# NiceHttp
[](https://rubygems.org/gems/nice_http)
[](https://github.com/MarioRuiz/nice_http)
[](https://coveralls.io/github/MarioRuiz/nice_http?branch=master)
NiceHttp the simplest library for accessing and testing HTTP and REST resources.
Manage different hosts on the fly. Easily get the value you want from the JSON strings. Use hashes on your requests. Get automatically statistics of your http communication and all the logs with the requests and responses.
Also you can use mock responses by using :mock_response key on the request hash and enable the use_mocks option on NiceHttp.
NiceHttp will take care of the redirections and the cookies, and for security tests you will be able to modify the cookies or disable and control the redirections by yourself.
NiceHttp is able to use hashes as requests data and uses the Request Hash structure: https://github.com/MarioRuiz/Request-Hash
**On the next link you have a full example using nice_http and RSpec to test REST APIs, Uber API and Reqres API: https://github.com/MarioRuiz/api-testing-example**
To be able to generate random requests take a look at the documentation for nice_hash gem: https://github.com/MarioRuiz/nice_hash
Example that creates 1000 good random and unique requests to register an user and test that the validation of the fields are correct by the user was able to be registered. Send 800 requests where just one field is wrong and verify the user was not able to be created: https://gist.github.com/MarioRuiz/824d7a462b62fd85f02c1a09455deefb

## Installation
Install it yourself as:
$ gem install nice_http
## A very simple first example
```ruby
require 'nice_http'
http = NiceHttp.new('https://reqres.in')
resp = http.get("/api/users?page=2")
pp resp.code
pp resp.data.json
resp = http.get("/api/users/2")
pp resp.data.json(:first_name, :last_name)
resp = http.post( {
path: "/api/users",
data: { name: "morpheus", job: "leader" }
} )
pp resp.data.json
```
## Create a connection
The simplest way is just by supplying the value as an argument:
```ruby
# as an url
http1 = NiceHttp.new("https://example.com")
# as parameters
http2 = NiceHttp.new( host: "reqres.in", port: 443, ssl: true )
# as a hash
http3 = NiceHttp.new my_reqres_server
```
You can specify all the defaults you will be using when creating connections by using the NiceHttp methods, in this example, http1 and http2 will be connecting to reqres.in with the default parameters and http3 to example.com:
```ruby
# default parameters
NiceHttp.host = 'reqres.in'
NiceHttp.ssl = true
NiceHttp.port = 443
NiceHttp.debug = false
NiceHttp.log = "./my_logs.log"
NiceHttp.headers = {"api-key": "the api key"}
NiceHttp.values_for = { region: 'europe', customerId: 334 }
http1 = NiceHttp.new()
http2 = NiceHttp.new()
http3 = NiceHttp.new("https://example.com")
```
If you prefer to supply a hash to change the default settings for NiceHttp:
```ruby
NiceHttp.defaults = {
host: 'reqres.in',
ssl: true,
port: 443,
timeout: 15, #seconds
debug: false,
log: "./my_logs.log",
headers: {"api-key": "the api key"}
}
```
To add a fixed path that would be added automatically to all your requests just before the specified request path, you can do it by adding it to `host`:
```ruby
http = NiceHttp.new('https://v2.namsor.com/NamSorAPIv2/')
resp = http.get('/api2/json/gender/Peter/Moon')
# The get request path will be: /NamSorAPIv2/api2/json/gender/Peter/Moon on server v2.namsor.com
resp = http.get('/api2/json/gender/Love/Sun?ret=true')
# The get request path will be: /NamSorAPIv2/api2/json/gender/Love/Sun on server v2.namsor.com
```
## Creating requests
You can use hash requests to simplify the management of your requests, for example creating a file specifying all the requests for your Customers API.
The keys you can use:
*path*: relative or absolute path, for example: "/api2/customers/update.do"
*headers*: specific headers for the request. It will include a hash with the values.
