import requests
def getHTMLText(url):
    try:
        r = requests.get(url, timeout=30)
        r.raise_for_status() # 如果状态不是200，引发HTTPError异常
        r.encoding = r.apparent_encoding
        return r.text
    except:
        return "error!"
if __name__ == "__main__":
    url = "http://www.baidu.com"
