使用 blob 的 url 和 node.js 中的 sas 令牌下载 blob

Question

I am very new to java script. I want to download a blob file from the azure blob storage. I have the sas token and complete url to the individual block blob The url looks like this: https://xxxxxxxxxx.blob.core.windows.net/ABC/ABC/20216063/cvf.gbl

In online i have come across download methods which require container name and blob name. I dont know the container name and blob name. i have the url to the individual blob file.

How to download the blob using only sas token and the blob url using java script?

You could create an HTTP GET request and pipe its response into a writable file stream. With the below code you could download the file if you don't the blob name.

    const sasurl="your sas url";
    const https = require('https');
    const url = require('url');;
    const path = require('path');
    const fs = require('fs');
    const filename=url.parse(sasurl).pathname.split('/').pop();
    const file = fs.createWriteStream(filename);
    const request = https.get(sasurl, function(response) {
    response.pipe(file);
    });
