开发Appium Plugin时console.log无法输出至终端的问题

问题概述 #

我正在开发一款Appium插件，开发过程中尝试调用console.log()，期望传入的字符串能显示在加载该插件的Appium Server启动终端窗口中，但实际这些字符串并未出现在服务器日志里。我认为自己遗漏了某个简单配置，目前没有相关文档说明，而日志输出对开发至关重要。

插件代码 #

import BasePlugin from '@appium/base-plugin';
import type { BaseDriver } from 'appium/driver';
type NextHandler = () => Promise<string>;
export declare function customLogger(message: string): void;
export declare class MyApp extends BasePlugin {
    getPageSource(next: NextHandler, driver: BaseDriver<any>): Promise<import("my-app").Results>;
}
export {};

import BasePlugin from '@appium/base-plugin'
import type { BaseDriver } from 'appium/driver'
import myPlugin from '@my-plugin/appium-engine'
import axios from 'axios'
import * as fs from 'fs';
import * as path from 'path';

type NextHandler = () => Promise<string>

export class MyApp extends BasePlugin {
  public async getPageSource(next: NextHandler, driver: BaseDriver<any>) {
    // 这是我们在capabilities中设置的API密钥
    const apiKey = driver.caps.key
    const originalSource = await next()
    console.log("My console log")
    const results = myPlugin(originalSource)

    // 将数据发送到服务器
    const { data } = await axios.post(
      'http://localhost:3001/api/scans',
      { scan: results },
      {
        headers: {
          'Content-Type': 'application/json',
          'x-auth-token': apiKey
        }
      }
    )

    return results
  }
}

客户端代码 #

from appium import webdriver
from appium.options.ios import XCUITestOptions
from appium.webdriver.appium_connection import AppiumConnection

class CustomAppiumConnection(AppiumConnection):
    # 可为自定义类添加方法
    pass

custom_executor = CustomAppiumConnection(remote_server_addr='http://0.0.0.1:1234')

options = XCUITestOptions().load_capabilities({
    'platformVersion': '16.2',
    'deviceName': 'iPhone 14',
    'udid': '450B76CF-CF54-4DBC-90E5-FC4E567EF52C',
    'key': 'value'
})
driver = webdriver.Remote(custom_executor, options=options)
pageSource = driver.page_source

启动服务器命令 #

appium --use-plugins @my-plugin/appium-plugin --log-level debug

WebDriver文档参考 #

@property
    def page_source(self) -> str:
        """获取当前页面的源码

        使用示例:
            ::

                driver.page_source
        """
        return self.execute(Command.GET_PAGE_SOURCE)["value"]

GET_PAGE_SOURCE: str = "getPageSource"

已尝试的解决方法 #

• 重新构建项目
• 尝试将日志写入文件（已引入import * as fs from 'fs';等相关模块）
