爬虫第5课:POST请求
在Python中,我们可以使用requests库来发送POST请求。以下是一些示例:
- 使用数据字典发送POST请求:
import requests
url = 'http://httpbin.org/post'
data = {'key': 'value'}
response = requests.post(url, data=data)
print(response.text)
- 使用json文件发送POST请求:
import requests
url = 'http://httpbin.org/post'
filename = 'data.json'
with open(filename, 'r') as f:
data = f.read()
response = requests.post(url, data=data)
print(response.text)
- 使用json数据直接发送POST请求:
import requests
url = 'http://httpbin.org/post'
data = {'key': 'value'}
response = requests.post(url, json=data)
print(response.text)
- 发送带有headers的POST请求:
import requests
url = 'http://httpbin.org/post'
data = {'key': 'value'}
headers = {'User-Agent': 'my-app/0.0.1'}
response = requests.post(url, data=data, headers=headers)
print(response.text)
- 发送带有cookies的POST请求:
import requests
url = 'http://httpbin.org/post'
data = {'key': 'value'}
cookies = {'cookie_key': 'cookie_value'}
response = requests.post(url, data=data, cookies=cookies)
print(response.text)
- 发送multipart/form-data类型的POST请求:
import requests
url = 'http://httpbin.org/post'
data = {'file': open('report.xls', 'rb')}
response = requests.post(url, files=data)
print(response.text)
以上就是一些使用Python的requests库发送POST请求的示例。在实际应用中,你可以根据你的需求选择合适的方法。
