"Script" 1 : 1" 在 mule 4 中评估表达式错误

Question

我正在尝试使用肥皂信封、标题和正文设置有效负载。

然后通过 payload.indexOf("?>")+2 子串有效载荷

基于以下表达式：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns0="http://decisionresearch.com/RateMaker">
<soapenv:Header/>
<soapenv:Body>
#[payload.substring(payload.indexOf("?>")+2)]
</soapenv:Body>
</soapenv:Envelope> 

输入请求：https://github.com/Manikandan99/Map_request/blob/main/Request_map.xml

预期输出：https://github.com/Manikandan99/Map_request/blob/main/Response_map.xml

骡流：

<flow name="map_requestFlow" doc:id="21d0d652-3766-47ed-95aa-a451f62c5776" >
        <http:listener doc:name="Listener" doc:id="7312114b-2857-40b3-98cd-f52b628b3a28" config-ref="HTTP_Listener_config" path="/map"/>

&#10;&lt;soapenv:Body&gt;

&#10;&lt;/soapenv:Envelope&gt;]' doc:name="Set Payload" doc:id="faf2bc3b-e7a3-4708-910b-daeb05bb5f6e" />

如何用当前的payload封装soap？

Answer 1

这是错误的，原因有很多。首先，您不能在表达式中使用表达式。其次，您尝试使用字符串生成 XML，而 DataWeave 已经生成了有效的 XML。直接使用字符串非常容易出错。每当您看到生成或解析 XML 的字符串操作时，您都应该质疑其中的原因。

而是使用 DataWeave 在简单的转换中完全生成 XML：

%dw 2.0
output application/xml
ns soapenv http://schemas.xmlsoap.org/soap/envelope/
---
{
    soapenv#Envelop: {
        soapenv#Header: null,
        soapenv#Body: payload
    }
}

输出（假设输入的格式为 application/xml）：

<?xml version='1.0' encoding='UTF-8'?>
<soapenv:Envelop xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
  <soapenv:Header/>
  <soapenv:Body>
