// 引入Firebase SDK
<script src="https://www.gstatic.com/firebasejs/9.6.1/firebase-app.js"></script>
<script src="https://www.gstatic.com/firebasejs/9.6.1/firebase-firestore.js"></script>

// 初始化Firebase应用程序
<script>
  const firebaseConfig = {
    apiKey: "YOUR_API_KEY",
    authDomain: "YOUR_AUTH_DOMAIN",
    projectId: "YOUR_PROJECT_ID",
    storageBucket: "YOUR_STORAGE_BUCKET",
    messagingSenderId: "YOUR_MESSAGING_SENDER_ID",
    appId: "YOUR_APP_ID"
  };

  firebase.initializeApp(firebaseConfig);
</script>

const db = firebase.firestore();

// 添加文档到集合中
db.collection("your_collection_name").add({
  field1: "value1",
  field2: "value2"
})
.then((docRef) => {
  console.log("文档已添加，文档ID为：", docRef.id);
})
.catch((error) => {
  console.error("添加文档时出错：", error);
});

const docRef = db.collection("your_collection_name").doc("your_document_id");

// 更新文档中的字段
docRef.update({
  field1: "new_value1",
  field2: "new_value2"
})
.then(() => {
  console.log("文档已更新");
})
.catch((error) => {
  console.error("更新文档时出错：", error);
});
