如何使用Mule通过REST通过HTTP上传多个文件? [英] How to upload multiple files via REST over HTTP using Mule?

问题描述

我有一个文件夹"MyFiles"，其中有很多文件.现在，我需要通过REST over HTTP上传那些文件.该怎么办?

I have a folder say "MyFiles" where I have lots of files. Now I need to upload those file via REST over HTTP . What will be the approach?

我尝试了以下操作，但这是错误的

I tried the below but it is wrong

<flow name="testFlow1" doc:name="testFlow1">
        <http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8081" doc:name="HTTP"/>


         <http:rest-service-component 
                                serviceUrl="http://localhost:8280/rest/xyz" 
                                httpMethod="POST"> 
         </http:rest-service-component> 

    <http:endpoint host="localhost" port="5430" encoding="UTF-8" 
                method="POST" connector-ref="fileHttp" path="fileuploader" name="muleFileUploader">
       </http:endpoint>

</flow>

请帮助.由于输入文件夹将包含多个文件，我们又如何实现呢?

Please help. Since the input folder will have multiple files, how can we achieve that also?

谢谢

推荐答案

您的流不使用文件入站终结点，而是使用通用(非进出)HTTP终结点，因此无法正常工作.

Your flow doesn't use a file inbound endpoint and uses a generic (non-in non-out) HTTP endpoint so there's no way this can work.

以下是成功将文件上传到HTTP端点的配置.没有object-to-byte-array-transformer，我无法使其正常工作(同一文件一遍又一遍地被轮询-错误吗?)，所以希望您的文件不会太大...

Below is a configuration that successfully uploads files to an HTTP endpoint. I can not make it work without the object-to-byte-array-transformer (the same file gets polled over and over again - bug?), so I hope your files are not huge...

<flow name="fileUploader">
    <file:inbound-endpoint path="/tmp/mule/in"
        pollingFrequency="5000" moveToDirectory="/tmp/mule/done" />
    <object-to-byte-array-transformer />
    <http:outbound-endpoint address="http://..."
        method="POST" exchange-pattern="request-response" />
</flow>
