Http-request - new question

[Trying_to_learn]

Although I'm getting nowhere fast with the other stuff WRT this node.....

When the node is open:

I'm confused. (What's new?)

So the way I've been using it is the URL is FIXED.

But looking at the docs (part of picture) it is confusing for me.

I change thepayload from Ignore to send as request body......
I'm not sure what that means.

But I'd like to be able to know if I can change the URL depending on what msg.payload it is sent.

The docs don't really say it, but the wording:
Sent as the body of the request.
What does that really mean?

Sorry folks.

Thanks in advance.

Sent as the body of the request.

You need to understand HTTP APIs to understand that. In basic terms, a GET pretty much does NOT use the payload, whereas a PUT or POST might use the payload.

But I'd like to be able to know if I can change the URL depending on what msg.payload it is sent.

The help states:

When configured within the node, the URL property can contain mustache-style tags. These allow the url to be constructed using values of the incoming message. For example, if the url is set to example.com/{{{topic}}} , it will have the value of msg.topic automatically inserted. Using {{{...}}} prevents mustache from escaping characters like / & etc.

So you could have a URL of https://something/category/{{{payload}}}

Equally, you could leave it blank and use a change or function node to build msg.url from msg.payload

To set the url of the request, you can pass in msg.url - as long as you leave the url field in the node configuration blank.

Ah!

Yeah. Thanks.

Silly me. I somehow didn't parse that correctly.

Though - of course - changing the URL probably isn't a good idea but it was just a bit confusing.
