node.js - 哈希与 Azure Blob 存储不匹配(完整性检查失败)

Question

我正在关注http://willi.am/blog/2014/07/03/azure-blob-storage-and-node-downloading-blobs/ .

然而，尽管代码完全相同，当我下载 blob Azure 时却出现错误:

[错误:哈希不匹配(完整性检查失败)，预期值为...]

正在运行的行是 blobService.getBlobToText，其中 blobService 是与 Azure 的连接(createBlobService...)

发生什么事了？ :S

我的代码如下:

    // Azure test
    function downloadImageAsText(blobService, containerName, blobName) {

         blobService.getBlobToText(
              containerName,
              blobName,
              function(err, blobContent, blob) {
                  if (err) {
                      console.error("Couldn't download blob %s", blobName);
                      console.error(err);
                  } else {
                      console.log("Sucessfully downloaded blob %s", blobName);
                      console.log(blobContent);
                  }
              });

    }

    function uploadImage(blobService, containerName, blobName, fileName) {

      blobService.getBlobProperties(
        containerName,
        blobName,
        function(err, properties, status) {
            if (status.isSuccessful) {
                // Blob exists
            } else {
                blobService.createBlockBlobFromLocalFile(
                    containerName,
                    blobName,
                    fileName,
                    function(error, result, response){
                        if(error){
                            console.log("Couldn't upload file %s", fileName);
                            console.error(error);
                        } else {
                            console.log('File %s uploaded successfully', fileName);
                            downloadImageAsText(blobService, containerName, blobName);
                        }
                    });
            }
        });
    }


    function testAzure() {

      accountName / hash = my details

      var storage = require('azure-storage');
      var blobService = storage.createBlobService(accountName, hash);
      var containerName = 'tst';
      var blobName = 'test.png';
      var fileName = 'test.png';

      blobService.createContainerIfNotExists(containerName, function(err, result, response) {
          if (err) {
              console.log("Couldn't create container %s", containerName);
              console.error(err);
          } else {
              if (result) {
                  console.log('Container %s created', containerName);
                  uploadImage(blobService, containerName, blobName, fileName);
              } else {
                  console.log('Container %s already exists', containerName);
                  uploadImage(blobService, containerName, blobName, fileName);
              }
          }
      });
    }

    function startServer() {
      http = require('http');
      const PORT = 8080;
      var server = http.createServer(handleRequest);
      server.on('listening',function(){
        console.log("Server listening on: http://178.62.117.207:%s", PORT);
      });
      server.listen(PORT);
    }

    startServer();
    testAzure();

如果其他人遇到这种情况；当您存储 Buffer 对象但检索 string 时会发生这种情况。
