jQuery post array - ASP.Net MVC 4
提问by Silent
I have spent 8 hours or so today trying to figure this out. I have viewed lots of solutions but cannot get the same results. I have a hunch it has everything to do with being relatively new to ASP.Net.
我今天花了 8 个小时左右的时间试图解决这个问题。我查看了很多解决方案，但无法获得相同的结果。我有一种预感，这与 ASP.Net 相对较新有关。
Here is the latest question I tried mimicking with no luck. https://stackoverflow.com/questions/10007722/post-array-as-json-to-mvc-controller#=

How to post an array of complex objects with JSON, jQuery to ASP.NET MVC Controller?
如何使用 JSON、jQuery 将一组复杂对象发布到 ASP.NET MVC 控制器？
Basic Rundown of Problem: I have an array of json objects I would like to pass to my controller. When I pass the data it shows lets say for example 3 items, but their values are not passed or it just shows nothing was passed. Firebug shows it passed it so I assume that something is not setup right and its not allowing it to set that variable up correctly on the C# side.
问题的基本概要：我有一组 json 对象，我想传递给我的控制器。当我传递它显示的数据时，可以说例如 3 个项目，但它们的值没有传递，或者它只是显示没有传递任何内容。Firebug 显示它通过了它，所以我假设某些东西没有正确设置并且它不允许它在 C# 端正确设置该变量。
I have tried a few things and ill list them below: Setup 1: I tried mocking what I seen at the second link:
我已经尝试了一些事情，并在下面列出了它们： 设置 1：我尝试嘲笑我在第二个链接中看到的内容：
$.ajax({
type: 'Post',
cache: false,
url: '/Workflow/Home/UpdateStepPositions',
data: { 'steps': ['1','2','3'] },
async: false,
success: function (data) {
console.debug(data);
},
error: function (data) {
console.debug(data);
}
});
Controller
[HttpPost]
public ActionResult UpdateStepPositions(string[] steps){
var bresults = new {
Success = false,
Message = "Unable to update step positions."
};
return Json(bresults);
}
I couldn't even get that simple setup working.. It gets to the function and shows there was nothing passed....
我什至无法让那个简单的设置工作..它进入函数并显示没有任何通过......
Setup 2:
设置 2：
list = new Array();
list.push({ "step": 1, "position": 1 });
list.push({ "step": 2, "position": 2 });
list.push({ "step": 3, "position": 3 });
$.ajax({
type: 'Post',
cache: false,
url: '/Workflow/Home/UpdateStepPositions',
data: JSON.stringify({ 'steps': list }),
async: false,
success: function (data) {
console.debug(data);
},
error: function (data) {
console.debug(data);
}
});
Controller
[HttpPost]
public ActionResult UpdateStepPositions(List<UpdatedSteps> steps){
var bresults = new {
Success = false,
Message = "Unable to update step positions."
};
return Json(bresults);
}
Class
public class UpdatedSteps {
public string Step { get; set; }
public string Position { get; set; }
}
Can anyone shine some light on what I'm missing or point me in the right direction? Hopefully its something simple and just a newbie mistake!
任何人都可以照亮我所缺少的东西或指出我正确的方向吗？希望它的东西很简单，只是一个新手错误！

MVC detects what type of data it receive by contentType. Here is working example:
MVC 通过 contentType 检测它接收的数据类型。这是工作示例：
$(function () {
$.ajax({
type: 'Post',
dataType: 'json',
url: '/Workflow/Home/UpdateStepPositions',
data: JSON.stringify({ steps: ['1', '2', '3'] }),
contentType: 'application/json; charset=utf-8',
async: false,
success: function (data) {
console.debug(data);
},
error: function (data) {
console.debug(data);
}
});
});
Now everything ok with request:
现在一切正常，请求：
Content-Type: application/json; charset=utf-8
X-Requested-With: XMLHttpRequest
and response:
和回应：
Content-Type: application/json; charset=utf-8
