使用 MapiMessage 进行投票选项操作

使用 MapiMessage 创建投票选项

Microsoft Outlook 允许用户在撰写新邮件时创建投票，并可包含诸如“是”“否”“可能”等投票选项。Aspose.Email 在创建新 Outlook 邮件时也提供相同功能。 FollowUpOptions class 提供了 VotingButtons 属性，可用于设置或获取投票选项的值。本文提供了创建 MapiMessage 包含投票选项以创建投票。

使用 MapiMessage 创建投票

以下代码片段展示如何创建投票， FollowUpManager 该类可按以下代码片段所示使用。

// For complete examples and data files, please go to https://github.com/aspose-email/Aspose.Email-for-Java
String address = "[e-mail]";
IEWSClient client = EWSClient.getEWSClient("https://outlook.office365.com/ews/exchange.asmx", "testUser", "pwd", "domain");
MailMessage message = createTestMessage(address);

// Set FollowUpOptions Buttons
FollowUpOptions options = new FollowUpOptions();
options.setVotingButtons("Yes;No;Maybe;Exactly!");
client.send(message, options);

从 MapiMessage 读取投票选项

以下代码片段展示如何从 MapiMessage.

// For complete examples and data files, please go to https://github.com/aspose-email/Aspose.Email-for-Java
// The path to the File directory.
String fileName = "outlook/message.msg";

MapiMessage message = MapiMessage.fromFile(fileName);

// This method can be useful when except voting buttons it is necessary to get other parameters (ex. a category)
FollowUpOptions options = FollowUpManager.getOptions(message);

// Voting buttons will be introduced as a string with semi-column as a separator
String votingButtons = options.getVotingButtons();

仅读取投票按钮

以下代码片段展示如何仅读取投票按钮。

// For complete examples and data files, please go to https://github.com/aspose-email/Aspose.Email-for-Java
InputStream ms = new FileInputStream(dataDir + "MapiMsgWithPoll_out.msg");
MapiMessage testMsg = MapiMessage.fromStream(ms);

// This method can be useful when it is necessary to read only voting buttons
// Voting buttons will be introduced as a collection of string values
IList buttons = FollowUpManager.getVotingButtons(testMsg);

向现有消息添加投票按钮

以下代码片段展示如何向现有消息添加投票按钮。

// For complete examples and data files, please go to https://github.com/aspose-email/Aspose.Email-for-Java
// The path to the File directory.
String dataDir = "outlook/";

MapiMessage mapi = MapiMessage.fromFile(dataDir + "message.msg");
FollowUpManager.addVotingButton(mapi, "Indeed!");
mapi.save(dataDir + "AddVotingButtonToExistingMessage_out.msg");

从消息中删除投票按钮

以下代码片段展示如何从消息中删除投票按钮。

// For complete examples and data files, please go to https://github.com/aspose-email/Aspose.Email-for-Java
// The path to the File directory.
String dataDir = "outlook/";

// Create New Message and set FollowUpOptions, FollowUpManager properties
MapiMessage msg = createTestMessage(false);

FollowUpOptions options = new FollowUpOptions();
options.setVotingButtons("Yes;No;Maybe;Exactly!");
FollowUpManager.setOptions(msg, options);
msg.save(dataDir + "MapiMsgWithPoll.msg");
FollowUpManager.removeVotingButton(msg, "Exactly!"); // Deleting a single button OR
FollowUpManager.clearVotingButtons(msg); // Deleting all buttons from a MapiMessage
msg.save(dataDir + "MapiMsgWithPoll.msg");

读取投票结果信息

以下代码片段展示如何读取投票结果信息。

// For complete examples and data files, please go to https://github.com/aspose-email/Aspose.Email-for-Java
// The path to the File directory.
String dataDir = "outlook/";

MapiMessage msg = MapiMessage.fromFile(dataDir + "AddVotingButtonToExistingMessage.msg");
for (MapiRecipient recipient : msg.getRecipients()) {
    System.out.println("Recipient: " + recipient.getDisplayName());

    // Get the PR_RECIPIENT_AUTORESPONSE_PROP_RESPONSE property
    System.out.println("Response: " + recipient.getProperties().get_Item(MapiPropertyTag.PR_RECIPIENT_AUTORESPONSE_PROP_RESPONSE).getString());

    // Get the PR_RECIPIENT_TRACKSTATUS_TIME property
    System.out.println("Response time: " + recipient.getProperties().get_Item(MapiPropertyTag.PR_RECIPIENT_TRACKSTATUS_TIME).getDateTime());

    System.out.println();
}

示例中使用的方法

以下代码片段展示如何创建示例中使用的示例消息。

// For complete examples and data files, please go to https://github.com/aspose-email/Aspose.Email-for-Java
public static MapiMessage createTestMessage(boolean draft) {
    MapiMessage msg = new MapiMessage("[e-mail]", "[e-mail]", "Flagged message",
            "Make it nice and short, but descriptive. The description may appear in search engines' search results pages...");

    if (!draft) {
        msg.setMessageFlags(msg.getFlags() ^ MapiMessageFlags.MSGFLAG_UNSENT);
    }
    return msg;
}
