求一个DAPP规则说明

dapp规则分为两类

1. dapp获取app数据：通过挂载自己的方法到全局，接收app发来的数据

1. app获取dapp数据：通过设置导航来给app数据

以上便是dapp规则的使用方法，具体原理请看这篇

1. The version number of the app requested by the front end

js://GetAppVersion

2. App returns the current version

javascript:window.sendAppVersion(‘ version : Int’)

3. Front End Request for Local Wallet List  

js://GetAllWallet  

4. app call returns wallet data to front end, jsonArray = [{name:name, address:wallet address, pubkeyhash:public key hash}]

javascript:window.getAppHtmlPukey('jsonArray.toString()' )

5.Called after the front end selects the wallet, returning the selected wallet address,data =the selected wallet address

js://ChooseWalletCallback?data=xxx

6. Transaction processing: Front-end call, data is unsigned transaction, called after successful broadcast of transaction signature  

js://setTransaction?data=xxx

7. Return Data to Front End

javascript:window.getAppTransResult( 'json')json = {code = 0, data= null,msg = ""}  

code=0 Indicate success

data = {

transactionHash: "transaction hash",

blockHash:"block hash",

blockHeight:"block height",

fee:"Service Charge"

}

8.Refresh Page Function, App-side Call

javascript:window.initGetMatrix()

1、前端请求App的版本号；js://GetAppVersion 

2、App 回传 当前版本；javascript:window.sendAppVersion(‘ version : Int’) 

3、前端请求获取本地钱包列表；js://GetAllWallet

 4、App 调用回传钱包数据给前端；jsonArray = [{name: 名字, address: 钱包地址, pubkeyhash: 公钥hash}]javascript:window.getAppHtmlPukey('jsonArray.toString()' )

 5、前面选择钱包后调用,回传选择钱包地址  data为选择的钱包地址；js://ChooseWalletCallback?data=xxx 

6、事务处理: 前端调用, data为未签名的事务；js://setTransaction?data=xxx 

7、事务签名广播成功后调用，回传数据给前端；javascript:window.getAppTransResult( 'json')json = {code = 0, data= null,msg = ""}  code=0 表示成功data = {

transactionHash: "事务hash",

blockHash:"区块hash",

blockHeight:"区块高度",

fee:"手续费"

}

 8、刷新页面函数,App端调用。javascript:window.initGetMatrix()
