功能介绍

该接口用于查询指定日志流下的日志内容。

调用方法

请参见如何调用API

URI

POST /v2/{project_id}/groups/{log_group_id}/streams/{log_stream_id}/content/query

表1 路径参数

参数

是否必选

参数类型

描述

project_id

String

项目ID,获取方式请参见:获取项目ID,获取账号ID,日志组ID、日志流ID

最小长度:32

最大长度:32

log_group_id

String

日志组ID,获取方式请参见:获取项目ID,获取账号ID,日志组ID、日志流ID

最小长度:36

最大长度:36

log_stream_id

String

日志流ID,获取方式请参见:获取项目ID,获取账号ID,日志组ID、日志流ID

最小长度:36

最大长度:36

请求参数

表2 请求Header参数

参数

是否必选

参数类型

描述

X-Auth-Token

String

从IAM服务获取的用户Token,获取方式请参见:获取用户Token

最小长度:1000

最大长度:2000

Content-Type

String

该字段填为:application/json;charset=UTF-8。

最小长度:30

最大长度:30

表3 请求Body参数

参数

是否必选

参数类型

描述

start_time

String

搜索起始时间(UTC时间,毫秒级)。

说明:

查询时间最大为180天。

end_time

String

搜索结束时间(UTC时间,毫秒级)。

说明:

查询时间最大为180天。

labels

Map<String,String>

日志过滤条件集合,不同日志来源所需字段不同。

keywords

String

支持关键词精确搜索。关键词指相邻两个分词符之间的单词,例:error

line_num

String

日志单行序列号,第一次查询时不需要此参数,后续分页查询时需要使用,可从上次查询的返回信息中获取。line_num应在start_time 和end_time之间。 若已开启自定义时间功能,在使用该字段的同时,还需要增加__time__字段共同进行分页查询。

最小长度:19

最大长度:19

__time__

String

若已开启自定义时间功能,需要使用该字段和line_num字段共同进行分页查询,参数可从上次查询的返回信息中获取。

is_desc

Boolean

顺序或者倒序查询, 默认为false(顺序查询)

枚举值:

  • false

search_type

String

首次查询为 “init”, 分页查询时为 “forwards”或者“backwards”, 默认为首次查询“init”, 与 is_desc 参数配合进行分页查询。

枚举值:

  • forwards

limit

Integer

表示每次查询的日志条数,不填时默认为50,建议您设置为100。

最小值:1

最大值:5000

highlight

Boolean

日志关键词高亮显示,默认为true(高亮显示),false为取消高亮显示。

缺省值:true

is_count

Boolean

日志条数统计。默认为false(不统计),true为统计日志条数。

is_iterative

Boolean

日志迭代查询,默认为false(不开启迭代),true为开启迭代。

query

String

使用带管道符的sql分析语句进行查询,需要query参数is_analysis_query为true时生效。

is_analysis_query

Boolean

是否为带管道符的sql分析语句。当该参数为true时,将依照body体中的query参数内容进行查询,且body体中除start_time与end_time以外的参数失效,分页、排序、查询结果条数等功能请依照sql语法规则实现。查询结果的响应体不同于未启用时的查询方式,将以默认列存的形式返回查询结果。当前仅对内测用户开放。响应示例:{"analysisLogs":[{"field1":"1","field2":"2","field3":"3"},{"field1":"1","field2":"2","field3":"3"},{"field1":"1","field2":"2","field3":"3"}]} (管道符为邀测功能,非白名单用户默认为false)

响应参数
