SIMPLE DELETE 示例

SIMPLE DELETE 示例

此示例使用的源文件包含以下数据： 
2
1
下图显示了已选中“参数化基础 URL”选项的 SIMPLE DELETE 示例的 HTTP 转换的 HTTP 选项卡：
“编辑转换”对话框中的“HTTP”选项卡包含名称、数据类型、精度、小数位数、输入和输出列。该选项卡还包含“转换名称”、“HTTP 方法”、“默认值”、“说明”、“HTTP 名称”、“基础 URL”和“最终 URL”字段。选中“参数化基础 URL”复选框。
选中“参数化基础 URL”复选框时，Designer 会将输入组输入端口名称附加到基础 URL 来构建最终 URL： 
http://www.avengers5:8181/emp_all/$id/
集成服务将源文件值发送至 HTTP 转换的 id 输入端口，并将以下 HTTP 请求发送至 HTTP 服务器： 
http://www.avengers5:8181/emp_all/2
http://www.avengers5:8181/emp_all/1
SIMPLE DELETE 方法会从 HTTP 服务器中删除所需数据。HTTP 服务器将 HTTP 响应发回集成服务，然后集成服务通过 HTTP 转换的输出端口将更新后的数据发送至目标。
