Question

我正在尝试自动化（用于测试自动化）上载/下载/验证Azure云中托管的应用程序的csv文件数据，并关注以下文章：

https://medium.com/@fakiolinho/handle-blobs-requests-with-axios-the-right-way-bb905bdb1c04

并尝试按照指示实施它，但是，在以下（action.js）中找不到' actionTypes '：

import * as types from './actionTypes';并迷路了。

[Error: Cannot find module './actionTypes']

根据我的学习，我相信axios或fetch可以用于执行任务（我更喜欢axios），并且我需要一些帮助来简化解决方案或在正确的方向上完成任务。

我知道有人问过与此场景相关的类似问题，但是，到目前为止，这些问题都没有解决，或者属于不同的工具和技术栈。

请提出更好的方法，工具或示例。

Blob存储链接的示例为：

尝试使用axios：

var axios = require('axios').default;
var fs = require('fs');
var crypto =  require('crypto');

var storageKey = "<your storage key>"
var accountName = "<your storage account name>"
var containerName="<your container name>"
var fileName="<file name>"
var filePath = "<file path ,including file name>"


var fileLength= fs.statSync(filePath).size
var fileStream = fs.createReadStream(filePath);

var blobType ="BlockBlob"
var date = new Date().toUTCString()
var blobServiceVersion = "2014-02-14"

var storageBlobEndpoint = "https://"+ accountName +".blob.core.windows.net"
var requestURL = storageBlobEndpoint + "/" + containerName + "/" + fileName
var requestMethod = "PUT"


var canonicalizedHeaders = "x-ms-blob-type:"+ blobType +"\nx-ms-date:"+ date +"\nx-ms-version:" + blobServiceVersion;
console.log("headers :"+canonicalizedHeaders);
var canonicalizedResource = accountName + "/" + containerName + "/" +  fileName

var stringToSign = requestMethod+"\n\n\n"+fileLength+"\n\napplication/x-www-form-urlencoded\n\n\n\n\n\n\n" + canonicalizedHeaders + "\n/" + canonicalizedResource

var signature = crypto.createHmac('sha256', Buffer.from(storageKey, 'base64')).update(stringToSign, 'utf-8').digest('base64');

var authorizationHeader = "SharedKey "+accountName + ":" + signature


  const result = axios({
        baseURL: requestURL,
        method: requestMethod,
        data:fileStream,
        headers: {
            'Content-Length':fileLength,
            'x-ms-blob-type': blobType,
            'x-ms-date':date,
            'x-ms-version':blobServiceVersion,
            'Authorization' : authorizationHeader
            }
        }).then(function (response) {
    console.log(response);
  })
  .catch(function (error) {
    console.log(error);
  })
  .finally(function () {
    //add finally function here if needed 
  });

使用剩余的API将文件上传到存储非常复杂。使用SDK会容易得多。希望对您有所帮助。
