Any example of multipart post?

[elasmojs]

Hi, Thanks to ureq, have achieved what I wanted to a large extent in my project. Is there any multipart suppor/example right now?

[algesten]

@elasmojs there isn't any built in support for multipart forms. Constructing the multipart is easy enough though – I was briefly looking through crates.io, but can't find a framework agnostic impl. Could be I didn't look hard enough, or that that someone really ought to build a generic multipart builder.

I think the API should look something like this:

let multi = MultipartBuilder::new()
  .addText("Some text") // Content-Disposition: form-data; name="text"
  .addFile("myfile.txt") // Content-Disposition: form-data; name="file1"; filename="myfile.txt"
  .build().unwrap(); // delay io errors to here

let res = ureq::post("https://my-fine.server")
  .set("content-length", multi.len())
  .set("content-type", multi.content_type()) // multipart/form-data; boundary=----90519140972754266
  .send(multi.into_reader());

@algesten , thank you for the response. I have solved this by using https://crates.io/crates/multipart

@elasmojs can you provide an example, please?
I'm not so familiar with web stuff, so I ended up switching to reqwest since it supports multipart forms out of the box. Just curious how it can be achieved with ureq + multipart.

I came across this too, and also implemented it myself.

To aid any future visitors, I have written up a gist which should serve as a good template:

i implemented a multipart toolkit for ureq:
ureq_multipart

usage:

`
use ureq_multipart::MultipartBuilder;

let (content_type,data) = MultipartBuilder::new()
.add_file("test","/home/feiy/Desktop/1.txt").unwrap()
.finish().unwrap();
let resp: Value = req
.post(&service_url)
.set("Content-Type", &content_type)
.send_bytes(&data)?
.into_json()?
`

i have public ureq_multipart 1.1 ,add ureq request send multipart method:

use ureq_multipart::MultipartRequest;

let resp: Value = req
            .post(&service_url)
            .send_multipart_file("name","&/home/feiy/Desktop/1.txt")?
            .into_json()?

FYI, the multipart crate is unmaintained: https://rustsec.org/advisories/RUSTSEC-2023-0050.html

I'd love to see ureq to gain builtin support for multipart so we don't need to depend on an unmaintained crate.
