httpclient使用HTTP代理实践

2020-08-19 14:46:12 浏览数 (1)

最近在做测试的时候遇到一个问题:就是内部网络做了限制,「部分服务只有在机房的网段内才能访问」

虽然不清楚具体原因,不过的确给测试造成了一些麻烦,使用工具或者Git进行文件同步的话,虽然可行,但总归不是那么方便。再加上一些功能测试工具选择的问题,对我来讲添加了更多的麻烦。不过这倒是更有利于我的性能测试方案实施,具体情况如下:如何在Linux命令行界面愉快进行性能测试。

所以想到了在Java中使用proxy配置,然后通过在机房开发机中配置一个HTTP代理,然后本机请求从proxy配置得到一个代理服务器地址,然后绕去内网访问服务,这样就完美解决了这个方案。

public static void main(String[] args) {
        def get = getHttpPost("http://ip-api.com/json/?lang=zh-CN ")
        def response1 = getHttpResponse(get)
        output(response1)
        setProxy(get,"104.129.198.211:10605")
        def response = getHttpResponse(get)
        output(response)


        testOver()
    }

控制台输出:
