在模拟 Azure CloudBlob 方面需要帮助

如何解决在模拟 Azure CloudBlob 方面需要帮助

这是我需要测试的功能

    [FunctionName("Getimage")]
    public static async Task<IActionResult> Run(
        [HttpTrigger(AuthorizationLevel.Function,"get","post",Route = "Getimage/{filename}")] HttpRequest req,string filename,[Blob("%blobContainerName%/{filename}",FileAccess.Read,Connection = "StorageConnectionAppSetting")] CloudBlobContainer blob,ILogger log)
    {
        try
        {
            CloudBlob img = blob.GetBlobReference(filename);
            Stream test = await img.OpenReadAsync();

            return new FileStreamResult(test,"image/jpeg");
        }
        catch (Exception ex)
        {
            log.LogError(ex.StackTrace);
            return new BadRequestResult();
        }
    }

这是我目前编写的单元测试代码。

    public async Task TestOkRequestGetimage()
    {
        _cloudBlobContainer = new Mock<CloudBlobContainer>(new Uri("http://mytest"));

        _cloudBlob = new Mock<CloudBlob>(new Uri("http://mytest.com"));

        Dictionary<string,StringValues> query = new Dictionary<string,StringValues>();

        _cloudBlobContainer.Setup(x => x.GetBlobReference(It.IsAny<string>()))
            .Returns(_cloudBlob.Object);

        _cloudBlob.Setup(x => x.OpenReadAsync()).ReturnsAsync(It.IsAny<Stream>());

        var httpReq = HttpRequestSetup(query,"");

        var reqMock = new Mock<HttpRequest>();

        var response = await Getimage.Run(reqMock.Object,"test",_cloudBlobContainer.Object,_log.Object);

        response.Should().BeOfType<FileStreamResult>();
    }

这是错误 TestOkRequestGetimage threw exception: System.ArgumentException: Invalid blob address 'http://mytest.com/',missing container information (Parameter 'blobAddress')

不知道为什么我不能像初始化 CloudBlobContainer 一样初始化 CloudBob。有什么提示吗？
