问题复现

新建账号 bcskillsurou,并部署eosio.token合约,此账号创建代币EOS,并发行后

cleos set contract bcskillsurou /mnt/c/github/eos/build/contracts/eosio.token/ -p bcskillsurou
cleos push action bcskillsurou create '["eosio","1500000000.00000000 BSC",0,0,0]' -p bcskillsurou
cleos push action bcskillsurou issue '["eosio","150000000.00000000 BSC","issue"]' -p bcskillsurou

当使用cleos执行transfer时

cleos -u  https://www.bcskill.com transfer bcskillsurou xxxxxxxxxxxx "10 BSC"

提示

Error 3010014: Invalid symbol
Error Details:
Symbol BSC is not supported by token contract bcskillsurou

但使用push action

cleos -u https://dev-api-chain.valicn.com push action bcskillsurou transfer '["bcskillsurou", "xxxxxxxxxxxx","100000000.0000 BSC","vote"]' -p bcskillsurou

是发送正常的.说明问题判断条件不在合约.

查看cleos代码
问题代码所在(cleos/main.cpp)
因为cleos 执行transfer时会先执行rpc get_currency_stats_func,拿到代币的精度,然后补齐.但默认是从系统主代币token合约(eosio.token)获取,如果是自定义合约的话,需要单独参数(["--contract,-c"](https://github.com/EOSIO/eos/blob/448287d520f5f8c282139ecc60f227c218d42e82/programs/cleos/main.cpp#L3033 ""--contract,-c""))指定.
所以正确的transfer 命令为

cleos -u  https://www.bcskill.com transfer bcskillsurou xxxxxxxxxxxx "10 BSC" -c bcskillsurou
