如何修复 pyppeteer.errors.NetworkError: Request interception is not enabled.

English Deutsch 简体中文

*注意：*另请参见Pyppeteer 最小网络请求拦截示例

问题：

你正在尝试使用以下命令在 Pyppeteer 中拦截请求

pyppeteer_request_interception_enable.py
page.on('request', my_intercept_request)

但你得到类似这样的错误消息：

pyppeteer_traceback.txt
Traceback (most recent call last):
  File "/usr/lib/python3.6/asyncio/events.py", line 145, in _run
    self._callback(*self._args)
  File "/usr/local/lib/python3.6/dist-packages/pyee/_compat.py", line 62, in _callback
    self.emit('error', exc)
  File "/usr/local/lib/python3.6/dist-packages/pyee/_base.py", line 106, in emit
    self._emit_handle_potential_error(event, args[0] if args else None)
  File "/usr/local/lib/python3.6/dist-packages/pyee/_base.py", line 83, in _emit_handle_potential_error
    raise error
  File "run.py", line 6, in intercept
    await request.continue_()
  File "/usr/local/lib/python3.6/dist-packages/pyppeteer/network_manager.py", line 481, in continue_
    raise NetworkError('Request interception is not enabled.')
pyppeteer.errors.NetworkError: Request interception is not enabled.

解决方案

添加

enable_request_interception_fix.py
await page.setRequestInterception(True)

直接在你调用

enable_request_interception.py
page = await browser.newPage()

这将启用请求拦截，你的代码将正常运行。
