-- 8. 修复聊天消息表 (ml_chat_messages) 的 RLS 策略
|
||
-- 解决 403 Forbidden 问题 (无法发送消息) 和无法获取聊天记录的问题
|
||
-- 说明：supabaseService 发送的是 auth.uid()，所以 sender_id/receiver_id 存储的是 Auth ID
|
||
-- =====================================================================================
|
||
|
||
-- 1. 确保表存在 (如果尚未创建)
|
||
CREATE TABLE IF NOT EXISTS public.ml_chat_messages (
|
||
id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
|
||
sender_id UUID NOT NULL, -- 发送方 Auth ID
|
||
receiver_id UUID NOT NULL, -- 接收方 Auth ID (或店铺关联ID)
|
||
content TEXT NOT NULL,
|
||
msg_type VARCHAR(20) DEFAULT 'text', -- text, image, etc
|
||
is_read BOOLEAN DEFAULT FALSE,
|
||
is_from_user BOOLEAN DEFAULT TRUE,
|
||
extra_data TEXT, -- 额外JSON数据
|
||
created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW(),
|
||
updated_at TIMESTAMP WITH TIME ZONE DEFAULT NOW()
|
||
);
|
||
|
||
-- 2. 开启 RLS
|
||
ALTER TABLE public.ml_chat_messages ENABLE ROW LEVEL SECURITY;
|
||
|
||
-- 3. 清理旧策略 (避免冲突)
|
||
DROP POLICY IF EXISTS "chat_messages_insert_policy" ON public.ml_chat_messages;
|
||
DROP POLICY IF EXISTS "chat_messages_select_policy" ON public.ml_chat_messages;
|
||
DROP POLICY IF EXISTS "chat_messages_update_policy" ON public.ml_chat_messages;
|
||
|
||
-- 4. 创建新策略
|
||
|
||
-- 策略：允许用户插入消息 (只要 sender_id 是自己)
|
||
CREATE POLICY "chat_messages_insert_policy" ON public.ml_chat_messages
|
||
FOR INSERT WITH CHECK (
|
||
auth.uid() = sender_id
|
||
);
|
||
|
||
-- 策略：允许用户查询消息 (只要自己是 sender_id 或 receiver_id)
|
||
-- 注意：如果 receiver_id 是店铺ID，商家查询时可能需要额外逻辑 (此处仅保证作为 User 能看到自己的收发)
|
||
CREATE POLICY "chat_messages_select_policy" ON public.ml_chat_messages
|
||
FOR SELECT USING (
|
||
auth.uid() = sender_id
|
||
OR
|
||
auth.uid() = receiver_id
|
||
);
|
||
|
||
-- 策略：允许用户更新消息 (仅限接收者标记已读)
|
||
CREATE POLICY "chat_messages_update_policy" ON public.ml_chat_messages
|
||
FOR UPDATE USING (
|
||
auth.uid() = receiver_id
|
||
)
|
||
WITH CHECK (
|
||
auth.uid() = receiver_id
|
||
);
|
||
|
||
-- =====================================================================================
|
||
-- 5. 补充索引
|
||
-- =====================================================================================
|
||
CREATE INDEX IF NOT EXISTS idx_chat_messages_sender ON public.ml_chat_messages(sender_id);
|
||
CREATE INDEX IF NOT EXISTS idx_chat_messages_receiver ON public.ml_chat_messages(receiver_id);
|
||
CREATE INDEX IF NOT EXISTS idx_chat_messages_created_at ON public.ml_chat_messages(created_at DESC);
