Curl -xget works, but fail when use RESTful client in java

Elastic Stack Elasticsearch
1

I tried to send http/get to my elasticsearch server.if I query:

    curl 'http://localhost:9200/index/_search?scroll=1m&size=50&pretty'

-d '{"query" : {"match_all" : {}}}'

it works perfect. But when I tried to use jersy to build my client, I did
the follwoing:

    public class JerseyClientGet {

         public static void main(String[] args) {
   
             Client client = Client.create();
             WebResource webResource = client

.resource("http://localhost:9200/index/_search?scroll=1m&size=50 -d
'{"query" : {"match_all" : {}}}'");
......
}
}

And I got these error message:

     java.lang.IllegalArgumentException: Illegal character in query at

index 52: http://localhost:9200/obd2/_search?scroll=1m&size=50 -d '{"query"

... 2 more

The "-d" seems to be an illegal character?
Anyone knows what's the problem with my format?
PS: I can use java API to query, just use this RESTful for some test.

Updated.
I figured out that I need to do url-encode to process some characters like
{ , } ," ...
so I change part my code to:

String string1="-d {"query" : {"match_all" : {}}}";
WebResource webResource = client
.resource("http://localhost:9200/obd2/_search?scroll=1m&size=50"+
URLEncoder.encode(string1));

Now I get the respones:

            java.lang.RuntimeException: Failed : HTTP error code : 400

Is that mean my get/request was successfully sent to the server.
The new error was triggered by some other reasons such as firewall...etc

Well, the curl command uses the -d option to specify the content data to
pass to the server. It is not part of the URL. Your mistake is trying to
take a curl command-line and treat the entire thing as a URL, when in fact
the URL is only part of the request.

I don't know how the JerseyGetClient works, but here is one example I found
that might help, or at least provide a starting point.

The idea is that a typical HTTP request in Java accepts the URL at one
string, or perhaps even two strings (the server/port, and then the URI
path), and then the content type and data as separately specified values
elsewhere in the API.

Got the answer!

It turns out that just add an "&" between the url and encoded json body.

String string1="{"query" : {"match_all" : {}}}";
WebResource webResource = client
.resource("http://localhost:9200/obd2/_search?scroll=1m&size=50&"+
URLEncoder.encode(string1));

then the http/get was successfully transferred and return the query result.
