Question

我已经使用JavaScript为Firebase创建了html表单。我有四个文本字段和一个时间戳。我有一个上传按钮，可以将文件（pdf）正确存储到Firebase存储器中。我想将Firebase存储中的文件的URL存储到Firestore数据库中。

我尝试了多种方法来获取URL并将其保存。我的问题似乎是“目的地：downloadUrl（signedUrl）”未存储文件的签名url，而是由于downloadUrl const导致了位置。我似乎无法弄清楚const上传实际网址所缺少的内容。我缺少语法上的某些内容，无法将手指放在上面。

const form = document.querySelector('#form_data');
const timestamp = firebase.firestore.FieldValue.serverTimestamp();
const downloadUrl = 'https://firebasestorage.googleapis.com/v0/b/company_info.appspot.com/Client_Uploads/o/';

  //var app = firebase.initializeApp(config);

// Initialize Firebase
var config = {
  apiKey: "Something",
  authDomain: "Something",
  databaseURL: "Something",
  projectId: "Something",
  storageBucket: "Something",
  messagingSenderId: "Something"
};
firebase.initializeApp(config);
const db = firebase.firestore();
var storageRef = firebase.storage().ref();

// saving data credit_union_referrals



form.addEventListener('submit', (e) => {
  e.preventDefault();

  var fileButton = document.getElementById('fileButton'); 

  var uploader = document.getElementById('uploader'); 

  fileButton.addEventListener ('change', async function(e) { 
  var file = e.target.files[0]; 
  var storageRef = firebase.storage().ref('Client_Uploads/' 
   + file.name);
  var task = storageRef.put(file);  

  const uploadOptions = {
    destination: uploadFilePath,
    public: true
  };
  let uploadedFile = await bucket.upload(tempThumbFilePath, uploadOptions)
  const signedUrls = await uploadedFile[0].getSignedUrl({action: 'read', expires: '01-01-4499'})
  const publicUrl = signedUrls[0];


  })


  db.collection("firestore_category").add({
      lname: form.lname.value,
      inlineFormCustomSelect: form.inlineFormCustomSelect.value,
      additionalinformation: form.additionalinformation.value,
      acceptance: form.acceptance.value,
      timestamp: firebase.firestore.FieldValue.serverTimestamp(),
  destination: downloadUrl(signedUr),

})
  .then(function(docRef) {
console.log("Referral successfully sent!", docRef.id);
  })
  .catch(function(error){
console.error("Error sending referral: ", error);
  });
  form.something.value = '';
  form.next.value = '';
  form.additionalinformation.value = '';
  form.acceptance.value = '';

})

预期结果是上载文件的url将保存到firestore数据库中。而是，文件会正确上传，但不会保存网址。任何帮助或指导，我们将不胜感激！
