User (Internet, Port 80)===upload===>Nginx (listens 80) saves files===redirect modified POST headers via port 8080===> Python Tornado (listens to 8080)====> return users information
1. Setting up Nginx
- I put the upload form (index.html) on /var/www/html/php, so I set this as the working directory (bad naming, but nevermind!)
==========
Index.html (from the Official example)
<html>
<head>
<title>Test upload</title>
</head>
<body>
<h2>Select files to upload</h2>
<form name="upload" method="POST" enctype="multipart/form-data" action="/upload">
<input type="file" name="file1"><br>
<input type="file" name="file2"><br>
<input type="file" name="file3"><br>
<input type="file" name="file4"><br>
<input type="file" name="file5"><br>
<input type="file" name="file6"><br>
<input type="submit" name="submit" value="Upload">
<input type="hidden" name="test" value="value">
</form>
</body>
</html>
Nginx.conf:
worker_processes 20;
error_log /var/log/nginx/error.log debug;
working_directory /var/www/html/php;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
server {
listen 80;
client_max_body_size 100m;
# Upload form should be submitted to this location
location / {
root /var/www/html/php;
index index.html index.htm;
}
location /upload {
# Pass altered request body to this location
upload_pass @test;
# Store files to this directory
# The directory is hashed, subdirectories 0 1 2 3 4 5 6 7 8 9 should exist << You must manually create these subdir before you upload, because Nginx upload does not support creating new directories
upload_store /tmp 1;
# Allow uploaded files to be read only by user
upload_store_access user:r;
# Set specified fields in request body
upload_set_form_field "${upload_field_name}_name" $upload_file_name;
upload_set_form_field "${upload_field_name}_content_type" $upload_content_type;
upload_set_form_field "${upload_field_name}_path" $upload_tmp_path;
# Inform backend about hash and size of a file
upload_aggregate_form_field "${upload_field_name}_md5" $upload_file_md5;
upload_aggregate_form_field "${upload_field_name}_size" $upload_file_size;
upload_pass_form_field "^submit$|^description$";
}
# Pass altered request body to a backend of 8080
location @test {
proxy_pass http://localhost:8080;
}
}
}
Tornado (rx.py)
import tornado.httpserver, tornado.web, tornado.ioloop, os.path
class requestHandler(tornado.web.RequestHandler):
print "Python receiver running"
def get (self):
print "Someone accessed through Get"
def post(self):
print self.request.arguments
#defines application of Tornado
#Pass any requests (post/get) to this handler
application=tornado.web.Application([
(r'/upload',requestHandler),
],)
#start the tornado, listens to 8080
if __name__=='__main__':
application.listen(8080)
tornado.ioloop.IOLoop.instance().start()
====================
1) Type: python rx.py
2) Goto http://localhost:8080/upload, get back to check if terminal shows "Someone accessed through Get" -->to show python working properly
3) Type: sudo nginx
4) Goto http://localhost/ --->should show an upload form
5) select file, upload ---->should show a blank page
6) go back to terminal, python interpreter should show something like this:
{u'file1_content_type': ['image/jpeg'], u'file1_md5': ['7fb958cd71e98537dd8e751d16f04ab9'], u'submit': ['Upload'], u'file1_name': ['1 copy.jpg'], u'file1_path': ['/tmp/9/0040448919'], u'file1_size': ['209926']}
1 copy.jpg is my uploaded file name. The key "file1_name" is the name of your upload form + suffix (_name) added by Nginx.
PS. Oh the file permission stuff may cause troubles. Pls change to 777 by chmod for testing purposes (remember to set to a safe value before into production!!!)
==End==
