bottle纹理加载不出来，代码如下

loadTexture () {
    const loader = new THREE.TextureLoader()
    const specularTexture = loader.load('/game/res/images/head.png')
    const middleTexture = loader.load('/game/res/images/middle.png')
    const bottomTexture = loader.load('/game/res/images/bottom.png')
    const specularMaterial = new THREE.MeshBasicMaterial({
      map: specularTexture
    })
    const middleMaterial = new THREE.MeshBasicMaterial({
      map: middleTexture
    })
    const bottomMaterial = new THREE.MeshBasicMaterial({
      map: bottomTexture
    })

    return {
      specularMaterial,
      middleMaterial,
      bottomMaterial
    }
  }

const {
      specularMaterial,
      middleMaterial,
      bottomMaterial
    } = this.loadTexture()

    const top = new THREE.Mesh(
      new THREE.SphereGeometry(headRadius / 1.4, 20, 20),
      bottomMaterial
    )
    const head = new THREE.Mesh(
      new THREE.OctahedronGeometry(headRadius),
      specularMaterial
    )

 const specularTexture = loader.load('/game/res/images/head.png', function(texture) {
      console.log(texture.image.currentSrc) // 拿到 http://127.0.0.1:58577/game/res/images/head.png，这个地址在浏览器中都无法访问，
    })

请问各位大佬，这是哪里出问题了？
