Class MultiPartContentProvider

java.lang.Object

org.eclipse.jetty.client.util.AbstractTypedContentProvider

org.eclipse.jetty.client.util.MultiPartContentProvider

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable, java.lang.Iterable<java.nio.ByteBuffer>, ContentProvider, ContentProvider.Typed, AsyncContentProvider

public class MultiPartContentProvider
extends AbstractTypedContentProvider
implements AsyncContentProvider, java.io.Closeable

A ContentProvider for form uploads with the "multipart/form-data" content type.

Example usage:

 MultiPartContentProvider multiPart = new MultiPartContentProvider();
 multiPart.addFieldPart("field", new StringContentProvider("foo"), null);
 multiPart.addFilePart("icon", "img.png", new PathContentProvider(Paths.get("/tmp/img.png")), null);
 multiPart.close();
 ContentResponse response = client.newRequest("localhost", connector.getLocalPort())
         .method(HttpMethod.POST)
         .content(multiPart)
         .send();
 

The above example would be the equivalent of submitting this form:

 <form method="POST" enctype="multipart/form-data"  accept-charset="UTF-8">
     <input type="text" name="field" value="foo" />
     <input type="file" name="icon" />
 </form>
