Token名：CM DFA 符号名：DFA 小数位数：8
./cmc client contract user create --contract-name=cmdfa --version=1.0 --sync-result=true --sdk-conf-path=./testdata/sdk_config_solo.yml --byte-code-path=./testdata/cmdfa.7z --runtime-type=DOCKER_GO --admin-crt-file-paths=./testdata/crypto-config/wx-org.chainmaker.org/user/admin1/admin1.sign.crt --admin-key-file-paths=./testdata/crypto-config/wx-org.chainmaker.org/user/admin1/admin1.sign.key --params="{\"name\":\"CM DFA\", \"symbol\":\"DFA\", \"decimals\":\"8\"}"铸造Token
铸造10个Token，因为小数位数为8，所以参数的数量是：1000000000
./cmc client contract user invoke --contract-name=cmdfa --method=Mint --sync-result=true --sdk-conf-path=./testdata/sdk_config_solo.yml --params="{\"account\":\"自己的地址\", \"amount\":\"1000000000\"}"查询余额
./cmc client contract user get --contract-name=cmdfa --method=BalanceOf --sdk-conf-path=./testdata/sdk_config_solo.yml --params="{\"account\":\"自己的地址\"}"转账1个Token
转移1个Token，因为小数位数为8，所以参数的数量是：100000000
./cmc client contract user invoke --contract-name=cmdfa --method=Transfer --sync-result=true --sdk-conf-path=./testdata/sdk_config_solo.yml --params="{\"to\":\"UserB的地址\", \"amount\":\"100000000\"}"销毁1个Token
./cmc client contract user invoke --contract-name=cmdfa --method=Burn --sync-result=true --sdk-conf-path=./testdata/sdk_config_solo.yml --params="{\"amount\":\"100000000\"}"查询Token的名字
./cmc client contract user get --contract-name=cmdfa --method=Name --sdk-conf-path=./testdata/sdk_config_solo.yml --params="{}"查询Token的符号
./cmc client contract user get --contract-name=cmdfa --method=Symbol --sdk-conf-path=./testdata/sdk_config_solo.yml --params="{}"查询Token的小数位数
./cmc client contract user get --contract-name=cmdfa --method=Decimals --sdk-conf-path=./testdata/sdk_config_solo.yml --params="{}"查询Token的发行量
./cmc client contract user get --contract-name=cmdfa --method=TotalSupply --sdk-conf-path=./testdata/sdk_config_solo.yml --params="{}"授权转移操作
授权3个Token给用户C
./cmc client contract user invoke --contract-name=cmdfa --method=Approve --sync-result=true --sdk-conf-path=./testdata/sdk_config_solo.yml --params="{\"spender\":\"UserC的地址\", \"amount\":\"300000000\"}"C用户转移Token给用户B
因为是用的UserC的身份，所以需要切换SDK_Config到UserC的对应配置
./cmc client contract user invoke --contract-name=cmdfa --method=TransferFrom --sync-result=true --sdk-conf-path=./testdata/sdk_config_UserC.yml --params="{\"from\":\"UserA的地址\",\"to\":\"UserB的地址\", \"amount\":\"100000000\"}"查询用户A授权给用户C的转移额度
本来授权了3Token，现在转移了1个，所以结果应该2Token
./cmc client contract user get --contract-name=cmdfa --method=Allowance --sdk-conf-path=./testdata/sdk_config_UserC.yml --params="{\"spender\":\"UserC的地址\",\"owner\":\"UserA的地址\"}"UserC从授权账户UserA销毁1Token
因为是用的UserC的身份，所以需要切换SDK_Config到UserC的对应配置
./cmc client contract user invoke --contract-name=cmdfa --method=BurnFrom --sync-result=true --sdk-conf-path=./testdata/sdk_config_UserC.yml --params="{\"account\":\"UserA的地址\", \"amount\":\"100000000\"}"
