postman - 如何在 Postman 中创建 SAS token 以与服务总线一起使用？

Question

基于此 Microsoft 文档: https://learn.microsoft.com/en-us/rest/api/eventhub/generate-sas-token

nodejs 的代码是:

function createSharedAccessToken(uri, saName, saKey) { 
if (!uri || !saName || !saKey) { 
        throw "Missing required parameter"; 
    } 
var encoded = encodeURIComponent(uri); 
var now = new Date(); 
var week = 60*60*24*7;
var ttl = Math.round(now.getTime() / 1000) + week;
var signature = encoded + '\n' + ttl; 
var signatureUTF8 = utf8.encode(signature); 
var hash = crypto.createHmac('sha256', saKey).update(signatureUTF8).digest('base64'); 
return 'SharedAccessSignature sr=' + encoded + '&sig=' +  
    encodeURIComponent(hash) + '&se=' + ttl + '&skn=' + saName; 
 }

我在 Postman 上尝试过，以防有人需要帮助。这是使用 Postman 在预请求脚本下为我工作的代码

var namespace = pm.collectionVariables.get("serviceNamespace");
var uri = "https://" + namespace + ".servicebus.windows.net/adfTest/messages";
var saName = pm.collectionVariables.get("SharedAccessKeyName");
var saKey = pm.collectionVariables.get("SharedAccessKeySend");

var sasToken = createSharedAccessToken(uri, saName, saKey);

console.log(sasToken);
pm.collectionVariables.set("SasToken", sasToken);

function createSharedAccessToken(uri, saName, saKey) { 
    if (!uri || !saName || !saKey) { 
            throw "Missing required parameter"; 
        } 
    var encoded = encodeURIComponent(uri).toLowerCase(); 
    var now = new Date(); 
    var week = 60*60*24*7;
    var ttl = Math.round(now.getTime() / 1000) + week;
    var signature = encoded + '\n' + ttl;     
    var hash = CryptoJS.HmacSHA256(signature, saKey);
    var hashInBase64 = CryptoJS.enc.Base64.stringify(hash);
    return 'SharedAccessSignature sr=' + encoded + '&sig=' +  
        encodeURIComponent(hashInBase64) + '&se=' + ttl + '&skn=' + saName; 
}

1. 在您的集合下创建变量:

从 Azure 门户获取值 - 服务总线服务命名空间、SharedAccessKey、SharedAccessKeyName

1. 在Pre-request Script下添加代码

   var namespace =      pm.collectionVariables.get("serviceNamespace");
   var uri = "https://" + namespace + ".servicebus.windows.net/adfTest/messages";
   var saName = pm.collectionVariables.get("SharedAccessKeyName");
   var saKey = pm.collectionVariables.get("SharedAccessKeySend");
   
   var sasToken = createSharedAccessToken(uri, saName, saKey);
   
   console.log(sasToken);
   pm.collectionVariables.set("SasToken", sasToken);
   
   function createSharedAccessToken(uri, saName, saKey) { 
       if (!uri || !saName || !saKey) { 
               throw "Missing required parameter"; 
           } 
       var encoded = encodeURIComponent(uri).toLowerCase(); 
       var now = new Date(); 
       var week = 60*60*24*7;
       var ttl = Math.round(now.getTime() / 1000) + week;
       var signature = encoded + '\n' + ttl;     
       var hash = CryptoJS.HmacSHA256(signature, saKey);
       var hashInBase64 = CryptoJS.enc.Base64.stringify(hash);
       return 'SharedAccessSignature sr=' + encoded + '&sig=' +  
           encodeURIComponent(hashInBase64) + '&se=' + ttl + '&skn=' + saName; 
   }
   

注意:adfTest部分为主题名称，应替换为您的主题名称

var uri = "https://" + namespace + ".servicebus.windows.net/adfTest/messages";

• 在授权下使用 sasToken 变量:

• 从下拉菜单中选择 API key 。

• key =授权

• Value = {{SasToken}} <-- 这是变量名

• 添加到 = 标题

1. 创建帖子:

这些是职位的要求

     POST https://<yournamespace>.servicebus.windows.net/<yourentity>/messages
    Content-Type: application/json
    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

URL 应如下所示:https://.servicebus.windows.net//消息

在授权下从父级继承授权:

这将在集合下添加带有预请求脚本生成的 SAS token 的授权 header

添加其他标题:

1. 将消息放在正文中:

这可以是任何 json 数据
