HOOK-ERROR in before_scenario: WebDriverException: Message: Authorization required

问题 {#heading}

你好大家，我正在尝试在BrowserStack上运行一些Appium测试。（我使用Python的Behave框架）

我遇到了以下问题：

项目结构的一部分：

• data
  -- credentials.yaml
  -- parameters.yaml

• helpers
  -- helpers.py

credentials.yaml内容：

browserstack:
  userName: "superduperusername"
  accessKey: "superduperaccesskey"

parameters.yaml内容：

browserstack_android:
  platformName: android
  framework: behave
  app: bs://roadtoeldorado
  platforms:
    - platformName: android
      deviceName: Samsung Galaxy S22 Ultra
      platformVersion: 12.0
  browserstackLocal: true
  buildName: bstack-demo
  projectName: BrowserStack Sample
  buildIdentifier: ${BUILD_NUMBER}
  debug: true
  networkLogs: true

helpers.py内容：

import pprint
from appium import webdriver
import yaml
def create_driver(driver_type):
# 从parameters.yaml中读取所需的能力
with open("data/parameters.yaml", "r") as parameters_file:
parameters = yaml.safe_load(parameters_file)
with open("data/credentials.yaml", "r") as credentials_file:
    credentials = yaml.safe_load(credentials_file)
if driver_type == 'local_android_emulator':
capabilities = parameters.get('local_android_emulator', {})
# 创建并返回本地驱动程序实例
return webdriver.Remote('http://localhost:4723/wd/hub', capabilities)
elif driver_type == 'browserstack_android':
capabilities = parameters.get('browserstack_android', {})
browserstack_config = credentials.get('browserstack', {})
capabilities.update({
**capabilities,
'browserstack.user': browserstack_config['userName'],
'browserstack.key': browserstack_config['accessKey'],
})
# 创建并返回BrowserStack驱动程序实例
pp = pprint.PrettyPrinter()
print("\n")
pp.pprint(capabilities)
return webdriver.Remote(
command_executor="https://hub-cloud.browserstack.com/wd/hub",
desired_capabilities=capabilities
)
else:
raise ValueError(f"不支持的驱动程序类型：{driver_type}")

打印的结果：

{'app': 'bs://roadtoeldorado',
 'browserstack.key': 'superduperkey',
 'browserstack.user': 'superduperusername',
 'browserstackLocal': True,
 'buildIdentifier': '${BUILD_NUMBER}',
 'buildName': 'bstack-demo',
 'debug': True,
 'framework': 'behave',
 'networkLogs': True,
 'platformName': 'android',
 'platforms': [{'deviceName': 'Samsung Galaxy S22 Ultra',
                'platformName': 'android',
                'platformVersion': 12.0}],
 'projectName': 'BrowserStack Sample'}

操作的结果：
在before_scenario钩子中出现错误：WebDriverException: Message: 需要授权

enviroment.py的内容：

import os
from helpers.helpers import create_driver
def before_scenario(context, scenario):
# 检查环境变量以设置执行模式
execution_mode = os.environ.get("EXECUTION_MODE", "local_android_emulator")
context.execution_mode = execution_mode
# 根据执行模式设置驱动程序
if context.execution_mode == "local_android_emulator":
context.driver = create_driver('local_android_emulator')
elif context.execution_mode == "browserstack_android":
context.driver = create_driver('browserstack_android')
else:
raise ValueError(f"不支持的执行模式：{execution_mode}")
# 根据需要添加更多模式
def after_scenario(context, scenario):
# 在所有场景完成后退出驱动程序
if hasattr(context, "driver") and context.driver:
context.driver.quit()

我几乎尝试了所有方法。尝试切换到JSON格式，调用JSON，但仍然没有解决问题（相同的错误）。我认为可能是没有正确传递能力，因为如果我尝试将凭据直接放在身份验证URL中，我会得到"missing deviceName"的错误。那么我做错了什么？ ? 英文:

So, hello everybody I'm trying to run some appium tests in browserstack. (I'm using behave with python)

So I have the following issue :

