java - The type MultipartEntity is deprecated

Question

The documentation says the org.apache.http.entity.mime.MultipartEntity class is deprecated. Could anybody please suggest me an alternative ?

I am using this in my code like this:

entity.addPart("params", new StringBody("{"auth":{"key":""
            + authKey + ""},"template_id":"" + templateId + ""}"));
entity.addPart("my_file", new FileBody(image));
httppost.setEntity(entity);

If you read the docs carefully, you'll notice that you should use MultipartEntityBuilder as an alternative.

For example:

MultipartEntityBuilder builder = MultipartEntityBuilder.create();        

/* example for setting a HttpMultipartMode */
builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);

/* example for adding an image part */
FileBody fileBody = new FileBody(new File(image)); //image should be a String
builder.addPart("my_file", fileBody); 
//and so on

Note that there are several constructors for the FileBody class, by which you can provide mimeType, content type, etc.

After you're done with passing build instructions to the builder, you can get the built HttpEntity by invoking the MultipartEntityBuilder#build() method:

HttpEntity entity = builder.build();
