我正在用 Javascript 开发一个 Discord 机器人项目。要部署我的命令，我必须将它们注册到我的 index.js 文件中。这是我的项目的结构：
类似这样的事情。
但是我有这个错误：
TypeError: Do not know how to serialize a BigInt这是我的index.js 文件：
const {
Client,
Collection,
Intents,
GatewayIntentBits,
} = require("discord.js");
const fs = require("fs");
const { token } = require("./config.json");
// Create a new Discord client
const client = new Client({
intents: [
GatewayIntentBits.Guilds,
GatewayIntentBits.GuildMessages,
GatewayIntentBits.MessageContent,
GatewayIntentBits.GuildMembers,
],
});
// Set up a collection to hold your command files
client.commands = new Collection(); // define commands collection here
const commandFolders = fs.readdirSync("./commands");
for (const folder of commandFolders) {
const commandFiles = fs
.readdirSync(`./commands/${folder}`)
.filter((file) => file.endsWith(".js"));
for (const file of commandFiles) {
const command = require(`./commands/${folder}/${file}`);
client.commands.set(command.name, command); // use client.commands instead of commands
}
}
// Set up event listeners for when the client is ready and when it receives a command interaction
client.once("ready", async () => {
console.log(`Logged in as ${client.user.tag}!`);
// Register slash commands
try {
const commandData = Array.from(client.commands.values()).map((command) => {
const data = { ...command };
if (typeof data.defaultPermission === "boolean") {
data.defaultPermission = String(data.defaultPermission);
}
return data;
});
await client.application.commands.set(commandData);
console.log("Successfully registered application commands.");
} catch (error) {
console.error("Failed to register application commands:", error);
}
});
client.on("interactionCreate", async (interaction) => {
if (!interaction.isCommand()) return;
const command = client.commands.get(interaction.commandName); // use client.commands instead of commands
if (!command) return;
try {
await command.execute(interaction);
} catch (error) {
console.error(error);
await interaction.reply({
content: "There was an error while executing this command!",
ephemeral: true,
});
}
});
// Log in to Discord with your bot token
client.login(token);
这是精确的输出：
Logged in as botname#0000 !

编辑：
这是造成麻烦的文件：
const { Discord, PermissionFlagsBits } = require("discord.js");
const { MongoClient, ServerApiVersion } = require("mongodb");
const uri =
"urltoconnectdatabase";
const client = new MongoClient(uri, {
useNewUrlParser: true,
useUnifiedTopology: true,
serverApi: ServerApiVersion.v1,
});
module.exports = {
name: "createcharacter",
description: "Create your character",
options: [
{
name: "permission",
description: "Permission level",
type: "INTEGER",
required: true,
choices: [
{
name: "Administrator",
value: PermissionFlagsBits.Administrator,
},
],
},
],
async execute(interaction) {
const userId = interaction.user.id;
await interaction.reply("What's your character's name?");
const name = await interaction.channel.awaitMessages({
filter: (m) => m.author.id === interaction.user.id,
max: 1,
time: 30000,
});
await interaction.reply("What's your character's house?");
const house = await interaction.channel.awaitMessages({
filter: (m) => m.author.id === interaction.user.id,
max: 1,
time: 30000,
});
await interaction.reply("What's your character's wand?");
const wand = await interaction.channel.awaitMessages({
filter: (m) => m.author.id === interaction.user.id,
max: 1,
time: 30000,
});
await interaction.reply("What's your character's patronus?");
const patronus = await interaction.channel.awaitMessages({
filter: (m) => m.author.id === interaction.user.id,
max: 1,
time: 30000,
});
client.connect().then(
// success
() => {
console.log("Connection successful");
const collection = client.db("WizardryBot").collection("characters");
let documentToInsert = {
userId: userId.toString(),
name: name.first().content,
house: house.first().content,
wand: wand.first().content,
