Consider adding a progress listener for Callback #80
Description
From #26
One thing that would make this library even better is to add a simple progress callback that updates as a request is made. For POST/PUT/PATCH etc it would be great for this to monitor upload progress, and for GET/DELETE etc it would be great for download progress. Thoughts? This is another side note, but it would be nice to include a default callback class that provides stubbed implementations of the callback interface for those who don't wish to provide functionality for some of the methods.
Future<HttpResponse<JsonNode>> future = Unirest.post("http://httpbin.org/post")
.header("accept", "application/json")
.field("param1", "value1")
.field("param2", "value2")
.asJsonAsync(new Callback<JsonNode>() {
public void failed(UnirestException e) {
System.out.println("The request has failed");
}
public void completed(HttpResponse<JsonNode> response) {
int code = response.getCode();
Map<String, String> headers = response.getHeaders();
JsonNode body = response.getBody();
InputStream rawBody = response.getRawBody();
}
public void cancelled() {
System.out.println("The request has been cancelled");
}
public void progress(long current, long total) {
System.out.println("Progress: " + ((float)current / (float)total));
}
});
