Hi, Florent:
I'm wondering whether a CRLF is required before the initial boundary. That
seems to be implied but not explicitly stated by:
https://www.w3.org/Protocols/rfc1341/7_2_Multipart.html
A couple of suggestions for investigating:
* Confirm that the constructed multipart/mixed is parseable using
xdmp.multipartDecode()
https://docs.marklogic.com/xdmp.multipartDecode
* Write the two documents individually, read both document back in a single
request that accepts multipart/mixed, and compare the REST API response to the
constructed multipart/mixed
https://docs.marklogic.com/REST/GET/v1/documents
If that doesn't discover the issue, maybe setting the content-length in the
part might help (though the standard explicitly requires no headers in the
part).
Hoping that's useful,
Erik Hennum

Subject: Re: [MarkLogic Dev General] Client API - 8000 - POST /v1/documents -
Unexpected 400
Hi,
Actually, I made a mistake in the Content-Type of the overall request, I used
"multipart/related" instead of "multipart/mixed" as mentioned in the doc. But
when I fix it, I get a 500 with the following error message:
XDMP-AS: (err:XPTY0004) $meta-type as xs:string -- Invalid coercion: () as
xs:string . See the MarkLogic server error log for further detail.
It seems it all goes down to $content-type being the empty sequence in the
following call in document-model-update.xqy (in ML 9.0-1.1):
let $document-next :=
if ($part-type ne "document-metadata") then ()
else docmodupd:parse-metadata-map($curr-uri,$content-type,$body)
But then, it is beyond my knowledge...
Regards,

Hi,
I am trying to use the POST /v1/documents endpoint on 8000 to insert several
documents at once. From the chapter "Reading and Writing Multiple Documents"
in the REST Guide, in section "Specifying an Explicit Document URI" [1], the
following pseudo header in each part should be enough to set the URI for each
document:
Content-Disposition: attachment;filename=/your/uri
But I get a 400 with the message: "REST-REQUIREDPARAM: (err:FOER0000) Required
parameter: missing required extension parameter".
Any idea why?

Below a complete repro that can be played in QConsole (and later an example
using PUT instead, which does work):
'use strict';
const rn = '\r\n';
const bnd = '.ml.rockzzz.';
var body = rn;
// first part
body += '--' + bnd + rn;
body += 'Content-Type: application/json' + rn;
body += 'Content-Disposition: attachment; filename="/test/multi-one.json"' + rn;
body += rn;
body += JSON.stringify({ hello: 'one!' });
body += rn;
// second part
body += '--' + bnd + rn;
body += 'Content-Type: application/json' + rn;
body += 'Content-Disposition: attachment; filename="/test/multi-two.json"' + rn;
body += rn;
body += JSON.stringify({ hello: 'two!' });
body += rn;
// after the last part
body += '--' + bnd + '--' + rn;
xdmp.httpPost(
'http://localhost:8000/v1/documents', {
authentication : {
method : 'digest',
username : 'admin',
password : 'admin'
},
headers: {
"Content-type": 'multipart/related; boundary=' + bnd,
Accept: "application/json"
},
data: body
});
Here is the example using PUT, and indeed working fine:
'use strict';
xdmp.httpPut(
'http://localhost:8000/v1/documents?uri=/test/single.json', {
authentication : {
method : 'digest',
username : 'admin',
password : 'admin'
},
headers: {
"Content-type": 'application/json',
Accept: "application/json"
},
data: JSON.stringify({ hello: 'world!' })
});
Any idea what I did wrong?
