Question

我有一个带vfs传输的WSO2ESB 4.7代理。我需要读一些像这样的xml文件：

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE Header PUBLIC "/usr/xxx.dtd" "/usr/xxx.dtd">
<Header xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
...

代理：

<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse" name="test" statistics="disable" trace="disable" transports="vfs">
    <parameter name="transport.PollInterval">5</parameter>
    <parameter name="transport.vfs.FileURI">C:\WSO2</parameter>
    <parameter name="transport.vfs.FileNamePattern">.*[.][xX][mM][lL]$</parameter>
    <parameter name="transport.vfs.ContentType">application/xml</parameter>
    <target>
        <inSequence>
            <property name="OUT_ONLY" value="true"/>
            <log level="full"/>
            <send>
                <endpoint>
                    ...
                </endpoint>
            </send>
        </inSequence>
    </target>
</proxy>

Wso2返回此错误：

是否有可能让wso2忽略Doctype？

我不想将文件读取为text / plain，删除doctype，转换为xml，使用它，转换为text / plain，添加doctype。

Answer 1

将以下参数添加到代理服务。然后它将允许DOCTYPE声明

<parameter name="ApplicationXMLBuilder.allowDTD">true</parameter>

wso2 esb transport vfs，使用Doctype读取xml文件失败
