FineUploader 错误获取 Azure Blob 存储 URI

Question

我正在尝试将 FineUploader React 库实施到我的 React 应用程序中，以将文件上传到我的 Azure Blob 存储。

似乎出于某种原因，FineUploader 正在获取错误的 blob 存储 URI。

这就是我在测试组件中实例化 FineUploader 的方式：

import React, { Component } from 'react';

import FineUploaderAzure from 'fine-uploader-wrappers/azure'
import Gallery from './gallery/index';

const uploader = new FineUploaderAzure({
    options: {
        cors: {
            expected: true,
            sendCredentials: true
        },
        signature: {
            endpoint: 'https://myapp.com/api/getsas'
        },
        request: {
            endpoint: 'https://myaccount.blob.core.windows.net/test-container'
        },
        uploadSuccess: {
            endpoint: 'https://myapp.com/api/done'
        }
    }
})

class Index extends Component {
    render() {
        return (
            <Gallery uploader={uploader} />
        )
    }
}

export default Index;

这是我在控制台中看到的错误。看起来 FineUploader 为 blob 存储使用了错误的 URI。

知道是什么原因造成的吗？

更新：根据@GauravMantri 的建议，我在选项部分将 endpoint 更改为 containerUrl 但这似乎也没有帮助。这是它的样子：

const uploader = new FineUploaderAzure({
    options: {
        cors: {
            expected: true,
            sendCredentials: true
        },
        signature: {
            endpoint: 'https://myapp.com/api/getsas'
        },
        request: {
            containerUrl: 'https://myaccount.blob.core.windows.net/test-container'
        },
        uploadSuccess: {
            endpoint: 'https://myapp.com/api/done'
        }
    }
})

这是我通过 Postman 发送请求时得到的 SAS：我发送的请求是：

http://example.com/api/files/get/sas?blobUri=https://myaccount.blob.core.windows.net/test-container/test.txt&_method=put

这是我收到的 SAS：

"?sv=2017-04-17&sr=b&sig=7pXTnI2r8uGyZms12T9cRvHg1XlLI53ZJtwPUwGElnY%3D&st=2017-12-28T14%3A02%3A56Z&se=2017-12-28T14%3A22%3A56Z&sp=w"

我成功了。基本上有几点需要牢记：

在您的 FineUploader 配置中，您将需要 endpoint 属性并且应该具有您要上传到的 blob 容器的 URL。这就是我的代码中配置的样子：

var uploader = new qq.azure.FineUploader({
    debug: true,
    element: document.getElementById("uploader"),
    cors: {
        expected: true,
        sendCredentials: false
    },
    signature: {
        endpoint: 'http://localhost:63194/users/sas'
    },
    request: {
        endpoint: 'https://account-name.blob.core.windows.net/container-name'
    },

})

用于获取共享访问签名 (SAS) 的 API 应该 return blob URL + SAS Token。 API 的 blobUrl 参数应该是 blob 的绝对值 URL。这是我用于 API 的代码（请不要按原样使用它，因为下面的代码没有考虑 _method 参数）：

[Route("sas")]
[HttpGet]
public async Task<HttpResponseMessage> Sas(string blobUri)
{
    var credentials = new StorageCredentials("account-name", "account-key");
    var blob = new CloudBlockBlob(new Uri(blobUri), credentials);
    var sasParameters = new SharedAccessBlobPolicy()
    {
        SharedAccessExpiryTime = DateTime.UtcNow.AddHours(1),
        Permissions = SharedAccessBlobPermissions.Write
    };
    var sasToken = blob.GetSharedAccessSignature(sasParameters);
    var returnValue = blob.Uri.AbsoluteUri + sasToken;
    var resp = new HttpResponseMessage(HttpStatusCode.OK);
    resp.Content = new StringContent(returnValue, System.Text.Encoding.UTF8, "text/plain");
    return resp;
}

我从这里下载了 Fine Uploader Azure 相关文件：https://fineuploader.com/customize.html 并用它创建了一个简单的 HTML 页面来测试它。这是我的 HTML 页面的样子：

            element: document.getElementById("uploader"),
            cors: {

            },

        })
    </script>
</body>

一旦我运行这段代码，我就可以毫无问题地上传我的 blob 容器中的文件。
