Question

我使用以下命令从库中创建了带有示例代码的文件“ convert.js” 运行（“模型n”，“路径/到/输出/文件夹”）；在gltf中获取模型。在控制台中运行“ node convert.js”时，出现错误。

我的步骤：1.创建项目2.npm安装forge-convert-utils 3.npm安装dotenv。 4.npm install forge-server-utils 5.创建文件convert.js，文件夹“文件夹”和配置文件.env 6。节点convert.js

convert.js

const { ModelDerivativeClient, ManifestHelper } = require('forge-server-utils');
const { SvfReader, GltfWriter } = require('forge-convert-utils');
require('dotenv/config');
const { FORGE_CLIENT_ID, FORGE_CLIENT_SECRET } = process.env;

async function run (urn, outputDir) {
    const auth = { client_id: FORGE_CLIENT_ID, client_secret: FORGE_CLIENT_SECRET };
    try{
        const modelDerivativeClient = new ModelDerivativeClient(auth);
        // crashed
        const helper = new ManifestHelper(await modelDerivativeClient.getManifest(urn));
        const derivatives = helper.search({ type: 'resource', role: 'graphics' });
        const writer = new GltfWriter(outputDir);
        for (const derivative of derivatives.filter(d => d.mime === 'application/autodesk-svf')) {
            const reader = await SvfReader.FromDerivativeService(urn, derivative.guid, auth);
            const svf = await reader.read();
            writer.write(svf);
        }
        writer.close();
    }
    catch (e) {
        console.log(e);
    }
}

（节点：12108）UnhandledPromiseRejectionWarning：未处理的承诺拒绝。该错误是由于抛出没有catch块的异步函数而引起的，或者是由于拒绝了不是与.catch（）并存。（拒绝ID：2）

Answer 1

堆栈跟踪说明的不多，只是Forge中缺少某些内容。尝试将run函数的内部包装在try-catch块中，以获取更多有关抛出异常的信息。

请注意，forge-convert-utils库假定已使用模型导数服务（使用POST job）翻译了URN。

无法使用forge-convert-utils转换gltf
