What MongoDB user role can make POST calls? - node.js

Question

I just have created a MongoDB instance on Ubuntu 14.04, with authentication by username:password.
The user I've created is like this:
{
"_id" : "myDatabase.myUser",
"user" : "myUser",
"db" : "myDatabase",
"roles" : [ { "role" : "readWrite", "db" : "myDatabase" } ]
}
And the URI String that I use on my REST API written in Node.js (with Express and Mongoose) is like:
mongodb://myUser:password#localhost:27017/myDatabase
The Connection is OK and the GET methods works fine, but when I use a POST method, like a signup by email/password, the response is:
Status Code:405 Not Allowed
Any idea? Thanks in advance!
FYI: I'm using Nginx as reverse proxy and Web Server for the Frontend (AngularJS app), and the config is:
server {
listen 80;
server_name example.com;
access_log /var/log/nginx/nginx.access.log;
error_log /var/log/nginx/nginx.error.log;
location / {
expires -1;
add_header Pragma "no-cache";
add_header Cache-Control "no-store, no-cache, must-revalidate, post-check=0, pre-check=0";
root /usr/share/www;
try_files $uri $uri/ /index.html =404;
}
location /api/v1 {
proxy_set_header "Access-Control-Allow-Origin";
proxy_set_header "Access-Control-Allow-Methods" "GET, POST, OPTIONS, PUT, DELETE";
proxy_set_header "Access-Control-Allow-Headers" "X-Requested-With,Accept,Content-Type, Origin";
proxy_pass http://127.0.0.1:3000/api/v1;
proxy_buffering on;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header origin "http://example.com";
}
}

Answer 1

I think that it isn't a mongodb restriction. Mongo can't know if the request is POST or GET. Have you verified if the request arrives at nodejs server? I think that nginx is who returns the 405 status code.
It's possible that the failure is due to try to return a static page as response to the POST request. Try adding into nginx.conf file:
# To dispatch static pages on POST request
error_page 405 = 200 $uri;

Answer 2

I have added the following and nginx at least works!:
proxy_redirect off;
The nginx config for default now is:
server {
listen 80;
server_name example.com;
access_log /var/log/nginx/nginx.access.log;
error_log /var/log/nginx/nginx.error.log;
location / {
expires -1;
add_header Pragma "no-cache";
add_header Cache-Control "no-store, no-cache, must-revalidate, post-check=0, pre-check=0";
root /usr/share/www;
try_files $uri $uri/ /index.html =404;
}
location /api/v1 {
proxy_set_header 'Access-Control-Allow-Origin' 'http:/example.com';
proxy_set_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS, PUT, DELETE';
proxy_set_header 'Access-Control-Allow-Headers' 'X-Requested-With,Accept,Content-Type, Origin';
proxy_pass http://127.0.0.1:3000/api/v1;
proxy_redirect off;
proxy_buffering on;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header origin "http://example.com";
}
}
I hope this be valid for somebody.