*data*: the data to be sent for example a JSON string. In case of supplying a Hash, Nice Http will assume that is a JSON and will convert it to a JSON string before sending the request and will add to the headers: 'Content-Type': 'application/json'
*mock_response*: In case of use_mocks=true then NiceHttp will return this response
Let's guess you have a file with this data for your requests on */requests/example.rb*:
```ruby
module Requests
module Example
# simple get request example
def self.list_of_users()
{
path: "/api/users?page=2"
}
end
# post request example using a request hash that will be converted automatically to a json string
def self.create_user_hash()
{
path: "/api/users",
data: {
name: "morpheus",
job: "leader"
}
}
end
# post request example using a JSON string
def self.create_user_raw()
{
path: "/api/users",
headers: {"Content-Type": "application/json"},
data: '{"name": "morpheus","job": "leader"}'
}
end
end
end
```
Then in your code you can require this request file and use it like this:
```ruby
resp = http.get Requests::Example.list_of_users
pp resp.code
resp = http.post Requests::Example.create_user_hash
pp resp.data.json
resp = http.post Requests::Example.create_user_raw
pp resp.data.json(:job)
```
In case you want to modify the request before sending it, for example just changing one field but the rest will be the same, you can supply a new key :values_for in the request hash that will contain a hash with the keys to be changed and NiceHttp will perform the necessary changes at any level:
```ruby
req = Requests::Example.create_user_hash
req.values_for = {job: "developer"}
resp = http.post req
pp resp.data.json
#response: {:name=>"morpheus", :job=>"developer", :id=>"192", :createdAt=>"2018-12-14T14:41:54.371Z"}
```
If the request hash contains a key :method with one of these possible values: :get, :head, :delete, :post or :patch, then it is possible to use the `send_request` method and pass just the request hash:
```ruby
req= {
path: "/api/users",
method: :post,
data: {
name: "morpheus",
job: "leader"
}
}
resp = @http.send_request req
```
You can always access to the last request as a Hash object by: `NiceHttp.request`
If you want to change the value of all headers using the value of the request on runtime, use `lambda`, `NiceHttp.requests` and `NiceHttp.request`:
```ruby
NiceHttp.requests = {
headers: {
Referer: lambda { "http://myserver.com" + NiceHttp.request.path }
}
}
```
You can use `NiceHttp.requests` to specify certain `headers`, `path` parameters or `data` or `values_for` that will apply on all requests sent.
```ruby
NiceHttp.requests = {
path: 'api-version=2022-12-09&testing=true',
data: {
properties: {
language: 'eng-us'
}
}
}
```
Lambdas can be used also on data and values_for to change the payloads in real-time. In case the lambda returns 'nil' the key won't be added to the request.
```ruby
NiceHttp.requests = {
data: {
zones: lambda { ENV['ZONES'] if NiceHttp.request[:method] == 'PUT' and NiceHttp.request[:path].match?(/^\/api\/users\/\d+/)}
},
values_for: {
region: lambda { 'Europe' if NiceHttp.request[:name] == 'Users.add' }
}
}
```
## Responses
The response will include at least the keys:
*code*: the http code response, for example: 200
*message*: the http message response, for example: "OK"
*data*: the data response structure. In case of json we can get it as a hash by using: `resp.data.json`. Also you can filter the json structure and get what you want: `resp.data.json(:loginname, :address)`
Also interesting keys would be: *time_elapsed_total*, *time_elapsed* and many more available
### Async responses
In case a 202 response and set the async settings, it will wait until the operation finishes and will return the result:
```ruby
NiceHttp.async_wait_seconds = 10
NiceHttp.async_header = 'location'
NiceHttp.async_completed = 'percComplete'
NiceHttp.async_resource = 'resourceName'
NiceHttp.async_status = 'status'
http = NiceHttp.new('https://exampleSinatra.tcblues.repl.co')
response = http.get '/async'
pp response # =>
{ :code=>"202",
:message=>"Accepted",
:location=>"https://exampleSinatra.tcblues.repl.co/operation/667",
:data=>"{\"result\":\"this is an async operation id: 667\"}",
:async=>
{ :seconds=>4,
:data=>
"{'percComplete':100,'resourceName':'/resource/766','status':'Done','operationId':'667'}",
:status=>"Done",
:resource=>{:data=>"{'resourceId':'766','lolo':'lala'}"}
}
# plus other keys
}
p response.code # 202
p response.location # "https://exampleSinatra.tcblues.repl.co/operation/667"
p response.data.json # {:result=>"this is an async operation id: 667"}
p response.async.data.json # {:percComplete=>100, :resourceName=>"/resource/766", :status=>"Done",:operationId=>667}
p response.async.status # Done
p response.async.seconds # 4
p response.async.resource.data.json # {:resourceId=>"766", :lolo=>"lala"}
```
## Special settings
*debug*: (true or false) it will set the connecition on debug mode so you will be able to see the whole communication with the server in detail
*log*: (:no, :screen, :file, :file_run, :fix_file, "filename") it will log the basic communication for inspect. In case you want to add extra info to your logs you can do it for example adding to your code: http.logger.info "example extra log"
*headers*: Hash containing the headers for the communication
*cookies*: Hash containing the cookies for the communication
*proxy_port, proxy_host*: in case you want to use a proxy for the connection
*use_mocks*: (true or false) in case of true if the request hash contains a mock_response key it will be returning that response instead of trying to send the request.
*auto_redirect*: (true or false) in case of true it will take care of the auto redirections.
*timeout*: Integer that will set a time out for the time waiting to connect to a host or waiting for a response.
## Authentication requests
All we need to do is to add to our request the correct authentication tokens, seeds, headers.
