将 FIWARE Orion 与 Azure Cosmos DB 连接

Question

我尝试使用 FIWARE Orion [1]，对于数据库，我使用 Azure Cosmos DB Mongo API。我按照问题 [2] 中概述的步骤进行操作。 docker-compose.yml文件内容为：

 version: "3" 

 services:
   orion:
     image: fiware/orion
     ports:
       - "1026:1026"
     command: -dbhost "mongo-perf-testing.mongo.cosmos.azure.com:10255" -db "fiver_db" -dbuser "mongo-perf-testing" -dbpwd "password" -dbSSL -dbDisableRetryWrites -logLevel DEBUG -t 100

当我运行 docker 容器时，它启动正常。

然后我运行以下查询：

查询：curl localhost:1026/version 回应：

{
"orion" : {
  "version" : "3.6.0",
  "uptime" : "0 d, 0 h, 9 m, 31 s",
  "git_hash" : "973850279e63d58cb93dff751648af5ec6e05777",
  "compile_time" : "Wed Mar 2 10:34:48 UTC 2022",
  "compiled_by" : "root",
  "compiled_in" : "5e6b6f1167f7",
  "release_date" : "Wed Mar 2 10:34:48 UTC 2022",
  "machine" : "x86_64",
  "doc" : "https://fiware-orion.rtfd.io/en/3.6.0/",
  "libversions": {
     "boost": "1_66",
     "libcurl": "libcurl/7.61.1 OpenSSL/1.1.1k zlib/1.2.11 nghttp2/1.33.0",
     "libmosquitto": "2.0.12",
     "libmicrohttpd": "0.9.70",
     "openssl": "1.1",
     "rapidjson": "1.1.0",
     "mongoc": "1.17.4",
     "bson": "1.17.4"
  }
}
}

然后我插入一个条目使用：

查询：

'http://localhost:1026/v2/entities' \
  -H 'Content-Type: application/json' \
  -d '
{
    "id": "urn:ngsi-ld:Store:001",
    "type": "Store",
    "address": {
        "type": "PostalAddress",
        "value": {
            "streetAddress": "Bornholmer Straße 65",
            "addressRegion": "Berlin",
            "addressLocality": "Prenzlauer Berg",
            "postalCode": "10439"
        },
        "metadata": {
            "verified": {
                "value": true,
                "type": "Boolean"
            }
        }
    },
    "location": {
        "type": "geo:json",
        "value": {
             "type": "Point",
             "coordinates": [13.3986, 52.5547]
        }
    },
    "name": {
        "type": "Text",
        "value": "Bösebrücke Einkauf"
    }
}'

回复：

HTTP/1.1 201 Created Connection: Keep-Alive Content-Length: 0 Location: /v2/entities/urn:ngsi-ld:Store:003?type=Store Fiware-Correlator: f32e6e46-c520-11ec-b804-0242ac130002

接下来，我进行查询：查询：

'http://localhost:1026/v2/entities' \
-d 'type=Store' \
-d 'options=keyValues'

我得到回复：

{"error":"Internal Server Error","description":"Error at querying MongoDB: Error&#61;2, Details&#61;&#39;Response status code does not indicate success: BadRequest &#40;400&#41;&#59; Substatus: 0&#59; ActivityId: fde36487-2dd9-44a4-a719-99453acdd618&#59; Reason: &#40;Response status code does not indicate success: BadRequest &#40;400&#41;&#59; Substatus: 0&#59; ActivityId: fde36487-2dd9-44a4-a719-99453acdd618&#59; Reason: &#40;Response status code does not indicate success: BadRequest &#40;400&#41;&#59; Substatus: 0&#59; ActivityId: fde36487-2dd9-44a4-a719-99453acdd618&#59; Reason: &#40;Message: {&quot;Errors&quot;:[&quot;The index path corresponding to the specified o"}

当我转到 Azure cosmosdb 仪表板时，我可以看到该条目。所以我不确定这里出了什么问题。

能否请您建议如何解决此问题？

解决方案已发布。在这种特殊情况下，根据问题评论中的@anupam 反馈，解决方案是这一步：

You need to create an index at creDate (e.g. db.entities.createIndex({creDate:1})) and maybe more, if you use orderBy param in your NGSIv2 queries. More detail here
