如何在 Jmeter 的 TCP 采样器中设置行尾字节值答案

【问题标题】：How to set End of Line byte value in TCP Sampler in Jmeter如何在 Jmeter 的 TCP 采样器中设置行尾字节值

【问题描述】：

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

【解决方案1】：

查看bytes read: 518 我希望您从正在测试的 TCP 服务器获得响应。

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。

将 Response Assertion 添加为失败的 TCP 采样器的子项
配置如下：
- 要测试的字段：Response Code
- 勾选Ignore Status框
- 模式匹配规则：Equals
- 要测试的模式：500
