问题
I have the url, where I need to send a video file. For this reason i wrote this code:
import requests
upload_url = 'https://cs506200.vk.me/upload_video_new.php?act=add_video&mid=21844505&oid=21844505&vid=171170813&fid=0&tag=93bb46ee&hash=e238f469a32fe7eee85a&swfupload=1&api=1'
file_ = {'file': ('video.mp4', open('video.mp4', 'rb'))}
r = requests.post(upload_url, files=file_)
print (r.text)
I get an error: {"error":"invalid file"}
But in this case:
<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
</head>
<body>
<form enctype="multipart/form-data" action="https://cs506200.vk.me/upload_video_new.php?act=add_video&mid=21844505&oid=21844505&vid=171170813&fid=0&tag=93bb46ee&hash=e238f469a32fe7eee85a&swfupload=1&api=1" method="POST" target="_blank">
<input type="file" name="video_file" />
<input type="submit" value="submit" name="submit" />
</form>
</body>
</html>
All working fine. What am I doing wrong?
回答1:
You are using the wrong field name:
file_ = {'file': ('video.mp4', open('video.mp4', 'rb'))}
That names the field file while your form uses video_file:
<input type="file" name="video_file" />
Using the right field name is important, correct your parameters:
file_ = {'video_file': ('video.mp4', open('video.mp4', 'rb'))}
