How to get Object from HttpResponse?
提问by Rami
I'm trying to send an object from server to client.
我正在尝试将对象从服务器发送到客户端。
client side:
客户端：
HttpResponse response = client.execute(request);
server side:
服务器端：
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws IOException
{
PrintWriter out = response.getWriter();
out.print(new Object());
}
How do I get the object from the response?
Do i need to use instead:

OutputStream out = response.getOutputStream();
if so which way is more efficient?

thanks.

You cant just send Object.toString() because it does not contain all information about the object.
Serialisation is probably what you need. Take a look at that: http://java.sun.com/developer/technicalArticles/Programming/serialization/
The Object you want to send has to implement Serializable.
On your server you can then use something like this:
您不能只发送 Object.toString()，因为它不包含有关对象的所有信息。序列化可能是您所需要的。看一看：http: //java.sun.com/developer/technicalArticles/Programming/serialization/
您要发送的对象必须实现可序列化。在您的服务器上，您可以使用以下内容：
OutputStream out = response.getOutputStream();
oos = new ObjectOutputStream(out);
oos.writeObject(yourSerializableObject);
On the client side you do:
在客户端，您执行以下操作：
in = new ObjectInputStream(response.getEntity().getContent()); //Android
in = new ObjectInputStream(response.getInputStream()); //Java
ObjcetClass obj = (ObjectClass)in.readObject();
