Question

我正在构建一个unity3d-webgl应用程序，该应用程序使用assetbundle加载3d模型。到目前为止，我无法加载任何资产捆绑包，在浏览器的控制台窗口中看到的全部是“无法打开存档文件：http://192.168.1.106/webgl/StreamingAssets/Wheels/tis”

我正在使用Unity 2018.3，并且有一台单独的Linux服务器运行Ubuntu（因此没有localhost），我还测试了firefox，chrome和edge的构建，但在所有浏览器中都遇到相同的错误。我什至已经做了一个开发人员构建，它只给了我同样的错误信息，而没有任何其他解释。

        foreach (Manufacturer man in m_resources.manufacturers.manufacturers)
        {

                foreach (Wheel w in man.wheels)
                {

                        // remove old wheel from scene
                        if (m_wheelHolder.transform.childCount > 0)
                            foreach (Transform t in m_wheelHolder.transform)
                                GameObject.Destroy(t.gameObject);

                        // place wheel in scene
                        GameObject instance = Instantiate((GameObject)assetLoadRequest.asset);
                        instance.name = instance.name.Replace("(Clone)", string.Empty);

                        instance.transform.parent = m_wheelHolder.transform;
                        instance.transform.localPosition = new Vector3(0, 0, 0);

                        m_wheelPrep.Setup();
                    }
                }

                // all assets loaded...
                m_LoadCompleteEvent.Invoke();
            }
        }
    }

我遵循了针对webgl与Windows独立构建资产的统一指南。当我为Windows独立构建项目并使用独立资产捆绑包时，一切正常。我只在webgl中遇到问题。

注意：我起初虽然该文件需要文件扩展名，所以这就是为什么有一个名为m_extension的变量的原因。即使有代码，添加扩展也无济于事，在Unity编辑器中变量为空。
