Python Boto - 如何为 Route 53 创建健康检查

Question

我想知道怎么用Python的boto库为Route53创建一个健康检查。网上没有例子，文档也很少，真让人头疼。http://boto.readthedocs.org/en/latest/ref/route53.html

那么，如果给我一个IP地址、端口和路径，我该怎么办呢？

虽然 boto 的文档不太完善，但你可以通过 代码 和 AWS 的 API 来理解它。

看看 boto.route53.healthcheck.HealthCheck，然后按照下面的方式来实现：

route = boto.connect_route53()
hc = boto.route53.healthcheck.HealthCheck(...)
route = create_health_check(hc)

... 的内容可以通过 HealthCheck 的 帮助页面 来填写：
