我在 rinkeby etherscan 网络上运行我的代码，它运行良好。但是图像和描述没有显示在 opensea 测试网上。我运行它显示的 /validate/ url Valid: "false"。

这是我在 opensea 上强制更新时发现的内容，https: //testnets-api.opensea.io/api/v1/asset/0x668D179B933af761e4732B084290D32B3235C22b/0/?force_update=true

这是我的代码：

as you can see in the right up corner there is a "reload" button, you need to click it to reload the ipfs on opensea

我有同样的问题。原来我没有正确地将图像上传到 ipfs，因为它只在我的机器上对我可见。因此，请尝试查看 ipfs 元数据的格式是否正确，并且是否可以从不同的设备访问。

此外，您不应该只是粘贴您的整个合同。Tt 真的很难回答您的问题。只需写出代码的重要部分。
