下面用Jmeter发送一个post请求,
  对应的js代码如下:

 

$("#register_a").click(function() {
var name = $("#uname").val();
var pwd = $("#pwd").val();
var email = $("#email").val();
var user = {
"name" : name,
"password" : pwd,
"email" : email
};
$.ajax({
beforeSend: function(xhrObj){
xhrObj.setRequestHeader("Content-Type","application/json");
xhrObj.setRequestHeader("Accept","application/json");
},
type : "POST",
url : "./register",
contentType : "application/json;charset=utf-8",
data : JSON.stringify(user),
success : function(data) {
return;
//  window.location.href = "./u_" + data.id + "/";
},
dataType : "json"
});
});

  jmeter配置如下:
