I'm trying to write a restful web service in java that will take a few string params and a binary file (pdf) param.
I understand how to do the strings but I'm getting hung up on the binary file. Any ideas / examples?
Here's what I have so far
@GET
@ConsumeMime("multipart/form-data")
@ProduceMime("text/plain")
@Path("submit/{client_id}/{doc_id}/{html}/{password}")
public Response submit(@PathParam("client_id") String clientID,
@PathParam("doc_id") String docID,
@PathParam("html") String html,
@PathParam("password") String password,
@PathParam("pdf") File pdf) {
return Response.ok("true").build();
}
Since I've posted this the link that had the answer has been removed, so here is my implementation.
@POST
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces(MediaType.TEXT_PLAIN)
@Path("submit")
public Response submit(@FormDataParam("clientID") String clientID,
@FormDataParam("html") String html,
@FormDataParam("pdf") InputStream pdfStream) {
try {
byte[] pdfByteArray = DocUtils.convertInputStreamToByteArrary(pdfStream);
} catch (Exception ex) {
return Response.status(600).entity(ex.getMessage()).build();
}
}
...
public static byte[] convertInputStreamToByteArrary(InputStream in) throws IOException {
ByteArrayOutputStream out = new ByteArrayOutputStream();
final int BUF_SIZE = 1024;
byte[] buffer = new byte[BUF_SIZE];
int bytesRead = -1;
while ((bytesRead = in.read(buffer)) > -1) {
out.write(buffer, 0, bytesRead);
}
in.close();
byte[] byteArray = out.toByteArray();
return byteArray;
}
First, set the body to "binary": Select "binary" to have Postman send binary data. Now click "Select File" in Postman to attach a file: Attach a file to upload with the "Select File" button.
File format. A PDF file is organized using ASCII characters, except for certain elements that may have binary content. The file starts with a header containing a magic number (as a readable string) and the version of the format, for example %PDF-1.7 .
PDF files are either 8-bit binary files or 7-bit ASCII text files (using ASCII-85 encoding). Every line in a PDF can contain up to 255 characters.

try {

byte[] buffer = new byte[BUF_SIZE];
int bytesRead = -1;
while ((bytesRead = in.read(buffer)) > -1) {
out.write(buffer, 0, bytesRead);
}
in.close();
byte[] byteArray = out.toByteArray();
return byteArray;
}
