Azure 媒体服务 CreateWithHttpMessagesAsync - 操作返回无效状态代码 : "BadRequest" -

Question

我将 Azure Media Services v3 与 Azure Function v3 应用程序结合使用，在尝试从 https url 创建新作业时遇到问题。

我在提交作业的 Azure Function 中有以下方法。

private static async Task<Job> SubmitJobAsync(IAzureMediaServicesClient client, string transformNam, string jobName, string fileUrl) {
    JobInputHttp jobInput = new JobInputHttp(files: new [] { fileUrl });
    JobOutput[] jobOutputs = 
    {
        new JobOutputAsset(jobName)
    }

    Job job = await client.Jobs.CreateAsync(
        _resourceGroupName,
        _accountName,
        transformName,
        jobName,
        new Job
        {
            Input = jobInput,
            Outputs = jobOutputs
        },
        CancellationToken.None);

    return job;
}

实际创建作业的线路失败 await client.Jobs.CreateAsync(... 并返回异常，并显示以下消息:

Operation returned an invalid status code 'BadRequest'

堆栈跟踪:

at Microsoft.Azure.Management.Media.JobsOperations.CreateWithHttpMessagesAsync(String resourceGroupName, String accountName, String transformName, String jobName, Job parameters, Dictionary`2 customHeaders, CancellationToken cancellationToken) at Microsoft.Azure.Management.Media.JobsOperationsExtensions.CreateAsync(IJobsOperations operations, String resourceGroupName, String accountName, String transformName, String jobName, Job parameters, CancellationToken cancellationToken)

知道这意味着什么或者我如何进一步调试它吗？

我认为问题在于您在创建作业之前没有创建输出资源。 尝试在创建作业之前添加这些行:

string outputAssetName = jobName;

Asset outputAsset = await client.Assets.CreateOrUpdateAsync(_resourceGroupName, _accountName, outputAssetName, new Asset());

JobOutput[] jobOutputs = 
        {
            new JobOutputAsset(outputAssetName)
        }
