HttpClient

看了几天的HttpClient，写了一点代码，留到以后用。

使用的是common-httpclient.jar

  1 public void SendHttpRequest(){
  2         PostMethod method=null;
  3         String url="http://localhost:8080/com.isoftstone.iics.bizsupport.epps/epolicy/create";
  4         String xmlString="";
  5         method=new PostMethod(url);
  6         client.getParams().setContentCharset("utf-8");
  7         try
  8         {
  9             client.getHttpConnectionManager().getParams().setConnectionTimeout(6000);
 10             RequestEntity entity=new StringRequestEntity(xmlString,"text/xml","utf-8");
 11             method.setRequestEntity(entity);
 12             client.executeMethod(method);
 13             String response=method.getResponseBodyAsString();
 14             System.out.println(response+"------");
 15             method.releaseConnection();
 16         } catch (Exception e)
 17         {
 18             // TODO Auto-generated catch block
 19             e.printStackTrace();
 20         }
 21 //        RequestEntity entity = new StringRequestEntity(xmlString, "text/xml", encoding);

HttpClient就先看到这把！
