Question

我正在尝试使用脚本介体编辑有效负载，但是它给出了这个错误：

TID: [0] [ESB] [2014-02-26 11:55:31,709] ERROR {org.apache.axis2.transport.base.threads.NativeWorkerPool} -  Uncaught exception {org.apache.axis2.transport.base.threads.NativeWorkerPool}

代码：

<script language="js" key="conf:SecHeaderGenerator.js" function="getBodyWithSecHeader" />

javascript文件：

function getBodyWithSecHeader(mc)
{
  var body = mc.getPayloadXML();

  var time = new Date().format("yyyy-MM-dd'T'HH:mm:ss+0300");
  var user = 'user';
  var domain = 'testdomain';
  var password = 'pass';
  var encoded = hex_md5(time + hex_md5(password)).toLowerCase();

  mc.setPayloadXML(
    <set_message_status>
      <user>
        <now>{time}</now>
        <login>{user}</login>
        <company>{domain}</company>
        <auth_string>{encoded}</auth_string>
      </user>
      {body}
    </set_message_status>);

    return mc.getPayloadXML();
}
[...]

为什么会出现此错误？我正在使用WSO2 ESB 4.6.0。

更新

使用相同版本的另一个ESB副本尝试完全相同的场景，它可以正常工作。

我找到了解决方案。问题是javascript文件的媒体类型是text/plain而不是application/javascript。

脚本调解器给出'ContentID为空'错误
