文件上传到 API 不适用于 JMeter 中的并发用户
File Upload to API is not working for concurrent user in JMeter
在我的一个场景中，我需要将文件上传到 API 并在 JMeter 中执行相同的操作。对于单用户设置，这个 API 可以正确执行。但是在尝试与并发用户执行相同的 API 时，我们遇到了异常。看起来同时有多个用户正在上传文件。所以我猜文件将进入只读模式。
谁能告诉我我的理解是否正确？以及在这种情况下我如何处理并发用户。我需要安排一些睡眠时间还是安排时间？
异常：{"version":"1.0.0.0","statusCode":500,"error":{"message":"Database operation expected to affect 1 row(s) but actually affected 0 row(s). Data may have been modified or deleted since entities were loaded. See http://go.microsoft.com/fwlink/?LinkId=527962 for information on understanding and handling optimistic concurrency exceptions.","code":"ARM_E_UNKNOWN"}}
好像是数据库并发冲突
The situation when another user has performed an operation that
conflicts with the current operation is known as concurrency conflict.
尽量给等待时间或使用多个上传文件。
