推荐答案

以下代码段显示了如果有URL，如何将图像直接上传到Cloud Storage.任何公共链接都可以使用，无论它是从Dropbox共享还是在互联网上的其他地方共享.

Here's a snippet of code that shows how you could upload a image directly to Cloud Storage if you have a URL for it. Any public link works, whether it's shared from Dropbox or somewhere else on the internet.

编辑2020-06-01 :直接从URL上传的选项已在SDK的v2.0版本中删除(2018年9月4日):

Edit 2020-06-01 The option to upload directly from URL was dropped in v2.0 of the SDK (4 September 2018): https://github.com/googleapis/nodejs-storage/releases/tag/v2.0.0

const fileUrl = 'https://www.dropbox.com/some/file/download/link.jpg';
const opts = {
  destination: 'path/to/file.jpg',
  metadata: {
    contentType: 'image/jpeg'
  }
};

firebase.storage().bucket().upload(fileUrl, opts);

此示例使用的是应用程序中的默认存储桶，并且opts对象为API调用提供了文件上传选项.

This example is using the default bucket in your application and the opts object provides file upload options for the API call.

• destination是您的文件将被上传到Google Cloud Storage中的路径
• metadata应该描述您要上传的文件( MIME类型您要上传的

• destination is the path that your file will be uploaded to in Google Cloud Storage
• metadata should describe the file that you're uploading (see more examples here)
  • contentType is the file MIME type that you are uploading
