Azure function cosmos db sql 在字符串数组上查询数组

Question

I' using Azure Functions and Cosmos DB with javascript to make the following query:

SELECT * FROM Posts p WHERE ARRAY_CONTAINS(p.audience, "username_1")

It works when I try it on the website but requires the quotes. However, in my function.json I have:

{
  "bindings": [
    {
      "authLevel": "anonymous",
      "name": "req",
      "type": "httpTrigger",
      "direction": "in",
      "methods": [
        "get"
      ],
      "route": "getFeed/{username}"
    },
    {
      "name": "res",
      "type": "http",
      "direction": "out"
    },
    {
      "type": "cosmosDB",
      "name": "userItem",
      "databaseName": "TwitterClone",
      "collectionName": "Users",
      "connectionStringSetting": "CosmosDBConnection",
      "direction": "in",
      "sqlQuery" : "SELECT * FROM Posts p WHERE ARRAY_CONTAINS(p.audience, {username})"
    }
  ],
  "disabled": false

}

And I just get no results. I guess it is because of the lack of quotes around {username} ...So how do I add quotes or get over the issue?

Here is an example document:

{
    "author_username": "username_2",
    "audience": [
        "username_1",
        "username_3"
    ],
}

Can you try this?

SELECT * FROM posts p where ARRAY_CONTAINS(p.auience, {{username:{username}}}, true)
