Re: How to create Utilities method allow serizalization and deserialization request payload and response payload.

Thank you because the detail response.

I want to crawl data on a public website, I opened devtools and saw that it was written by GWT RPC.

This is the body of request I saw: 

7|0|10|https://a.b.c.d/e|5C6CDB13D0FD25B266F3C36FA7FF6ED9|a1.a2.a3.DataService|getCourseMembers|java.lang.Long/4227064769|java.lang.String/2004016611|java.util.List|20204524|java.util.Arrays$ArrayList/2507071751|20241|1|2|3|4|3|5|6|7|5|TXbrzIAAA|8|9|1|6|10|

As you can see, no problem with that syntax, I can understand roughly, I know the method is getCourseMembers. I want to build a function should return above body, like: 

                  public static String getBodyEncoded(String methodName, ... String methodBody ...) or something similar, and return the body above to send to server.

I also want to know the last past of request syntax:

                 1|2|3|4|1|5|6|7|7|8|7|9|7|10|7|11|7|12|7|13|7|14|

The next is the response body. This is really the problem. A response is very long, I put it in attached files.

I saw a JsonArray with more than 2000 elements, and I cannot understand what are they. The only thing I understand is the 2042nd element, it contains an unorder list. Maybe some elements before contains data about the order.

I want to build a method to extract/deserialize this response.

I am a newbie, if my question can be completed, can you guide me with more details, please?

Java is good, but other languages are acceptable, I still can deploy it.
