未经授权通过forge API下载SVF衍生品

autodesk-model-derivative autodesk-forge node.js

user8246956 · 技术社区 · 9 年前

extract.autodesk.io 模块( SVF model derivative downloaded as an (almost) empty ZIP file (Autodesk Forge) 模块,在两条腿的上下文中。

以下是我试图实现的一个简单示例:

var ForgeSDK = require("forge-apis");

/* The next four lines are filled with my credentials and URN values 
 * (this shouldn't be the problem, since getting the manifest for the URN
 * is performed successfully) */
var client_id = "...";
var client_secret = "...";
var urn = "...";
var derivative_urn = "...";

var derivatives = new ForgeSDK.DerivativesApi();
var autoRefresh = true;
var oAuth2TwoLegged = new ForgeSDK.AuthClientTwoLegged(client_id, 
    client_secret, [
        "data:read", "data:write", "bucket:read", "bucket:write"
    ], autoRefresh);

oAuth2TwoLegged.authenticate().then(function(credentials) {
    derivatives.getDerivativeManifest(urn, derivative_urn, {}, credentials, oAuth2TwoLegged).then(function(content) {
        console.log(content);
    }).catch(function(err) {
        if (err) {
            console.log(err);
        }
    })
});

我得到以下错误:{statusCode:401,statusMessage:'未授权'}。这是一个范围问题吗?

提前多谢!

extract.autodesk.io 提供了一个很好的方法,但我觉得使用对象在另一个上下文中转置并不那么简单。这个模块应该无缝地完成这项工作(或者我遗漏了什么)。

:根据Augusto的建议,我使用了最基本的命令(即cUrl)从IFC文件下载信息。下面的前两个命令成功运行(加载清单和PNG屏幕截图文件)。SVF的下载似乎也很好,除了ZIP文件只包含两个JSON文件(manifest.JSON和metadata.JSON),以及三个空目录(geometry、material、scene)。

代码如下:

# Get manifest for the IFC file
curl -X "GET" -H "Authorization: Bearer $TOKEN" -v "https://developer.api.autodesk.com/modelderivative/v2/designdata/$URN_IFC/manifest" > manifest.json

# Get a PNG related to the IFC file
curl -X "GET" -H "Authorization: Bearer $TOKEN" -v "https://developer.api.autodesk.com/modelderivative/v2/designdata/$URN_IFC/manifest/$URN_PNG" > image.png

# Get the SVF converted from the IFC file
curl -X "GET" -H "Authorization: Bearer $TOKEN" -v "https://developer.api.autodesk.com/modelderivative/v2/designdata/$URN_IFC/manifest/$URN_SVF" > output.zip

知道吗?

正在查看 the implementation npm forge-apis@0.4.1 ,签名为:

this.getDerivativeManifest = function(urn, derivativeUrn, opts, oauth2client, credentials)

但你的代码似乎在使用 oauth2client credentials 以相反的顺序。在这一改变之后,它在这里工作得很好。

var derivatives = new ForgeSDK.DerivativesApi();
var autoRefresh = true;
var oAuth2TwoLegged = new ForgeSDK.AuthClientTwoLegged(client_id, 
    client_secret, [
        "viewables:read"
    ], autoRefresh);

oAuth2TwoLegged.authenticate().then(function(credentials) {
    derivatives.getDerivativeManifest(urn, derivative_urn, {}, oAuth2TwoLegged, credentials).then(function(content) {
        console.log(content);
    }).catch(function(err) {
        if (err) {
            console.log(err);
        }
    })
});

建议仅使用 viewables:read 范围,因为您不需要所有这些额外的权限(至少对于此代码)。

bubble.js 功能来自 extract.autodesk.io

谢谢@Augusto的帮助。仍然很想知道为什么“基本”旋度方法没有按预期工作。。。
