FineUploader获取Azure Blob存储URI时出错

azure-blob-storage fine-uploader azure

Sam · 技术社区 · 7 年前

我正在尝试将FineUploader React库实现到我的React应用程序中,以将文件上载到我的Azure Blob存储。

看起来出于某种原因,FineUploader错误地获取了blob存储URI。

这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对blob存储使用了错误的URI。

你知道这是什么原因吗?

更新: 根据@GauravMantri的建议,我改变了 endpoint 到 containerUrl 在选项部分,但这似乎也没有帮助。下面是它的样子:

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'
        }
    }
})

以下是我通过邮递员发送请求时收到的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。基本上有几件事需要记住:

在您的 FineUploader 配置,您需要 endpoint 属性,该属性应具有要上载的blob容器的URL。以下是我的代码中的配置:

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'
    },

})

获取共享访问签名(SAS)的API应返回 blob URL + SAS Token . 这个 blobUrl API的参数应该是blob的绝对URL。这是我用于API的代码(请不要按原样使用,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 并使用它创建一个简单的HTML页面来测试它。以下是我的HTML页面的外观:

一旦我运行了这段代码,我就可以毫无问题地将文件上传到blob容器中。
