如何使用机器人框架和硒读取 Web 控制台输出? [英] How to read the web console output with robot framework and selenium?

问题描述

我正在尝试读取网页的控制台输出，尤其是我需要使用 RF 和 Selenium 进行 POST-GET-PUT ajax 调用.我在网上找到了一些帮助，但我似乎无法让它工作.我拥有的python脚本是:

I am trying to read the console output of a webpage, especially I need the POST-GET-PUT ajax calls, with RF and Selenium. I have found some help online but I cannot seem to make it work. the python script I have is:

from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

def get_logs2(driver):
# enable browser logging
    #d = DesiredCapabilities.CHROME
    #d['goog:loggingPrefs'] = { 'browser':'ALL' }
    #driver = webdriver.Chrome(desired_capabilities=d)

    # load the desired webpage
    #driver.get(driver.current_url)
    a = driver.get_log('browser')

    # print messages
    for entry in driver.get_log('browser'):
        print(entry)
    print("finished")
    return a

在网页上做了一些操作后，我从 RF 调用了这个脚本.所以我需要向这个函数传递我采取的行动之后的页面.要做到这一点，我会这样做:

I call this script from RF, after having done some operations on the webpage. So I need to pass to this function the page exactly how it is after the actions I took. To do that I do:

    ${seleniumlib}=    Get Library Instance    SeleniumLibrary
    Log    ${seleniumlib._drivers.active_drivers}[0]
    ${message} =    Get Logs2   ${seleniumlib._drivers.active_drivers}[0]

我得到的结果是空消息，但我知道控制台不是空的.你能帮我吗?谢谢.

I get as a result and empty message, but I know console is not empty. Can you help? Thanks.

推荐答案

这是一个完全使用 Robot Framework 的解决方案，没有额外的用户库.逻辑是一样的.

Here is a solution using entirely Robot Framework, no additional user library. The logic is the same.

1. 设置正确的浏览器功能以启用日志记录.
2. 然后使用 Get Library Instance 关键字来检索 webdriver 实例.
3. 调用 webdriver 实例上的 get_log('browser').

1. Set the correct browser capabilities to enable logging.
2. Then use the Get Library Instance keyword to retrieve the webdriver instance.
3. Call the get_log('browser') on the webdriver instance.
