how to read .html file from Azure storage explorer.
through connectionstring can able to access blob.
string Template = bloburl + "file.html";
Yes you could create the html and save it to the container created.
You could make the URI for this blob public and then access it via your custom URL -- you'd have to create a CNAME for the storage container first.
Here is a good resource on how to use Blob Storage from .NET:
http://azure.microsoft.com/en-us/documentation/articles/storage-dotnet-how-to-use-blobs/
var url = TemplateMain;
var httpClient = new HttpClient();
var html = await httpClient.GetStringAsync(url);
i have tried using GetStringAsync and its working fine.

I am running node to download the sales report from google cloud storage.
I got the credentials.json file. Now the problem is every time I run my application I get "xxxxxxx#gmail.com" does not have storage.objects.get access to the Google Cloud Storage object".
Yes, this email is nowhere registered on the google cloud storage or given rights to, but it should work with the credentials alone, no?
The credentials are directly from the google cloud storage and have this information :
client_secret,project_id,redirect_uri,client_id...
My sample Code:
// Imports the Google Cloud client library.
const {Storage} = require('#google-cloud/storage');
const projectId = 'xxxxxxxxxxxxxxxxxx'
const key = 'credentials.json'
const bucketName = 'pubsite.......'
const destFileName = './test'
const fileName = 'salesreport_2020.zip'
// Creates a client
const storage = new Storage({projectId, key});
async function downloadFile() {
const options = {
destination: destFileName,
};
// Downloads the file
await storage.bucket(bucketName).file(fileName).download(options);
console.log(
`gs://${bucketName}/${fileName} downloaded to ${destFileName}.`
);
}
downloadFile().catch(console.error);
You are using the wrong type of credentials file.
Your code is written to use a service account JSON key file. You mention that the credentials file contains client_secret. That means you are trying to use OAuth 2.0 Client IDs.
Look in the file credentials.json. It should contain "type": "service_account". If you see {"installed": or {"web": at the start of the file, then you have the wrong credentials.
Creating and managing service account keys
Also, you are specifying the parameters wrong in the line:
const storage = new Storage({projectId, key});
Replace with:
const storage = new Storage({projectId: projectId, keyFilename: key});
Because you are seeing the random gmail address, that likely means the storage client is using Application default credentials instead of the ones you intend. There are two paths forward:
Embrace application default credentials. Remove the options you are passing in to the Storage constructor, and instead set the GOOGLE_APPLICATION_CREDENTIALS environmental variable to you json service account file.
Fix the Storage constructor to pass in credentials properly. The issue may be something as simple as you needing to pass the full path to the credentials file (ie /a/b/c/credentials.json). Possibly the storage options are not being processed right, try being explicit like
const storage = new Storage({projectId: 'your-project-id', keyFilename: '/path/to/keyfile.json'});
Team,
I have a blazor web assembly app, which upload the file and process it later. However , I would like to know the base path of the file from where it it picked in the machine.
My code goes as follows . Does anyone has idea to get the file path such as "C:\myfile.txt".
With the File object, I cannot achieve the full path, I can access only its memory stream.
<h1>FILE UPLAOD </h1>
<InputFile OnChange="HandleSelection" ></InputFile>
#code
{
string status;
async Task HandleSelection(IFileListEntry[] files)
{
var file = files.FirstOrDefault();
if (file != null)
{
// Just load into .NET memory to show it can be done
// Alternatively it could be saved to disk, or parsed in memory, or similar
var ms = new MemoryStream();
await file.Data.CopyToAsync(ms);
Console.WriteLine(ms);
status = $"Finished loading {file.Size} bytes from {file.Name}";
var content = new MultipartFormDataContent
{
{ new ByteArrayContent(ms.GetBuffer()),"\"upload\"", file.Name}
};
await client.PostAsync("upload", content);
}
}
}
Even if you get the fullpath (C:\myfile.txt") file won't load
by default, all browser has a security mechanism that any local disk file won't be loaded into a website until you disable that security for your website
Is it possible to download a file from AWS s3 without AWS cli? In my production server I would need to download a config file which is in S3 bucket.
