seed 쫙 뽑히는걸 확인 할수 있다.

python secp256k1-py 오류

Build software better, together

GitHub is where people build software. More than 36 million people use GitHub to discover, fork, and contribute to over 100 million projects.

github.com

apt-get install build-essential automake pkg-config libtool libffi-dev libgmp-dev

apt-get install python3.7-dev libmysqlclient-dev

 

명령어 두개만 추가 설치해주면 끝.

Oauth2 Django

Django 2019. 7. 11. 12:11

생각보다 개념이 없더라.

1] 사용자는 client_id 숫자와 redirect할 홈페이지를
get으로 서버에 날린다.

2] facebook서버는 일회용 token을 준다.

3] 사용자는 token과 일회용token과 secret_key를 함께 날린다.

1,2,3이 바바박 되면서 로그인이 된다.

client_id ,secret_key는 facebook서버에 가입해서 받는다.

django.db.utils.OperationalError: (1071, 'Specified key was too long; max key length is 767 bytes')

Django 2019. 7. 9. 17:06

django.db.utils.OperationalError: (1071, 'Specified key was too long; max key length is 767 bytes')

 

 

python3 manage.py migrate에서 에러뜨는 경우

아래 처럼 바꾸면 됩니다.

 

MariaDB [(none)]> ALTER DATABASE `데이터베이스명` CHARACTER SET utf8;
Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]> exit

 

재실행하면 끝
