从 Azure VM 将文件上传到 Azure 存储

Question

我在 Node.JS 中有一些代码从用户那里获取文件并将其上传到我的 blob 存储中。

我正在使用带有此代码的azure-storage 包：

blobSvc.createBlockBlobFromLocalFile('t-uploads', 'high/' + file.name, './tmp/storage/' + file.name, function(error, result, response) {
            console.log("did come here", error, result, response);
            if (!error) {
                console.log(response);
                fs.unlink('./tmp/storage/' + file.name);
            } else {
                console.log(error);
                next(new Error("Azure High Resolution Error!"));
            }
        });

问题是，当我从 c9.io 运行代码时，该代码可以工作，但当我在我的 azure VM 上使用相同的代码时，代码无法运行。

日志（来自 Azure VM）：

没有错误，但我的节点 api 重新启动

更新

我在失败的地方尝试了这段代码

fs = require('fs')
        fs.readFile('./tmp/storage/' + file.name, 'utf8', function (err,data) {
          if (err) {
            return console.log(err);
          }
          console.log(data);
        });

因此，我可以在 azure vm 和 c9.io 上成功读取文件。所以可能不是本地权限问题。

好的，很抱歉给您带来麻烦，上传完成后，是愚蠢的 pm2 重新启动了我的应用程序。
