pyppeteer拦截器使用

# 设置request拦截器
await page.setRequestInterception(True) # 设置request拦截器，想对请求作修改需要加这句
page.on('request',lambda req: asyncio.ensure_future(intercept_request(req)))
# 设置response拦截器
page.on('response',lambda rep: asyncio.ensure_future(intercept_response(rep)))
​
# 请求拦截器函数，设置拦截条件并可作修改
async def intercept_request(interceptedRequest):
    if 'xxx' in interceptedRequest.url:
        await interceptedRequest.continue_({"url": "xxx"}) # 修改url为xxx
    else:
      await interceptedRequest.continue_()

​
# 响应拦截器函数，设置拦截条件并可作修改
async def intercept_response(interceptedResponse):
    if 'xxx' in interceptedResponse.url:
        response = await interceptedResponse.text() # 获得请求的text内容
