嵌入消息未更新

Question

我想用嵌入的消息进行表决。
当有人添加反应时，我想添加一个喜欢并显示嵌入中的喜欢数量。这里是一个例子：

每当有人点击like时，我所有的代码行都会工作，而我最终将所链接的Field值更改为：

messageReaction.message.embeds[0].fields[0] = "Some much like";

但是嵌入消息不会更新。
我尝试使用以下方法更新消息：

function doAfakeEdit(message){
  message.edit(message.content);
}

它仍然保留该字段的旧值。
我该怎么办？

Answer 1

很晚的答案。但以防万一有人发现这个。有一个更短的方法。

如果您有大型嵌入并且不想重建整个嵌入，则更有用：

message.embeds[0].fields[0] = "Some much like";
message.edit(new Discord.RichEmbed(message.embeds[0]));

Answer 2

我想知道您的问题是否在于您是否正在重新使用变量名，将旧数据放回已编辑的消息中或其他原因。无论如何，这对我有用：

1）创建一个Embed发送给用户（我假设您已经做过，创建Embed您在imgr上显示的）：

const embed = new Discord.RichEmbed({
  title: 'Suggestion by someone',
  description: 'This is a test suggestion. Can you please like it or dislike it :)',
  fields: [{
    name: 'Like:',
    value: '<3'
  }]
});

2）发送Embed到您的频道（我在其中添加了一些Reaction内容-可能与您使用的方式相同）：

// add reaction emojis to message
message.channel.send(embed)
  .then(msg => msg.react('?'))
  .then(mReaction => mReaction.message.react('?'))
  .then(mReaction => {
    // fun stuff here
  })
  .catch(console.log);

3）ReactionCollector在我放置的地方创建一个内部// fun stuff here（可以使用不同的reactionFilter时间限制）：

const reactionFilter = (reaction, user) => reaction.emoji.name === '?';

// createReactionCollector - responds on each react, AND again at the end.
const collector = mReaction.message
  .createReactionCollector(reactionFilter, {
    time: 15000
  });

// set collector events
collector.on('collect', r => {
  // see step 4
});
// you can put anything you want here
collector.on('end', collected => console.log(`Collected ${collected.size} reactions`));

4）在这种情况'collect'下（我放置了// see step 4），创建一个Embed具有几乎相同值Embed的新消息（或者不-您可以更改所需的值），然后通过.edit(...)以下方式将该新消息放回原始消息中：

// immutably copy embed's 'Like:' field to new obj
let embedLikeField = Object.assign({}, embed.fields[0]);

// update 'field' with new value - you probably want emojis here
embedLikeField.value = '<3 <3 <3';

// create new embed with old title & description, new field
const newEmbed = new Discord.RichEmbed({
  title: embed.title,
  description: embed.description,
  fields: [embedLikeField]
});

// edit message with new embed
// NOTE: can only edit messages you author
r.message.edit(newEmbed)
  .then(newMsg => console.log(`new embed added`)) // this is not necessary
  .catch(console.log); // useful for catching errors

所以整个事情最终看起来像这样：

const reactionFilter = (reaction, user) => reaction.emoji.name === '?';

const embed = new Discord.RichEmbed({
  title: 'Suggestion by someone',
  description: 'This is a test suggestion. Can you please like it or dislike it :)',
  fields: [{
    name: 'Like:',
    value: '<3'
  }]
});

// add reaction emoji to message
message.channel.send(embed)
  .then(msg => msg.react('?'))
  .then(mReaction => mReaction.message.react('?'))
  .then(mReaction => {
    // createReactionCollector - responds on each react, AND again at the end.
    const collector = mReaction.message
      .createReactionCollector(reactionFilter, {
        time: 15000
      });

    // set collector events
    collector.on('collect', r => {
      // immutably copy embed's Like field to new obj
      let embedLikeField = Object.assign({}, embed.fields[0]);

      // update 'field' with new value
      embedLikeField.value = '<3 <3 <3';

      // create new embed with old title & description, new field
      const newEmbed = new Discord.RichEmbed({
        title: embed.title,
        description: embed.description,
        fields: [embedLikeField]
      });

      // edit message with new embed
      // NOTE: can only edit messages you author
      r.message.edit(newEmbed)
        .then(newMsg => console.log(`new embed added`))
        .catch(console.log);
    });
    collector.on('end', collected => console.log(`Collected ${collected.size} reactions`));
  })
  .catch(console.log);

对于我的代码，仅在？时进行编辑。按下表情符号只是为了好玩。如果您需要编辑以上代码的帮助，请告诉我。希望能帮助到你。
