Firebase存储-上传Blob网址 [英] Firebase Storage - Upload Blob Url

问题描述

我有一个Blob网址，例如:

I have a blob url such as :

blob:http://localhost:4200/06a6baa9-b7ff-4171-9dc2-a1caed35e099

以及进入

  this.storage.ref('users/' + uid + '/mainPhoto').put(imageURL))

我收到此错误:

Firebase存储:put中索引0处的参数无效:预期的Blob或文件.

Firebase Storage: Invalid argument in put at index 0: Expected Blob or File.

推荐答案

您需要从Blob网址上传Blob， 然后将其上传到Firebase存储

You need to upload the blob from the blob url, and than upload it to firebase storage

上传功能:

uploadToStorage = (imageURL) = >{

     getFileBlob(imageURL, blob =>{
        firebase.storage().ref().put(blob).then(function(snapshot) {
           console.log('Uploaded a blob or file!');
        })
    })
}

getBlob函数:

var getFileBlob = function (url, cb) {
      var xhr = new XMLHttpRequest();
      xhr.open("GET", url);
      xhr.responseType = "blob";
      xhr.addEventListener('load', function() {
        cb(xhr.response);
      });
      xhr.send();
    };
