print(request.method) # POST 看来可以使用这种方式来验证请求方式了

    print(request.args)  # ImmutableMultiDict([('id', '1'), ('age', '20')])print(request.args["id"])  # 1print(request.args.get("age"))  # 20print(list(request.args.keys()))  # ['id', 'age']print(list(request.args.values()))  # ['1', '20']req_dict = dict(request.args)  # {'id': ['1'], 'age': ['20']}print(req_dict)

print(request.values)  # CombinedMultiDict([ImmutableMultiDict([('id', '1'), ('age', '20')]), ImmutableMultiDict([('user', 'Oldboy'), ('pwd', 'DragonFire')])])
print(request.values.get("id"))  # 1
print(request.values["user"])  # Oldboy
# 这回喜欢直接操作字典的小伙伴们有惊喜了! to_dict() 方法可以直接将我们的参数全部转为字典形式
print(request.values.to_dict()) # {'user': 'Oldboy', 'pwd': 'DragonFire', 'id': '1', 'age': '20'}

# 注意这里的坑来啦! 坑来啦!
# 如果url和form中的Key重名的话,form中的同名的key中value会被url中的value覆盖
# http://127.0.0.1:5000/req?id=1&user=20
print(request.values.to_dict())  # {'user': 20 'pwd': 'DragonFire', 'id': '1'}
