宇宙触发器未触发

Question

我已经使用Visual Studio创建了cosmosdb和Azure函数1.0。我在local.settings.json中添加了cosmosdb connectionstring和storageaccount密钥，但在cosmos中添加或修改时，我的azure函数未触发。

[FunctionName("Function1")]
        public static void Run([CosmosDBTrigger(
            databaseName: "cdb",
            collectionName: "myc",
            ConnectionStringSetting = "DBConnection",
    LeaseCollectionName = "leases")]IReadOnlyList<Document> input,
TraceWriter log)
        {
            if (input != null && input.Count > 0)
            {
                log.LogInformation("Documents modified " + input.Count);
                log.LogInformation("First document Id " + input[0].Id);
            }
        }


{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "Storage account key",
    "AzureWebJobsDashboard": "Storage account key",
    "DBConnection": "Cosmos db connection string"
  }
}
