工作流2：生成报告#

在此工作流程中，您将合并来自不同来源的数据、转换二进制数据、生成文件并发送相关通知。最终的工作流程应如下所示：

*Workflow 2 for aggregating data and generating files*

为了简化操作，我们将工作流分为三个部分。

第一部分：从不同来源获取数据#

工作流的第一部分包含五个节点：

*Workflow 1: Getting data from different sources*

使用HTTP Request节点从存储公司数据的API端点获取数据。配置以下节点参数：
- 方法: 获取
- URL: 您报名本课程时在邮件中收到的数据集URL。
- Authentication: Generic Credential Type
  - 通用认证类型: Header Auth
  - Header Auth认证凭据: 您在注册本课程时通过邮件收到的Header Auth名称和Header Auth值。
- Send Headers: Toggle to true
  - 指定请求头: 选择 Using Fields Below
  - 名称: unique_id
  - 值: 您在注册本课程时收到的电子邮件中的唯一ID。
使用 Airtable节点 从 customers 表中列出数据（您已更新了 region 和 subregion 字段）。
使用Merge节点根据customerID字段匹配，合并来自Airtable和HTTP Request节点的数据。
使用Sort节点按orderPrice降序排列数据。

测验问题

分配给客户1的员工叫什么名字？
客户2的订单状态是什么？
最高订单价格是多少？

第二部分：生成区域销售文件#

工作流的第二部分包含四个节点：

*Workflow 2: Generating file for regional sales*

使用If节点进行筛选，仅显示来自Americas地区的订单。
使用Convert to File功能将传入的JSON数据转换为二进制格式。将每个项目转换为单独的文件。（如果能根据orderID为每个报告命名，可以获得额外加分！）
使用Gmail节点（或其他电子邮件节点）通过电子邮件将文件发送到您可访问的地址。请注意，您需要添加一个包含数据属性的附件。
Use the Discord节点 to send a message in the n8n Discord channel #course-level-two. In the node, configure the following parameters:
- Webhook URL: 注册本课程时在邮件中收到的Discord网址。
- 文本: "我通过电子邮件发送了带有标签ID {label ID}的文件。我的ID: " 后面跟着你注册本课程时通过邮件收到的唯一ID。
  注意你需要用表达式替换花括号{}中的文本，这些表达式引用来自节点的数据。

测验问题

有多少订单分配给了Americas地区？
Americas 地区的订单总价是多少？
Write Binary File节点会返回多少项数据？

第三部分：生成总销售额文件#

工作流的第三部分包含五个节点：

*Workflow 3: Generating files for total sales*

使用Loop Over Items节点将Item Lists节点的数据拆分成每批5个。
使用Set节点设置四个值，这些值通过前一个节点的表达式引用：customerEmail、customerRegion、customerSince和orderPrice。
Use the 日期与时间节点 to change the date format of the field customerSince to the format MM/DD/YYYY.
- 将包含输入字段选项设置为保持所有数据在一起。
使用Convert to File节点创建一个CSV电子表格，文件名设置为表达式：{{$runIndex > 0 ? 'file_low_orders':'file_high_orders'}}。
Use the Discord节点 to send a message in the n8n Discord channel #course-level-two. In the node, configure the following parameters:
- Webhook URL: 您在注册本课程时通过邮件收到的Discord网址。
- 文本: "我创建了电子表格 {file name}。我的ID："后面跟着您注册本课程时通过邮件收到的唯一ID。
  注意您需要将 {file name} 替换为引用前一个转换为文件节点数据的表达式。

测验问题

第一批商品中的最低订单价格是多少？
客户7的格式化日期是什么？
Convert to File节点会返回多少项数据？
