问题描述
我有一个球衣客户端,我用来上传文件.我尝试在本地使用它,一切正常.但是在生产环境中我必须设置代理.我浏览了几页,但无法获得确切的解决方案.有人可以帮我解决这个问题吗?
Hi I've a jersey client which i use to upload a file. I tried using it locally and everything works fine. But in production environment i've to set proxy. I browsed thru few pages but could not get exact solution. Can someone pls help me with this?
这是我的客户端代码:
File file = new File("e:\test.zip");
FormDataMultiPart part = new FormDataMultiPart();
part.bodyPart(new FileDataBodyPart("file", file, MediaType.APPLICATION_OCTET_STREAM_TYPE));
WebResource resource = null;
if (proxy.equals("yes")) {
// How do i configure client in this case?
} else {
// this uses system proxy i guess
resource = Client.create().resource(url);
}
String response = (String) resource.type(MediaType.MULTIPART_FORM_DATA_TYPE).post(String.class, part);
System.out.println(response);
推荐答案
如果您想避免遗留项目中的更多库并且不需要代理身份验证,则有一个更简单的方法:
There is an easier approach, if you want to avoid more libraries in legacy projects and there is no need for Proxy Authentication:
首先你需要一个实现 HttpURLConnectionFactory
的类:
First you need a class which implements HttpURLConnectionFactory
:
import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.InetSocketAddress;
import java.net.Proxy;
import java.net.URL;
import com.sun.jersey.client.urlconnection.HttpURLConnectionFactory;
public class ConnectionFactory implements HttpURLConnectionFactory {
Proxy proxy;
private void initializeProxy() {
proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("myproxy.com", 3128));
}
public HttpURLConnection getHttpURLConnection(URL url) throws IOException {
initializeProxy();
return (HttpURLConnection) url.openConnection(proxy);
}
}
第二个是实例化一个com.sun.jersey.client.urlconnection.URLConnectionHandler
URLConnectionClientHandler ch = new URLConnectionClientHandler(new ConnectionFactory());
第三个是使用Client
构造函数代替Client.create
:
and third is to use the Client
Constructor instead of Client.create
:
Client client = new Client(ch);
当然你可以在ConnectionFactory
中自定义Proxy的初始化.
Of course you can customize the initializing of the Proxy in the ConnectionFactory
.
