<p>Is it possible to make a POST request from Ruby with open-uri?</p>

Unfortunately
```
open-uri
```
only supports the
```
GET
```
verb.
You can either drop down a level and use
```
net/http
```
, or use
```
rest-open-uri
```
, which was designed to support
```
POST
```
and other verbs. You can do
```
gem install rest-open-uri
```
to install it.
