Question

我需要通过HTTP POST传输XML文件。可以配置Mule来执行此操作。我一直在尝试一个简单的流量，入站文件 - ＆gt;超出HTTP，但它不起作用。有没有人有这方面的经验？

    <flow name="rpg_uploadFlow1" doc:name="rpg_uploadFlow1">
    <file:inbound-endpoint path="C:\Users\Claes\Documents\CD-utveckling\paper-rpg\OUT" moveToDirectory="C:\Users\Claes\Documents\CD-utveckling\paper-rpg\sent" responseTimeout="10000" mimeType="text/xml" doc:name="File"/>
    <http:outbound-endpoint exchange-pattern="one-way" host="http://XXXXXXXXXXX.ashx?SystemName=XXXX&amp;UserName=XXXX&amp;PassWord=XXXXX" port="80" disableTransportTransformer="true" doc:name="HTTP"/>

</flow>

错误;

Answer 1

我在文件端点的某些位置遇到了麻烦，因为它传递了文件读取器作为有效负载而不是实际文本。尝试添加文件到字符串转换器：

<flow name="rpg_uploadFlow1" doc:name="rpg_uploadFlow1">
    <file:inbound-endpoint path="C:\Users\Claes\Documents\CD-utveckling\paper-rpg\OUT" moveToDirectory="C:\Users\Claes\Documents\CD-utveckling\paper-rpg\sent" responseTimeout="10000" mimeType="text/xml" doc:name="File"/>
    <file:file-to-string-transformer doc:name="File to String"/>
    <http:outbound-endpoint exchange-pattern="one-way" host="http://XXXXXXXXXXX.ashx?SystemName=XXXX&amp;UserName=XXXX&amp;PassWord=XXXXX" port="80" disableTransportTransformer="true" doc:name="HTTP"/>
</flow>

Answer 2

你可以使用一个mule字节数组来串起变换器，使你的请求成为字符串，然后将其发布到你的http出站。

<flow name="rpg_uploadFlow1" doc:name="rpg_uploadFlow1">
    <file:inbound-endpoint path="C:\Users\Claes\Documents\CD-utveckling\paper-rpg\OUT" moveToDirectory="C:\Users\Claes\Documents\CD-utveckling\paper-rpg\sent" responseTimeout="10000" mimeType="text/xml" doc:name="File"/>

    <byte-array-to-string-transformer></byte-array-to-string-transformer>
  .....

出现错误。我猜它与骡子标签和端点无关。这是访问您正在尝试的网址的东西。

请参阅以下帖子，了解与UnknownHostException相关的问题。

java.net.UnknownHostException when accessing a URL

Answer 3

试试这个：您可以使用一个mule字节数组来串起变换器，将您请求的File作为字符串，然后使用SetPayload或Attachment Connector并将其发布到您的http出站。

MULE可以通过HTTP从本地目录发布XML文件吗？
