## Why distributed MinIO?

      setException(t);
      return;
    } finally {
      function = null;
    }

    /*
     * If set()/setValue() throws an Error, we let it propagate. Why? The most likely Error is a
     * StackOverflowError (from deep transform(..., directExecutor()) nesting), and calling
     * setException(stackOverflowError) would fail:
     *

If you have a different use case that needs to exit early from a dependency with `yield`, please create a [GitHub Discussion Question](https://github.com/fastapi/fastapi/discussions/new?category=questions) with your specific use case and why you would benefit from having early closing for dependencies with `yield`.

If there are compelling use cases for early closing in dependencies with `yield`, I would consider adding a new way to opt in to early closing.

If the PR meets the above conditions, you can merge it. 😎

## Review PRs

* If a PR doesn't explain what it does or why, if it seems like it could be useful, ask for more information. Otherwise, feel free to close it.

But that means that if you just convert it to a string and return that information directly, you could be leaking a bit of information about your system, that's why here the code extracts and shows each error independently.

### Use the `RequestValidationError` body { #use-the-requestvalidationerror-body }

如果密碼不匹配，我們回傳同樣的錯誤。

#### 密碼雜湊（hashing） { #password-hashing }

「雜湊」的意思是：把一些內容（這裡是密碼）轉換成一串看起來像亂碼的位元組序列（就是字串）。

只要你輸入完全相同的內容（完全相同的密碼），就會得到完全相同的亂碼。

但你無法從這串亂碼還原回原本的密碼。

##### 為何要做密碼雜湊 { #why-use-password-hashing }

如果你的資料庫被竊取，攻擊者拿到的不是使用者的純文字密碼，而只是雜湊值。

因此攻擊者無法嘗試把那些密碼用在其他系統上（因為很多使用者在各處都用同一組密碼，這會很危險）。

如果密码不匹配，则返回与上面相同的错误。

#### 密码哈希 { #password-hashing }

**哈希**是指，将指定内容（本例中为密码）转换为形似乱码的字节序列（其实就是字符串）。

每次传入完全相同的内容（比如，完全相同的密码）时，得到的都是完全相同的乱码。

但这个乱码无法转换回传入的密码。

##### 为什么使用密码哈希 { #why-use-password-hashing }

原因很简单，假如数据库被盗，窃贼无法获取用户的明文密码，得到的只是哈希值。

这样一来，窃贼就无法在其它应用中使用窃取的密码，要知道，很多用户在所有系统中都使用相同的密码，风险超大。
