Azure Logic应用-获取Blob内容-设置内容类型 [英] Azure Logic Apps - Get Blob Content - Setting Content type

问题描述

Azure Logic Apps操作获取Blob内容"不允许我们设置返回内容类型.

The Azure Logic Apps action "Get Blob Content" doesn't allow us to set the return content-type.

默认情况下，它将blob作为二进制(八位字节流)返回，这在大多数情况下是没有用的.通常，拥有文本(例如json，xml，csv等)会很有用.

By default, it returns the blob as binary (octet-stream), which is useless in most cases. In general it would be useful to have text (e.g. json, xml, csv, etc.).

我知道该操作处于beta状态.这是短期路线图吗?

I know the action is in beta. Is that on the short term roadmap?

推荐答案

在对Logic Apps进行了很多摆弄之后，我终于了解了发生了什么.

After fiddling much with Logic Apps, I finally understood what was going on.

HTTP请求的JSON输出是XML有效负载的JSON表示形式:

The JSON output from the HTTP request is the JSON representation of an XML payload:

{
  "$content-type": "application/xml",
  "$content": "77u/PD94bWwgdm..."
}

因此我们可以对其进行解码，但是实际上它是没有用的.这是Logic App的XML对象.我们可以对其应用xml函数，例如xpath.

So we can decode it, but it is useless really. That is an XML object for Logic App. We can apply xml functions to it, such as xpath.
