本章我们实现领取委托奖励, 赎回委托以及实现多网络节点功能.
编写显示钱包委托列表页面
在component目录下创建my-delegate-table.vue文件, 如下图
部分代码如下:
<template>
<div class="my-delegate-table">
<div class="horzontal-layout header-bar flex-horzontal-center ">
<span class="flex-1"></span>
<span>总委托</span>
<span style="margin:0 16px;">{{ totalDelegate }}LAT</span>
<span>可领取</span>
<span style="margin:0 16px;">{{ totalReward }}LAT</span>
<el-button type="primary" size="mini" round style="margin:0 16px 0 0;">领取</el-button>
</div>
<el-table :data="datas" style="width: 100%" height="400">
<el-table-column prop="nodeName" label="节点名" width="120"> </el-table-column>
<el-table-column prop="nodeId" label="节点ID" width="500">
<template slot-scope="scope">
<span class="ellipsis">{{ scope.row.nodeId }}</span>
</template>
</el-table-column>
<el-table-column prop="deletegateLAT" label="委托LAT"> </el-table-column>
<el-table-column prop="reward" label="待领取奖励" />
<el-table-column label="操作" header-align="center" align="center" fixed="right">
<template slot-scope="scope">
<el-button size="mini" type="text" @click="onUnDelegate(scope.row)"
>赎回委托</el-button
>
</template>
</el-table-column>
</el-table>
</div>
</template>
然后再main-page.vue页面使用该组件, 效果如下图:
编写获取委托列表的逻辑
在background.js页面的委托管理类, 添加如下代码:
/**
* 获取所有节点委托信息
* @returns
*/
static async GetDelegateInfoList() ;
/**
* 获取单个节点的委托情况
* @param {*} ppos
* @param {*} hexStrBufAddr
* @param {*} nodeStrBufId
* @param {*} delegateNode
* @returns
*/
static async getSingleDelegateInfo(ppos, hexStrBufAddr, nodeStrBufId, delegateNode) ;
/**
* 获取节点信息
* @param {} ppos
* @param {*} nodeId
*/
static async getNodeInfo(ppos, nodeStrBufId) ;
/**
* 获取所有节点未领取的奖励
* @param {*} ppos
* @param {*} hexStrBufAddr
* @param {*} delegateNodeList
*/
static async getRewardMap(ppos, hexStrBufAddr);
/**
* 查询当前账户地址所委托的节点的NodeID和质押Id
* @param {*} address
*/
static async getRelatedListByDelAddr(ppos, hexStrBufAddr);
由于节点并没提供直接获取所有委托信息的接口, 因此我们需要通过调用几个接口才能获取.其流程如下:
- 先调用1103这个接口获取钱包地址所有委托的节点预计委托的时的块高信息, 该接口返回以下信息:
Addr: 委托人的账户地址
NodeId: 委托的节点 Id
StakingBlockNum: 发起质押时的区块高度 - 接着调用5100接口,获取当前地址,所有节点Id的委托奖励情况, 该接口返回一下信息:
reward: 未领取的委托收益
nodeID: 委托的节点 Id
stakingNum: 发起质押时的区块高度
这里需要注意的是, reward返回的类型是16进制的,需要调用web3.utils.hexToNumberString转成10进制的字符串. - 接着通过1105接口,获取节点名.该接口返回的字段很多, 但是我们只用到界面名NodeName这个字段
- 最后调用1104获取,在该节点上委托的LAT数量, 委托的数量包括自由LAT Released字段和锁仓LAT RestrictingPlan字段,总的质押LAT数量需要把这两个相加.
最后我们可以看到,我们上一章委托10LAT的获得的奖励情况,如下图:
浏览器上的奖励如下图:
可以看到, 我们编写的逻辑获取到的奖励和区块链浏览器是一致的.
