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。
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:
Response to GET request: <!DOCTYPE html> <html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> <meta HTTP-EQUIV="Pragma" CONTENT="no-cache"> <meta HTTP-EQUIV="Expires" CONTENT="-1"> <title>Login - codepad</title> <link href="/main.css" media="screen" rel="stylesheet" type="text/css" /> <style type="text/css"> </style> <script src='https://www.google.com/recaptcha/api.js'></script> <script> function onRecaptcha(token) { document.getElementById("editor-form").submit(); } </script> </head> <body > ..................... .....................
