Google Cloud Storage - 如何直接从浏览器上传内容 (JavaScript)

Question

如何直接从浏览器 (JavaScript) 上传内容到 GC 存储？ 是否有一些简单的方法可以使用令牌（在 URL/cookies 中）或类似方法？

注意：不考虑任何中间系统（如 URL 签名者）。我正在寻找一种从 JS 发送请求并在 GC 存储中处理它的方法。

如果不是，您知道不引入太多依赖项和复杂性的最简单解决方案是什么？

Answer 1

这很容易。您可以使用 Firebase JavaScript SDK 在网络上执行此操作。

文档中的代码

var uploadTask = storageRef.child('images/rivers.jpg').put(file);

// Register three observers:
// 1. 'state_changed' observer, called any time the state changes
// 2. Error observer, called on failure
// 3. Completion observer, called on successful completion
uploadTask.on('state_changed', function(snapshot){
  // Observe state change events such as progress, pause, and resume
  // Get task progress, including the number of bytes uploaded and the total number of bytes to be uploaded
  var progress = (snapshot.bytesTransferred / snapshot.totalBytes) * 100;
  console.log('Upload is ' + progress + '% done');
  switch (snapshot.state) {
    case firebase.storage.TaskState.PAUSED: // or 'paused'
      console.log('Upload is paused');
      break;
    case firebase.storage.TaskState.RUNNING: // or 'running'
      console.log('Upload is running');
      break;
  }
}, function(error) {
  // Handle unsuccessful uploads
}, function() {
  // Handle successful uploads on complete
  // For instance, get the download URL: https://firebasestorage.googleapis.com/...
  uploadTask.snapshot.ref.getDownloadURL().then(function(downloadURL) {
    console.log('File available at', downloadURL);
  });
});
