使用 C# Office Graph SDK 客户端指定请求标头

Question

I am interacting with Office graph using C# Office Graph SDK. I need to create specific request header, while I am using GraphServiceClient and RequestBuilder to create the request. How can I achieve that?

Answer 1

To set custom header for the request, you need to create Option collection. To add headers, you need to add new item of type HeaderOption to this collection. See code sample bellow:

List<Option> options = new List<Option>
{
   //Creating query parameters
   new QueryOption("filter", $"(start/dateTime le '{DateTime.Now.AddMinutes(5).ToString("yyyy-MM-ddTHH:mm")}')),

   //Creating header
   new HeaderOption("Prefer","outlook.timezone=\"Europe/Budapest\"")
};

var res = await graphClient.Users["userId"].Events.Request(options).GetAsync();
