#### 3.1 Core Multi-Channel Infrastructure

Package: jcifs.internal.smb2.multichannel
├── ChannelManager.java           - Manage multiple channels per session

        // When
        transformHeader.setFlags(flags);

        // Then
        assertEquals(flags, transformHeader.getFlags());
    }

    @Test
    @DisplayName("Should set and get session ID")
    void testSessionId() {
        // When
        transformHeader.setSessionId(testSessionId);

        // Then
        assertEquals(testSessionId, transformHeader.getSessionId());
    }

OpenAPI 中定義的安全模式，包括：

* HTTP 基本認證。
* **OAuth2**（也使用 **JWT tokens**）。在 [OAuth2 with JWT](tutorial/security/oauth2-jwt.md) 查看教學。
* API 密鑰，在：
    * 標頭（Header）
    * 查詢參數
    * Cookies，等等。

加上來自 Starlette（包括 **session cookie**）的所有安全特性。

所有的這些都是可重複使用的工具和套件，可以輕鬆與你的系統、資料儲存（Data Stores）、關聯式資料庫（RDBMS）以及非關聯式資料庫（NoSQL）等等整合。

### 依賴注入（Dependency Injection） { #dependency-injection }

	coupon := &Coupon{
		AppliesToProduct: []*CouponProduct{
			{ProductId: "full-save-association-product1"},
		},
		AmountOff:  10,
		PercentOff: 0.0,
	}

	err := DB.
		Session(&gorm.Session{FullSaveAssociations: true}).
		Create(coupon).Error
	if err != nil {
		t.Errorf("Failed, got error: %v", err)
	}

	if DB.First(&Coupon{}, "id = ?", coupon.ID).Error != nil {

	if err := DB.First(&User{}, "name = ?", "transaction").Error; err == nil {
		t.Fatalf("Should not find record after rollback, but got %v", err)
	}

	txDB := DB.Where("fake_name = ?", "fake_name")
	tx2 := txDB.Session(&gorm.Session{NewDB: true}).Begin()
	user2 := *GetUser("transaction-2", Config{})
	if err := tx2.Save(&user2).Error; err != nil {
		t.Fatalf("No error should raise, but got %v", err)
	}

* API keys in:
    * Headers.
    * Query parameters.
    * Cookies, etc.

Plus all the security features from Starlette (including **session cookies**).

All built as reusable tools and components that are easy to integrate with your systems, data stores, relational and NoSQL databases, etc.
