内联脚本错误

Question

我试图使用内联脚本运行更新api，我的代码是

 client.prepareUpdate("result",typeName, "1")
       .setScript(new  Script("ctx._source.gender=doc['"+AggregateValue_First+"'].value*doc['"+AggregateValue_Second+"'].value",ScriptType.INLINE, null, null))
       .get();

当我执行它时，我得到

java.lang.IllegalArgumentException: failed to execute script

 Caused by: ScriptException[failed to run inline script
 [ctx._source.gender =
 doc['AVG_PRICE_PER_UNIT'].value*doc['NUMBER_OF_UNITS'].value] using

现在的错误类似于

Answer 1

尝试这样做（即使用ctx._source而不是doc):

client.prepareUpdate("result",typeName, "1")
   .setScript(new  Script("ctx._source.gender = ctx._source['"+AggregateValue_First+"'] * ctx._source['"+AggregateValue_Second+"']", ScriptType.INLINE, null, null))
   .get();
