HttpClient4 Post XML到一个服务器上
现在网上介绍的HttpClient基本上全是3.x版本的内容，HttpClient4的API变化相对3已经变化很大，对HttpClient4做了简单的研究后，香港虚拟主机，完成了一个HttpClient4 Post XML功能。
对于POST方式，最先想到的就是表单提交了，POST XML自然想到的就是定义一个变量名，服务器空间，比如叫xmldata，然后将这个参数的值POST出去，网站空间，在服务端接收的时候，自然也是通过 requset.getParameter(“xmldata”)方式来接收。
现在我在这里要做的不是通过上面的方式，而是不指定参数名来Post，实际上就是将一个流写入请求。
下面是具体的实现方式：
1、参数名方式POST XML数据
import org.apache.http.*; import org.apache.http.client.entity.UrlEncodedFormEntity; import org.apache.http.client.methods.HttpPost; import org.apache.http.impl.client.DefaultHttpClient; import org.apache.http.message.BasicNameValuePair; import org.apache.http.client.*; import java.io.IOException; import java.io.InputStreamReader; import java.io.UnsupportedEncodingException; import java.util.*; /** * 通过指定参数名的方式POST XML * * @author leizhimin 2010-7-8 22:29:28 */ public class TestPost { public static void main(String[] args) throws IOException { HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost(“http://localhost:8080/waitsrv/GenXmlServlet”); List<NameValuePair> formparams = new ArrayList<NameValuePair>(); formparams.add(new BasicNameValuePair(“xmldate”, “<html>你好啊啊</html>”)); formparams.add(new BasicNameValuePair(“info”, “xxxxxxxxx”)); UrlEncodedFormEntity entity = new UrlEncodedFormEntity(formparams, “GBK”); //entity.setContentType(“text/xml; charset=GBK”); httppost.setEntity(entity); HttpResponse response = httpclient.execute(httppost); HttpEntity resEntity = response.getEntity(); InputStreamReader reader = new InputStreamReader(resEntity.getContent(), “ISO-8859-1”); char[] buff = new char[1024]; int length = 0; while ((length = reader.read(buff)) != -1) { System.out.println(new String(buff, 0, length)); httpclient.getConnectionManager().shutdown(); } } }
2、不指定参数名的方式来POST数据
import org.apache.http.HttpEntity; import org.apache.http.HttpResponse; import org.apache.http.NameValuePair; import org.apache.http.client.HttpClient; import org.apache.http.client.entity.UrlEncodedFormEntity; import org.apache.http.client.methods.HttpPost; import org.apache.http.impl.client.DefaultHttpClient; import org.apache.http.message.BasicNameValuePair; import org.apache.http.entity.*; import java.io.IOException; import java.io.InputStreamReader; import java.util.ArrayList; import java.util.List; /** * 不指定参数名的方式来POST数据 * * @author leizhimin 2010-7-8 3:22:53 */ public class TestPostXml { public static void main(String[] args) throws IOException { HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost(“http://localhost:8080/waitsrv/GenXmlServlet”); StringEntity myEntity = new StringEntity(“<html>你好啊啊</html>”, “GBK”); httppost.addHeader(“Content-Type”, “text/xml”); httppost.setEntity(myEntity); HttpResponse response = httpclient.execute(httppost); HttpEntity resEntity = response.getEntity(); InputStreamReader reader = new InputStreamReader(resEntity.getContent(), “ISO-8859-1”); char[] buff = new char[1024]; int length = 0; while ((length = reader.read(buff)) != -1) { System.out.println(new String(buff, 0, length)); } httpclient.getConnectionManager().shutdown(); } }
服务端接收方式：
