契约URI未获取-在元问询中显示“无标题集合”

Question

我已经创建了一个ERC1155智能合同，它在opensea上非常好地工作-它发现uri和contractURI很好。但是，当我在testnet上添加NFT以询问元数据时，虽然NFT数据是准确的，但收集的数据似乎没有被获取。它将NFT放置在“无标题集合”选项卡中。

以下是智能契约功能：

    function contractURI() public view returns (string memory) {
return theContractUri;
}

下面是如何格式化联系人URI：

    {   

"collection" :{

    "name": "Farmverse Farmers",
    "image": "ipfs://bafkreic57ucjp6yrfjg4jt7x2533vm4vismg5gxm4phy4wkhbqlzydfvde/"

},
"collectible" :{

    "name": "Farmverse Farmers",
    "image": "ipfs://bafkreic57ucjp6yrfjg4jt7x2533vm4vismg5gxm4phy4wkhbqlzydfvde/"

},
"contract" :{

    "name": "Farmverse Farmers",
    "image": "ipfs://bafkreic57ucjp6yrfjg4jt7x2533vm4vismg5gxm4phy4wkhbqlzydfvde/"

},
    "name": "Farmverse Farmers",
    "description": "“The Farmers” is an NFT collection that contains 5555 unique, computer-generated little characters.  Besides being collectibles these tokens are also your key to unlocking the wonders of Farmverse – a multiplayer play-to-earn online video game.",
    "image": "ipfs://bafkreic57ucjp6yrfjg4jt7x2533vm4vismg5gxm4phy4wkhbqlzydfvde/",
    "external_link": "https://farm-verse.com"
}

所以我不明白，元问题从哪里获取集合名称？在shuld中，我把它放在我的contractURI或常规tokenURI中，以便集合名和图像在元问询手机中显示出来。

提前感谢！

我想出来了。

看看在合同代码中可以做些什么：

string public name;
string public symbol;
event UpdateNameEvent(string oldName, string newName);
event UpdateSymbolEvent(string oldSymbol, string newSymbol);

constructor( string memory _name, string memory _symbol ) ERC1155('anything can be done here'){
    name = _name;
    symbol = _symbol;
}

如果您想稍后进行更新，您可以使用代码进行更新。

function updateName(string memory newName) external onlyOwner{
    string memory oldName = name;
    name = newName;
    emit UpdateNameEvent(oldName, name);
}

function updateSymbol(string memory newSymbol) external onlyOwner{
    string memory oldSymbol = symbol;
    symbol = newSymbol;
    emit UpdateSymbolEvent(oldSymbol, symbol);
}
