在逻辑应用程序中从服务总线获取内容 [英] Getting content from service bus in logic apps

问题描述

我是Azure逻辑应用程序的新手.我有一条服务总线，并将json对象消息传递到该服务总线，然后在逻辑应用程序中设置了一个操作来侦听我的服务总线.因此，每当一条新消息传入该服务总线时，我的逻辑应用程序就会将其提取，并将其发送到http.

I am new to Azure logic apps. I have a service bus and pass a json object message to that service bus then I set up an action in logic apps to listen to my service bus. So everytime a new message come in to that service bus my logic apps will pick it up and send it to http.

我的问题是如何从服务总线中的消息中获取属性并将其传递给我的http操作.我尝试过了

My question is how can I grab the property from the message in service bus and pass it to my http action. I tried this

"Id" : "@{json(triggerBody()[‘ContentData’]).id}"

但它不起作用

推荐答案

谁以及如何在队列中发送消息?

Who and how is sending the message on the queue?

我以这种方式读取json消息属性(DestinationPath):

I read a json message property (DestinationPath) in this way:

@{json(base64ToString(triggerBody()?['ContentData'])).DestinationPath}

这是我的逻辑应用程序的外观

Here is how my Logic App looks like

并且在我的情况下，消息是从Azure Web作业作为BrokeredMessage发送的:

and in my case the message is sent from an Azure webjob as a BrokeredMessage:

string jsonMessage = JsonConvert.SerializeObject(myObject);
Stream streamMessage = new MemoryStream(Encoding.UTF8.GetBytes(jsonMessage));
BrokeredMessage msg = new BrokeredMessage(streamMessage);

client.Send(msg);
