映射未映射的存储桶后，InfluxDB v2兼容性端点/查询不起作用

问题描述

在Grafana中为InfluxDB 2.0（2.0.0-beta.16）创建InfluxQL数据源失败，并显示以下错误：

can't assign to property "executedQueryString" on "<!doctype html><html><head><Meta charset=\"utf-8\"><Meta name=\"viewport\" content=\"width=device-width,initial-scale=1\"><title>InfluxDB 2.0</title><base href=\"/\"><link rel=\"shortcut icon\" href=\"/favicon.ico\"></head><body><div id=\"react-root\" data-basepath=\"\"></div><script src=\"/5e93c5f5aa.js\"></script></body></html>": not an object

我按照以下过程在https://docs.influxdata.com/influxdb/v2.0/query-data/influxql/#map-unmapped-buckets上映射未映射的存储桶，并尝试使用https://docs.influxdata.com/influxdb/v2.0/tools/grafana/#configure-grafana-to-use-influxql在Grafana中创建数据源

使用邮递员，在查询与InfluxDB v1兼容的端点时得到的输出相同：

curl --location --request GET 'http://54.226.129.163/query?db=db-35days&rp=rp-35days' \
--header 'Authorization: Token VuLd01YvgyBNnWQlzFXDgDT08DFGdfgr4et6456HzrNpHqKF4q8VvQUZrmlLoyUUpJbdSU0mwUPYISV1LdjQ==' \
--data-urlencode 'q=select * from ping'

我已验证数据库保留策略映射是否可用：

curl --location --request GET 'http://my-influxdb/api/v2/dbrps/06868db0219ad000?org=PBC' \
--header 'Authorization: Token VuLd01YvgyBNnWQlzFXDgDT08DFGdfgr4et6456HzrNpHqKF4q8VvQUZrmlLoyUUpJbdSU0mwUPYISV1LdjQ=='


{
    "content": {
        "id": "06868db0219ad000","database": "db-35days","retention_policy": "rp-35days","default": true,"organization_id": "218adfcaf421474d","bucket_id": "9fd165c106e5f962"
    }
}

根据https://docs.influxdata.com/influxdb/v2.0/reference/api/influxdb-1x/dbrp/上的文档，将使用DBRP映射自动创建新的数据库/保留策略存储桶，如果找不到匹配的存储桶，则将数据写入存储桶。我也使用“所有访问令牌”进行了尝试，但是得到了相同的错误响应：

curl --location --request POST 'http://my-influxdb/write?db=testdb&rp=testrp' \
--header 'Content-Type: application/json' \
--header 'Authorization: Token VuLd01YvgyBNnWQlzFXDgDT08DFGdfgr4et6456HzrNpHqKF4q8VvQUZrmlLoyUUpJbdSU0mwUPYISV1LdjQ==' \
--data-raw 'measurement,host=host1 field1=2i,field2=2.0 1577836800000000000'

我可以使用Flux查询v2终结点：

curl --location --request POST 'http://my-influxdb/api/v2/query?org=PBC' \
--header 'Content-Type: application/vnd.flux' \
--header 'Accept: application/csv' \
--header 'Authorization: Token VuLd01YvgyBNnWQlzFXDgDT08DFGdfgr4et6456HzrNpHqKF4q8VvQUZrmlLoyUUpJbdSU0mwUPYISV1LdjQ==' \
--data-raw 'from(bucket: "35days")
  |> range(start: -12h)
  |> filter(fn: (r) => r["_measurement"] == "ping")
  |> yield(name: "mean")',result,table,_start,_stop,_time,_value,_field,_measurement,account,mean,2020-10-27T22:52:58.644679856Z,2020-10-28T10:52:58.644679856Z,2020-10-28T08:49:35Z,0.4,standard_deviation_ms,ping,pbc

解决方法

使用InfluxDB v2 GA版本解决了该问题。

在InfluxDB 2.0.2中仍然对我来说是问题我可以在日志中看到它根本无法读取我的查询：

curl --request GET http://localhost:8086/query \
> --header "Authorization: Token <token>" \
> --data-urlencode "db=<db>" \
> --data-urlencode "rp=autogen" \
> --data-urlencode "q=SELECT * FROM <measurment>"

在映射之后。这是我在日志中看到的内容
