This article is about how MySQL solves the problem of being unable to store emoji emoticons. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

The details are as follows

1. In navicat

If you change the coding of the database before creating a new table, it seems that you can change it yourself when you build the table.

View character set encodings:

Show variables like'% char%'

Change the database code:

ALTER DATABASE database name CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci

Change the table encoding:

ALTER TABLE table name CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci

The following seems to be useless, but you can also use them if you can't.

Set @ @ character_set_client='utf8mb4';set @ @ character_set_connection='utf8mb4';set @ @ character_set_results='utf8mb4';set @ @ character_set_server='utf8mb4'

two。 In crawler code

Class MysqlPipeline (object): def _ init__ (self): self.conn = MySQLdb.connect ('127.0.0.1,' root', 'root',' article_spider', charset='utf8mb4', use_unicode=True) self.cursor = self.conn.cursor () def process_item (self, item, spider): insert_sql =''insert into article (title,url,bookmark_nums,url_object_id,content) VALUE (% s% s % title'% s)''self.cursor.execute (insert_sql, (item [' title'], item ['url'], item [' bookmark_nums'], item ['url_object_id'], item [' content'])) self.conn.commit () Thank you for reading!
