Send Byte array as file in using http client in java

Question

We have byte array of file and we want to upload it as file. FileBody only gets File as parameter but we have a array of bytes.

One solution is to save byte array into file and then send it but it is not appropriate for me.

byte b[]= new byte[1000];
//fill b
MultipartEntity form = new MultipartEntity();
form.addPart("file", new FileBody(/* b? */));

thanks.

Answer 1

You can do something like

HttpClient client=null;
byte b[]= new byte[1000];
MultipartEntity form = new MultipartEntity();
ContentBody cd = new InputStreamBody(new ByteArrayInputStream(b), "my-file.txt");
form.addPart("file", cd);

HttpEntityEnclosingRequestBase post = new HttpPost("");//If a PUT request then `new HttpPut("");`
post.setEntity(form);
client.execute(post);

Answer 2

You can use ByteArrayBody instead InputStreamBody or FileBody.

HttpClient client=null;
byte b[]= new byte[1000];
MultipartEntity form = new MultipartEntity();
ContentBody cd = new ByteArrayBody(b, "my-file.txt");
form.addPart("file", cd);

HttpEntityEnclosingRequestBase post = new HttpPost("");
post.setEntity(form);
client.execute(post);
