How to get document by id in google firestore? is there some get() method? because I searched but didn't find a proper answer that suits to me :(

更新:this.itemscollection.doc(id).get()不适用于我

推荐答案

尝试此代码

this.itemscollection.doc(id).ref.get().then(function(doc) {
  if (doc.exists) {
    console.log("Document data:", doc.data());
  } else {
    console.log("No such document!");
  }
}).catch(function(error) {
  console.log("Error getting document:", error);
});
