为什么我在导出 API 调用时收到来自 CopyLeaks 的"conflict" HTTP 409 响应？

Question

我得到一个HTTP 409"冲突；在处理CopyLeaks的"响应"时；"完成"；发送导出请求时使用webhook。我今天每次提交测试扫描时都会收到它，但几天前我上次测试代码时没有收到。每次新扫描我都会得到它。回复没有正文，也没有更多信息。知道是什么原因导致的吗？如何解决？

以下是一些调试信息：扫描API请求主体：

并且没有响应机构。

Answer 1

每个导出任务都有其唯一的任务id。使用请求的id创建作业后，就无法使用相同的id创建另一个导出作业。

话虽如此，如果您遇到错误409，我假设您正在尝试导出具有相同作业id的多个任务。

为了提交唯一的导出Id，您必须将URI更改为以下形式：

https://api.copyleaks.com/v3/downloads/scanId/export/UNIQUE_JOB_ID

并为您创建的每个新导出作业设置一个UNIQUE_JOB_ID。
