google CloudSQL mysql 表情符号（1366，"Incorrect string value: '\xF0\x9F\x98\x80\xF0\x9F...' for column 'name' at row 1"）

Question

当我使用 my-app.appspot.com 时，我无法将 post 表情符号发送到数据库但是当我运行在本地 python manage.py runserver 使用 GAE 上的相同库时，一切都完美无缺，我可以 post 并检索表情符号。

这是我的设置.py

import os
if os.getenv('SERVER_SOFTWARE', '').startswith('Google App Engine'):
    # Running on production App Engine, so use a Google Cloud SQL database.
    DATABASES = {
        'default': {
            'ENGINE': 'django.db.backends.mysql',
            'HOST': '/cloudsql/my-app:us-central1:my-app-mysql',
            'NAME': '********',
            'USER': 'root',
            'PASSWORD': '*********',
        }
    }
else:
    DATABASES = {
        'default': {
            'ENGINE': 'django.db.backends.mysql',
            'NAME': '*******',
            'USER': 'root',
            'PASSWORD': '*********',
            'HOST': '**********',
            'PORT': '3306',
            'OPTIONS': {
                 'charset': 'utf8mb4',
            }
        }
    }

这里是使用云时的字符集shell

mysql> SHOW VARIABLES WHERE Variable_name LIKE 'character\_set\_%' OR Variable_name LIKE 'collation%';
+--------------------------+--------------------+
| Variable_name            | Value              |
+--------------------------+--------------------+
| character_set_client     | utf8               |
| character_set_connection | utf8               |
| character_set_database   | utf8mb4            |
| character_set_filesystem | binary             |
| character_set_results    | utf8               |
| character_set_server     | utf8mb4            |
| character_set_system     | utf8               |
| collation_connection     | utf8_general_ci    |
| collation_database       | utf8mb4_general_ci |
| collation_server         | utf8mb4_general_ci |
+--------------------------+--------------------+
10 rows in set (0.15 sec)

这是我从另一个客户端使用数据库的 IP 连接时的字符集

Variable_name                        Value
character_set_client                utf8
character_set_connection            utf8mb4
character_set_database              utf8mb4
character_set_filesystem            binary
character_set_results               utf8
character_set_server                utf8mb4
character_set_system                utf8
collation_connection                utf8mb4_unicode_ci
collation_database                  utf8mb4_general_ci
collation_server                    utf8mb4_general_ci

我是不是漏了什么？！！

我如何工作？

waprin: @EssaAlshammri reproduced, filed internal bug with engineering team, will keep you updated.

来自 github issue

You can try base64 encoding going in and out of the database as a workaround.

它工作正常。

你可以等到他们解决问题
