A simple wrapper around standard Ruby Net::HTTP library.
If you need something more fully-featured you should use absolutely awesome [HTTP](https://github.com/httprb/http) gem. ([Why?](https://twin.github.io/httprb-is-great/))
---
## Installation
Add this line to your Gemfile:
```ruby
gem 'http_wrapper', '~> 4.0'
```
And then execute:
$ bundle
Or install it manually:
$ gem install http_wrapper
And require it in you code:
```ruby
require 'http_wrapper'
```
## Usage
Create wrapper object:
```ruby
http = HTTPWrapper.new
```
### Access unprotected resource located at **some_url**:
```ruby
response = http.get some_url
# response is always an instance of Net::HTTPResponse
```
Resource is redirecting? No problem! `http_wrapper` follows up to 10 sequential redirects by default.
But you can specify your own limits.
```ruby
http.max_redirects = 5
response = http.get some_url
```
Url doesn't have scheme? `http_wrapper` prefixes url with `http://` if scheme is missing.
```ruby
http.get 'example.com' # will correctly request 'http://example.com'
```
### Access resource protected by form-based authentication:
1. Post your credentials and get authentication cookie
```ruby
# 'username' and 'password' fields are examples, it's just query parameters
# credentials as body params
cookie = http.post_and_get_cookie some_url, body: { username: 'iamjohn', password: '$uperS1kret' }
# - or - credentials as GET query params
cookie = http.post_and_get_cookie some_url, query: { username: 'iamjohn', password: '$uperS1kret' }
```
2. Get protected resource with provided cookie
```ruby
response = http.get some_url, cookie: cookie
```
### Access resource protected by basic access authentication:
```ruby
response = http.get 'http://example.com', auth: { login: 'iamjohn', password: 'iamnotjohn' }
# => http://iamjohn:iamnotjohn@example.com
```
### Access resource mimicing AJAX
Add special header or use special method:
```ruby
response = http.get_ajax some_url
# - or -
response = http.get some_url, headers: { x_requested_with: 'XMLHttpRequest' }
# - or -
response = http.get some_url, headers: { 'X-Requested-With' => 'XMLHttpRequest' }
```
### Access JSON resource
Same as before :)
```ruby
response = http.get_json some_url
# - or -
response = http.get some_url, content_type: 'application/json; charset=UTF-8'
# - or -
response = http.get some_url, headers: { content_type: 'application/json; charset=UTF-8' }
# - or -
response = http.get some_url, headers: { 'Content-Type' => 'application/json; charset=UTF-8' }
```
### Access JSON resource mimicing AJAX
Just use special method :) (which sets `X-Requested-With` and `Content-Type` headers for you)
```ruby
response = http.get_ajax_json some_url, some_params
```
Difficult to remember what goes after what: `get_ajax_json` or `get_json_ajax`?
`http_wrapper` got you covered. They both work, use whatever variant you like better.
```ruby
# the same as above
response = http.get_json_ajax some_url, some_params
```
### Provide additional query parameters
Don't worry about escaping, `http_wrapper` got you covered here either.
```ruby
response = http.get 'http://www.google.com', query: { message: 'Hi! M&Ms!', user: 'iamjohn' }
# => http://www.google.com/?message=Hi!%20M%26Ms!&user=iamjohn
```
Don't worry about parameters that already in URL, they'll be merged.
```ruby
response = http.get 'http://www.google.com/?q=test', query: { user: 'iamjohn' }
# => http://www.google.com/?q=test&user=iamjohn
```
### Files upload
You can easily upload any number of files with `multipart/form-data` content type.
```ruby
http = HTTPWrapper.new
params = {
multipart: [
# ['file input field name', 'File instance or string', { filename: 'itsfile.jpg', content_type: '...' }]
['user_photo', File.read('user_photo.jpg'), { filename: 'photo.jpg' }],
# last element is optional
['user_pic', File.open('user_pic.jpg')],
# you can also specify other parameters
['user_name', 'john griffin']
],
# or you can specify other parameters in body section
# it will be merged with multipart data
body: {
user_age: 25
}
}
response = http.post some_url, params
```
### Set timeout
By default timeout is set to 10 seconds.
```ruby
http.timeout = 5 # in seconds
# - or - on instantiation
http = HTTPWrapper.new timeout: 5
```
### Set logger
If you need to debug your requests, it's as simple as to say to `http_wrapper` where to output debug information.
```ruby
logger = Logger.new '/path/to/log_file'
http.logger = logger
# - or -
http = HTTPWrapper.new logger: $stdout
# - to switch logger off -
http.logger = nil
```
### Work over SSL
`http_wrapper` works with SSL out of the box and by default verifying domain SSL certificate.
But you can easily turn verification off if needed.
```ruby
http.verify_cert = false
# - or - on instantiation
http = HTTPWrapper.new verify_cert: false
```
### POST, PUT and DELETE requests
On each `get` method there are `post`, `put` and `delete` methods. Examples:
```ruby
http.post some_url, body: { user: 'iamjohn', password: 'secret' }
# - or -
http.put some_url, body: { user: 'iamjohn', password: 'secret' }
# - or -
http.delete some_url, query: { user: 'iamjohn' }
```
Default content type header for these requests is `application/x-www-form-urlencoded; charset=UTF-8`.
So for `get_ajax` there are `post_ajax`, `put_ajax` and `delete_ajax`.
For `get_soap` there are `post_soap`, `put_soap` and `delete_soap`.
For `get_json` there are `post_json`, `put_json` and `delete_json`.
And for `get_ajax_json`, there are `post_ajax_json`, `put_ajax_json` and `delete_ajax_json`.
### Change User Agent
```ruby
http = HTTWrapper.new user_agent: 'custom user agent'
# - or -
http.user_agent = 'custom user agent'
http.get sample_url
# - or -
http.get sample_url, user_agent: 'custom user agent'
# - or -
http.get sample_url, headers: { user_agent: 'custom user agent' }
# the last one always replaces other definitions
```
### Perform own custom Net::HTTP requests
```ruby
uri = URI 'http://example.com'
request = Net::HTTP::Head.new uri
http.execute request, uri
```
### Full params hash example
```ruby
{
# Request Headers
headers: {
'Content-Type' => 'text/html',
'X-Requested-With' => 'XMLHttpRequest',
'User-Agent' => 'Chrome v123',
# - or - use symbols
content_type: 'text/xml',
x_requested_with: 'XMLHttpRequest',
user_agent: 'Chrome v123'
},
# Query Parameters
query: {
user: 'iamjohn',
'user-stuff' => '123abc'
},
# Cookie
cookie: 'all cookies in one string',
# Basic authentication credentials
auth: {
login: 'iamjohn',
password: 'secret'
},
# Request body
body: 'as a string',
# - or -
body: {
as: 'a hash'
},
# Shortcut for User-Agent header (headers hash takes precedence)
user_agent: 'UserAgent v1.2.3',
# Shortcut for Content-Type header (headers hash takes precedence)
content_type: 'text/xml',
# multipart/form-data for file uploads
# the format of array of arrays is important here!
multipart: [
# you can use File object
['file_input_name', File.open('somefile.ext')],
# - or - string and specify filename
['file_input_name', File.read('somefile.ext'), { filename: 'readme.txt' }],
# - or - full format
['file_input_name', 'some file content', { filename: 'readme.txt', content_type: 'text/text' }],
# - or - add other simple parameters
['user_name', 'john smith']
]
}
```
Don't worry if you mistype root parameters key. `http_wrapper` checks root parameters keys and instantiation options keys.
If any unknown options or parameters found, it raises the `UnknownKeyError` exception.
