如何在Firebase中获取文档ID？

var db = firebase.firestore();

db.collection("your_collection").get().then((querySnapshot) => {
    querySnapshot.forEach((doc) => {
        console.log(doc.id);
    });
});

db.collection("your_collection").doc("your_document").get().then((doc) => {
    console.log(doc.id);
});

db.collection("your_collection").where("field", "==", "value").get().then((querySnapshot) => {
    querySnapshot.forEach((doc) => {
        console.log(doc.id);
    });
});
