How to use curl to post xml data to a simple server

Question

I'm trying out go-restful. I found an example here: go example

I try to use curl to post data:

curl -H "Content-Type: text/xml"  -X POST -d "<Product><Id>1</Id><Title>The First</Title></Product>" localhost:8080/products

but it didn't work. My questions are:

how to use curl to post data in this example ?
how can this program read xml data into a struct using ?

err := req.ReadEntity(updatedProduct)

(In other examples, req.ReadEntity is able to read json data. How can this single function read data into different structs?)

thanks:)

I got the error message: 415: Unsupported Media Type. I thought this program allow us to post data:) — Casualet

This library doesnt recognize text/xml header for some reason, you should use application/xml

Check the source code

const (
    MIME_XML   = "application/xml"      
.....

Here is the difference rfc3023:

If an XML document -- that is, the unprocessed, source XML document -- is readable by casual users, text/xml is preferable to application/xml. MIME user agents (and web user agents) that do not have explicit support for text/xml will treat it as text/plain, for example, by displaying the XML MIME entity as plain text. Application/xml is preferable when the XML MIME entity is unreadable by casual users.
