NFT 元数据 JSON：集合字段错误

Question

我无法让我铸造的 NFT 显示在我创建的收藏中。我在 ERC1155 合约上运行，所以我无法通过构造函数创建集合。因此，我提到 ChatGPT 使用字段数组“集合”。它似乎完全无法识别，因为其余 NFT 内容显示但不在任何集合（Unspecified Contract）下。请参考下面的代码，了解我在 JSON 中可能遇到的任何错误，或者如果需要在其中创建合同/连接到在 Opensea 中制作的收集合同地址，请参考合同。我特别需要 ERC1155 格式，因为我需要为同一成就 NFT 显示多个数量。感谢您的阅读。

这是一个重复的问题。原始问题/解决方案可在以下位置找到：How to fix "Unidentified contract"? OpenSea 无法“理解”ERC1155

为了快速回答这篇文章，Opensea 期望在 ERC-1155 合约上有 2 个公开声明的变量“name”和“symbol”。只需设置这些变量即可。
