Python Web表單提交

通常，與網(wǎng)頁的交互需要一些數(shù)據(jù)通過html頁面中的表單提交給服務(wù)器。這些網(wǎng)絡(luò)表單通常用于諸如注冊新帳戶或提供一些信息(例如姓名或卷號)以檢索檢查結(jié)果的過程。requests模塊使用帶有所需參數(shù)的POST方法優(yōu)雅地處理此問題。

示例

在下面的示例中，我們通過提供用戶名和密碼值來使用網(wǎng)站的注冊表單。提交值后，將打印響應(yīng)的結(jié)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()
  
 

執(zhí)行上面示例代碼，得到類似下面結(jié)果：

 
# Filename : example.py

Response to GET request:
