这个函数是用来获取全部用户信息的。它调用了一个名为"user.list_all_users()"的函数,返回的结果会被封装到一个自定义的关键字返回结果result中,包括success、error、msg、response四个属性。如果成功获取到全部用户信息,success属性会被设置为True,并将返回结果封装到response属性中;如果获取失败,则会将success属性设置为False,并将错误信息封装到error和msg属性中。

python 安居客 爬虫_Python爬虫安居客房价信息(并利用百度地图API查询坐标)
好的,以下是爬取安居客房价信息并利用百度地图API查询坐标的Python爬虫代码:
```python
import requests
from bs4 import BeautifulSoup
import json
def get_location(city, address):
url = 'http://api.map.baidu.com/geocoder/v2/'
params = {
'address': address,
'city': city,
'output': 'json',
'ak': '你的百度地图API密钥'
}
res = requests.get(url, params=params)
json_data = json.loads(res.text)
if json_data['status'] == 0:
location = json_data['result']['location']
return location['lng'], location['lat']
def get_house_price(city, area):
url = 'https://{0}.anjuke.com/market/{1}/'.format(city, area)
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'}
res = requests.get(url=url, headers=headers)
soup = BeautifulSoup(res.text, 'lxml')
house_price_list = []
for tr in soup.select('.sale-estate-table tr')[1:]:
tds = tr.select('td')
house_name = tds[0].text.strip()
house_address = tds[1].text.strip()
house_price = tds[2].text.strip()
house_location = get_location(city, house_address)
if house_location:
house_price_list.append({
'name': house_name,
'address': house_address,
'price': house_price,
'location': house_location
})
return house_price_list
if __name__ == '__main__':
city = 'sh'
area = 'pudongxinqu'
house_price_list = get_house_price(city, area)
print(house_price_list)
```
其中,`get_location`函数用于利用百度地图API查询地址的坐标,`get_house_price`函数用于爬取安居客网站上的房价信息。在`if __name__ == '__main__'`中,我们可以指定城市和区域,通过调用`get_house_price`函数来获取该区域内的房价信息,并将结果打印出来。
注意:在使用本代码前请替换百度地图API密钥。
python爬取知乎数据_python集成代码实现八爪鱼爬取知乎的所有功能+外加数据预处理...
以下是Python爬取知乎数据的代码实现,其中使用了八爪鱼爬虫工具和数据预处理库pandas:
```python
import requests
import json
import pandas as pd
from octopus import Octopus
# 设置请求头信息
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36 Edge/16.16299'
}
# 构造请求url
def get_url(keyword, offset):
url = 'https://www.zhihu.com/api/v4/search_v3?t=general&q={}&correction=1&offset={}&limit=20&lc_idx=0&show_all_topics=0&search_hash_id='.format(keyword, offset)
return url
# 爬取知乎数据并保存为json文件
def crawl_data(keyword):
otto = Octopus(
concurrency=8, auto_start=True, expiration_in_seconds=120,
raise_all_exceptions=True, worker_lifespan_in_seconds=120
)
result = []
for i in range(0, 100, 20):
url = get_url(keyword, i)
otto.enqueue(get_data, url)
otto.wait()
for res in otto.results():
result += res
with open('zhihu.json', 'w', encoding='utf-8') as f:
json.dump(result, f, ensure_ascii=False)
# 解析json文件并使用pandas进行数据预处理
def process_data():
with open('zhihu.json', 'r', encoding='utf-8') as f:
data = json.load(f)
results = []
for item in data:
result = {}
result['问题'] = item['highlight']['title']
result['链接'] = 'https://www.zhihu.com/question/{}'.format(item['object']['question']['id'])
result['答案'] = item['highlight']['description']
results.append(result)
df = pd.DataFrame(results)
df.to_excel('zhihu.xlsx', index=False)
# 获取数据
def get_data(url):
response = requests.get(url, headers=headers)
data = response.json()['data']
result = []
for item in data:
if item['object']['type'] == 'answer':
result.append(item)
return result
if __name__ == '__main__':
crawl_data('Python')
process_data()
```
此代码实现了爬取知乎关于“Python”的数据,并将数据保存成json文件,再使用pandas进行数据预处理,最终将结果保存成Excel文件。你可以根据自己的需求修改关键词以及保存的文件格式。
