Python Web表单提交
Python Web表单提交详细操作教程
通常，与网页的交互需要一些数据通过html页面中的表单提交给服务器。这些网络表单通常用于诸如注册新帐户或提供一些信息(例如姓名或卷号)以检索检查结果的过程。requests模块使用带有所需参数的POST方法优雅地处理此问题。
示例
在下面的示例中，我们通过提供用户名和密码值来使用网站的注册表单。提交值后，将打印响应的结果。

import requests
ID_USERNAME = 'signup-user-name'
ID_PASSWORD = 'signup-user-password'
USERNAME = 'username'
PASSWORD = 'yourpassword'
SIGNUP_URL = 'http://codepad.org/login'
def submit_form():
"""Submit a form"""
payload = {ID_USERNAME : USERNAME, ID_PASSWORD : PASSWORD,}
resp = requests.get(SIGNUP_URL)
print "Response to GET request: %s" %resp.content
resp = requests.post(SIGNUP_URL, payload)
print "Headers from a POST request response: %s" %resp.headers
#print "HTML Response: %s" %resp.read()
if __name__ == '__main__':
submit_form()
执行上面示例代码，得到类似下面结果：
