如何从Selenium Webdriver Firefox中的driver.page_source获取HTTP请求的原始JSON响应

selenium

如果浏览到，https://httpbin.org/headers我希望得到以下JSON响应：

{
  "headers": {
    "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8", 
    "Accept-Encoding": "gzip, deflate, br", 
    "Accept-Language": "en-US,en;q=0.5", 
    "Connection": "close", 
    "Host": "httpbin.org", 
    "Upgrade-Insecure-Requests": "1", 
    "User-Agent": "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:64.0) Gecko/20100101 Firefox/64.0"
  }
}

但是，如果我使用selenium

from selenium import webdriver
from selenium.webdriver.firefox.options import Options

options = Options()
options.headless = True
driver = webdriver.Firefox(options=options)

url = 'https://httpbin.org/headers'
driver.get(url)
print(driver.page_source)
driver.close()

我懂了

<html platform="linux" class="theme-light" dir="ltr"><head><meta http-equiv="Content-Security-Policy" content="default-src 'none' ; script-src resource:; "><link rel="stylesheet" type="text/css" href="resource://devtools-client-jsonview/css/main.css"><script type="text/javascript" charset="utf-8" async="" data-requirecontext="_" data-requiremodule="viewer-config" src="resource://devtools-client-jsonview/viewer-config.js"></script><script type="text/javascript" charset="utf-8" async="" data-requirecontext="_" data-requiremodule="json-viewer" src="resource://devtools-client-jsonview/json-viewer.js"></script></head><body><div id="content"><div id="json">{
  "headers": {
    "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8", 
    "Accept-Encoding": "gzip, deflate, br", 
    "Accept-Language": "en-US,en;q=0.5", 
    "Connection": "close", 
    "Host": "httpbin.org", 
    "Upgrade-Insecure-Requests": "1", 
    "User-Agent": "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:64.0) Gecko/20100101 Firefox/64.0"
  }
}
</div></div><script src="resource://devtools-client-jsonview/lib/require.js" data-main="resource://devtools-client-jsonview/viewer-config.js"></script></body></html>

除了原始JSON响应外，driver.page_source还包含HTML以在浏览器中“漂亮地打印”响应。如果使用Firefox DOM和Style
Inspector在浏览器中查看JSON响应的源，您将得到相同的结果。

要获取原始JSON响应，您可以照常浏览HTML元素：

print(driver.find_element_by_xpath("//div[@id='json']").text)
