[BUG]Setting content type while uploading streams to azure blob storage is not working (Using 12.27.1 version)

[vasavi-gopisetty]

Here is my sample code. Content type is not setting however I try.
BlockBlobClient blockBlobClient = blobContainerClient.getBlobClient("image.png").getBlockBlobClient();
blockBlobClient.setHttpHeaders(new BlobHttpHeaders().setContentType("image/png"));

BlobOutputStream blobOutputStream=null;
try {

blobOutputStream = blockBlobClient.getBlobOutputStream();

ByteArrayInputStream bis = new ByteArrayInputStream(inputStream.readAllBytes());
int next = bis.read();
while (next != -1) {
    blobOutputStream.write(next);
    next = bis.read();
}  

}finally {
blobOutputStream.close();
}

Hey @vasavi-gopisetty

You are facing this issue because the content type is being set before the blob upload is complete. This may cause the content type to be overwritten or not applied correctly.
To resolve this issue, try setting the content type after the blob upload is complete.

Here's the revised code:

BlockBlobClient blockBlobClient = blobContainerClient.getBlobClient("image.png").getBlockBlobClient();

BlobOutputStream blobOutputStream = null;
try {
blobOutputStream = blockBlobClient.getBlobOutputStream();
ByteArrayInputStream bis = new ByteArrayInputStream(inputStream.readAllBytes());
int next = bis.read();
while (next != -1) {
blobOutputStream.write(next);
next = bis.read();
}
} finally {
blobOutputStream.close();
}

// Set the content type after the upload
blockBlobClient.setHttpHeaders(new BlobHttpHeaders().setContentType("image/png"));

Hi, Thank you so much for reaching out. My issue is resolved. I was setting conent type using options. Here is the sample code BlockBlobSimpleUploadOptions options = new BlockBlobSimpleUploadOptions(dataStream, dataStream.available()) .setTier(AccessTier.HOT) .setHeaders(new BlobHttpHeaders().setContentType("image/png"); Thanks, Vasavi From: gunjansingh-msft ***@***.***> Sent: Wednesday, December 11, 2024 11:20 PM To: Azure/azure-sdk-for-java ***@***.***> Cc: Vasavi Gopisetty ***@***.***>; Mention ***@***.***> Subject: Re: [Azure/azure-sdk-for-java] [BUG]Setting content type while uploading streams to azure blob storage is not working (Using 12.27.1 version) (Issue #41744) You don't often get email from ***@***.*** Learn why this is important<https://aka.ms/LearnAboutSenderIdentification> I have reproduced the issue and found that the revised code below works perfectly when the content type is set after the upload completes: public static void main(String[] args) { String connectionString = "DefaultEndpointsProtocol=https;AccountName=gunjanfns;AccountKey=Bw+G0p+NR/Vxo3pQvm9d299Q/VIideDu7b3/H9/OJvooiiXyYQ/ym5l9TVRMo2MfYKhWF96KPvsp+AStZd9CfQ==;EndpointSuffix=core.windows.net"; String containerName = "test"; String blobName = "image.png"; String filePath = "C:\Users\gunjansingh\Downloads\image.png"; BlobContainerClient blobContainerClient = new BlobServiceClientBuilder() .connectionString(connectionString) .buildClient() .getBlobContainerClient(containerName); BlockBlobClient blockBlobClient = blobContainerClient.getBlobClient(blobName).getBlockBlobClient(); BlobOutputStream blobOutputStream = null; BufferedInputStream inputStream = null; try { blobOutputStream = blockBlobClient.getBlobOutputStream(); inputStream = new BufferedInputStream(new FileInputStream(new File(filePath))); ByteArrayInputStream bis = new ByteArrayInputStream(inputStream.readAllBytes()); int next = bis.read(); while (next != -1) { blobOutputStream.write(next); next = bis.read(); } } catch (IOException e) { e.printStackTrace(); } finally { try { if (blobOutputStream != null) { blobOutputStream.close(); } if (inputStream != null) { inputStream.close(); } } catch (IOException e) { e.printStackTrace(); } } // Set the content type after the upload blockBlobClient.setHttpHeaders(new BlobHttpHeaders().setContentType("image/png")); } — Reply to this email directly, view it on GitHub<#41744 (comment)>, or unsubscribe<https://github.com/notifications/unsubscribe-auth/BLCAIVGKYJ2I3G2HJEK5CP32FAUVRAVCNFSM6AAAAABNXZAFYKVHI2DSMVQWIX3LMV43OSLTON2WKQ3PNVWWK3TUHMZDKMZVHAZTQNRQGQ>.
