Question

我需要在Mule 4中将管道分隔文本文件转换为JSON。我尝试使用以下代码。

`<file:listener doc:name="Fetch Input from Geometry SFTP" doc:id="1151a602-6748-43b7-b491-2caedf6f7010" directory="C:\Vijay\My Projects\AM-Mexico\US\AIM-65\Input" autoDelete="true" outputMimeType="text/csv; separator=|" recursive="false">
            <non-repeatable-stream />
            <scheduling-strategy >
                <fixed-frequency frequency="10" timeUnit="SECONDS"/>
            </scheduling-strategy>
        </file:listener>
        <ee:transform doc:name="Transform Message" doc:id="79dcddf9-34a0-4005-88b4-3a395544be8c" >
            <ee:message >
                <ee:set-payload ><![CDATA[%dw 2.0
output application/json
input payload text/csv
---
payload]]></ee:set-payload>
            </ee:message>
        </ee:transform>`

如果我尝试执行代码，则会出现如下异常。

对此将提供任何帮助。

您需要为separator设置阅读器属性：

%dw 2.0
input payload application/csv separator='|'
output application/json
---
payload
