如何解决等待消息中未处理的 Promise 拒绝？

Question

我在控制台中收到此错误：

我已将问题缩小到我的代码的这一部分：

for (var x = 0; x < questions.length; x++) {
        message.author
          .send({
            embed: {
              title: `***Q${x + 1}. ${questions[x]}***`,
              description:
                "Please answer questions honestly and if asked about your details, please provide REAL life details",
              footer: {
                text: "You have 1 minute to answer questions!",
              },
              color: 0xe556f5,
            },
          })
          .then((msg) => {
            dmCh = msg.channel;
          })
          .catch((err) => {
            message.author.send("Some error occurred");
          });
          dmCh.awaitMessages({ max: 1, time: 60000 })
            .then((answer) => {
              // answers.append(answer.toLowerCase());
              console.log(answer);
            })
            .catch((collected) => {
              // console.log(collected);
            });
      }

我已经尝试过我的机器人的其他命令，它们工作正常，但是一旦我运行这个命令，它就会给出上述错误，之后，如果我在频道中输入任何消息，它就会给出这个错误。 我还尝试在我的代码周围放置一个 try 和 catch 块，如下所示：

try {
          dmCh.awaitMessages({ max: 1, time: 60000 })
            .then((answer) => {
              // answers.append(answer.toLowerCase());
              console.log(answer);
            })
            .catch((collected) => {
              // console.log(collected);
            });
        } catch (e) {
          console.log(e);
        }

但它不起作用。

请帮帮我！

Answer 1

问题中显示的代码中唯一看起来可能会产生未处理拒绝的部分是

message.author.send("Some error occurred");

在catch 处理程序中。如果这引发错误，它将拒绝来自catch 的承诺，并且该拒绝不会在任何地方得到处理。

您可以通过添加第二个catch 处理程序或在您拥有的catch 处理程序中使用try/catch 来捕获该拒绝：

.catch(err => {
    try {
        message.author.send("Some error occurred");
    } catch (e) {
        // ...
    }
});

如果send 返回一个承诺，则不会处理该承诺。要同时处理抛出异常和来自send 的拒绝，返回send 的结果并添加第二个catch 处理程序：

.catch(err => {
    return message.author.send("Some error occurred");
})
.catch(err => {
    // Do whatever you want to do when the error handling failed
});

---

但也有可能您正在调用的某个函数正在创建一个它没有传递回您的代码的承诺，并且未能处理对该承诺的拒绝。

发生错误是因为您没有提供filter 函数。

这是文档中的一个示例

// Await !vote messages
const filter = m => m.content.startsWith('!vote');

// Errors: ['time'] treats ending because of the time limit as an error
channel.awaitMessages({ filter, max: 4, time: 60000, errors: ['time'] })
  .then(collected => console.log(collected.size))
  .catch(collected => console.log(`After a minute, only ${collected.size} out of 4 voted.`));

DmChannel#awaitMessages() (v13) 上的文档

如果您使用的是 v12

channel.awaitMessages(filter, { max: 4, time: 60000, errors: ['time'] }) //...
