git clone [email protected]:djytwy/pyspider.git

cd ./pyspider

npm install

pip install -r requirements.txt

python run.py

Any APIs in pyspider could be used normally in this project.

To control chromeheadless add some params in self.crawl: launch chromeheadless to crawl web page (fetch_type="chrome" or fetch_type="chromium"):

def on_start(self):
    self.crawl('http://www.example.org/', callback=self.callback,fetch_type="chrome")

device (string): this param can control chromeheadless launch in mobile devices(eg:"iphone 6"):

def on_start(self):
    self.crawl('http://www.example.org/', callback=self.callback,fetch_type="chrome",device="iphone 6")

headless(bool default false): this param can control chromeheadless whether launch in headless mode (tested only on Windows 10 and MacOS):

def on_start(self):
    self.crawl('http://www.example.org/', callback=self.callback,fetch_type="chrome",headless=False)

Waring: headless only use in debug mode and in visual browser(eg: windows 10 and MacOS) for product environment please set it false.And browser launch only once in pyspider.
