在定位问题的时候，有时候需要找到导致问题出现的那个请求，比如下单。但是只有订单号，怎么去找呢？目前我们一般是根据下单时间，然后再根据时间去找对应的请求，但是请求很多，需要一个一个打开请求内容去定位该订单的下单请求。本文使用脚本的方式方便快速定位到对应的请求

根据时间和接口名称获取批量请求

获取批量请求

curl 'http://sky.fy.qq.com/graphql' \
  -H 'Content-Type: application/json;charset=UTF-8' \
  --data-raw '{"query":"query queryTraces($condition: TraceQueryCondition) {\n  traces: queryBasicTraces(condition: $condition) {\n    data: traces {\n      key: segmentId\n      endpointNames\n      duration\n      start\n      isError\n      traceIds\n    }\n    total\n  }}","variables":{"condition":{"queryDuration":{"start":"2021-10-22 1708","end":"2021-10-22 1723","step":"MINUTE"},"traceState":"ALL","paging":{"pageNum":1,"pageSize":15,"needTotal":true},"queryOrder":"BY_START_TIME","endpointName":"/userc/v1/user/address/addAddress"}}}' > sky_response.txt

从结果中提取traceId

jq '.data.traces.data[] | .traceIds[]' sky_response.txt  | sed 's/"//g' > sky_trace.txt

获取请求链路信息

获取单个请求的详细信息

curl -X POST 'http://sky.fy.qq.com/graphql' \
-H 'Content-Type: application/json' \
--data-raw '{
    "query": "query queryTrace($traceId: ID\u0021) {trace: queryTrace(traceId: $traceId) {spans {traceId tags {key value}}}}",
    "variables": {
        "traceId": "04557c8a528142bbaf0f996ac1250484.508.16348946392203935"
    }
}' > one_trace.txt
