我正在尝试service为reseller api包含oauth 2.0. Oauth 2.0 工作正常，因为我已经验证我可以获得access token. 我收到此错误消息是因为我找不到正确的经销商服务文档。尽管阅读了里面的代码apiclient.discovery.build，任何人都可以帮助我找出问题（问题在此消息的最后一部分）。
这是错误：
Traceback (most recent call last):
File "C:\Program Files (x86)\Google\google_appengine\lib\webapp2-2.5.2\webapp2.py", line 1535, in __call__
rv = self.handle_exception(request, response, e)

File "C:\xampp\htdocs\reseller-asteriainteractive\apiclient\discovery.py", line 583, in method
raise TypeError('Missing required parameter "%s"' % name)
TypeError: Missing required parameter "body"
这是我的代码：
class CustomerCreateHandler(BaseHandler):
@decorator.oauth_aware
def post(self):
admin_user = users.is_current_user_admin()
user = users.get_current_user()
if user:
if decorator.has_credentials():
customers = reseller_service.customers()
customer_document = customers.insert().execute(decorator.http())
self.redirect('/customer/create/')
reseller_service 应该如何构建？我应该把“body”参数放在哪里？