编写领取委托奖励的页面
在page目录下新建文件withdraw-delegate-reward-page.vue, 部分代码如下:
<template>
<div class="withdraw-delegate-reward-page vertical-only-layout">
<header-bar />
<div class="go-back" @click="onGoBack">< Back</div>
<page-title>领取委托奖励</page-title>
<el-form ref="sendForm" :model="withdrawInfo">
<el-form-item label="领取奖励">
<el-input class="send-input" disabled v-model="withdrawInfo.withdrawNum" />
</el-form-item>
<el-form-item label="所需手续费">
<el-input disabled class="send-input" v-model="withdrawInfo.gasfee" />
</el-form-item>
<el-form-item>
<div class="horzontal-layout">
<span class="flex-1"></span>
<el-button class="create-btn" @click="onGoBack">取消</el-button>
<el-button class="create-btn" type="primary" @click="onWithdraw"
>领取</el-button
>
</div>
</el-form-item>
</el-form>
</div>
</template>
页面效果如下图:
编写领取委托奖励的逻辑
在background.js文件中的委托管理类DelegateManager添加领取奖励的代码:
static async WithdrawDelegateReward() {
let web3 = NetworkManager.GetWebIns();
let curAccount = await PrivateKeyManager.GetCurrentAccount();
let privateketRes = await PrivateKeyManager.ExportPrivateKey(
curAccount,
PasswordManager.GetPassPassword()
);
if (privateketRes.errCode !== 0) {
return privateketRes;
}
let walletInfo = privateketRes.data;
let ppos = new web3.PPOS({ provider: NetworkManager.GetCurNetworkRPCUrl() });
ppos.updateSetting({
privateKey: walletInfo.privateKey,
chainId: NetworkManager.GetChainId()
});
let params = {
funcType: 5000 // 领取委托的函数
};
let reply = await ppos.send(params);
return {
errCode: SUCCESS
};
}
领取奖励后的截图如下:
可以看到奖励已经被领取.
切换到我们的交易记录页面, 可以看到领取奖励的记录:
编写赎回委托页面
在page目录下创建 undelegate-lat-page.vue文件, 部分代码如下:
<template>
<div class="delegate-lat-page vertical-only-layout">
<header-bar />
<div class="go-back" @click="onGoBack">< Back</div>
<page-title>赎回委托</page-title>
<el-form ref="delegateForm" :model="unDelegateInfo">
<el-form-item prop="nodeName" label="节点名">
<el-input disabled class="send-input" v-model="unDelegateInfo.nodeName" />
</el-form-item>
<el-form-item prop="nodeId" label="节点id">
<el-input disabled class="send-input" v-model="unDelegateInfo.nodeId" />
</el-form-item>
<el-form-item prop="lat" label="委托数量">
<el-input class="send-input" disabled v-model="unDelegateInfo.deletegateLAT" />
</el-form-item>
<el-form-item
prop="lat"
label="赎回数量"
:rules="[
{
required: true,
message: '请输入要委托的LAT数量(不少于10LAT)',
validator: ValidateLAT
}
]"
>
<el-input
class="send-input"
type="number"
v-model="unDelegateInfo.withdrawLat"
placeholder="请输入要赎回的LAT数量"
/>
</el-form-item>
<el-form-item label="所需手续费">
<el-input disabled class="send-input" v-model="unDelegateInfo.gasfee" />
</el-form-item>
<el-form-item>
<div class="horzontal-layout">
<span class="flex-1"></span>
<el-button class="create-btn" @click="onGoBack">取消</el-button>
<el-button class="create-btn" type="primary" @click="onUnDelegate"
>赎回</el-button
>
</div>
</el-form-item>
</el-form>
</div>
</template>
注意:赎回最小的LAT数量为10
界面效果如下:
编写赎回逻辑
在background.js的委托管理类DelegateManager添加以下代码:
/**
* 赎回委托
* @param {}} stakingBlockNum
* @param {*} nodeId
* @param {*} lat
* @returns
*/
static async UnDeletgate(stakingBlockNum, nodeId, lat) {
debugger
let web3 = NetworkManager.GetWebIns();
let curAccount = await PrivateKeyManager.GetCurrentAccount();
let privateketRes = await PrivateKeyManager.ExportPrivateKey(
curAccount,
PasswordManager.GetPassPassword()
);
if (privateketRes.errCode !== 0) {
return privateketRes;
}
let walletInfo = privateketRes.data;
let ppos = new web3.PPOS({ provider: NetworkManager.GetCurNetworkRPCUrl() });
ppos.updateSetting({
privateKey: walletInfo.privateKey,
chainId: NetworkManager.GetChainId()
});
debugger
stakingBlockNum = parseInt(stakingBlockNum);
let params = {
funcType: 1005, // 委托LAT的函数
stakingBlockNum: stakingBlockNum,
nodeId: ppos.hexStrBuf(nodeId),
amount: ppos.bigNumBuf(web3.utils.toVon(lat, "lat"))
};
let reply = await ppos.send(params);
return reply;
}
赎回的接入如下图:
以上就是LAT领取委托奖励和赎回委托的功能啦, 接着我们实现添加多网络.
