上传时 Firebase 存储无效参数

Question

我不断收到Invalid argument in put at index 0: Expected Blob or File 错误。有趣的是参数完全是一个文件......

代码如下：

var file = document.getElementById('cke_69_fileInput')
          .contentWindow.document.getElementById('cke_69_fileInput_input').files[0];

var storageUrl = 'noticias/imagenes/';
var storageRef = firebase.storage().ref(storageUrl + file.name);
console.warn(file); // Watch Screenshot
var uploadTask = storageRef.put(file);

这是在请求文件的错误之前发出的实际文件警告的屏幕截图...

Answer 1

尝试将文件转换为 blob...

  var reader = new FileReader();
  reader.onloadend = function (evt) {
    var blob = new Blob([evt.target.result], { type: "image/jpeg" });

    var storageUrl = 'noticias/imagenes/';
    var storageRef = firebase.storage().ref(storageUrl + file.name);
    console.warn(file); // Watch Screenshot
    var uploadTask = storageRef.put(blob);

  }

  reader.onerror = function (e) {
      console.log("Failed file read: " + e.toString());
  };
  reader.readAsArrayBuffer(file);
