有效JSON上的JSON解析失败

Question

下面是我的logstash.conf文件：

input {
    http {
        host => "127.0.0.1"
        port => 31311 
        ssl => false
    }
}

filter {
    mutate {
        split => { "[headers][request_path]" => "/"}
        add_field => { "index_id" => "%{[headers][request_path][1]}" }
    }

    ruby { 
        code => "event.set('request_path_length', event.get('[headers][request_path]').length)" 
    }

    if [request_path_length] == 3 {
        mutate {
            add_field => { "document_id" => "%{[headers][request_path][2]}" }
        }
    }
}

output {
    stdout {
        codec => "json"
    }

    if [request_path_length] == 3 {
        elasticsearch {
            hosts => "http://localhost:9200"
            index => "%{index_id}"
            document_id => "%{document_id}"
        }
    }
    else {
        elasticsearch {
            hosts => "http://localhost:9200"
            index => "%{index_id}"
        }
    }
}

更新：

我运行了一个稍微不同的命令：

PS c:\users\me\downloads\curl-7.64.1-win64-mingw\bin>.\curl.exe-h“content-type：application/json”-xput'http://127.0.0.1:31311/bo ok/1'-d'{\“indexid\”:\“book\”，\“documentid\”:\“0\”，\“title\”:\“ekqxaqqszaaukvhxab\”，\“edition\”:\“1\”，\“作者\”：{\“name\”:\“mark Twai n\”，\“国籍\”：“:\”哈珀·柯林斯\“，\”总部地址\“：{\”国家\“:\”丹麦\“，\”街名\“:\”krqaqiktutmtz\“，\”邮政编码\“:\”4539\“，\”州\“:\”woosesvgwijdzsz\“}}}‘

这一次，我在LogStash终端中看到了这个错误消息：

[2019-04-10T12:53:03,799][ERROR][logstash.codecs.json     ] JSON parse error, original data now in message field {:error=>#<LogStash::Json::ParserError: Unexpected end-of-input: was expecting closing quote for a string value

Answer 1

尝试使用：

{\"IndexId\":\"Book\",\"DocumentId\":\"0\",\"Title\":\"EKQXAQQSZAAUKVLKVHXAB\",\"Edition\":\"1\",\"Author\":{\"Name\":\"Mark Twai n\",\"Nationality\":\"France\"},\"Publisher\":{\"Name\":\"Harper Collins\",\"HeadquartersAddress\":{\"Country\":\"Denmark\",\"StreetName\":\"KRQAQIKTUTMTZ\",\"PostalCode\":\"4539\",\"State\":\"WOOSESVGWIJDZSZ\"}}}

注意France之前的双引号没有转义，并且在第一个双引号之前的StreetName值中有一个错误的空格。
