Description
Describe the bug
When sending a request with an XML body via POST
hc:send-request(
<hc:request href="http://localhost:8080/exist/apps/test/controller.xq"
method="POST" timeout="300">
<hc:body media-type="application/xml" method="xml">
<some>data</data>
</hc:body>
</hc:request>
)The content-type-header is set but content-length is absent.
This leads to request:get-data() to be empty, when such a request is received by any XQuery module in eXist-6.0.1.
In contrast a simple curl request
curl http://localhost:8080/exist/apps/test/ --data "<some>content</some>" -H "Content-Type:application/xml"does set the necessary header and therefore the body can be read.
Affected version: current stable (eXist-6.0.1)
This is fixed in 6.1.0 because request:get-data() does receive contents even if conent-length is absent
I was able to trace it down to the class org.expath.httpclient.impl.SinglePartRequestBody. In the setHeaders method only the content-type header is set. This is confirmed for XML-like payloads but judging from the source code it applies to any single body regardless of its type.
The source code I checked was decompiled from http-client-java-1.4.1.jar
Expected behavior
To either the content-length header to be set automatically or for users to be able to set it manually.
To Reproduce
-
create collection
/db/apps/test -
create resource
/db/apps/test/controller.xq
<request method="{request:get-method()}">
<headers>
{
for $h in request:get-header-names()
return <header name="{$h}">{ request:get-header($h) }</header>
}
</headers>
<body>{ request:get-data() }</body>
</request>- evaluate the code below in exide
hc:send-request(
<hc:request href="http://localhost:8080/exist/apps/test/controller.xq"
method="POST" timeout="300">
<hc:body media-type="application/xml" method="xml">
<some>data</data>
</hc:body>
</hc:request>
)- in the response the body element is empty
- call
curl http://localhost:8080/exist/apps/test/ --data "<some>content</some>" -H "Content-Type:application/xml" - in the response the body has the expected contents
