统一应用程序没有响应，并在调用WebAPI时获得“请求超时”

Question

我有一个对DLL中的Like()方法的Unity调用，该方法连接到一个WebAPI来完成这项工作。但是，当我调试应用程序和运行到

string liked = SocialConnector.LikePost(token, postID);

它被卡在那里，统一变得没有响应，在正常工作之后，调试显示请求超时。

下面是我在DLL中的详细代码

public static String LikePost(String token, String postID)
    {
        HttpCommon common = new HttpCommon();
        string url = Constant.ApiURL + Constant.API_LINK_POST_LIKE_UNLIKE + "?postID=" + postID;
        String result = common.HttpPost<String>(url, token);
        return result;
    }

HTTPCommon中的代码

public T HttpPost<T>(String url, String token)
    {
        var request = (HttpWebRequest)WebRequest.Create(url);

        //var data = Encoding.ASCII.GetBytes(postData);
        request.Method = "POST";
        request.ContentType = "application/x-www-form-urlencoded";
        //request.ContentLength = data.Length;
        request.Headers["Authorization"] = "Bearer " + token;
        var stream = request.GetRequestStream();
        var response = (HttpWebResponse)request.GetResponse();
        var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
        try
        {                
            var responseData = JsonConvert.DeserializeObject<T>(responseString);
            return responseData;
        }
        catch (Exception e)
        {
            throw new Exception(responseString);
        }
    }

更新：问题解决了。WebAPI返回类型的bool，但我的DLL强制返回字符串。
