基于Sepolia测试网的Node.js调用智能家居合约失败求助

核心问题分析 #

• 未实际执行合约方法：你只是引用了send方法/方法对象，没有触发实际调用
• 参数类型不匹配：addAppliance的bytes1参数需传入十六进制格式值，而非数字
• 缺少交易签名与异步处理：修改合约状态的方法需要签名交易，且所有合约调用都是异步操作

关键修复点说明 #

• 实际调用合约方法：修改状态的方法需执行.send()（或签名后发送），只读方法需执行.call()，不能仅引用方法对象
• 参数类型修正：bytes1类型参数必须传入十六进制字符串（如'0x01'），不能直接传数字
• 交易签名：Sepolia测试网要求修改合约状态的交易必须签名，使用web3.eth.accounts.signTransaction处理签名逻辑
• 异步处理：所有合约调用都是异步操作，用async/await处理结果，避免回调地狱
• 链ID与Gas配置：指定Sepolia的链ID（11155111），自动估算Gas并获取当前Gas价格，确保交易能成功上链
