我正在尝试调用我的自定义 api，它使用回形针上传文件，它在本地使用https://github.com/jwagener/httmultiparty可以正常工作，但是当我尝试调用 api 并为 heroku 部署的应用程序上传文件时，出现以下错误发生。

我在 ruby​​ 控制台上运行它来测试文件上传 api。

HttpClient.post('/storage.xml',:basic_auth=>   {:username=>'badde88248834bec759d94563f102d52e19702fa',:password=>'b890b48e2769192372bf531fc46827cd86bea23f'} ,:query => {:auth_token=> '1045aa26cda23f5f3aec737a45e7ba0017c1a7cf',:user_file => File.new( '/home/umair/Login.png')})

three.js：将坐标从相机空间转换到场景空间

我试图相对于相机放置一个立方体，而不是相对于场景。问题是，要将它放置在场景中（我必须让它显示），我必须知道对应于立方体相机空间坐标的场景坐标。我在 THREE.Camera 中找到了这个函数“projectionMatrixInverse”。它有一个很好的函数，叫做“multiplyVector3”，我希望它能让我将向量 (1,1,1) 转换回场景空间，如下所示：

var camera, myvec, multvec; // (and others)
camera = new THREE.OrthographicCamera( window.innerWidth / - 2, window.innerWidth / 2, window.innerHeight / 2, window.innerHeight / - 2, - 2000, 1000 );
camera.position.x = 200;
camera.position.y = 100;
camera.position.z = 200;

myvec = new THREE.Vector3(1,1,1);
console.log("myvec: ", myvec);
multvec = camera.projectionMatrixInverse.multiplyVector3(THREE.Vector3(1,1,1));
console.log("multvec: ", multvec);

问题是，在控制台上我得到：

myvec: Object { x=1, y=1, z=1}
TypeError: v is undefined
var vx = v.x, vy = v.y, vz = v.z;

multiplyVector3 根本不接受 my myvec，或者说它是未定义的，即使控制台说它是一个对象。我不明白。

我遇到了同样的问题，找不到解决方案。现在我正在这样做，它只需要multipart-post宝石。

class Client
  require 'net/http/post/multipart'

  def self.perform inputurl, file
    url = URI.parse(inputurl)
    File.open(file) do |transfile|
      Net::HTTP.start(url.host, url.port) do |http|
        req = Net::HTTP::Post::Multipart.new(
          url.path,
          file1: UploadIO.new(transfile, "multipart/formdata", File.basename(file)),
        )
        response = http.request(req)
      end
    end
  end
end
