在后端C#中 call web api

标签：coding method default protoc 数据 tps intvalue pre tty 我们要想使用web api, 需要首先在azure 中创建application. (如何创建application可以参考我的另一篇blog 从O365中获取users到D365中 ) Get 我们可以用JObject 和 JArray 来快速获取而不需要DeserializeObject POST: ServicePointManager.SecurityProtocol 是必须要添加的. 不然会抛出 security 的exception. req.Headers.Add("If-Match", "*"); 如果我们在请求的表头里添加了 if-match的话, 如果有相同的record创建时,会抛出 exception 412 error 而不会去创建一条一模一样的数据.
