Marklogic 8 rest扩展插件多部分/表单数据存在文件上载问题

我在ML8中编写了一个小的rest扩展，它基本上存储上传到ml内容数据库中的文件。。当我这样做时，我得到以下异常

<error-response xmlns="http://marklogic.com/xdmp/error">
<status-code>500</status-code>
<status>Internal Server Error</status>
<message-code>INTERNAL ERROR</message-code>
<message>XDMP-UPDATEFUNCTIONFROMQUERY: xdmp:function(fn:QName("http://marklogic.com/rest-api/resource/repoLoad","post"), "/marklogic.rest.resource/repoLoad/assets/resource.xqy")($context, $service-params, $input) -- Cannot apply an update function from a query . See the MarkLogic server error log for further detail.</message>
</error-response>

下面是日志文件中的错误跟踪

默认情况下，MarkLogic REST扩展在特定的更新模式下运行，具体取决于请求方法和单/多语句。自MarkLogic 8以来，POST方法单个语句的默认更新模式更改为

query

。向

repoLoad:post

方法添加注释，如下所示：

declare %rapi:transaction-mode("update") function repoLoad:post(...)
