tcp - 如何在 Jmeter 的 TCP 采样器中设置行尾字节值

Question

使用 TCP 采样器时出现 ReadException。

   "Response message: org.apache.jmeter.protocol.tcp.sampler.ReadException: 
    Error reading from server, bytes read: 518"

我正在尝试使用 TCP 采样器测试一些响应，但无法确定必须设置的行尾字节值。

预计会看到来自服务器的响应数据的 200 响应代码。但是接收到正确的响应数据与“

Response code: 500
Response message: org.apache.jmeter.protocol.tcp.sampler.ReadException: Error reading from server, bytes read: 518

作为响应代码和消息”

尝试使用以下设置

Re-use Connection--Yes
Close Connection--Yes
Set No Delay--No
SO_LINGER-Blank
End of Line: 128

Answer 1

bytes read: 518调查我希望你得到你正在测试的 TCP 服务器的响应。

如果服务器强制关闭连接并且您期望这种行为，您可以“告诉”JMeter 将 TCP 采样器视为成功。

1. 添加响应断言作为失败的 TCP 采样器的子项

2. 配置如下：

   • 测试领​​域：Response Code
   • 勾选Ignore Status框
   • 模式匹配规则：Equals
   • 要测试的模式：500
