JMeter - HTTP 请求的默认连接和响应超时是多少

Question

Jmeter 中 HTTP 请求的默认连接和响应超时是多少？

我没有更改jmeter.properties文件中的任何设置。

# set the socket timeout (or use the parameter http.socket.timeout)
# for AJP Sampler implementation.
# Value is in milliseconds
#httpclient.timeout=0
# 0 == no timeout

# Idle connection timeout (Milliseconds) to apply if the server does not send
# Keep-Alive headers (default 0)
# Set this > 0 to compensate for servers that don't send a Keep-Alive header
# If <= 0, idle timeout will only apply if the server sends a Keep-Alive header
#httpclient4.idletimeout=0

# Polling to see if process has finished its work, used when a timeout is configured on sampler
#os_sampler.poll_for_timeout=100

展望JMeter 5.1 源代码：

public int getConnectTimeout() {
    return getPropertyAsInt(CONNECT_TIMEOUT, 0);
}

public void setResponseTimeout(String value) {
    setProperty(RESPONSE_TIMEOUT, value, "");
}

public int getResponseTimeout() {
    return getPropertyAsInt(RESPONSE_TIMEOUT, 0);
}

默认值为，0表示“无超时”，因此 JMeter 将永远等待连接/响应。因此，为了安全起见，我建议使用以下方法定义合理的超时：HTTP 请求默认值
