ClientException: XMLHttpRequest error., uri=https://fileStore1.blob.core.windows.net/myfile/pdf-27-11-2023-15-58-4-0-0.pdf

Hello,
I am using a web service hosted on AzureCloud and I am using a clientid/client_secret to get a token and then a url allowing me to upload a file,
so does can we use your lib with this scenario ?
I have an url like:

https://mystoragedev.blob.core.windows.net/bab5b619-3634-eb11-9fb4-501ac53c3bc8/a992fc63-1ee7-ec11-b656-501ac53ca96e/Files/ATestFile2.jpg?sv=2020-02-10&st=2022-06-09T08%3A12%3A22Z&se=2022-06-10T08%3A12%3A22Z&sr=b&sp=w&rscd=attachment%3B+filename%3D%22ATestFile2.jpg%22&rsct=image%2Fjpeg&sig=cu2x%2BrgOW4%2FDAlmQgar5u1%2BcHu86pezrA%2BdrtfwfGag%3D

but it seems with your lib I have to use a ConnectionString...

This library has been really helpful so thanks for all the hard work on it!

I found an issue yesterday, which took a while to figure out what was going on.

I'm setting content type for an image upload, but when the signature is created it is adding an array object instead of the single content type. The server must strip the single content-type from the array before it computes the hash so it doesn't match.

`final mimeType = lookupMimeType(fileName);

  final azureStorage = AzureStorage.parse(cloudStorageAccount);
  await azureStorage.putBlob(blobUrl,
      bodyBytes: bodyBytes, contentType: mimeType);`

It's a simple fix to get firstOrNull to get the first content type (I can't see there being mixed types for this use case):

final ct = request.headers['Content-Type']?.firstOrNull ?? '';

Happy to raise a PR, I tried to create a fork but couldn't push to it. Do I need to be a contributer?

Hi,

I was using azblob without a problem, but now, on flutter web, I get the following errors when trying to upload a file :
"Refused to set unsafe header content-length"
followed by :
"Server failed to authenticate the request"

Any idea of the origin / workaround ?
Thanks

Julien

Hi @kkazuo thanks for the package, Can you provide an callback which will give the upload & download progress of a file. I tried converting the package to dio as dio by default have this feature. But from azure I got Authentication failed & some error about the produced digest. So it will helpful if you add this feature or else covert the rest-api calls to dio.

Thank you for sharing this great lib !
I used it for syncing vocal messages on azure:

There are two points that you might be interested in including in azblob :

• xml audio file parsing example :

  • lib/src/azure_blob/audio_file_parser.dart

• handling http.ClientException and Connection closed while receiving data

  • lib/src/azure_blob/azblob_base.dart (e.g. line 143)

Thank you very much for creating this package! It's been very helpful to me. I recently found myself needing functionality to delete a file within azure blob storage. I implemented this with the following:

Future<http.StreamedResponse> deleteBlob(String path) async {
    var request = http.Request('DELETE', uri(path: path));
    sign(request);
    return request.send();
  }

Please let me know if you find this helpful and would like to add this, or would like a pull request for it.

there is no implementation how to getblob link

Need to upload large files using chunks to azure. Any suggestion's @kkazuo
