Python Web表单提交

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。

 
# Filename : example.py# Copyright : 2020 By Aizws# Author by : www.aizws.net# Date : 2020-08-25import 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:

 
# Filename : example.py# Copyright : 2020 By Aizws# Author by : www.aizws.net# Date : 2020-08-25Response 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 >     .....................     .....................
