multipartform-data

I need to consume a request whose content-type is multipart/related. Request will consist of image, json payload and binary content. I tried to find some example on how to handle such request in a Spring boot application, I found some references on how to handle multipart/form-data request but nothing related to multipart/related mime type. Request is something like this: POST /upload Content-Type: multipart/related; boundary="123asdf234" --123asdf234 Content-Type: application/json; charset=UTF-8 Content-Disposition: form-data { "json": "payload" } —-123asdf234 Content-Type: application/zip

I have a Spring MVC application with a file upload form . I would like to be able to display validation errors to a user if the uploaded content is not valid (e.g. the content is not an image, etc.) However, by definition what is posted is of type: MultipartFile ( multipart/form-data ) and therefore I can't have a @ModelAttribute in my form and in order to use a BindingResult , it seems I do need a @ModelAttribute just before the BindingResult . My question is then, what is the most appropriate way of displaying validation errors to a user when all I have is a MultipartFile ? I could of course

I'm unable to approach the API that has been offered to me in the proper way for it to give me the response I'm looking for. I've been using Swift and Alamofire for a while but this is the first time I've to upload images using multipart/form-data. I'm able to upload images using Postman but I'm unable to get the same message send out by my application using the Alamofire framework. My Swift code: func postFulfilWish(wish_id: Int, picture : UIImage, completionHandler: ((AnyObject?, ErrorType?) -> Void)) { var urlPostFulfilWish = Constant.apiUrl; urlPostFulfilWish += "/wishes/";

I am trying to use HTTPClient object in C# to send a post request to an API. This is the CURL command: curl -X POST https://zzz.zzz.zzz/yyy -F Key=abcd -F media=@"audio.aac" I wrote the following code: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Net.Http; using System.IO; using System.Net.Http.Headers; namespace Speech2Text { class Program { static void Main(string[] args) { curl().Wait(); } static async Task curl() { var client = new HttpClient(); //Create List of KeyValuePairs List<KeyValuePair<string,

I'm developing an application where at a point the user has to choose any number of countries from a list and I must send the selected names through a multipart. I am not uploading any file along with the String[], but there is no route to upload information without it being a multipart and I don't have any saying in how the web server operates. I've attempted to simply send it as an Array, ArrayList and JsonArray as such: @Headers({ "Connection: Keep-Alive", }) @Multipart @PUT("/user/{id}") String updateUser(@Path("id") int userId, @Part("user[countries]") String[] countries); I've also

I have a webapp on a Tomcat server that allows files to be uploaded. There is a limit on the size of a file upload, and I'd like that limit to be enforced preemptively (ie, once you cross the limit, the file upload fails, rather than transferring the whole file, checking that it's too big and then sending an error). I tried to do this by add maxPostSize="1000" to the connector section in the relevant connector in server.xml, but I can still upload larger files. I've seen a post indicating that maxPostSize only works for a specific content type. So my question is whether what I'm doing is
