问题 As per the title, I have a program whereby I'm trying to add to an existing BlobkBlob using the PutBlock method: private static void UploadNewText(string text) { string fileName = "test4.txt"; string containerString = "mycontainer"; CloudStorageAccount storage = CloudStorageAccount.Parse(connection); CloudBlobClient client = storage.CreateCloudBlobClient(); CloudBlobContainer container = client.GetContainerReference(containerString); CloudBlockBlob blob = container.GetBlockBlobReference

问题 How to convert blob to base64/image? I am getting this blob through API call and I am trying to display it in a image. I have tried with stackoverflow answers but nothing could help so I just tried this. //Angular 5 code imageSrc;//global variable data = [{"image_blob":{"type":"img/jpg","data":[123,125]}}];//from api var blob1 = new Blob([new Uint8Array(data[0].image_blob.data)]); const imageUrl = URL.createObjectURL(blob1); console.log(imageUrl);//blob:http://localhost:8100/c489.etc this

问题 I am working on an image processing project where my images are saved in blob storage on Azure. My goal is to read in the blob images and apply some transformations to them, then upload them to a separate container using python. Currently, I'm able to read in the images from Azure, convert the images to arrays so I can process them, but I'm having trouble getting the arrays back to Azure as .jpg images. This is what I'm trying (where resized_image is a (243, 387, 3) array): resized_image =

问题 I'm trying to access a csv stored in Azure blob and read it into a pandas dataframe in my python script. But I'm running into issues with imports and actually reading the csv. I'm at least able to see that it exists using my python script, which looks like: import os, uuid, sys from io import StringIO import pandas as pd from azure.storage.filedatalake import DataLakeServiceClient from azure.core._match_conditions import MatchConditions from azure.storage.filedatalake._models import

问题 Azure Function (Python) triggered from file uploads to Azure Storage. Function works fine for files up to ~120MB. I just load tested with a 2GB file and the function produced the error Stream was too long. Where is this limitation documented? How would I overcome it using Python? Using boto3 library to PUT files to AWS S3 def main(myblob: func.InputStream): logging.info(f"Python blob trigger function processed blob \n" f"Name: {myblob.name}\n" f"Blob Size: {myblob.length} bytes") myblobBytes
