cleos get table name,无法精准定位

2020-04-08　 Surou　阅读　 EOS-新手问答　 0 评论

当get table索引是name 时，无法精准查询
因为cleos 传入的参数默认是字符串，需要对应的转换参数
--key-type name

例如

cleos -u https://api.eosnewyork.io:443 get table eosio eosio voters --key-type name -L 111111111122 -l 1

参考

执行命令查看输出log

关键错误

TCP/IP, --shared-memory, or --named-pipe should be configured on NT OS

解决方案

修改my.ini,添加shared-memory

2059 – 身份验证插件’caching_sha2_password’-navicat连接异常

2020-04-02　 Surou　阅读　 Other-经验分享　 0 评论

这个问题是由于我的MySQL的的的更新至8版本以上了，在安装的时候我并没有指定用户登入密码加密方式，所以默认被设置为caching_sha2_password
解决方法：

mysql> show variables like 'default_authentication_plugin';

Variable_name	Value
default_authentication_plugin	caching_sha2_password

查看本地mysql用户的信息

mysql> select host,user,plugin from mysql.user;

host	user	plugin
localhost	mysql.infoschema	caching_sha2_password
localhost	mysql.session	caching_sha2_password
localhost	mysql.sys	caching_sha2_password
localhost	root	caching_sha2_password

注意 caching_sha2_password，只修改root的密码加密方式就可以了

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';

mysql> select host,user,plugin from mysql.user;

host	user	plugin
localhost	mysql.infoschema	caching_sha2_password
localhost	mysql.session	caching_sha2_password
localhost	mysql.sys	caching_sha2_password
localhost	root	mysql_native_password

使用tdm-gcc
https://jmeubank.github.io/tdm-gcc/download/
然后再系统环境变量path里把tdragon的位置上移到cygwin上面，
让系统调用gcc时先识别tdragon的gcc，或者直接把cygwin的环境路径直接删除了，
或者直接从goland里的settings->Go->GoPath里添加tdragon的路径，如下图
