Question

我是android开发的新手。我需要了解如何在玻璃鱼服务器上将视频/音频文件部署为Web服务，然后从客户端设备（Mobile）调用Web服务。请帮助我获得非常基本的想法。我已经在服务器上运行了许多（简单）应用程序，并从客户端设备成功调用它们。这次需要调用音频/视频文件并将其放在我的客户端设备上。

谢谢

Answer 1

我已经在服务器上运行了许多（简单）应用程序并进行了调用他们成功地从客户端设备。

我不确定你在问什么。音频或视频文件的转换方式与其他所有文件相同。您遇到与转移“Hello World”字符串相同的挑战。

两个Webserver类是......

1-

package org.ali.javabrains.business;

import java.util.ArrayList;
import java.util.List;

public class BusinessProductImpl {

List<String> bookList= new ArrayList<String>();
List<String> moviesList= new ArrayList<String>();
List<String> musicList= new ArrayList<String>();

public BusinessProductImpl(){

    bookList.add("swatnama");
    bookList.add("yadona");
    bookList.add("ka ta raghali za ba gul sham");

    musicList.add ("hamayun album1");
    musicList.add ("bkhtayar Khatak");
    musicList.add ("zare sandary");

    moviesList.add("bajrangi bhai jan");
    moviesList.add("Terminator 2");
    moviesList.add("Salam Namasty");
}

public List<String> getProductCategories(){

List<String> categories=new ArrayList<>();
categories.add("books");
categories.add("Movies");
categories.add("Music");
return categories;
}

public List<String> getProducts(String category){
    switch (category.toLowerCase()) {
    case "books":
        return bookList;
    case "music":
        return musicList;
    case "movies":
        return moviesList;
    }
        return null;
    }
public boolean addProduct(String category, String product){

    switch (category.toLowerCase()) {
    case "books":
        bookList.add(product);
        break;
    case "music":
        musicList.add(product);
        break;
    case "movies":
        moviesList.add(product);
        break;
    default:
        return false;
    }
        return true;
}

}

2- .....

package org.ali.javabrains;

import java.util.List;
import org.ali.javabrains.business.BusinessProductImpl;
import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService
public class ProductCatalog {

BusinessProductImpl BpImpl=new BusinessProductImpl();
@WebMethod
public List<String> getProductCategories(){
return BpImpl.getProductCategories();
}

@WebMethod
public List<String> getProducts(String category){
    return BpImpl.getProducts(category);
}
public boolean addProduct(String category, String product){
    return BpImpl.addProduct(category, product);
}

public int addnumbers(int a, int b){
    return (a+b);
}
public int minusnumbers(int a, int b){
    return (a-b);
}
}
