c# - Fineuploader with Azure，空图像问题

Question

我长期使用fineuploader的直接azure上传模块。我在上传图像时遇到困难。问题是，有时上传的图像是空的。当我从存储资源管理器查看它时，文件存在，但大小为 0 kb。当我从浏览器查看图像时，它显示为空白。

插件代码

var uploader = new qq.azure.FineUploader({
    debug: true,
    element: document.getElementById('fine-uploader'),
    request: {
        endpoint: 'https://xxxxx.blob.core.windows.net/assetscontainer'
    },
    signature: {
        endpoint: '/File/GetSasKey',
        cors: {
            expected: true,
            sendCredentials: false
        }
    },
    uploadSuccess: {
        endpoint: '/File/Success'
    },
    deleteFile: {
        enabled: true
    },
    callbacks: {
        onSubmit: function (id, name) {
            var extension = name.substr((name.lastIndexOf('.') + 1));
            var uuid = this.getUuid(id);
            this.setUuid(id, "JobOrder_" + uuid);
            this.setUploadSuccessParams({ entityID: 0, entityType: "orderID" }, id)

        },
        onComplete: function (id, fileName, responseJSON) {

            console.log(responseJSON);
        }
    }
});

sas生成过程代码

[Route("sas")]
[HttpGet]
[AuthorizationType("*")]
public async Task<string> GetSasKey(string blobUri)
{
    var credentials = new StorageCredentials("xxxxxxxxxxxx", "afxxxxxasfasf==");
    var blob = new CloudBlockBlob(new Uri(blobUri), credentials);
    var storageAccount = new CloudStorageAccount(credentials, true);


    var sasParameters = new SharedAccessBlobPolicy()
    {
        SharedAccessExpiryTime = DateTime.UtcNow.AddHours(1),
        Permissions = SharedAccessBlobPermissions.Write | SharedAccessBlobPermissions.Delete
    };
    var sasToken = blob.GetSharedAccessSignature(sasParameters);
    var returnValue = blob.Uri.AbsoluteUri + sasToken;
    return returnValue;
}

以及成功方法

public JsonResult Success (string blob, string uuid, string name, string container, int entityID, string entityType)
{
    //do some work
}

这可能是 Fine Uploader 的问题。

Fine Uploader 是一个开源项目，一年多前被关闭。

https://github.com/FineUploader/fine-uploader/issues/2073

如果在代码中发现安全错误，对不活动的开源项目的依赖可能会出现问题。

我的建议是更换 Fine Uploader。
