Looking for help to read file content from multipart response?

[Sajan Soosaimicheal]

Hello All,

looking for help to get file content from multipart file upload "requestBody".  not sure how to read from "requestBody". please share if have any example.

@POST @Consumes(MediaType.MULTIPART_FORM_DATA) @Produces(MediaType.TEXT_PLAIN) public String echo(String requestBody) throws Exception { return requestBody; }

This worked for us (single-file)...

File Upload (Multipart Form):

@Schema(description = "Single file upload")

public class FileUpload {

    @FormParam("file")

    @PartType(APPLICATION_OCTET_STREAM)

    public File data;

    @FormParam("filename")

    @PartType(TEXT_PLAIN)

    public String fileName;

    @FormParam("path")

    @PartType(TEXT_PLAIN)

    public String path;

    @FormParam("mimetype")

    @PartType(TEXT_PLAIN)

    public String mimeType;

}

File Upload (REST resource):

/**

 * Upload a file

 */

@POST

@Path("/upload")

@Consumes(MULTIPART_FORM_DATA)

@RequestBody(

    content = @Content(

        mediaType = MULTIPART_FORM_DATA,

        schema = @Schema(implementation = FileUpload.class)))

@Operation(summary = "Upload file")

public Uni<Response> upload(@MultipartForm final FileUpload request, final @BeanParam ProjectParams params) throws Exception {

}

Resource Test:

given().pathParam("client", "my-client")

        .pathParam("project", "my-project")

        .multiPart("file", readFile().toFile())

        .multiPart("path", "a/b")

        .multiPart("filename", "sample1.txt")

        .multiPart("mimetype", "text/plain")

        .when()

        .post("/s3/storage/{client}/{project}")

        .then()

        .statusCode(CREATED.getStatusCode());

thanks @KimJohn. we are creating Rest API using quarks and it's not reactive.
