selenium-webdriver – Selenium Remote Webdriver提供JSONDecodeError

概述我的代码： import unittestfrom selenium import webdriverfrom selenium.webdriver.common.desired_capabilities import DesiredCapabilitiesfrom selenium.webdriver.common import desired_capabilitiesclass te 我的代码：

import unittestfrom selenium import webdriverfrom selenium.webdriver.common.desired_capabilitIEs import DesiredCapabilitIEsfrom selenium.webdriver.common import desired_capabilitIEsclass test_mycode(unittest.TestCase):    def setUp(self):        desired_cap = {'browser': 'IE','browser_version': '8.0','os': 'windows','os_version': '7','resolution': '1366x768'}        self.driver = webdriver.Remote(command_executor='http://user@R_419_6889@:[email protected]:80/wd/hub',desired_capabilitIEs=desired_cap)    def test_website(self):        .....

错误是：

Traceback (most recent call last):file "C:\Workspace\Pumpkin Patch Website\test cases\_test_mycode.py",line 55,in setUp    desired_capabilitIEs=desired_cap)file "C:\Users\elton.tiong\AppData\Local\Programs\Python\python35-32\lib\site-packages\selenium-2.48.0-py3.5.egg\selenium\webdriver\remote\webdriver.py",line 87,in __init__    self.start_session(desired_capabilitIEs,browser_profile)file "C:\Users\elton.tiong\AppData\Local\Programs\Python\python35-32\lib\site-packages\selenium-2.48.0-py3.5.egg\selenium\webdriver\remote\webdriver.py",line 141,in start_session    'desiredCapabilitIEs': desired_capabilitIEs,file "C:\Users\elton.tiong\AppData\Local\Programs\Python\python35-32\lib\site-packages\selenium-2.48.0-py3.5.egg\selenium\webdriver\remote\webdriver.py",line 201,in execute    self.error_handler.check_response(response)file "C:\Users\elton.tiong\AppData\Local\Programs\Python\python35-32\lib\site-packages\selenium-2.48.0-py3.5.egg\selenium\webdriver\remote\errorhandler.py",line 102,in check_response    value = Json.loads(value_Json)file "C:\Users\elton.tiong\AppData\Local\Programs\Python\python35-32\lib\Json\__init__.py",line 319,in loads    return _default_decoder.decode(s)file "C:\Users\elton.tiong\AppData\Local\Programs\Python\python35-32\lib\Json\decoder.py",line 339,in decode    obj,end = self.raw_decode(s,IDx=_w(s,0).end())file "C:\Users\elton.tiong\AppData\Local\Programs\Python\python35-32\lib\Json\decoder.py",line 357,in raw_decode    raise JsONDecodeError("Expecting value",s,err.value) from NoneJson.decoder.JsONDecodeError: Expecting value: line 1 column 1 (char 0)

selenium-server-standalone2.48.0已安装并正在运行.

Python是3.5

这是我写的在browserstack上运行Selenium的代码.我遵循browserstack给出的指令,但是,当我运行它时,它引发了JsONDecodeError.

我还将command_executor更改为http://127.0.0.1:4444/wd/hub但它失败了.然后我将desire_capabilitIEs = desired_cap更改为desired_capabilitIEs.DesireCapabilitIEs.firefox但它也失败了.

我在谷歌搜索,但找不到任何答案.有人可以帮忙吗？非常感谢你.

解决方法 我知道这已经2岁了,但是由于没有人回答,希望这会对其他人有所帮助. desired_cap中的值基本上是无效的Json.为了确认,我对 https://jsonlint.com/进行了测试.

修复很简单 – 将所有单引号替换为双引号：

desired_cap = {'browser': 'IE','resolution': '1366x768'}desired_cap = desired_cap.replace('\'','\"')
