azure - 是否可以使用 1 个输出绑定(bind)在 cosmosDB 中创建 2 个或更多文档

Question

需要使用 Azure Function 在 CosmosDB 容器中创建 2 个文档，是否可以仅使用一个出绑定(bind)？我认为替代方案是使用 Cosmos DB 客户端。

函数.js

{
    "bindings": [{
            "name": "documents",
            "type": "cosmosDBTrigger",
            "direction": "in",
            "leaseCollectionName": "leases",
            "connectionStringSetting": "db_DOCUMENTDB",
            "databaseName": "db",
            "collectionName": "container1",
            "createLeaseCollectionIfNotExists": true
        },
        {
            "name": "inputDocumentOut",
            "type": "cosmosDB",
            "databaseName": "db",
            "collectionName": "container2",
            "createIfNotExists": false,
            "partitionKey": "{_partitionKey}",
            "connectionStringSetting": "db_DOCUMENTDB",
            "direction": "out"
        }
    ]
}

index.js

module.exports = async function(context, documents, inputDocumentOut) {

    context.log('JavaScript cosmos-trigger function processed a request.');

    if (!!documents && documents.length > 0) {
         // code ...
    }

    return {
        inputDocumentOut: [ doc1, doc2 ] // ???
    }

};

是的，只需将一组文档而不是单个文档传递给输出绑定(bind)即可:

module.exports = async function(context, documents) {

    context.log('JavaScript cosmos-trigger function processed a request.');
    var documentsToSave = [];
    if (!!documents && documents.length > 0) {
         // code ...
         // maybe call documentsToSave.push({.. some document schema to save..});
    }

    context.bindings.inputDocumentOut = documentsToSave;
};
