self._cdescriptor = _message.default_pool.FindFieldByName(full_name) NameError: name '_message' is not defined

这个错误可能是由于没有正确地导入所需的模块或库而引起的。请确保您已经正确地导入了相关的模块，并且您正在使用所需的变量和函数。

如果您正在使用 Protocol Buffers，那么您需要导入相关的 proto 模块并确保您已经正确地定义了消息类型。您还需要使用 `protobuf` 库中的方法来对消息进行序列化和反序列化。

如果您能提供更多的上下文或代码示例，我可以更好地帮助您解决这个问题。

self._RpcMetricApiStub = RpcMetricApiStub(self._channel)

As an AI language model, I don't have access to the entire codebase and context surrounding this line of code, so I can only provide a general explanation.

This line of code creates a new instance of the `RpcMetricApiStub` class and assigns it to the `self._RpcMetricApiStub` variable. The `RpcMetricApiStub` class is likely defined in a separate module and provides an interface for making remote procedure calls (RPCs) to a metric API service.

The `self._channel` variable is likely a reference to a network communication channel, such as a socket or HTTP connection, that is used to send and receive RPC requests and responses. The `RpcMetricApiStub` class likely takes the communication channel as a parameter in its constructor, allowing it to use the channel to make RPC calls to the metric API service.

Overall, this line of code initializes a new instance of the `RpcMetricApiStub` class with a reference to the communication channel and assigns it to an instance variable for later use in the class.

> home_page = HomePage(self.driver) E NameError: name 'HomePage' is not defined

这个错误提示是因为 Python 找不到 `HomePage` 类的定义。你需要在当前文件或其他导入了当前文件的文件中定义 `HomePage` 类。

你可以在当前文件中定义 `HomePage` 类，例如：

class HomePage(BasePage):
    def __init__(self, driver):
        self.driver = driver

    # 定义其他方法

然后在 `Test_Login_method` 中导入 `HomePage` 类并使用，例如：

from path.to.HomePage import HomePage

class Test_Login_method(BasePage):
    def test01_login_method(self, user, passwd):
        self.get(LoginResources.URL_leons.value)
        self.send_keys(LoginResources.LOC_账号, user)
        self.send_keys(LoginResources.LOC_密码, passwd)
        self.click(LoginResources.LOC_管理员)
        self.click(LoginResources.LOC_登录按钮)

        # 获取登录后的页面
        home_page = HomePage(self.driver)
        return home_page

这样就可以使用 `HomePage` 类来返回登录后的页面了。
