问题描述

我需要通过WSO2 EI 6.5.0将pdf / png / jpeg文件发送到电子邮件中

我有一个代理人

<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
       name="EmailService"
       startOnLoad="true"
       statistics="disable"
       trace="disable"
       transports="http,https">
   <target>
      <inSequence>
         <log level="custom">
            <property name="[EmailService] Initialize" value="SendMailSequence"/>
         </log>
         <property name="Subject" scope="transport" value="WSO2 EI Testing"/>
         <property name="transport.mail.bodyWhenAttached"
                   scope="axis2"
                   value="This text will appear in body"/>
         <property name="enableMTOM" scope="axis2" type="STRING" value="true"/>
         <log level="custom">
            <property expression="/" name="[EmailService] Before Send"/>
         </log>
         <property name="FORCE_SC_ACCEPTED" scope="axis2" value="true"/>
         <property name="OUT_ONLY" value="true"/>
         <property name="messageType"
                   scope="axis2"
                   type="STRING"
                   value="multipart/form-data"/>
         <send>
            <endpoint name="FileEpr">
               <address optimize="mtom" uri="mailtoOwn:listopadov_as@kk.bank"/>
            </endpoint>
         </send>
      </inSequence>
      <outSequence/>
   </target>
   <description/>
</proxy>

我正在尝试使用fiddler发送文件（取款支票）：

POST http://localhost:8280/services/EmailService HTTP/1.1
Content-Type: multipart/form-data; boundary=NewBoundary

--NewBoundary
Content-disposition: form-data; name="attachment"; filename="cheque.png"
Content-Type: image/png

<...binary data...>
--NewBoundary--

我在WSO2 EI 6.5.0控制台中得到了这个

结果是我得到了cheque.png文件，但由于内部数据是base64编码的，因此它已损坏，即使我手动对其进行解码并将解码后的数据插入文件中，该文件仍然损坏，因此我无法可以查看它。

我尝试了其他几个选项，并尝试将base64Decode放入有效负载中：

<payloadFactory media-type="xml">
            <format>
               <root>
                  <file filename="cheque.png">$1</file>
               </root>
            </format>
            <args>
               <arg evaluator="xml" expression="base64Decode(//*[local-name()='attachment']/text())"/>
            </args>
         </payloadFactory>

但是仍然没有帮助。

在WSO2 EI 6.5.0中如何通过电子邮件发送文件的工作示例请帮助我

设置了我的axis2 messageBuilders，并且取消了MailTransportSender的注释并且可以正常工作。
