Autodesk伪造文件转换为svf不工作

Question

我目前正在按照“自动桌面锻造”上的“准备查看者教程”的文件进行操作。这是链接：https://forge.autodesk.com/en/docs/model-derivative/v2/tutorials/prep-file4viewer/，而不是使用cURL发出请求，而是使用jquery编写了javascript代码来发出请求。我让每个请求都有一个函数，并有一个按钮来触发每个请求，如下代码所示。目前，除了转换到svf请求之外，每个请求都可以正常工作。当我试图发出该请求并检查请求的状态时，将打印以下消息：

    {
"urn": "dXJuOmFkc2sub2JqZWN0czpvcy5vYmplY3Q6cHJvamVjdGZpbGVzMTIzNC9fTUMtMTQwMDYlMjBGT0xERVIlMjBBU1NZJTIwLSUyMEhTQ0YtMTIuaWFtLmR3Zg",
"derivatives": [{
    "hasThumbnail": "false",
    "name": "_MC-14006 FOLDER ASSY - HSCF-12.iam.dwf",
    "progress": "complete",
    "messages": [{
        "type": "error",
        "code": "DWF2D-Not_A_DWF_Error",
        "message": "Unable to open, not a DWF/DWFx file."
    }, {
        "type": "error",
        "message": "Extractor error code -11",
        "code": "TranslationWorker-InternalFailure"
    }],
    "outputType": "svf",
    "status": "failed"
}],
"hasThumbnail": "false",
"progress": "complete",
"type": "manifest",
"region": "US",
"version": "1.0",
"status": "failed"

使用邮递员，我可以提出同样的要求，一切都会好的。然后，当我再次尝试翻译该文件时，只要它来自同一个桶，它就会工作。我需要文件能够立即从代码上传和翻译，而不必首先在邮递员中翻译。我甚至试图复制翻译请求的邮递员代码，但是当文件还没有在我的桶中时，我会收到同样的错误。下面是我的简单网页代码。

Answer 1

您的PUT没有指定文件名，只是指定了一个文件夹，所以上传可能已经损坏。另外，您不需要提供一个content-type。

文件必须由用户选择，您的浏览器应用程序不能访问本地文件夹结构。您可以创建一个input文件或form，然后将其传递给data字段。

    method: 'PUT',
    url:"https://developer.api.autodesk.com/oss/v2/buckets/"+encodeURIComponent(bucketKey)+"/objects/"+encodeURIComponent(fileName)+"",
    data: theForm.theInput.files[0],
    headers:{
        Authorization: "Bearer " + access_token
    },

您可以通过沙一签名验证您的下载，或者更简单地比较本地和现场的文件大小(在桶内)。
