EOS小白学习之番外（二）合约执行的常见错误

本篇记录一些常见的错误及其处理，大饼果子非C++出身，如有错误，欢迎指出

1. 合约执行错误

$ cleos push action eosio.token transfer '["eosio", "dabingguozi", "2.0000 SYS" ,"contract"]' 

Error 3040003: Transaction should have at least one required authority

这是因为合约要求用户授权，合约代码如下

所以要执行以下命令

$ cleos push action eosio.token transfer '["eosio", "dabingguozi", "2.0000 SYS" ,"contract"]' -p eosio

 就成功啦

2. account name不能够创建

$ cleos system newaccount eosio dabingguozi EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV --stake-net "1000 SYS" --stake-cpu "1000 SYS" --buy-ram-kbytes 8 -p eosio

Error 3050001: Account name already exists

因为account name是唯一的，出现这种情况没有办法，只能换一个名字啦
