Azure cosmosdb 创建删除database,container和增删改查操作

本文代码摘自cosmosdb官网，然后仿照着自己添加了一个删除container的函数，记录在此以便查阅。

想自行尝试的话可以去Home - Microsoft Azure官网按照教程操作一遍，会自动下载一个项目到本地，然后自己跑跑就好了：

 其实核心思路就是：

1. 首先创建一个用于连接azure cosmosdb的cosmosclient实例
2. 然后就利用cosmosclient上提供的API进行各种操作

常用的操作包含下如下几个函数里，可以自行查看：

CreateDatabaseAsync();  // 创建database
CreateContainerAsync();  // 创建container，可以理解为创建表
ScaleContainerAsync();  // 设置吞吐量
AddItemsToContainerAsync();  // 插入一条记录
QueryItemsAsync();   // 查询一条记录
ReplaceFamilyItemAsync();  // 修改
DeleteFamilyItemAsync();  // 删除
DeleteContainerAndCleanupAsync();  // 删除container
DeleteDatabaseAndCleanupAsync();  // 删除数据库
