8.2 注册测试环境账号并部署测试环境

• 使用邮箱注册测试环境账号，获取service_id和key。开发者可以自己实现接口请求或使用postman等工具来注册。下面提供apiary的api接口用于注册。调用接口时需根据实际情况计算sign和修改请求参数。

• 下载测试版迅雷链助手，新建个人测试用账户。使用第一步里的接口向对应的账户充值。

• 编译合约，获取部署合约所需的bytecode。这里如果使用truffle开发的话，可以使用truffle compile命令编译合约 /build 文件夹下获取对应合约的json文件，提取对应的bytecode。如果使用remix开发合约的话，点击 compile => Details 获取对应的bytecode。

• 如果合约的构造函数带有初始化参数，需要计算初始化参数params的data。如果使用remix开发合约的话，点击 run，选中要部署的合约，输入初始化参数，点击 deploy。在控制台中可以查看此交易的详细信息，其中的input即为合约编译的bytecode与初始化参数组成的data。由于测试环境的部署接口，将合约编译的bytecode与初始化参数的params分离开来，所以这里需要将params对应的data单独提取。如果使用的是ethers.js，利用ethers.utils.ABICoder的encode方法，编译对应的初始化参数为部署合约的params。

var ethers = require('ethers')
var abiCoder = new ethers.utils.AbiCoder()
return abiCoder.encode(['address'], ['0xca35b7d915458ef540ade6068dfe2f44e8fa733c'])
// 0x000000000000000000000000ca35b7d915458ef540ade6068dfe2f44e8fa733c

• 调用测试环境测试环境部署合约接口，参数为上述的bytecode、params以及部署合约的email和计算的签名sign。请求结果会返回一个部署合约的id。然后调用根据id查询合约地址接口，查询已部署合约的地址。
