Send file to temp blob storage in #MSDyn365FO

In this post I will talk about sending a file to a temporary blob storage. A little warning before I get into it.

This is using the Microsoft’s blob storage that is provisioned for us. I haven’t given it a lot of thought on how it would behave in production. Take it at your own risk.

Lets start by looking back on a couple of posts last month on printing a report to a byte array.

You can use those sample pieces of code to get a report as a stream and send it to the below code.

if (stream)
{
    str fileName = 'myfile';
    str contentType = 'application/pdf';
    str fileExtension = SRSPrintDestinationSettings::findFileNameType(SRSReportFileFormat::PDF, SRSImageFileFormat::BMP);

    FileUploadTemporaryStorageStrategy fileUploadStrategy = new FileUploadTemporaryStorageStrategy();
    FileUploadTemporaryStorageResult fileUploadResult = fileUploadStrategy.uploadFile(stream, fileName + fileExtension, contentType , fileExtension);

    if (fileUploadResult == null || !fileUploadResult.getUploadStatus())
    {
        warning("@ApplicationPlatform:FileUploadFailed");
    }
    else
    {
        downloadUrl = fileUploadResult.getDownloadUrl();
        if (downloadUrl == "")
        {
            throw Exception::Error;
        }
    }
}

A download URL will be generated for you. The URL is going to be public and with an expiration (15 minutes I believe).

Below is an error if you try to access it after the expiration period.
