我的代理服务从Gmail IMAP服务器接收电子邮件。电子邮件也包含csv文件附件。 WSO2 ESB成功收到了电子邮件，但在日志中，附件内容打印为 base64 编码的字符串。以下是我的axis2.xml connfigs。

WSO2 ESB中是否有任何方法可以保存目录中的附件？任何帮助都会很有帮助。

Answer 1

您可以通过注册＆＃34; org.apache.axis2.format.PlainTextBuilder＆＃34;来访问csv的请求/响应有效负载内的内容。和＆＃34; org.apache.axis2.format.PlainTextFormatter＆＃34;作为text / csv content-type的消息构建器和格式化程序。

请将以下格式化程序和构建器添加到axis2.xml。请检查建设者。

<messageformatter contenttype="text/csv" class="org.apache.axis2.format.PlainTextFormatter"/>

<messagebuilder contenttype="text/csv" class="org.apache.axis2.format.PlainTextBuilder"/>

为什么WSO2 ESB在Base64中编码电子邮件附件
