对painless脚本调试
- 数据准备
- 测试代码
1、数据准备
PUT /hockey/_doc/1?refresh
{"first":"johnny","last":"gaudreau","goals":[9,27,1],"assists":[17,46,0],"gp":[26,82,1]}2、测试
测试一
POST /hockey/_explain/1
{
"query": {
"script": {
"script": "Debug.explain(doc.goals)"
}
}
}
执行结果：
{
"error": {
"root_cause": [
{
"type": "painless_explain_error",
"reason": "painless_explain_error: null"
}
],
"type": "script_exception",
"reason": "runtime error",
"painless_class": "org.elasticsearch.index.fielddata.ScriptDocValues.Longs",
"to_string": "[1, 9, 27]",

}测试二
POST /hockey/_update/1
{
"script": "Debug.explain(ctx._source)"
}
测试结果：
