编译的方式有很多,既可以选择使用在线编译工具如remix编译,也可以选择使用true、wae等框架创建本地合约工程并编译.
下面简单介绍两种编译方式的使用过程:使用remix编译合约需要在remix右侧的pluginmanager里添加SolidityCompilerPlugin.
然后根据合约的需要选择合适的编译选项,比如solc的版本,EVM的版本以及优化选项等.
修改代码后点击Compile或者勾选自动编译选项,可以点击下面的CompilationDetails按钮查看编译详情,或者直接点击下面的Bytecode和ABI按钮复制对应的内容.
使用true编译合约1.
新建合约工程2.
添加合约文件Vote.
sol3.
修改编译选项true-cong.
js编译选项的修改主要是$npmi-gtruffle$mkdirvote-contract$cdvote-contract$truffleinit4.
执行编译truecompile5.
从build/Vote.

这里就需要用到前面启动的peer节点,以及节点内的账户来执行下面的操作.
从与peer节点的交互的方式上区分,可以从以下两种方式来执行部署合约和调用合约的流程:1.
通过peer启动的rpc端口attach到geth控制台执行2.
通过启动的wallet服务,发送请求到对应的接口来执行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[{"constant":false,"inputs":[{"internalType":"string","name":"_s","type":"string"}],"name":"setS","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"internalType":"uint256","name":"_t","type":"uint256"}],"name":"setT","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"inputs":[],"payable":false,"stateMutability":"nonpayable","type":"constructor"},{"constant":true,"inputs":[],"name":"owner","outputs":[{"internalType":"address","name":"","type":"address"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"s","outputs":[{"internalType":"string","name":"","type":"string"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"t","outputs":[{"internalType":"uint256","name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"}]通过peer节点的Geth控制台部署这里的节点以本地测试网络节点为例.

应用唤醒链克口袋应用方拼接交易并直接通过链接的形式唤醒链克口袋,传入交易参数.

编译的方式有很多,既可以选择使用在线编译工具如remix编译,也可以选择使用true、wae等框架创建本地合约工程并编译.
下面简单介绍两种编译方式的使用过程:使用remix编译合约需要在remix右侧的pluginmanager里添加SolidityCompilerPlugin.
然后根据合约的需要选择合适的编译选项,比如solc的版本,EVM的版本以及优化选项等.
修改代码后点击Compile或者勾选自动编译选项,可以点击下面的CompilationDetails按钮查看编译详情,或者直接点击下面的Bytecode和ABI按钮复制对应的内容.
使用true编译合约1.
新建合约工程2.
添加合约文件Vote.
sol3.
修改编译选项true-cong.
js编译选项的修改主要是$npmi-gtruffle$mkdirvote-contract$cdvote-contract$truffleinit4.
执行编译truecompile5.
从build/Vote.
json下复制所需的bytecode和abi部署合约与调用由上一步得到的bytecode和ABI如下(编译环境不同得到的值可能不同)compilers:{solc:{version:"0.

这里就需要用到前面启动的peer节点,以及节点内的账户来执行下面的操作.
从与peer节点的交互的方式上区分,可以从以下两种方式来执行部署合约和调用合约的流程:1.
通过peer启动的rpc端口attach到geth控制台执行2.
通过启动的wallet服务,发送请求到对应的接口来执行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[{"constant":false,"inputs":[{"internalType":"string","name":"_s","type":"string"}],"name":"setS","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"internalType":"uint256","name":"_t","type":"uint256"}],"name":"setT","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"inputs":[],"payable":false,"stateMutability":"nonpayable","type":"constructor"},{"constant":true,"inputs":[],"name":"owner","outputs":[{"internalType":"address","name":"","type":"address"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"s","outputs":[{"internalType":"string","name":"","type":"string"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"t","outputs":[{"internalType":"uint256","name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"}]通过peer节点的Geth控制台部署这里的节点以本地测试网络节点为例.
