EOS DApp integrate with Scatter

This is a very simple Demo project to show that how to sign a EOS transaction with Scatter.

github地址

基于EOS的Dapp就是html页面通过调用eosjs与EOS链进行RPC通信，进行合约执行与数据交换。

下面演示Hello合约的Dapp调用
合约源代码
//hello.cpp

#include <eosiolib/eosio.hpp>
using namespace eosio;

class hello : public eosio::contract {
  public:
      using contract::contract;

      /// @abi action 
      void hi( account_name user ) {
         print( "Hello, ", name{user} );
      }
};

EOSIO_ABI( hello, (hi) )

合约部署参考（零基础部署测试合约（三）---合约部署）

html 调用js关键代码

import EOS from 'eosjs'
const EOS_CONFIG = {
  contractName: "dapp.token", // Contract name
  contractReceiver: "dapp.exec", // User executing the contract (should be paired with private key)
  clientConfig: {
    keyProvider: '5JC9FdRjX3c3fsB62S5Tz22LgTuRHegb1XEV16uft8u3njmm9E5', // Your private key
    httpEndpoint: 'http://192.168.1.112:8888', // EOS http endpoint
    chainId: '706a7ddd808de9fc2b8879904f3b392256c83104c1d544b38302cc07d9fca477'
  }
}
//执行合约
DoContract(){
let eosClient = EOS(EOS_CONFIG.clientConfig)
    eosClient.contract(EOS_CONFIG.contractName)
      .then((contract) => {
        contract.hi(EOS_CONFIG.contractReceiver, { authorization: [EOS_CONFIG.contractReceiver] })
          .then((res) => { console.log("Success") })
          .catch((err) => {console.log("Fail"); console.log(err) })
      })
}
