如何使用C＃Microsoft.Graph创建回复？

Question

我正在尝试在Outlook帐户上回复电子邮件。 但是，当我尝试创建答复（尚未发送）时，出现以下异常：

ServiceException：代码：RequestBroker--ParseUri

消息：找不到段“ microsoft.graph.createReply”的资源。

显然，问题出在Url中，但没有意义，因为当我尝试在创建回复之前尝试获取消息时，除我尝试为该消息创建回复外，其他所有操作都有效。

这是代码：

ConfidentialClientApplication cca = new ConfidentialClientApplication(
    [client_id], [redirect_uri],
    new ClientCredential([secret]),
    new TokenCache(), null);

string[] scopes = new string[]
{
    "email",
    "https://outlook.office.com/mail.read",
    "https://outlook.office.com/mail.read.shared",
    "https://outlook.office.com/mail.readwrite",
    "https://outlook.office.com/mail.readwrite.shared",
    "https://outlook.office.com/mail.send",
    "https://outlook.office.com/mail.send.shared"
};

AuthenticationResult result = (cca as IByRefreshToken).AcquireTokenByRefreshTokenAsync(scopes, [refresh_token]).Result;

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

string id = [message_id];
Message details = client
    .Me
    .Messages[id]
    .Request()
    .GetAsync()
    .Result; // JUST FOR TESTING, THIS WORKS!
Message reply = client
    .Me
    .Messages[id]
    .CreateReply()
    .Request()
    .PostAsync().Result; // THIS FAILS!!!

reply.Body.ContentType = BodyType.Html;
reply.Body.Content = [html_code];

client
    .Me
    .Messages[reply.Id]
    .Request()
    .UpdateAsync(reply); // HOPE THIS WORKS

client
    .Me
    .Messages[reply.Id]
    .Send()
    .Request()
    .PostAsync()
    .Wait(); // HOPE THIS WORKS TOO

我正在使用.NET 4.7.2，Microsoft.Graph 1.17和Microsoft.Identity.Client v3.0.2-preview（这是因为，如果我尝试使用任何稳定的版本，都会收到错误消息，尝试仅使用刷新令牌）

您正在混合两个API。 Microsoft Graph SDK旨在与Microsoft Graph一起使用，而不是与Outlook REST API一起使用。 尽管它们几乎相同，但是无疑会遇到问题（特别是反序列化对象）。 您应该请求图作用域和图端点。

ConfidentialClientApplication cca = new ConfidentialClientApplication(
    [client_id], [redirect_uri],
    new ClientCredential([secret]),
    new TokenCache(), null);

string[] scopes = new string[]
{
    "mail.read",
    "mail.readwrite",
    "mail.send",
};

AuthenticationResult result = (cca as IByRefreshToken).AcquireTokenByRefreshTokenAsync(scopes, [refresh_token]).Result;

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

string id = [message_id];

Message reply = client
    .Me
    .Messages[id]
    .CreateReply()
    .Request()
    .PostAsync().Result; 

client
    .Me
    .Messages[reply.Id]
    .Request()
    .UpdateAsync(new Message() {
        Body = new ItemBody() {
            Content = msg.Body,
            ContentType = BodyType.Html 
        }
     })
    .Wait(); // You have to use a new object and define only the fields you want to change

client
    .Me
    .Messages[reply.Id]
    .Send()
    .Request()
    .PostAsync()
    .Wait();

查看此客户端库：

https://github.com/ivfranji/GraphManagedApi

它具有在消息上生成的用于创建回复的方法：

消息msg = MailboxBMessages.Items [0];

等待msg.Reply（“这是我的答复”）;
