I have finally got a workaround for it. I will be using javax mail MimeMultipart. Below is a code snipped for the solution:- ByteArrayDataSource datasource = new ByteArrayDataSource(in, “multipart/form-data”); MimeMultipart multipart = new MimeMultipart(datasource); int count = multipart.getCount(); log.debug(“count ” + count); for (int i = 0; i < count; i++) { BodyPart bodyPart = … Read more
Well, note that the request contains binary data, so I’m not posting the request as such – instead, I’ve converted every non-printable-ascii character into a dot (“.”). POST /cgi-bin/qtest HTTP/1.1 Host: aram User-Agent: Mozilla/5.0 Gecko/2009042316 Firefox/3.0.10 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive Referer: http://aram/~martind/banner.htm Content-Type: multipart/form-data; boundary=2a8ae6ad-f4ad-4d9a-a92c-6d217011fe0f Content-Length: 514 … Read more
This answer extends yurin’s answer. The issue he brought up was that the content of a MimeMultipart may itself be another MimeMultipart. The getTextFromMimeMultipart() method below recurses in such cases on the content until the message body has been fully parsed. private String getTextFromMessage(Message message) throws MessagingException, IOException { String result = “”; if (message.isMimeType(“text/plain”)) … Read more
You can try the following sample code. In this demo app, we will upload a photo after selecting from the Gallery. Hope it helps! build.gradle file: dependencies { … compile ‘com.squareup.retrofit2:retrofit:2.0.1’ compile ‘com.squareup.retrofit2:converter-gson:2.0.1’ … } WebAPIService.java file: public interface WebAPIService { @Multipart @POST(“/api/fileupload”) Call<ResponseBody> postFile(@Part MultipartBody.Part file, @Part(“description”) RequestBody description); } FileActivity.java file: … import … Read more
Here’s some sample code. In short, you’ll need to use the mime/multipart package to build the form. package main import ( “bytes” “fmt” “io” “mime/multipart” “net/http” “net/http/httptest” “net/http/httputil” “os” “strings” ) func main() { var client *http.Client var remoteURL string { //setup a mocked http client. ts := httptest.NewTLSServer(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) { b, err … Read more
Use MultipartRequest class Upload(File imageFile) async { var stream = new http.ByteStream(DelegatingStream.typed(imageFile.openRead())); var length = await imageFile.length(); var uri = Uri.parse(uploadURL); var request = new http.MultipartRequest(“POST”, uri); var multipartFile = new http.MultipartFile(‘file’, stream, length, filename: basename(imageFile.path)); //contentType: new MediaType(‘image’, ‘png’)); request.files.add(multipartFile); var response = await request.send(); print(response.statusCode); response.stream.transform(utf8.decoder).listen((value) { print(value); }); } name spaces: import … Read more

I’ve tested it, with a home-made server and a simple response. Not sure if the response is well-formed because no browser understands it 100% OK. But here are the results: Firefox 67.0.1 (64-bit): Renders only the last part, others are ignored. IE 11.503: Saves all the content in a single file (including the boundaries), nothing … Read more
EDIT: I am maintaining a similar, but more in-depth answer at: https://stackoverflow.com/a/28380690/895245 To see exactly what is happening, use nc -l or an ECHO server and an user agent like a browser or cURL. Save the form to an .html file: <form action=”http://localhost:8000″ method=”post” enctype=”multipart/form-data”> <p><input type=”text” name=”text” value=”text default”> <p><input type=”file” name=”file1″> <p><input type=”file” … Read more
That’s only possible with the XHR FormData API (previously known being part of as “XHR2” or “XHR Level 2”, currently known as “XHR Advanced Features”). Given this HTML, <input type=”file” id=”myFileField” name=”myFile” /> you can upload it as below: var formData = new FormData(); formData.append(“myFile”, document.getElementById(“myFileField”).files[0]); var xhr = new XMLHttpRequest(); xhr.open(“POST”, “myServletUrl”); xhr.send(formData); XHR … Read more
