JMeter va.net.ConnectException: Connection refused (Connection refused)

JMeter va.net.ConnectException: Connection refused (Connection refused)

场景

Jmeter接口测试发生的错误,paw、postman、浏览器直接访问都可以,jmeter线程组测试HTTP请求就是过不去~~

Error Code

解决方法

修改"HTTP请求"Advanced ——> Client implementation ——> implementation ——> Java即可;

建议

将此设置配置在 HTTP Request Defaults中,如果想使用HttpClient4时直接更改,默认是这个~~~
