通过REST将消息发送到Azure服务总线 [英] send msg to Azure service bus que via REST

问题描述

Azure队列公开给REST API.要使REST调用起作用.我在POSTMAN上进行了样本测试.POST呼叫

 <代码> https://yournamespace.servicebus.windows.net/yourentity/messages 

此外，在下面的2个标头和值中传递.

标题1:

 授权:SharedAccessSignature sr = https％3A％2F％2F.servicebus.windows.net％2Fyourentity& sig =您上面代码中的签名& se = 1529928563& skn = KeyName 

示例:

  SharedAccessSignature sr = https％3A％2F％2Fservicebussoatest1.servicebus.windows.net％2Fpublishque& sig = a0wmRklbCGFCYoSCViij9gagtZV9Bg + vU =& se = 1529928563& skn = testpolicycy 

标题2:

  Content-Type:应用程序/json 

但是，即使我传递了正确的Authorization值，也收到以下错误:

401:无效的授权令牌签名

解决方案

401:无效的授权令牌签名

根据401错误，表示令牌无效.

首先，请确保您的策略有权发送邮件.

第二，如果您想使用

用邮递员对其进行测试.

标题:

  Authorization:SharedAccessSignature sr = https％3a％2f％2fyournamespace.servicebus.windows.net％2fqueuename％2fmessages& sig = SyumAUNnqWFjW2MqjwlomU％2fbblqZljq6LPJp3jpfU =％2b4％内容类型:application/xml 

身体

 < string xmlns ="http://schemas.microsoft.com/2003/10/Serialization/">这是一条消息. 

测试结果:

The Azure Queues are exposed to REST API.To make the REST call works. I ran a sample test on POSTMAN. The POST call

https://yournamespace.servicebus.windows.net/yourentity/messages

Also, Passing below 2 headers and values.

Header 1:

Authorization: SharedAccessSignature sr=https%3A%2F%2F.servicebus.windows.net%2Fyourentity&sig=yoursignature from code above&se=1529928563&skn=KeyName

Example:

SharedAccessSignature sr=https%3A%2F%2Fservicebussoatest1.servicebus.windows.net%2Fpublishque&sig=a0wmRklbCGFCYoSCViij9gagtZV9Bg+vU=&se=1529928563&skn=testpolicy

Header 2:

Content-Type: application/json

But even though I have passed the correct Authorization value, I am getting the error below:

401:Invalid Authorization Token signature

解决方案

401:Invalid Authorization Token signature

According to the 401 error meanings that the token is not vaild.

Firstly please make sure that your policy has access to send the message.

Secondly, if you want to use the azure service bus Send Message Rest APi. The format should be following.

POST https://<yournamespace>.servicebus.windows.net/<yourentity>/messages
Authorization: SharedAccessSignature sr=https%3A%2F%2F<yournamespace>.servicebus.windows.net%2F<yourentity>&sig=<yoursignature from code above>&se=1438205742&skn=KeyName
ContentType: application/atom+xml;type=entry;charset=utf-8

We also could get more information about Service Bus access control with Shared Access Signatures from this article.

I also do a demo with postman. It works correctly on my side.

I use the following code to get the SAS token.

public static string GetSasToken(string resourceUri, string keyName, string key, TimeSpan ttl)
{
      var expiry = GetExpiry(ttl);
      string stringToSign = HttpUtility.UrlEncode(resourceUri) + "\n" + expiry;
      HMACSHA256 hmac = new HMACSHA256(Encoding.UTF8.GetBytes(key));
      var signature = Convert.ToBase64String(hmac.ComputeHash(Encoding.UTF8.GetBytes(stringToSign)));
      var sasToken = String.Format(CultureInfo.InvariantCulture, "SharedAccessSignature sr={0}&sig={1}&se={2}&skn={3}",
      HttpUtility.UrlEncode(resourceUri), HttpUtility.UrlEncode(signature), expiry, keyName);
      return sasToken;
}

private static string GetExpiry(TimeSpan ttl)
{
    TimeSpan expirySinceEpoch = DateTime.UtcNow - new DateTime(1970, 1, 1) + ttl;
    return Convert.ToString((int)expirySinceEpoch.TotalSeconds);
}
string queueUrl = "https://tomtestsb.servicebus.windows.net/" + "queue" + "/messages";
string token = GetSasToken(queueUrl,"Key", "value", TimeSpan.FromDays(1));

We could get the key and value with Azure portal

Test it with Postman.

Headers:

Authorization:SharedAccessSignature sr=https%3a%2f%2fyournamespace.servicebus.windows.net%2fqueuename%2fmessages&sig=SyumAUNnqWFjW2MqjwlomU%2fbblqZljq6LPJp3jpfU%2b4%3d&se=1529478623&skn=KeyName

Content-Type：application/xml

Body

<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">This is a message.</string>
