c# - Microsoft Graph API 以 HTML 格式返回邮件正文

Question

我想阅读我的电子邮件并将它们转换为 json。我正在使用 Microsoft Graph API像这样查询office 365邮箱

GraphServiceClient client = new GraphServiceClient(
            new DelegateAuthenticationProvider (
                (requestMessage) =>
                    {
                        requestMessage.Headers.Authorization =
                                            new AuthenticationHeaderValue("Bearer", token);
                        return Task.FromResult(0);
                    }
                )
            );

var mailResults = await client.Me.MailFolders.Inbox.Messages.Request()
                                .OrderBy("receivedDateTime DESC")
                                .Select(m => new { m.Subject, m.ReceivedDateTime, m.From, m.Body})
                                .Top(100)
                                .GetAsync();

我关注了this进入这个阶段的教程。但是我的邮件正文以 html 而不是文本形式返回。有没有一种方法可以指定 message.body 返回文本甚至 json 而不是 HTML？

不是必须要设置HTTP请求头吗:

Prefer: outlook.body-content-type="text"

requestMessage.Headers.Add("Prefer", "outlook.body-content-type='text'");

根据文档 https://learn.microsoft.com/en-us/previous-versions/office/office-365-api/api/version-2.0/mail-rest-operations

编辑:

查看文档，这是客户端类代码:https://github.com/microsoftgraph/msgraph-sdk-dotnet/blob/dev/src/Microsoft.Graph/Requests/Generated/GraphServiceClient.cs

这是您正在关注的链接中的示例:

private static GraphServiceClient GetClient(string accessToken, IHttpProvider provider = null)
{
        var delegateAuthProvider = new DelegateAuthenticationProvider((requestMessage) =>
        {
            requestMessage.Headers.Authorization = new AuthenticationHeaderValue("bearer", accessToken);

            return Task.FromResult(0);
        });

        var graphClient = new GraphServiceClient(delegateAuthProvider, provider ?? HttpProvider);

        return graphClient;
 }
