C# Azure函数HttpTrigger，带有Cosmos DB输入

我正在尝试创建一个带有cosmos DB输入绑定的Azure函数HttpTrigger。 但它给了我一个类型错误

以下是我正在尝试的：

public static async Task<IActionResult> Run(IReadOnlyList<Document> inputDocs, HttpRequest req, IAsyncCollector<Document> outputDocs, ILogger log)
{
}

---

有人能帮我输入吗？

请看这里的一个例子，这个例子与您正在做的差不多：

[FunctionName（“CosmosDBSample”）]
公共静态HttpResponseMessage运行(
[HttpTrigger（AuthorizationLevel.Anonymous，“get”）]HttpRequestMessage请求，
[DocumentDB（“test”、“test”、connectionString=“CosmosDB”、sqlQuery=“按c顺序从c中选择前2个*）]IEnumerable文档）
{
返回请求CreateResponse（HttpStatusCode.OK，文档）；
}

请参见此处的示例，该示例与您正在做的工作基本相同：

[FunctionName（“CosmosDBSample”）]
公共静态HttpResponseMessage运行(
[HttpTrigger（AuthorizationLevel.Anonymous，“get”）]HttpRequestMessage请求，
[DocumentDB（“test”、“test”、connectionString=“CosmosDB”、sqlQuery=“按c顺序从c中选择前2个*）]IEnumerable文档）
{
返回请求CreateResponse（HttpStatusCode.OK，文档）；
}
