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。

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：

 
# Filename : example.py

Response to GET request: 
 
 
     <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">

        function onRecaptcha(token) {
