Unity3D 将 json 发布到 ASP.NET MVC 4 Web Api [英] Unity3D post a json to ASP.NET MVC 4 Web Api

问题描述

我如何向 ASP.NET MVC 4 Web Api 控制器发布带有 json 值的帖子?我尝试了几种方法，但我无法使其正常工作.

How I do a post with json value to a ASP.NET MVC 4 Web Api Controller? I tried it several ways, but I can't make it works.

首先，我简化的控制器操作:

First, my simplified Controller action:

[HttpPost]
public Interaction Post(Interaction filter)
{
     return filter;
}

以及我使用 Unity3D WWW 的 post 方法:

And my post method with Unity3D WWW:

public string GetJson(string url, WWWForm form)
{
    var www = new WWW(url, form);

    while (!www.isDone) { };

    return www.text;
}

我的 WWWForm 在哪里:

Where my WWWForm is:

var form = new WWWForm();
form.AddField("filter", interaction);

我尝试指定标题，例如:

I tried specify the header, like:

public string GetJson(string url, byte[] data)
{
    var header = new Hashtable();
    header.Add("Content-Type", "text/json");

    var www = new WWW(url, data, header);

    while (!www.isDone) { };

    return www.text;
}

我真的尝试了十多种不同的方法来解决这个问题，但我总是得到相同的结果:

I really tried to solve this by more than ten different ways and I always get the same result:

Debug.Log(input); // {"Id":15,"Name":"Teste","Description":"Teste","Value":0.0,"Time":10.0}
Debug.Log(output); // {"Id":0,"Name":null,"Description":null,"Value":0.0,"Time":0.0}

任何方向都会有所帮助.谢谢！

Any direction will be helpful. Thanks!

推荐答案

不要使用 WWWForm 发布 JSON.使用这样的东西.

Do not use WWWForm to post JSON. Use something like this.

string input = "You JSON goes here";

Hashtable headers = new Hashtable();
headers.Add("Content-Type", "application/json");

byte[] body = Encoding.UTF8.GetBytes(input);

WWW www = new WWW("http://yourserver/path", body, headers);

yield www;

if(www.error) {
         Debug.Log(www.error);
}
else {
        Debug.Log(www.text);
}

假设输入中的JSON字符串是这样的，

Assuming JSON string in input is like this,

{"Id":15,"Name":"Teste","Description":"Teste","Value":0.0,"Time":10.0}

你需要这样的课程

public class Interaction
{
   public int Id { get; set; }
   public string Name { get; set; }
   public string Description { get; set; }
   public string Teste { get; set; }
   // other properties
}

为了让这样的动作方法起作用

for the action method like this to work

public Interaction Post(Interaction filter)
