C# Revit Addin设计自动化请求上传失败（504网关超时）求助

我们的C# Revit插件调用Design Automation时，任务因failedUpload状态失败，核心问题是上传处理后的Revit结果文件时触发504网关超时，完整执行日志如下：

排查与解决建议 #

• 改用分块上传：上传文件大小约818MB，单次PUT请求容易触发超时。Autodesk OSS API支持分块上传，将文件拆分为50MB左右的小块分别上传，最后合并成完整文件，能大幅降低超时概率。
• 清理文件名特殊字符：当前上传文件名包含空格，可能引发网关解析异常，建议替换为下划线或连字符，例如20220908164214_1305-Interior_purged.rvt。
• 优化重试策略：现有重试逻辑未采用指数退避，可调整为1s、2s、4s、8s的间隔重试，同时增加重试次数上限；上传前确认token有效期，避免上传过程中token失效。
• 匹配服务区域：检查OSS桶generatedmodels的存储区域，确保与Design Automation任务执行区域一致，减少跨区域传输延迟。
• 确认服务状态：临时的Autodesk服务波动也可能导致超时，可通过官方渠道确认服务是否正常。
