Question

我正在尝试使用browsermob-proxy来监视硒测试的所有请求和响应。就我而言，我正在selenium上py.test图像内的docker框架中运行jenkins测试。我正在使用以下版本：

selenium == 3.8.0
pyvirtualdisplay == 0.2.1
pytest == 3.4.0
browsermob-proxy == 0.8.0

也是Java openjdk-8-jdk。

在py.test代码中，我具有以下行来创建和启动服务器：

proxyserver =  Server(
           path="/root/tests/bsp_usecase_tests/bin/browsermob-proxy",
           options={'port': 8090}
       )
proxyserver.start()
driverproxy = proxyserver.create_proxy() # line 127

但在最后一行中，出现以下错误：

conftest.py:127: in basedriver
    driverproxy = proxyserver.create_proxy()
/usr/local/lib/python2.7/dist-packages/browsermobproxy/server.py:40: in create_proxy
    client = Client(self.url[7:], params)
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 

self = <browsermobproxy.client.Client object at 0x7f1a5f73f1d0>
url = 'localhost:8090', params = {}, options = {}

    def __init__(self, url, params=None, options=None):
        """
            Initialises a new Client object


            :param url: This is where the BrowserMob Proxy lives
            :param params: URL query (for example httpProxy and httpsProxy vars)
            :param options: Dictionary that can contain the port of an existing
                            proxy to use (for example 'existing_proxy_port_to_use')
            """
        params = params if params is not None else {}
        options = options if options is not None else {}
        self.host = "http://" + url
        if params:
            urlparams = "?" + unquote(urlencode(params))
        else:
            urlparams = ""
        if 'existing_proxy_port_to_use' in options:
            self.port = options['existing_proxy_port_to_use']
        else:
            resp = requests.post('%s/proxy' % self.host + urlparams)
            content = resp.content.decode('utf-8')
            try:
                jcontent = json.loads(content)
            except Exception as e:
                raise Exception("Could not read Browsermob-Proxy json\n"

/usr/local/lib/python2.7/dist-packages/browsermobproxy/client.py:37: Exception

也许我忘记了将重要文件复制到Docker映像中吗？

我为browsermob-proxy进行了以下设置（除了安装pip之外）：

bsp_usecase_tests/bin:
browsermob-proxy

bsp_usecase_tests/lib:
browsermob-dist-2.1.4.jar

即我已将文件browsermob-proxy复制到bin并将文件browsermob-dist-2.1.4.jar复制到lib文件夹中。另外，服务器本身似乎正在启动并正在运行。但是，当我尝试获取可用于selenium驱动程序的代理信息时，出现了这个奇怪的错误。

有什么想法我做错了什么，或者缺少什么？

在我看来，该端口已在使用中。您可以使用lsof检查端口是否正在使用中，然后将其杀死（如果正在使用中）。您可以使用lsof -i:8090

编辑：您已经在此线程中完成了此操作- How to fix 'Address already in use' error with browsermob-proxy?

我将使用来初始化服务器

proxyserver =  Server(
       path="/root/tests/bsp_usecase_tests/bin/browsermob-proxy",
       options={'existing_proxy_port_to_use': 8090})

这应该做到。

Browsermob-Proxy中的内部代码正在寻找名为'options'的{{1}}字典中的密钥，否则它将使用默认的即空字典。

如何修复“无法读取Browsermob-Proxy json”？
