當我們登入自己的應用（可能也有自己的前端）時，這是合適的。

因為我們可以信任它接收 `username` 與 `password`，因為我們掌控它。

但如果你要打造一個讓他人連接的 OAuth2 應用（也就是你要建立一個相當於 Facebook、Google、GitHub 等的身分驗證提供者），你應該使用其他流程之一。

最常見的是 Implicit Flow（隱式流程）。

最安全的是 Authorization Code Flow（授權碼流程），但它需要更多步驟、實作也更複雜。因為較複雜，許多提供者最後會建議使用隱式流程。

/// note

很常見的是，每個身分驗證提供者會用不同的方式命名他們的流程，讓它成為品牌的一部分。

但最終，他們實作的都是相同的 OAuth2 標準。

                    .desc("Produce execution verbose output")

Prefer either:
  * Provide only non-nullable version and move the `null` check to the call site (if the number of nullable callsites is low).
  * Provide two overloads with a different names (as Java doesn't support overloading on nullability). See

Default config includes most common highly compressible content extensions and mime-types.

```bash
~ mc admin config set myminio compression extensions=".pdf" mime_types="application/pdf"
```

To show help on setting compression config values.

```bash
~ mc admin config set myminio compression
```

To enable compression for all content, no matter the extension and content type

typedef struct TF_AbstractOp TF_AbstractOp;

// Stores a function representation that can be used for execution or for
// setting functional attributes of other composite ops e.g. control flow.
typedef struct TF_AbstractFunction TF_AbstractFunction;

// This allows the client to swap the implementation of the tracing engine.
// Any future call to TF_CreateFunction will use the implementation defined
// here.

    full_name = user_dict["full_name"],
    hashed_password = hashed_password,
)
```

/// warning

The supporting additional functions `fake_password_hasher` and `fake_save_user` are just to demo a possible flow of the data, but they of course are not providing any real security.