编写添加网络节点页面
在page目录下新建文件add-networks-page.vue, 部分代码如下:
<template>
<div class="add-networks-page vertical-only-layout">
<header-bar />
<div class="go-back" @click="onGoBack">< Back</div>
<page-title>添加网络</page-title>
<el-form ref="networkForm" :model="networkInfo">
<el-form-item prop="name" label="网络名">
<el-input
class="send-input"
v-model="networkInfo.name"
:rules="[
{
required: true,
message: '请输入网络名'
}
]"
/>
</el-form-item>
<el-form-item prop="rpcUrl" label="新增RPC URL">
<el-input
class="send-input"
v-model="networkInfo.rpcUrl"
:rules="[
{
required: true,
message: '请输入RPC URL'
}
]"
/>
</el-form-item>
<el-form-item prop="chainId" label="ChainId">
<el-input
class="send-input"
v-model="networkInfo.chainId"
:rules="[
{
required: true,
message: '请输入chainId'
}
]"
/>
</el-form-item>
<el-form-item prop="browserUrl" label="浏览器地址">
<el-input
class="send-input"
v-model="networkInfo.browserUrl"
:rules="[
{
required: true,
message: '浏览器地址'
}
]"
/>
</el-form-item>
<el-form-item>
<div class="horzontal-layout">
<span class="flex-1"></span>
<el-button class="create-btn" @click="onGoBack">取消</el-button>
<el-button class="create-btn" type="primary" @click="onAdd">添加</el-button>
</div>
</el-form-item>
</el-form>
</div>
</template>
页面效果如下:
接着我们在main-page.vue页面增加跳转, 代码如下:
...省略代码
<el-dropdown trigger="click">
<div class="network-component horzontal-layout flex-center">
<span style="background:#e91550" class="circle-dot"></span>
<span class="network-name">{{ curNetworkName }}</span>
<i class="el-icon-arrow-down"></i>
</div>
<el-dropdown-menu slot="dropdown">
<el-dropdown-item
@click.native="onSwitchNetwork(item)"
v-for="(item, index) in networkList"
:key="index"
>{{ item }}</el-dropdown-item
>
<div class="line"></div>
<el-dropdown-item @click.native="onAddNetwork">添加网络</el-dropdown-item>
</el-dropdown-menu>
</el-dropdown>
...省略代码
效果如下图:
编写添加网络节点逻辑
在manifest.json文件中添加以下配置, 若不添加会出现跨域限制问题,具体作用,我们下一章讲导出Api的时在解释:
"content_scripts": [
{
"matches": [
"file://*/*",
"http://*/*",
"https://*/*"
],
"js": [
"js/contentscript.js"
],
"run_at": "document_start",
"all_frames": true
}
],
在background.js中的网络管理类NetworkManager,添加以代码:
/**
* 添加网络
* @param {*} netWorkInfo
* @returns
*/
static AddNetwork(netWorkInfo) {
return new Promise(resolve => {
// 判断网络是否已经存在
if (NetworkManager.networkInfos[netWorkInfo.name]) {
resolve({
errCode: ERROR,
errMsg: "网络已经存在!"
});
return;
}
NetworkManager.networkInfos[netWorkInfo.name] = {
rpcUrl: netWorkInfo.rpcUrl,
chainId: netWorkInfo.chainId,
browserUrl: netWorkInfo.browserUrl
};
chrome.storage.local.set(
{
networkInfos: NetworkManager.networkInfos
},
() => {
resolve({ errCode: SUCCESS });
}
);
});
}
笔者在本地部署了测试网和主网的节点如下图:
进程30004为测试网节点,31303位主网节点.
添加测试网节点:
这里笔者没有搭建自己的区块链浏览器, 使用的还是官网提供的.
效果如下图:
添加主节点效果如下图:
好啦,本章就到此结束啦.同时浏览器版的Digging所有核心功能已经完成了. 下一章,我们讲解如何把Digging的接口导出给网页使用.
