推荐答案

要能够在Flutter网页上显示Firebase存储中的图像，您必须为

For being able to display your images from Firebase Storage on a Flutter web page you have to configure your data for CORS.

1. 打开 GCP控制台，选择您的项目并通过点击> _ 图标按钮.
2. 单击打开的编辑器按钮(铅笔图标)，然后创建 cors.json 文件.
3. 运行 gsutil cors set cors.json gs://您的桶

1. Open the GCP console, select your project and start a cloud terminal session by clicking the >_ icon button in the top navbar.
2. Click the open editor button (pencil icon), then create the cors.json file.
3. Run gsutil cors set cors.json gs://your-bucket

cors.json 文件应如下所示:

[
  {
    "origin": ["*"],
    "method": ["GET"],
    "maxAgeSeconds": 3600
  }
]

我将原点设置为 * ，这意味着每个网站都可以显示您的图像.但是您也可以在其中插入网站的域以限制访问.

I set the origin to * which means that every website can display your images. But you can also insert the domain of your website there to restrict the access.
