDumper))
with open('te.yml', 'r+',encoding="utf-8") as f:
# 生产字典 如果不使用 Dumper=yaml.RoundTripDumper 写入的数据yml是带{a：124}
f.write(yaml.dump(aproject,Dumper=yaml.RoundTripDumper))
f.write(yaml.dump(aproject2, Dumper=yaml.RoundTripDumper))
读取：
import yaml, requests, json
import requests
d = open('b1.yml')
e = yaml.load(d) #转换成字典格式
request = e['request1'] #取这个字典值
print(request)
# # # name = e['name']
# # # method = request['method']
url = request['url']
# print(url)
# # # # # headers = request['headers']
# data = request['data']
# print(data)
test=json.dumps(request['data'])
print(test)
re = requests.post(url,data=test)
print(re.text)
