如何从HttpResponse获取Object？ [英] How to get Object from HttpResponse?

问题描述

我正在尝试从服务器向客户端发送对象。

I'm trying to send an object from server to client.

客户端：

HttpResponse response = client.execute(request);

服务器端：

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws  IOException 
{
    PrintWriter out = response.getWriter();
    out.print(new Object());
}

如何从响应中获取对象？

我是否需要使用：

How do I get the object from the response?
Do i need to use instead:

OutputStream out = response.getOutputStream();

如果这样哪种方式更有效？

示例代码请：）< br>
谢谢。

if so which way is more efficient?
example code please :)
thanks.

推荐答案

您无法发送Object.toString（），因为它不包含有关该对象的所有信息。
序列化可能就是你所需要的。请看一下： http://java.sun.com/developer/technicalArticles/编程/序列化/

您要发送的对象必须实现Serializable。
在您的服务器上，您可以使用以下内容：

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:

OutputStream out = response.getOutputStream();
oos = new ObjectOutputStream(out);
oos.writeObject(yourSerializableObject);

在客户端，您可以：

in = new ObjectInputStream(response.getEntity().getContent()); //Android
in = new ObjectInputStream(response.getInputStream()); //Java
ObjcetClass obj = (ObjectClass)in.readObject();
