Azure的BLOB授权头 [英] Azure blob authorization header

问题描述

我试图使用改装上传到从Xamarin的iOS应用程序蔚蓝Blob存储。这是接口的配置我使用了改装：

  [标题（X-MS-BLOB类型：BlockBlob）]
[放（/ {文件名}）]
任务＆LT;布尔＆GT; UploadAsync（[正文]字节[]的内容，串sasTokenKey，
[标题（内容类型）]串的contentType）;
 

凡sasTokenKey参数如下：

<$p$p><$c$c>\"/content-default/1635839001660743375-66f93195-e923-4c8b-a3f1-5f3f9ba9dd32.jpeg?sv=2015-04-05&sr=b&sig=Up26vDxQikFqo%2FDQjRB08YtmK418rZfKx1IHbYKAjIE%3D&se=2015-11-23T18:59:26Z&sp=w\"

这是我如何使用改装调用蔚蓝色的斑点服务器：

  VAR myRefitApi = RestService.For＆LT; IMyRefitAPI＆GT;（https://myaccount.blob.core.windows.net）;
myRefitApi.UploadAsync（photoBytes，sasTokenKey，图像/ JPEG
 

但是我收到如下错误：

 响应状态code并不表示成功：403（服务器失败
验证请求。确保授权头的值
形成正确包括签名。）
 

在SAS网址是工作的罚款，如果我直接调用它像这样

  VAR内容=新StreamContent（流）;
            content.Headers.Add（内容类型，JPEG）;
            content.Headers.Add（X-MS-斑点型，BlockBlob）;
VAR任务= HttpClient.PutAsync（新的URI（sasTokenUrl），内容）;
task.Wait（）;
 

所以基本上我只是试图做重新安装使用同样的事情。
任何想法如何获得与重新安装的Azure Blob存储工作？

谢谢！

[更新]我现在能字节上传到蔚蓝色的斑点服务器，但有些事情似乎因为我无法查看图像是错误的字节数据。这里是code我使用转换为字节数组。

 字节[]字节;
使用（VAR毫秒=新的MemoryStream（））
{
   stream.Position = 0;
   stream.CopyTo（毫秒）;
   ms.Position = 0;
   字节= ms.ToArray（）;
}
 

[更新]得到了它的固定使用，而不是字节数组流！

解决方案

我看到％2F％和3D，我很好奇，如果改装是这些编码第二次。试着发送令牌没有对其进行编码。

I am trying to use refit to upload to azure blob storage from a Xamarin iOS application. This is the interface configuration I am using for Refit:

[Headers("x-ms-blob-type: BlockBlob")]
[Put("/{fileName}")]
Task<bool> UploadAsync([Body]byte[] content, string sasTokenKey,
[Header("Content-Type")] string contentType);

Where the sasTokenKey parameter looks like this:

"/content-default/1635839001660743375-66f93195-e923-4c8b-a3f1-5f3f9ba9dd32.jpeg?sv=2015-04-05&sr=b&sig=Up26vDxQikFqo%2FDQjRB08YtmK418rZfKx1IHbYKAjIE%3D&se=2015-11-23T18:59:26Z&sp=w"

This is how I am using Refit to call the azure blob server:

var myRefitApi = RestService.For<IMyRefitAPI>("https://myaccount.blob.core.windows.net");
myRefitApi.UploadAsync(photoBytes, sasTokenKey, "image/jpeg"

However I am getting the follow error:

Response status code does not indicate success: 403 (Server failed to 
authenticate the request. Make sure the value of Authorization header is 
formed correctly including the signature.)

The SAS url is working fine if I call it directly like this

var content = new StreamContent(stream);
            content.Headers.Add("Content-Type", "jpeg");
            content.Headers.Add("x-ms-blob-type", "BlockBlob");
var task = HttpClient.PutAsync(new Uri(sasTokenUrl), content);
task.Wait();

So basically I am just trying to do the same thing using Refit. Any idea how to get Refit working with Azure Blob Storage?

Thanks!

[UPDATE] I am now able to upload the bytes to the azure blob server but something seems to be wrong with the byte data because I am not able to view the image. Here is the code I am using to convert to byte array.

byte[] bytes;
using (var ms = new MemoryStream())
{
   stream.Position = 0;
   stream.CopyTo(ms);
   ms.Position = 0;
   bytes = ms.ToArray();
}

[UPDATE] Got it fixed by using stream instead of byte array!

解决方案

I see %2F and %3D and I'm curious if refit is encoding those a second time. Try sending the token without encoding it.
