Question

我正在尝试将 Composer JSON 文本插入到 MySQL 数据库的 TEXT 列中。

如果我插入以下内容

insert into server_details set composer = '"psr-4": {
                                                "App\\": "app/"
                                }'

插入数据库的是什么

"psr-4": { "App\": "app/" }

注意 App 后面只有一个反斜杠。如何在不使 JSON 无效的情况下将 Composer JSON 插入 sql 数据库？

被插入的完整 JSON 是：

禁用 NO_BACKSLASH_ESCAPES 模式会禁用黑色斜线。

如果启用NO_BACKSLASH_ESCAES模式，使用“App\/”；

包含两个反斜杠的 MySQL 文本
