美空网数据----爬虫数据存储
确定了爬虫的目标，接下来，我做了两件事情，看一下，是否对你也有帮助
- 确定数据存储在哪里？最后我选择了MongoDB
- 用正则表达式去分析网页数据
引入必备模块
import requests #网络请求模块
import random #随机模块
import re #正则表达式模块
import time #时间模块
import threading #线程模块
import pymongo as pm #mongodb模块
接下来，我们需要准备一个通用函数模拟UserAgent做一个简单的反爬处理
class Config():
def getHeaders(self):
user_agent_list = [ \

]
UserAgent=random.choice(user_agent_list)
headers = {'User-Agent': UserAgent}
return headers
编写生产者的类和核心代码,Producer继承threading.Thread
#生产者
class Producer(threading.Thread):
def run(self):
print("线程启动...")
headers = Config().getHeaders()
if __name__ == "__main__":
p = Producer()
p.start()
测试运行，一下，看是否可以启动
[linuxboy@bogon moocspider]$ python3 demo.py
线程启动...
{'User-Agent': 'Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/535.24 (KHTML, like Gecko) Chrome/19.0.1055.1 Safari/535.24'}
[linuxboy@bogon moocspider]$
如果上面的代码没有问题，接下来就是我们爬虫代码部分了，为了方便多线程之间的调用，我们还是创建一个共享变量在N个线程之间调用
import requests
import random
import re
import time
import threading
import pymongo as pm
# 获取连接
client = pm.MongoClient('localhost', 21111) # 端口号是数值型
# 连接目标数据库
db = client.moko
# 数据库用户验证
db.authenticate("moko", "moko")
urls = ["http://www.moko.cc/subscribe/chenhaoalex/1.html"]
index = 0 #索引
g_lock = threading.Lock() #初始化一个锁
#生产者
class Producer(threading.Thread):
def run(self):
print("线程启动...")
headers = Config().getHeaders()
print(headers)
global urls
global index
while True:
g_lock.acquire()
if len(urls)==0:
g_lock.release()
continue
page_url = urls.pop()
g_lock.release() #使用完成之后及时把锁给释放，方便其他线程使用
response = ""
try:
response = requests.get(page_url,headers=headers,timeout=5)
except Exception as http:
print("生产者异常")
print(http)
continue
content = response.text
rc = re.compile(r'<a class=\"imgBorder\" href=\"\/(.*?)\" hidefocus=\"true\">')
follows = rc.findall(content)
print(follows)
fo_url = []
threading_links_2 = []
for u in follows:
this_url = "http://www.moko.cc/subscribe/%s/1.html" % u
g_lock.acquire()
index += 1
g_lock.release()
fo_url.append({"index":index,"link":this_url})
threading_links_2.append(this_url)
g_lock.acquire()
urls += threading_links_2
g_lock.release()
print(fo_url)
try:
db.text.insert_many(fo_url,ordered=False )
except:
continue
if __name__ == "__main__":
p = Producer()
p.start()
上面代码除了基本操作以外，我做了一些细小的处理