Part of the structure of the project:
-data
--credentials.yaml
--parameters.yaml

-helpers
--helpers.py

Content of credentials.yaml:

browserstack:
  userName: "superduperusername"
  accessKey: "superduperpaccesskey"

Content of parameters.yaml

browserstack_android:
  platformName: android
  framework: behave
  app: bs://roadtoeldorado
  platforms:
    - platformName: android
      deviceName: Samsung Galaxy S22 Ultra
      platformVersion: 12.0
  browserstackLocal: true
  buildName: bstack-demo
  projectName: BrowserStack Sample
  buildIdentifier: ${BUILD_NUMBER}
  debug: true
  networkLogs: true

Content of helpers.py

import pprint
from appium import webdriver
import yaml
def create_driver(driver_type):
Read desired capabilities from parameters.yaml based on driver_type
with open("data/parameters.yaml", "r") as parameters_file:
parameters = yaml.safe_load(parameters_file)
with open("data/credentials.yaml", "r") as credentials_file:
    credentials = yaml.safe_load(credentials_file)
if driver_type == 'local_android_emulator':
capabilities = parameters.get('local_android_emulator', {})
# Create and return the local driver instance
return webdriver.Remote('http://localhost:4723/wd/hub', capabilities)
elif driver_type == 'browserstack_android':
capabilities = parameters.get('browserstack_android', {})
browserstack_config = credentials.get('browserstack', {})
capabilities.update({
**capabilities,
'browserstack.user': browserstack_config['userName'],
'browserstack.key': browserstack_config['accessKey'],
})
# Create and return the BrowserStack driver instance
pp = pprint.PrettyPrinter()
print("\n")
pp.pprint(capabilities)
return webdriver.Remote(
command_executor="https://hub-cloud.browserstack.com/wd/hub",
desired_capabilities=capabilities
)
Add more cases for other driver types if needed
else:
raise ValueError(f"Unsupported driver type: {driver_type}")

The result from the print:

{'app': 'bs://roadtoeldorado',
 'browserstack.key': 'superduperkey',
 'browserstack.user': 'superduperusername',
 'browserstackLocal': True,
 'buildIdentifier': '${BUILD_NUMBER}',
 'buildName': 'bstack-demo',
 'debug': True,
 'framework': 'behave',
 'networkLogs': True,
 'platformName': 'android',
 'platforms': [{'deviceName': 'Samsung Galaxy S22 Ultra',
                'platformName': 'android',
                'platformVersion': 12.0}],
 'projectName': 'BrowserStack Sample'}

The result from the operation :
HOOK-ERROR in before_scenario: WebDriverException: Message: Authorization required

Contents of the enviroment.py

import os
from helpers.helpers import create_driver
def before_scenario(context, scenario):
Check for the environment variable to set the execution mode
execution_mode = os.environ.get("EXECUTION_MODE", "local_android_emulator")
context.execution_mode = execution_mode
Set up the driver based on execution mode
if context.execution_mode == "local_android_emulator":
context.driver = create_driver('local_android_emulator')
elif context.execution_mode == "browserstack_android":
context.driver = create_driver('browserstack_android')
else:
raise ValueError(f"Unsupported execution mode: {execution_mode}")
Add more modes as needed
`def after_scenario(context, scenario):
Quit the driver after all scenarios have finished
if hasattr(context, "driver") and context.driver:
context.driver.quit()
`

Pretty much tried everything. Changing to JSON format, calling the JSON, but still nothing (same error). I'm thinking that probably I'm not passing properly the capabilities, because if I try to put the credentials directly to the url for authentication, I'm getting "missing deviceName." So what am I doing wrong?

请将您的代码中的hub URL更改为以下Basic Auth格式：

"https://YOUR_BSTACK_USERNAME:BSTACK_ACCESS_KEY@hub-cloud.browserstack.com/wd/hub" 英文:

In your code, could you please change the hub URL to the below Basic Auth format:

"https://YOUR_BSTACK_USERNAME:BSTACK_ACCESS_KEY@hub-cloud.browserstack.com/wd/hub"
