python - windows chrome通过命令行刷新选项卡0（或当前选项卡）

Question

我正在尝试使用python,webbrowser模块来做到这一点。但它没有Chromium特定的功能。还有其他方法吗？可能有一个批处理脚本？

我自己用这个：（我写得很快，因为它仅供个人使用）。通过大量清理，您可能会得到您想要的东西。请参阅https://developers.google.com/chrome-developer-tools/docs/remote-debugging

import urllib2
import urllib
import os
import subprocess
import json

from websocket import create_connection

def refresh_page(url):
    data = json.load(urllib2.urlopen('http://localhost:9222/json'))

    found_page = False
    for page in data:
        if page['url'].lower() == url.lower():
            found_page = True
            websocketURL = page['webSocketDebuggerUrl']
            ws = create_connection(websocketURL)

            obj = {  "id": 0,
                     "method": "Page.reload",
                     "params":
                     {
                       "ignoreCache": True,
                       "scriptToEvaluateOnLoad": ""
                     }
                  }

            dev_request = json.dumps(obj)
            ws.send(dev_request)
            result =  ws.recv()
            ws.close()
    if not found_page:
        raise Exception("No pageFound")

def open_or_refresh(file_name):
    file_name = "".join ( [f if f in r'\/:*?"<>|' else  urllib.quote(f) for f in file_name] )
    file_name = 'file:///' + file_name.replace('\\', '/')
    file_name = file_name.encode('ascii', 'ignore')
    try:
        refresh_page(file_name)
    except:
        cmd = (r'"%(LOCALAPPDATA)s\Google\Chrome\Application\chrome.exe"'%os.environ
               + r' --remote-debugging-port=9222  "%s"' % file_name)
        subprocess.Popen(cmd)
