Microsoft Graph API returns 邮件正文为 HTML

Question

我想阅读我的电子邮件并将它们转换成 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();

我按照 this 教程进入了这个阶段。但是我的邮件正文被 return 编辑为 html 而不是文本。有没有一种方法可以指定 message.body 到 return 文本甚至 json 而不是 HTML？

Answer 1

不用设置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://docs.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class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 link 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;
 }

使用 GraphServiceClient，调用 .Header("Prefer", "outlook.body-content-type='text'") 作为请求方法链的一部分：

var mailResults = await client.Me.MailFolders.Inbox.Messages
                                .Request()
                                .Header("Prefer", "outlook.body-content-type='text'")
                                .OrderBy("receivedDateTime DESC")
                                .Select(m => new { m.Subject, m.ReceivedDateTime, m.From, m.Body})
                                .Top(100)
                                .GetAsync();
