1.DAPP实现Metamask自动添加网络/切换网络:
实现方法调用matamask的wallet_switchEthereumChain方法
async addNetwork() {
// console.log("当前链接的节点为:", getInjectedProviderName())
if (getInjectedProviderName() !== "MetaMask") {
throw "This Network is Error";
}
let chain_info = ChainInfo[ChainId];
try {
await this.web3.currentProvider.request({
method: 'wallet_switchEthereumChain',
params: [{
chainId: this.web3.utils.numberToHex(chain_info.chainId), }],
});
} catch (switchError: any) {
// This error code indicates that the chain has not been added to MetaMask.
if (switchError.code === 4902) {
await this.web3.currentProvider.request({
method: 'wallet_addEthereumChain',
params: [
{
chainId: this.web3.utils.numberToHex(chain_info.chainId),
chainName: chain_info.chainParams.chainName,
rpcUrls: chain_info.chainParams.rpcUrls,
blockExplorerUrls: chain_info.chainParams.blockExplorerUrls,
nativeCurrency: chain_info.chainParams.nativeCurrency
},
],
});
}
}
}
