如何连接确定我在 Ganache 中连接的网络
我试过这个 const networkId = await Web3.eth.net.getId()
但我得到的错误是这个
未处理的拒绝(TypeError):无法读取未定义的属性“网络”
由于您使用的是Web3with capital W,我假设它是类的名称 - 而不是实例。
Web3
W
您需要访问实例属性net及其方法getId()。
net
getId()
// instantiate the class first const web3 = new Web3(); // mind the lowercase `w` in `web3`, accessing the instance const networkId = await web3.eth.net.getId();
