How to read form parameters with helidon-se 4?

[sixwaaaay]

how to resolve http request form with content type of 'x-www-form-urlencoded' and 'multipart/form-data' ?

[romain-grecourt]

Form parameters can be processed like this:

Parameters parameters = request.content().as(Parameters.class);

E.g.

routing.post("/form-params", (req, res) -> {
    Parameters parameters = req.content().as(Parameters.class);
    res.send("value of 'foo': " + parameters.get("foo"));
})

---

Multipart can be processed like this:

MultiPart mp = req.content().as(MultiPart.class);

E.g.

routing.post("/multipart", (req, res) -> {
      MultiPart mp = req.content().as(MultiPart.class);
      while (mp.hasNext()) {
          ReadablePart part = mp.next();
          if ("file[]".equals(part.name())) {
              try (InputStream in = part.inputStream()) {
                  // ...
              } catch (IOException e) {
                  throw new RuntimeException("Failed to write content", e);
              }
          }
      }
  })
