       var postData = {
            tid: tid,
            code: courierId,
            outSid: outsid
        };
        $.ajax({  
            type : "POST",  
            url : "../courier/send", 
            data: postData,
            success : function(data) {
                ..........
            }  
        }); 

    @RequestMapping("/send")
    @ResponseBody
    public CommonResult send(String tid, String code, String outSid){
          ..............
    }    

        var data = ‘{"buyerNick":"‘+buyerNick+‘"}‘;
        $.ajax({  
            type : "POST",  
            url : "../print/getbuyertrade", 
            dataType: ‘json‘,
            contentType: "application/json;charset=UTF-8",

            success : function(data) {
　　　　　　　　   ..........
            }
        });

        @RequestMapping("/getbuyertrade")
