These "parts" are essentially embedded HTTP requests; the lines under each listed GET/PUT/etc are headers for that embedded request. Here is the structure of their example annotated:
POST /batch/farm/v1 HTTP/1.1 # actual request and headers Authorization: Bearer your_auth_token Host: www.googleapis.com Content-Type: multipart/mixed; boundary=batch_foobarbaz Content-Length: total_content_length # rest is actual request content --batch_foobarbaz # first multipart segment Content-Type: application/http # multipart segment headers Content-ID: <item1:[email protected]> GET /farm/v1/animals/pony # multipart segment *content* --batch_foobarbaz # second multipart segment Content-Type: application/http # multipart segment headers Content-ID: <item2:[email protected]> PUT /farm/v1/animals/sheep # multipart segment *content* Content-Type: application/json Content-Length: part_content_length If-Match: "etag/sheep" { "animalName": "sheep", "animalAge": "5" "peltColor": "green", } --batch_foobarbaz # third multipart segment Content-Type: application/http # multipart segment headers Content-ID: <item3:[email protected]> GET /farm/v1/animals # multipart segment *content* If-None-Match: "etag/animals" --batch_foobarbaz-- As noted the part where the part_content_length is is inside the content for one of the multipart segments. Mojolicious doesn't have anything to deal with the content of multipart segments of this type, so you need to construct them yourself, but you could maybe leverage Mojolicious's existing ability to construct such HTTP requests. my $embedded_tx = $ua->build_tx(PUT => '/farm/v1/animals/sheep', {'If-Match' => 'etag/sheep'}, json => $sheep_data); ... my $multipart_tx = $ua->post('/batch/farm/v1' => $headers => multipart => [ {content => $embedded_tx->req->to_string, 'Content-Type' => 'application/http'}, ... ]); Hope that helps, -Dan On Tue, Sep 18, 2018 at 12:50 PM Steve Dondley <[email protected]> wrote: > I'm starting a new thread related to the previous one regarding making a > batch api request to Google's API.