I was thinking of having Amazon Systems Manger run a script that would download the config (YAML files) from the S3. But we do not want to install AWS cli on the production machines. How can I go about this?
You would need some sort of program to call the Amazon S3 API to retrieve the object. For example, a PowerShell script (using AWS Tools for Windows PowerShell) or a Python script that uses the AWS SDK.
You could alternatively generate an Amazon S3 pre-signed URL, which would allow a private object to be downloaded from Amazon S3 via a normal HTTPS call (eg curl). This can be done easily using the AWS SDK for Python, or you could code it yourself without using libraries (it's a bit more complex).
In all examples above, you would need to provide the script/program with a set of IAM Credentials for authenticating with AWS.
Just adding notes for any C# code lovers to solve problem with .Net
Firstly write(C#) code to download private file as string
public string DownloadPrivateFileS3(string fileKey)
{
string accessKey = "YOURVALUE";
string accessSecret = "YOURVALUE";;
string bucket = "YOURVALUE";;
using (s3Client = new AmazonS3Client(accessKey, accessSecret, "YOURVALUE"))
{
var folderPath = "AppData/Websites/Cases";
var fileTransferUtility = new TransferUtility(s3Client);
Stream stream = fileTransferUtility.OpenStream(bucket, folderPath + "/" + fileKey);
using (var memoryStream = new MemoryStream())
{
stream.CopyTo(memoryStream);
var response = memoryStream.ToArray();
return Convert.ToBase64String(response);
}
return "";
}
}
Second Write JQuery Code to download string as Base64
function downloadPrivateFile() {
$.ajax({url: 'DownloadPrivateFileS3?fileName=' + fileName, success: function(result){
var link = this.document.createElement('a');
link.download = fileName;
link.href = "data:application/octet-stream;base64," + result;
this.document.body.appendChild(link);
link.click();
this.document.body.removeChild(link);
}});
}
Call downloadPrivateFile method from anywhere of HTML/C#/JQuery -
Enjoy Happy Coding and Solutions of Complex Problems
Uploading an image via the Python SDK, the "Content Type" in Azure Blob storage is always "application/x-www-form-urlencoded".
Certain applications, like Twilio, require a correct content type when accessing blob files, to render an MMS message.
I would like to request the ability to set the content Type at upload, vs. having to do it in code.
(For others) As a workaround, I am using the code below (include WindowsAzure.Storage from NuGet):
using Microsoft.WindowsAzure.Storage;
using Microsoft.WindowsAzure.Storage.Blob;
static void ChangeContentType(string URI)
{
//Parse the connection string for the storage account.
const string ConnectionString = "DefaultEndpointsProtocol=https;AccountName=accountName;AccountKey=AccountKey";
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(ConnectionString);
//Create the service client object for credentialed access to the Blob service.
CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
ICloudBlob imageFile = blobClient.GetBlobReferenceFromServer(new Uri(URI));
imageFile.Properties.ContentType = "image/jpeg";
imageFile.SetProperties();
}
I'm trying to use C# for connecting to Onedrive Rest API platform, The URL that I need to connect is:
"asdfasdfLJLKJLKJK"
and the code I'm trying to run is as below:
using System.Net.Http;
using (var client = new HttpClient())
{
var content_new = new FormUrlEncodedContent(new[]{ new KeyValuePair<string, string>("access_token", "asdKJHKJH")});
var content = new FormUrlEncodedContent(values);
client.BaseAddress = new Uri("https://api.onedrive.com/v1.0");
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var response_web = await client.PostAsync("/drive", content_new);
var responseString = await response_web.Content.ReadAsStringAsync();
Console.WriteLine(responseString);
Console.ReadLine();}
But for some odd reason it fails, also would like to know if I can read the data that PostAsync sends to the server? I mean the request URL as that might help troubleshooting too.
Looking at your request you are performing a POST operation on a drive, the OneDrive API does not support that action on the drive node.
If you are looking to create a new folder or upload a file, you'll want to perform that operation on https://api.onedrive.com/drive/root or where ever you'd like the operation to happen in the user's account.
To look up all of the supported actions and example requests see the OneDrive API resource model.
