X5 中当设置动作的参数是Object时需要设置contentType: "application/json"

最近遇到的一个问题X5 Action能接收Object 的参数

 

var params = new justep.Request.ActionParam();

 

//对象参数，ObjectParam对应的class必须有包名

var objectSerialize = {name: "霍金", sex: "男", age: 70}; 

//var objectSerialize = "<DemoObject name='霍金' sex='男' age='70'></DemoObject>"; 

 

var objectParam = new justep.Request.ObjectParam(objectSerialize, "demo.DemoObject");

params.setObject("param_object", objectParam);

 

justep.Request.sendBizRequest2({

       contentType: "application/json",//这个代码不能忘记

action: "demoObjectTest",

parameters: params,

callback: function(result) {

if (result.state) {

alert("调用成功！");

} else {

throw new Error("调用失败！|" + result.response.message);

}

}

});

 

否则报错：

错误原因是：

  contentType: "application/json" 这个contentType 指string 发送请求的格式 ，如果不指定默认是如下格式

'application/x-www-form- urlencoded' （其他解释见http://www.cnblogs.com/mumue/archive/2012/05/24/2515984.html）