patronus: patronus.first().content,
experience: 0,
money: 0,
quidditchxp: 0,
};
function userOwnCharacter(userId) {
return collection
.findOne({ userId: userId })
.then((result) => Promise.resolve(result !== null))
.catch((err) => {
console.error(err);
});
}
userOwnCharacter(userId)
.then((result) => {
if (result) {
console.log("User owns a character");
return Promise.resolve();
} else {
console.log("User does not own any character");
return collection.insertOne(documentToInsert).then(
(insertedDocument) => {
console.log("Data inserted");
// console.log(JSON.stringify(insertedDocument, null, 2));
const characterEmbed = new Discord.MessageEmbed()
.setTitle("Character Information")
.addField("Name", name.first().content)
.addField("House", house.first().content)
.addField("Wand", wand.first().content)
.addField("Patronus", patronus.first().content)
.setColor("#0099ff");
interaction.reply({ embeds: [characterEmbed] });
return Promise.resolve();
},
(reason) => {
console.log("Failed to insert document", reason);
return Promise.reject(reason);
}
);
}
})
.finally(() => {
console.log("Closing db connection");
client.close();
});
},
// failure
(reason) => {
// Connection failed with reason
console.log("Connection failed", reason);
}
);
},
};
这是我的index.js :
const {
Client,
Collection,
Intents,
GatewayIntentBits,
} = require("discord.js");
const fs = require("fs");
const { token } = require("./config.json");
// Create a new Discord client
const client = new Client({
intents: [
GatewayIntentBits.Guilds,
GatewayIntentBits.GuildMessages,
GatewayIntentBits.MessageContent,
GatewayIntentBits.GuildMembers,
],
});
// Set up a collection to hold your command files
client.commands = new Collection(); // define commands collection here
const commandFolders = fs.readdirSync("./commands");
for (const folder of commandFolders) {
const commandFiles = fs
.readdirSync(`./commands/${folder}`)
.filter((file) => file.endsWith(".js"));
for (const file of commandFiles) {
const command = require(`./commands/${folder}/${file}`);
client.commands.set(command.name, command); // use client.commands instead of commands
}
}
// Set up event listeners for when the client is ready and when it receives a command interaction
client.once("ready", async () => {
console.log(`Logged in as ${client.user.tag}!`);
// Register slash commands
try {
const commandData = Array.from(client.commands.values()).map((command) => {
const data = { ...command };
if (typeof data.defaultPermission === "boolean") {
data.defaultPermission = String(data.defaultPermission);
}
// Convert any BigInt values to string
if (typeof data.id === "bigint") {
data.id = data.id.toString();
}
return data;
});
await client.application.commands.set(commandData);
console.log("Successfully registered application commands.");
} catch (error) {
console.error("Failed to register application commands:", error);
}
});
client.on("interactionCreate", async (interaction) => {
if (!interaction.isCommand()) return;
const command = client.commands.get(interaction.commandName); // use client.commands instead of commands
if (!command) return;
try {
await command.execute(interaction);
} catch (error) {
console.error(error);
await interaction.reply({
content: "There was an error while executing this command!",
ephemeral: true,
});
}
});
// Log in to Discord with your bot token
client.login(token);
好的，我解决了我的错误。在我的代码中，我不需要以下部分：
options: [
{
name: "permission",
description: "Permission level",
type: "INTEGER",
required: true,
choices: [
{
name: "Administrator",
value: PermissionFlagsBits.Administrator,
},
],
},
],
所以我把它删除了。现在可以了！ 感谢您的帮助！
在主文件中我简单地转换它
declare global {
interface BigInt {
toJSON(): Number;
}
}
BigInt.prototype.toJSON = function () { return Number(this) }
我在进行玩笑测试时遇到了这个错误。
发生此错误时的示例：
expect(BigInt('1.2345')).toBe('1.2345'); // BigInt vs String
因此，如果您有条件，请检查它们并将它们重新定义为单一类型。
