我想列出对 Discord 做出反应的用户。

let MyChannel = client.channels.get('573534660852711426');
    MyChannel.fetchMessage('656352072806957066').then(themessage => {
    for (const reaction of themessage.reactions){
        for (let user of reaction.users){
            console.log(user);
        }
        console.log(reaction);
    }
});

这是我的代码，但它不起作用。你能帮帮我吗？

谢谢。

当你说它不起作用时，它会给你一个错误、一个不正确的答案还是什么都没有发生？

我运行代码时遇到的错误如下。

    at F:\js\index.js:41:37
    at processTicksAndRejections (internal/process/task_queues.js:93:5)
(node:23364) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 2)

39      MyChannel.fetchMessage('650431271436156969').then(async themessage => {
40          for (const reaction of themessage.reactions){
41              for (let user of await reaction.fetchUsers()){
42                  console.log(user);
43              }
44              console.log(reaction);
45          }
46      });

【解决方案2】：

您需要使用Reaction.fetchUsers。试试这样的：

let MyChannel = client.channels.get('573534660852711426');
    MyChannel.fetchMessage('656352072806957066').then(async themessage => {
    for (const reaction of themessage.reactions){
        for (let user of await reaction.fetchUsers(){
            console.log(user);
        }
        console.log(reaction);
    }
});

我用await reaction.fetchUsers() 编辑了reaction.users 并添加了async，因为await 必须在异步函数中使用。
