上传 1GB 文件时的 JMeter SocketException

Question

JMeter 5.4.1 OpenJDK 15.0.1

我的测试服务器默认配置为允许上传最大 1073741824 字节的文件，这是一个可配置的限制。我的目标是验证配置的限制是否得到遵守。

当我将它配置为 1048576 字节并超过我的上传限制时，服务器发送响应：

"{"type":"https://tools.ietf.org/html/rfc7231#section-6.5.1","title":"One or more validation errors occurred.","status":400,"traceId":"|bd37f36b-4cd68e1b8b433669.","errors":{"":["Failed to read the request form. Multipart body length limit 1048576 exceeded."]}}"

当我将它配置为 1073741824 字节并超过我的上传限制时，JMeter 报告以下错误：

我的 JMeter.bat 文件的堆设置如下：

set HEAP=-Xms1g -Xmx4g -XX:MaxMetaspaceSize=256m

这看起来类似于去年 10 月的 post，但没有解决方案 suggested/reported。 SocketException after sending huge request via JMeter

Answer 1

Connection reset by peer 表示您的服务器已重置连接，因此您应该在服务器日志中寻找线索。

我建议在 JMeter 方面做的唯一一件事是考虑切换到 JMeter 插件支持论坛上的 HTTP Raw Request sampler, it has nice feature of streaming the file directly to the server without loading it to memory first, I think you will find it extremely helpful when it comes to load testing with more than one virtual user. See HTTP Raw Request for SOAP + MTOM post 以获取更多详细信息。
