Question

我正在尝试使用three.js加载位于本地文件夹中的.gltf文件，但是在控制台上指控此错误：“不允许加载本地资源”。

已经尝试使用http服务器运行；试图创建一个dist并从那里运行http-server；试图给予浏览器许可（使用谷歌浏览器，使用--allow-file-access-from-files选项）；我还已经在在线渲染器中渲染了.gltf文件，只是为了确保3D模型没有问题并且一切正常。

typesccript类：


export class AppComponent {
  title = 'three-app';
  @ViewChild('rendererContainer') rendererContainer: ElementRef;

  renderer = new THREE.WebGLRenderer();
  scene = null;
  camera = null;
  mesh = null;

  constructor() {
    this.scene = new THREE.Scene();

    this.camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 1, 10000);
    this.camera.position.z = 1000;
    var loader = new GLTFLoader();

  loader.load( 'C:\\Users\\x\\Desktop\\3dmodels\\box.gltf', function ( gltf ) {

    this.scene.add( gltf.scene );

  }, undefined, function ( error ) {

    console.error( error );

  } );
  } 
}

html：

<div #rendererContainer></div>

有人知道会发生什么吗？

Answer 1

您可能想尝试使用文件URL。 “ C：\ Users \ x \ Desktop \ 3dmodels \ box.gltf”不是URL，但“ file：// C：\ Users \ x \ Desktop \ 3dmodels \ box.gltf”是URL。

请注意，我没有Windows环境可以尝试此操作，因此我不确定YMMV格式是否正确。

Answer 2

我使用“ Chrome的Web服务器”扩展名解决了。我创建了一个本地服务器，将3D文件丢到那里，然后通过传递本地服务器URL设法加载它。该扩展名具有“设置CORS标头”选项，该选项允许其他来源的XMLHttpRequests。
