ruby-on-rails - Ruby on Rails Controller 重定向不会在 WEBGL 运行时发生

标签 ruby-on-rails unity3d iframe unity-webgl

我有一个 WEBGL 播放器作为“demo_path”嵌入到 rails 静态页面中，如下所示:

<% provide(:title, 'Sign up') %>
<h1>Sign up</h1>

<div class="row">
<div class="col-md-6 col-md-offset-3">
<%= form_for(@user, url: signup_path) do |f| %>
  <%= render 'shared/error_messages' %>

  <%= link_to "mindpass", demo_path, class: "btn btn-lg btn-primary" 
%>

  <%= f.submit "Create my account", class: "btn btn-primary" %>
<% end %>
</div>
</div>

当用户单击按钮时，它会加载 webgl 模板:
<!DOCTYPE html>
<html lang="en-us">
  <head>
    <meta charset="utf-8">
    <meta http-equiv="Content-Type" content="text/html; charset=utf- 
8">
<title>Unity WebGL Player | MindPass_DEMO</title>
<script src="Build/UnityLoader.js"></script>
<script>
  var gameInstance = UnityLoader.instantiate("gameContainer", 
"/assets/Build/MindPass_WEBGL_RY2.json");
</script>
</head>
<body>
<div id="gameContainer" style="width: 90%; height: 90%; position: 
absolute; margin: auto;"></div>
  </body>
</html>

这将成功加载并实际启动用户 Controller 以保存新用户并启动“redirect_to @users”，如下面的 users_controller 代码所示:
def create
    puts "create runs"
    #puts params.inspect
    @user = User.new(user_params)
    if @user.save

      puts "user save runs"
      log_in @user
      puts "second welcome to your vault(users_cont)"
      flash[:success] = "Welcome to your vault!"
      redirect_to @user
    else
      puts "render new runs"
      render 'new'
    end
  end

问题是重定向实际上并没有发生。这是尝试的日志，包括重定向:

当我使用下面的普通表单输入执行此操作时，会发生相同的重定向日志，并且它实际上转到用户页面。:
  <%= f.label :email %>
  <%= f.email_field :email, class: 'form-control' %>

  <%= f.label :password %>
  <%= f.password_field :password, class: 'form-control' %>

似乎 WEBGL 正在锁定这件事并拒绝页面实际重定向，即使它应该发生。我错过了什么？

更新 12-6-18:

我注意到当 WEBGL 启动重定向(不成功)时，我在日志中得到了这个:Processing by UsersController#show as/。如果我从一个普通的 html 表单(成功)重定向，我会在日志中得到这个:Processing by UsersController#show as HTML。这是日志中的唯一区别。

我已经测试了以下内容:
  • 使用多个浏览器进行测试以查看它是否特定于某些浏览器
  • 通过将重定向 URL 更改为 https://www.google.co.uk/ 进行测试查看重定向是否成功
  • 添加了一个条件以确保在继续执行脚本之前完成重定向
  • 尝试通过 LocalHost 对 Heroku 进行测试(仍然没有继续)
    可悲的是，这些测试都没有产生任何有说服力的结果。

    • 来自游戏实例的适用 UnityWebRequest C# 代码:
    phase4 = true;
        Invoke ("QuitGame", 10f);
  }
      }

    private  IEnumerator  Connection ( string  name )
    {
    WWWForm  form  =  new WWWForm ();
    form . AddField ( "EMAIL" ,  _email );
    form . AddField ( "PASSWORD" ,  passwordUnityEncrypted );
    form . AddField ( "HOST_URL" ,  absoluteURL );
    form . AddField ( "SIGNUP_PATH" ,  _url_signup_route );
    form . AddField ( "LOGIN_PATH" ,  _url_login_route );

    if (absoluteURL == _url_signup){
    UnityWebRequest  request  =  UnityWebRequest . Post ( 
    _url_signup_route ,  form );
    yield  return  request . Send ();
    } else{
    UnityWebRequest  request  =  UnityWebRequest . Post ( 
    _url_login_route ,  form );
    yield  return  request . Send ();
    }

    最佳答案

    我在这里做了一些假设，但我假设 gameInstance 背后的 javascript正在提交发布请求，如果是这种情况，那么我会检查它是否正确处理了重定向。

    更新

    您将需要手动处理重定向(如果我正确理解 Unity 文档)。

    您可以使用 UnityWebRequest.GetResponseHeader 从位置 header 中获取重定向 URL。

    获得位置 URL 后，您应该可以使用 Application.OpenURL如果您使用网络播放器，这将更新浏览器位置。

    private  IEnumerator  Connection ( string  name ) {
  WWWForm  form  =  new WWWForm ();
  form . AddField ( "EMAIL" ,  _email );
  form . AddField ( "PASSWORD" ,  passwordUnityEncrypted );
  form . AddField ( "HOST_URL" ,  absoluteURL );
  form . AddField ( "SIGNUP_PATH" ,  _url_signup_route );
  form . AddField ( "LOGIN_PATH" ,  _url_login_route );

  string post_url = "";
  if (absoluteURL == _url_signup) {
    post_url = _url_signup_route;
  } else { 
    post_url = _url_login_route;
  }

  UnityWebRequest request = UnityWebRequest.Post(post_url, form);
  yield  return  request.Send();

  string location = request.GetResponseHeader('location');
  Application.OpenURL(location);
}

    我的 C# 生锈/不存在，所以那里可能有错误，但这应该给你一个方向。
