public class MultipartRequestEntity extends Object implements RequestEntity
The HTTP multipart POST method is defined in section 3.3 of RFC1867:
The media-type multipart/form-data follows the rules of all multipart MIME data streams as outlined in RFC 1521. The multipart/form-data contains a series of parts. Each part is expected to contain a content-disposition header where the value is "form-data" and a name attribute specifies the field name within the form, e.g., 'content-disposition: form-data; name="xxxxx"', where xxxxx is the field name corresponding to that field. Field names originally in non-ASCII character sets may be encoded using the method outlined in RFC 1522.
This entity is designed to be used in conjunction with the
post method to provide
multipart posts. Example usage:
File f = new File("/path/fileToUpload.txt");
PostMethod filePost = new PostMethod("http://host/some_path");
Part[] parts = {
new StringPart("param_name", "value"),
new FilePart(f.getName(), f)
};
filePost.setRequestEntity(
new MultipartRequestEntity(parts, filePost.getParams())
);
HttpClient client = new HttpClient();
int status = client.executeMethod(filePost);
