使用jQuery向asp.net Mvc传递复杂json数据-ModelBinder篇

调用jQuery的ajax方法时,jQuery会根据post或者get协议对参数data进行序列化;
如果提交的数据使用复杂的json数据,例如:
{userId:32323,userName:{firstName:”李”,lastName:”李大嘴”}}
那么服务器是无法正常接收到完整的参数,因为jQuery对data的序列化,是使用了键值对拼装的方式;
参数拼装成 userId=32323&userName=object ; userName所指向的对象被序列化成字符串”object”

如何才能把一个复杂的object对象提交到后台的action参数中呢?
首先,解决jQuery对于参数序列化的问题:

/*对象序列化为字符串*/
String.toSerialize = function(obj) {
var ransferCharForJavascript = function(s) {
var newStr = s.replace(
/[x26x27x3Cx3Ex0Dx0Ax22x2Cx5Cx00]/g,
function(c) {
ascii = c.charCodeAt(0)
return ‘u00’ + (ascii < 16 ? ‘0’ + ascii.toString(16) : ascii.toString(16))
}
);
return newStr;
}
if (obj == null) {
return null
}
else if (obj.constructor == Array) {
var builder = [];
builder.push(“[“);
for (var index in obj) {
if (typeof obj[index] == “function”) continue;
if (index > 0) builder.push(“,”);
builder.push(String.toSerialize(obj[index]));
}
builder.push(“]”);
return builder.join(“”);
}
else if (obj.constructor == Object) {
var builder = [];
builder.push(“{“);
var index = 0;
for (var key in obj) {
if (typeof obj[key] == “function”) continue;
if (index > 0) builder.push(“,”);
builder.push(String.format(“”{0}”:{1}”, key, String.toSerialize(obj[key])));
index++;
}
builder.push(“}”);
return builder.join(“”);
}
else if (obj.constructor == Boolean) {
return obj.toString();
}
else if (obj.constructor == Number) {
return obj.toString();
}
else if (obj.constructor == String) {
return String.format(‘”{0}”‘, ransferCharForJavascript(obj));
}
else if (obj.constructor == Date) {
return String.format(‘{“__DataType”:”Date”,”__thisue”:{0}}’, obj.getTime() – (new Date(1970, 0, 1, 0, 0, 0)).getTime());
}
else if (this.toString != undefined) {
return String.toSerialize(obj);
}
}

jQuery异步请求:

$(function() {
/*按钮点击事件*/
$(“#btn_post_test”).click(function() {
var data = [
{ UserId: “11”, UserName: { FirstName: “323”, LastName: “2323” }, Keys: [“xiaoming”, “xiaohong”] },
{ UserId: “22”, UserName: { FirstName: “323”, LastName: “2323” }, Keys: [“xiaoming”, “xiaohong”] },
{ UserId: “33”, UserName: { FirstName: “323”, LastName: “2323” }, Keys: [“xiaoming”, “xiaohong”] }
