JMeter的下载以及安装使用

下载 

https://jmeter.apache.org/download_jmeter.cgi

安装

无须安装，解压之后即可使用。

解压到C:Program Filesapache-jmeter-5.1目录下(无法直接解压，先在D盘解压，然后复制到C盘里面)。

运行之后，一闪而过，没有出现UI。

需要注意的是:启动bat文件最好用管理员权限，否则我的使用路径是系统盘，会出现log文件不能写的问题

问题排查

注释掉jmeter.bat文件中的第一行，rem @echo off，然后运行如下命令，可以看到错误:

 解决:发现是lib文件夹没有复制成功导致的，之前复制文件夹的时候，提示lib被占用。所以没有复制成功。

PluginsManager

安装

https://jmeter-plugins.org/install/Install/

The easiest way to get the plugins is to install Plugins Manager. Then you'll be able to install any other plugins just by clicking a checkbox.

Download plugins-manager.jar and put it into lib/ext directory, then restart JMeter.  

 proxy

Plugins Manager respects JMeter's proxy settings. However, to avoid editing the properties files, we recommend to launch JMeter with additional parameters to pass it the proxy settings:

JVM_ARGS="-Dhttps.proxyHost=myproxy.com -Dhttps.proxyPort=8080" jmeterinjmeter.bat

If you need proxy username/password, specify them with two additional properties http.proxyUser and http.proxyPasslike this:

JVM_ARGS="-Dhttps.proxyHost=myproxy.com -Dhttps.proxyPort=8080 -Dhttp.proxyUser=john -Dhttp.proxyPass=***" jmeterinjmeter.bat

在system.properties文件中配置代理

So if you don't wish to set both http and https proxies, you can define the relevant properties in system.properties instead of using the command-line parameters.

https://stackoverflow.com/questions/52084212/how-to-manage-proxy-in-jmeter

You can configure JMeter to use proxy in 2 ways:

1. Command-line

   jmeter -H your_proxy_host -P your_proxy_port
   

2. Using system.properties (the file lives under "bin" folder of your JMeter installation, add the next lines to it:

   http.proxyHost=your_proxy_host
   http.proxyPort=your_proxy_port
   https.proxyHost=your_proxy_host
   https.proxyPort=your_proxy_port
   

   JMeter restart will be required to pick the properties up. 

 需要注意的是,http.proxyHost=http://    这里需要加http://

unable to find valid certification path to requested target

在jmeter.properties配置

# CookieManager behaviour - should Cookies be stored as variables?
# Default is false
CookieManager.save.cookies=true

407错误，代理需要授权

给代理配置上账户,这里的账号和密码。密码如果有特殊字符，需要先进行一次urlencode【密码中的@会被转换成%40】

 http://账号:密码@域名(ip):端口号

 总结

• 使用的proxy必须加上http://的前缀
• 使用的proxy必须配置账户和密码

         建议在bin system.properties文件末尾添加如下两行

          http.proxyHost=http://域账号:密码(url encode之后的) @proxy:port

         http.proxyPort=8080

• 导出https://jmeter-plugins.org/网站的证书

      参考https://blog.csdn.net/c5113620/article/details/80384660

• 将证书导入Java的证书验证系统(Java的证书验证系统是独立于操作系统和浏览器的，而是使用JRE中证书库，所有必须把代理工具的证书加入到JRE的证书库中。)
