这是我所有的代码。我正在使用 Apache2.2 服务器，我使用 python 将我的模型从 FBX 转换为 Json。这是我收到的错误消息：

THREE.WebGLRenderer 57 three.js:18058
Uncaught SyntaxError: Unexpected token , three.js:9764
xhr.onreadystatechange three.js:9764

     xhr.onreadystatechange = function () {
        
                if ( xhr.readyState === xhr.DONE ) {
        
                    if ( xhr.status === 200 || xhr.status === 0 ) {
        
                        if ( xhr.responseText ) {
        
                            var json = JSON.parse( xhr.responseText );//*Uncaught SyntaxError: Unexpected token*
                            var result = context.parse( json, texturePath );
                            callback( result.geometry, result.materials );

有什么建议可能是错的？？？我尝试了许多不同的解决方案，但似乎没有任何效果，我感到非常迷茫。

谢谢！！！

编辑：这是 python FBX 到 JSON 转换器给我的示例：

    "metadata": {
        "formatVersion" : 3.2,
        "type"      : "scene",
        "generatedBy"   : "convert-to-threejs.py",
        "objects"       : 1,

        "materials"     : 1,
        "textures"      : 1
    },


    "urlBaseType": "relativeToScene",

    "objects" :
    {
        "Tire_Front" : {

            "visible"  : true
        }
    },

    "geometries" :

我在您的 .json 文件中发现了一些“Uncaught SyntaxError：Unexpected token”的来源。请注意语法，包括括号“{”或“[”。

{
    "metadata": {
        "formatVersion" : 3.2,
        "type"      : "scene",
        "generatedBy"   : "convert-to-threejs.py",
        "objects"       : 1,
        "geometries"    : 1,
        "materials"     : 1,
        "textures"      : 1
    },


    "urlBaseType": "relativeToScene",

    "objects" :
    {
        "Tire_Front" : {
            "geometry" : "Geometry_40_Tire_Front",
            "material" : "Material #3319",
            "position" : [ 0, -423.113, 451.225 ],
            "rotation" : [ -1.5708, 0.000987928, 6.04932e-20 ],
            "scale"    : [ 1, 1, 1 ],
            "visible"  : true
        }
    },

    "geometries" :
    {
        "Geometry_40_Tire_Front" : {
            "type"  : "embedded",
            "id" : "Embed_40_Tire_Front"
        }
    }

}

使用“OBJLoader”而不是“JSONLoader”来加载对象也有帮助。
