使用Python'请求'登录和上传文件 [英] Login and upload file using Python 'requests'

问题描述

我需要登录并上传文件。我面临的问题是，登录页面与上传页面不同。如果我必须手动完成，我将登录（ login.php ）到该站点，然后导航到上传页面（ uploader.php ）上传文件。这就是我写的：

I need to login and upload a file . The problem I am facing is, login page is different from uploading page. If I have to do it manually, I'll login (login.php) to the site and then navigate to the upload page (uploader.php) to upload the file. This what I have written:

import requests

url1='http://www.abc.com/login.php'
r = requests.post(url1, auth=('uname', 'pword'))
print r.status_code //msg:'200'

payload = {'upload':open('./tmp.txt')}
url2='http://www.abc.com/uploader.php'
r = requests.post(url2, data=payload)
print r.text //msg: "you must first login to upload the file"

我的代码显然没有按预期工作。登录部分工作正常但不上传部分。
请如何实现我的目标。

My code is obviously not working as expected. Login part is working correctly but not uploading part. Please how can I accomplish my goal.

更新：

为了更深入地了解我的问题，我给 login.php 和 uploader.php 文件详细信息：

To give more insight into my question, I am giving login.php and uploader.php file details:

login.php

<form method="POST" action="login.php" class="login">
<input type="text" name="username"></input>
<input type="password" name="password"></input>        
<input type="submit" value="Login"></input>

uploader.php

<form action='uploader.php' method='POST' id='form' class='upload' enctype="multipart/form-data" >
<input type='file' name='upload' id='file'></input>
<input type='button' value='Analyze' name='button' onclick='javascript: checkuploadform(false)'>

推荐答案

进行会话，然后使用该会话进行请求 -

Make a session and then use that session to do your requests -

sessionObj = requests.session()
sessionOj.get(...) # Do whatever ...

会话会保留您的cookie以备将来请求。

并使用post参数对于用户名，密码作为参数需要登录 login.php ，而不是auth用户名密码。

另外使用文件上传文件的参数。
所以最终代码是 -

A session persists your cookies for future requests.
And use post parameters for username,password as the parameters are required to login in login.php , not auth username password.
Also use files parameter to upload files. So the final code is -

import requests

sessionObj = requests.session()
url1='http://www.abc.com/login.php'
r = sessionObj.post(url1, params={'username':'usernamehere' , 'password':'password here'})
print r.status_code //msg:'200'


filehandle = open('./tmp.txt')
url2='http://www.abc.com/uploader.php'
r = sessionObj.post(url2, data={},files = {'upload':filehandle})
print r.text
