blob

问题 I'm building an online csv converter that allows a user to upload a csv file and download the processed csv output file. Everything works fine, except the dowloaded file has a name that looks like "6fd665aa-74d7-4b4e-96e1-38aea0cca9e6.csv" (it changes every time) that has nothing to do with the input file's name. How can I change this downloaded file name ? const processedStr = convertCSV(text); const myBlob = new Blob([processedStr], {type : 'text/csv'}); dllink.href = window.URL

问题 Can someone help with this please? I am following the Java JDK samples, there are lots of examples on how to manage containers and blobs, however, nothing saying how to move from one storage container onto another. Eg I have a blob on StorageOne/ContainerOne/BlobName need to be moved to Storage2/ContainerTwo/BlobName I am looking at this site https://github.com/Azure/azure-sdk-for-java/blob/master/sdk/storage/azure-storage-blob/README.md hoever no luck. Also I have managed to connect via

问题 On the client side, I am sending a blob audio (wav) file. On the server side, I am trying to convert the blob file to an audio wav file. I did the following: blob = request.FILES['file'] name = "TEST.wav" audio = wave.open(name, 'wb') audio.setnchannels(1) audio.writeframes(blob.read()) I thought that converting the blob would be similar to converting a blob image to a jpeg file, but was very incorrect in that assumption. That didn't work; I get an error - "Error: sample width not specified."

问题 I have a binary file (python pickle file, to be exact). Whenever such a file is requested, I create one on server side, and then send it to the client via flask's send_file as an AJAX request. Next, I need to download this file automatically to the client side, so I have used this answer. The problem is that, the created file on the server normally has a size 300 Bytes, and the file downloaded on the client side is of the size >500 Bytes. Plus whenever I try to reuse the pickle file, it doesn

问题 I'm trying to create an audio recorder app using ReactJS. I used the npm package react-mic to serve the purpose. But the recordings were saved as a blob object. How to play the recorded file (blob object) in the browser? And how to upload this as an audio file to online storage? (like firebase) 回答1: You could try using this: https://www.npmjs.com/package/react-player From the docs: class App extends Component { render () { return <ReactPlayer url='<--YOUR BLOB -->' playing /> } } And a more
