如何使用curl从命令行界面（CLI）调用Mule的文件入站endpoint？

Question

我试图将多个文件从源移动/上传到目的地(可以是任何东西，例如FTP或文件出站等..)通过使用下面的流程

<flow name="flow1" doc:name="f1">
            <file:inbound-endpoint path="C:\input" responseTimeout="10000" doc:name="File"/>
    </flow>

<flow name="flow2" doc:name="f2">
  <http:inbound-endpoint address="http://localhost:8080" doc:name="HTTP" exchange-pattern="request-response"/>

  <flow-ref name="flow1" doc:name="Flow Reference"/>
        <file:outbound-endpoint path="C:\outputfile" responseTimeout="10000" doc:name="File"/>

</flow>

这样做的原因是我想使用CURL从CLI（命令行界面）调用作业。

但我收到以下错误：

错误：

请帮帮忙

Answer 1

文件endpoint是基于资源的endpoint(如ftp和s ftpendpoint)，而不是基于事件的endpoint(如jms和vm)或基于tcp的endpoint(如tcp、http、udp等)

因此，您正在实施的方法不适合您的用例。如果需要按需加载文件（即，当您命中 http endpoint时），则应重构流程并使用 mule 模块-文件-utils。此模块需要添加为专家依赖项或安装在 Studio 中。您可以通过克隆git存储库来执行此操作，然后您可以按照这些说明安装生成的更新站点zip文件

完成此操作后，您的流将如下所示：

        </foreach>

        </flow>
      </mule>

如果您不想使用fileutils模块，您可以将其替换为实现文件复制逻辑的脚本组件

现在可以使用下面的curl命令调用这个流

Curl超文本传输协议：//${主机名}： 8081/拷贝文件/${path_to_directory_to_copy}

试试这个

<flow name="flow1" doc:name="flow1" initialState="stopped">
  <file:inbound-endpoint path="C:\Input" responseTimeout="10000" doc:name="File"/>

  <file:outbound-endpoint path="C:\outputfile" responseTimeout="10000" doc:name="File"/>
</flow>

<flow name="flow2" doc:name="flow2">
  <http:inbound-endpoint address="http://localhost:8080/start" doc:name="HTTP" exchange-pattern="request-response"/>

  <expression-component>
    app.registry.filePickupFlow.start();
  </expression-component>

  <set-payload value="File successfully copied" />

</flow>
