httpTrigger中的Blob绑定在VS2017 Azure函数模板中不起作用

我想通过如下所示的get请求将blob的文件名传递给httptrigger.

I want to pass the filename of blob to the httptrigger, through get request as below.

http://localhost:7071/api/CSVDataMigrationHttpTrigger/testdata.csv

天蓝色函数的代码

public static async Task<HttpResponseMessage> Run(
        [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = "CSVDataMigrationHttpTrigger/{name}")]
        HttpRequest req, string name,
        [Blob("csvdata-upload/{name}", FileAccess.Read, Connection = "AzureWebJobsStorage")]
        Stream inputBlob, ILogger log)
    {}

inputBlob参数未解析，它返回null.

但是，如果我在Blob参数中将文件名指定为"testData.csv"，则inputBlob会得到正确解析.

But if i give filename as "testData.csv" as below in the Blob parameter, then inputBlob get resolved properly.

  public static async Task<HttpResponseMessage> Run(
            [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = "CSVDataMigrationHttpTrigger/{name}")]
            HttpRequest req, string name,
            [Blob("csvdata-upload/testData.csv", FileAccess.Read, Connection = "AzureWebJobsStorage")]
            Stream inputBlob, ILogger log){}
