添加adsk3LeggedToken时Revit设计自动化出现下载失败错误求助

问题描述 #

• 向Design Automation提交工作项时，添加adsk3LeggedToken参数会触发下载失败错误；不添加该参数时，文件可成功下载并启动脚本，但运行脚本时会出现认证问题
• 使用SaveAsCloudModel() API，对应的bundle已在Revit API（非Design Automation环境）中验证可正常运行，当前通过Postman发起请求

工作项请求内容 #

{
  "activityId": "SAVE_CLOUD_MODEL.SaveModelTestActivity8+current",
  "arguments": {
    "rvtFile": {
      "verb": "get",
      "url": "/* INPUT URL (TESTED AND WORKS) */",
      "pathInZip": "/* WORKING PATH */"

  }
}

解决方法 #

经排查，问题根源在于Token类型错误：此前误将2Legged Token当作3Legged OAuth Token传入adsk3LeggedToken参数。更换为正确的3Legged OAuth Token后，工作项可正常运行，下载失败与认证问题均得到解决。
