### **一个demo了解一下** ###

我做的是一个app,后台使用java做的,app通过ajax来请求后台，但是我不知道后台有没有请求成功！

因此需要一个测试接口的东西测试我做的接口有没有问题

我的app里面的ajax是这样写的

api.ajax({
          url: 'http://192.168.0.107:8080/jiekou/RegeditServlet',
          method: 'get',
          dataType:'JSON',
          returnAll:true,
          timeout:30,
          data: {
              values: {
                  name: user,
                  pass: ps
              }
          }
      },function(ret, err){
          if (ret) {
              api.alert( JSON.stringify( ret ) );
          } else {
              api.alert(JSON.stringify( err ) );
          }
      });

请求方式是get post什么的，根据自己的需求选

url就是自己请求后台的路径

key是属性名 value是属性值都和后台要接收都属性名一致

附上我的java后台接收的servlet的代码，方便理解postman的流程

package cn.com.servlet;
    import java.io.IOException;
    import java.util.ArrayList;
    import javax.servlet.ServletException;
    import javax.servlet.http.HttpServlet;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import cn.com.bean.User;
    import net.sf.json.JSONArray;
    public class RegeditServlet extends HttpServlet {
    	private static final long serialVersionUID = 1L;
    	public void doGet(HttpServletRequest request, HttpServletResponse response)
    			throws ServletException, IOException {
    		//ServletContext ser = getServletContext();
    		//ApplicationContext ioc = (ApplicationContext) ser.getAttribute("app");
    		doPost(request, response);
    		//Regedit re=ioc.getBean(Regedit.class);
    		//re.login();
    	}
    	public void doPost(HttpServletRequest request, HttpServletResponse response)
    			throws ServletException, IOException {
    		request.setCharacterEncoding("utf-8");
    		String user=request.getParameter("name");
    		String pass=request.getParameter("pass");
    		System.out.println("用户名："+user);
    		System.out.println("密码："+pass);
    		  //将List转化为JSON
    		System.out.println("----------");
    		String ty="java与apicloud的前后台交互！！";		
    		ArrayList<String> list=new ArrayList<String>();
    		list.add(ty);
            JSONArray json=JSONArray.fromObject(list);
            //设置编码
            response.setCharacterEncoding("utf-8");
            //写入到前台
            response.getWriter().write(json.toString());
    
    	}
    
    }

如下图

然后点击send，就会返回java后台给前台页面传递的数据

--------------------

有返回值，说明java这个接口没有问题
