HttpClient4入门应用之二----Post方法访问Action带传参

Struts2的Action配置代码

<package name="Ajax" extends="json-default" namespace="/Ajax">
    <action name="serivceJ" class="com.wanghe.test.TestAction" method="serivceJ" >
   		<result  type="json"></result>
	</action>
</package>

Action代码

public void serivceJ() {
        try {
    HttpServletResponse response = ServletActionContext.getResponse(); 
HttpServletRequest request = ServletActionContext.getRequest();
 System.out.println("request...serivceJ");
	    response.setCharacterEncoding("UTF-8");
	        String type = request.getParameter("type");
	        String c = "none";
	        if(type.equalsIgnoreCase("girl")){
	        	c = "女孩你好！";
	        }else if(type.equalsIgnoreCase("boy")){
	        	c = "男孩你好！";
	        }
			response.getWriter().write(c);
		} catch (IOException e) {
			e.printStackTrace();
		}
	}

HttpClient测试代码

//创建默认的httpClient实例.
HttpClient httpclient = new DefaultHttpClient();
//创建httppost
HttpPost httppost = new HttpPost("http://localhost:8080/myDemo/Ajax/serivceJ.action");
//创建参数队列
List<NameValuePair> formparams = new ArrayList<NameValuePair>();
formparams.add(new BasicNameValuePair("type", "girl"));
UrlEncodedFormEntity uefEntity;
try {
	uefEntity = new UrlEncodedFormEntity(formparams, "UTF-8");
	httppost.setEntity(uefEntity);
	System.out.println("executing request " + httppost.getURI());
	HttpResponse response;
	response = httpclient.execute(httppost);
	HttpEntity entity = response.getEntity();
	if (entity != null) {		System.out.println("--------------------------------------");
	System.out.println("Response content: " + EntityUtils.toString(entity,"UTF-8"));
System.out.println("--------------------------------------");
			}
		} catch (ClientProtocolException e) {
			e.printStackTrace();
		}catch(UnsupportedEncodingException e1) {
			e1.printStackTrace();
		}catch (IOException e) {
			e.printStackTrace();
		}finally{
             //关闭连接,释放资源
			httpclient.getConnectionManager().shutdown();
		}

输出：

executing request http://localhost:8080/myDemo/Ajax/serivceJ.action
--------------------------------------
Response content: 女孩你好！
--------------------------------------
