pyppeteer攔截器使用

# 設置request攔截器
await page.setRequestInterception(True) # 設置request攔截器，想對請求作修改需要加這句
page.on('request',lambda req: asyncio.ensure_future(intercept_request(req)))
# 設置response攔截器
page.on('response',lambda rep: asyncio.ensure_future(intercept_response(rep)))
​
# 請求攔截器函數，設置攔截條件並可作修改
async def intercept_request(interceptedRequest):
    if 'xxx' in interceptedRequest.url:
        await interceptedRequest.continue_({"url": "xxx"}) # 修改url為xxx
    else:
      await interceptedRequest.continue_()

​
# 響應攔截器函數，設置攔截條件並可作修改
async def intercept_response(interceptedResponse):
    if 'xxx' in interceptedResponse.url:
        response = await interceptedResponse.text() # 獲得請求的text內容
