我正在尝试在Elasticsearch中创建管道。 在确定要使用的管道之前,我必须进行检查,因此我已经建立了一个进行路由的管道,如下所示:
{
"description": "A pipeline of pipelines for log files",
"version": 1,
"processors": [
{
"pipeline": {
"if": """ctx.applicative_code =~ /AFA[@]959[@]333-SERVICE[@]1.0.0.SIG/ """,
"name": "ged_pipeline"
}
},
{
"fail": {
"message": "This pipeline requires applicative_code to be one of: 'AFA@959@333-SERVICE@1.0.0.SIG'"
}
}
]
}
要测试它,我使用_simulate API:
POST _ingest/pipeline/logs_pipeline/_simulate
{
"docs": [
{
"_source": {
"message_log": "127.0.0.1:50613||Download||agent||S0000||PM000||Q||{5C7A4600-C422-4D81-BD02-39072E06F646}",
"applicative_code": "AFA@959@333-SERVICE@1.0.0.SIG"
}
}
]
}
响应是这样的:
"error" : {
"root_cause" : [
{
"type" : "exception",
"reason" : "java.lang.IllegalArgumentException: org.elasticsearch.ingest.common.FailProcessorException: This pipeline requires applicative_code to be one of: 'AFA@959@333-SERVICE@1.0.0.SIG'",
"header" : {
"processor_type" : "fail"
}
}
],
"type" : "exception",
"reason" : "java.lang.IllegalArgumentException: org.elasticsearch.ingest.common.FailProcessorException: This pipeline requires applicative_code to be one of: 'AFA@959@333-SERVICE@1.0.0.SIG'",
"caused_by" : {
"type" : "illegal_argument_exception",
"reason" : "org.elasticsearch.ingest.common.FailProcessorException: This pipeline requires applicative_code to be one of: 'AFA@959@333-SERVICE@1.0.0.SIG'",
"caused_by" : {
"type" : "fail_processor_exception",
"reason" : "This pipeline requires applicative_code to be one of: 'AFA@959@333-SERVICE@1.0.0.SIG'"
}
所以,看来我的情况不符合要求。 我在这里使用正则表达式的原因是特殊字符“ @”弄乱了字符串比较。到目前为止,我在管道的if条件下尝试过的事情:
"if": """ctx.applicative_code == "AFA@959@333-SERVICE@1.0.0.SIG" """
结果:不起作用,@被解释,我无法使用\
对其进行转义"if": """ctx.applicative_code.compareTo("AFA@959@333-SERVICE@1.0.0.SIG") """
结果:一样,@被解释
有什么想法吗?
答案 0 :(得分:0)
嗯,您快到了,但是您误解了管道的工作方式。第一个pipeline
处理器已匹配并完成了工作,这一事实并不能阻止第二个fail
运行。在上面的管道中,两个步骤始终都在运行,因此为什么会看到错误。
您需要做的是仅在条件不匹配(某种fail
条件)的情况下运行else
步骤,
