• 首先，在根目录下创建一个.env.local文件，并在其中存储数据库凭据

MONGO_URI=mongodb://localhost:27017/netmapper

如果这不起作用，请将localhost替换为0.0.0.0

• 连接到mongo

async function connectToMongo() {
    try {
         await mongoose.connect(process.env.MONGO_URI);
         console.log("Connected to MongoDB");
       } catch (error) {
         console.error("Error connecting to MongoDB:", error);
         throw error;
        }
    };

• 创建架构

const testSchema = new Schema({
       name: String,
       email: String
    });

    const Test = models.Test|| model("Test", testSchema );

• 接受请求并通过创建api/xyz.js文件发送响应

async function handler(req, res) {
    if (req.method === "POST") {
        const data = req.body;

        try {
            await connectToMongo();
            await Test.create(data);

            res.status(201).json({ message: "Test Inserted!" });
        } catch (error) {
            res.status(500).json({ message: "Internal Server Error" });
        }
    }
};

• 最后发送您的表单数据

async function submitFormHandler(formData) {
    const response = await fetch("/api/xyz", {
      method: "POST",
      body: JSON.stringify(formData),
      headers: {
        "Content-Type": "application/json"
      }
    });

    const data = await response.json();
    console.log(data)
  }