### Basic Authentication
For example for Basic Authentication we need to add to the authorization header a seed generated with the user and password we want ot authenticate
```ruby
@http = NiceHttp.new("https://jigsaw.w3.org/")
@http.headers.authorization = NiceHttpUtils.basic_authentication(user: "guest", password: "guest")
# headers will be in this example: {:authorization=>"Basic Z3Vlc3Q6Z3Vlc3Q=\n"}
resp = @http.get("/HTTP/Basic/")
```
In case you want to use strict base64 use the option `strict: true`
Remember for other kind of authentication systems NiceHttp take care of the redirections and cookies that are requested to be set. In case you need to add a header with a token you can add it by using your NiceHttp object and the key headers, for example:
```ruby
@http.headers.tokenuno = "xxx"
# headers => {tokenuno: "xxx"}
#another way:
@http.headers[:tokendos] = "yyy"
# headers => {tokenuno: "xxx", tokendos: "yyyy"}
```
In case you want or need to control the redirections by yourself instead of allowing NiceHttp to do it, then set ```@http.auto_redirect = false```
### OpenID
An example using OpenID authentication:
```ruby
server = "https://samples.auth0.com/"
path="/authorize?client_id=kbyuFDidLLm280LIwVFiazOqjO3ty8KH&response_type=code"
@http = NiceHttp.new(server)
resp = @http.get(path)
p "With autoredirection:"
p "Cookies: "
p @http.cookies
p "Code: #{resp.code} #{resp.message} "
p "*"*40
@http2 = NiceHttp.new(server)
@http2.auto_redirect = false
resp = @http2.get(path)
p "Without autoredirection:"
p "Cookies: "
p @http2.cookies
p "Code: #{resp.code} #{resp.message} "
```
The output:
```
"With autoredirection:"
"Cookies: "
{"/"=>{"auth0"=>"s%3A6vEEwmmIf-9YAG-NjvsOIyZAh-NS97jj.yFSXILdmCov6DRwXjEei3q3eHIrxZxHI4eg4%2BTpUaK4"},
"/usernamepassword/login"=>{"_csrf"=>"bboZ0koMScwXkISzWaAMTYdY"}}
"Code: 200 OK "
"****************************************"
"Without autoredirection:"
"Cookies: "
{"/"=>{"auth0"=>"s%3AcKndc44gllWyJv8FLztUIctuH4b__g0V.QEF3SOobK8%2FvX89iUKzGbfSP4Vt2bRtY2WH7ygBUkg4"}}
"Code: 302 Found "
```
### OAuth2
You can see on the next link how to get the OAuth2 token for Microsoft Azure and add it to your Http connection header.
https://gist.github.com/MarioRuiz/d3525185024737885c0c9afa6dc8b9e5
### JWT token
An example for Google using JWT
my_json_key_file.json:
```json
{
"type": "service_account",
"project_id": "example",
"private_key_id": "fjdslkafldkasfadsjflkjdsaklfjasdklfjlkdsjfl",
"private_key": "-----BEGIN PRIVATE KEY-----....==\n-----END PRIVATE KEY-----\n",
"client_email": "[email protected]",
"client_id": "46545646",
"auth_uri": "https://accounts.google.com/o/oauth2/auth",
"token_uri": "https://oauth2.googleapis.com/token",
"auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
"client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/example%40example.iam.gserviceaccount.com"
}
```
```ruby
require 'jwt'
require 'nice_hash'
def generate_jwt(audience, json_key_file)
json = File.open(json_key_file).read.json
now = Time.new
payload = {
iss: json.client_email,
sub: json.client_email,
aud: audience,
exp: (now + 3600).to_i,
iat: (now - 60).to_i,
kid: json.private_key_id
}
jwt_token = JWT.encode payload, OpenSSL::PKey::RSA.new(json.private_key), "RS256"
return jwt_token
end
NiceHttp.headers = {
Authorization: lambda { "Bearer " + generate_jwt('https:/myhost.com', './my_json_key_file.json') }
}
```
### lambda on headers
If you need a new token every time a new http connection is created you can use `lambda`
```ruby
NiceHttp.headers[:Authorization] = lambda {get_token()}
```
NiceHttp will call the get_token method you created every time a new connection is created.
## Http logs
You can set where the http logs will be stored by using the log attribute of the NiceHttp.
By default they will be stored in your root directory with the name nice_http.log.
```ruby
# you can specify the default for all connections
NiceHttp.log = :file_run
# also you can specify for a concrete connection
http = NiceHttp.new({host: 'www.example.com', log: './example.log'})
```
Other values you can supply:
* :fix_file, will log the communication on nice_http.log. (default).
* :no, won't generate any logs.
* :screen, will print the logs on the screen.
* :file, will be generated a log file with name: nice_http_YY-mm-dd-HHMMSS.log.
* :file_run, will generate a log file with the name where the object was created and extension .log, fex: myfile.rb.log
* String, the path and file name where the logs will be stored.
In case you want to hide the header values from the requests on the logs use the option `log_headers`. Possible values:
* :all, (default), will log all header values.
* :none, won't log any value of the headers.
* :partial, will log only the last 10 characters of the header values.
Example of logs:
```

```
If you want to get the last request sent or the last response as a message use `NiceHttp.last_request` or `NiceHttp.last_response`. If you want to access the last request as a Hash use `NiceHttp.request`
Also you can collect all data sent and received by setting `NiceHttp.capture = true` and all data will be stored on `NiceHttp.captured` as an Array of Strings (Request+Response).
### Multithreading
In case you want to use multithread and log in different files every thread, add an unique name for the thread then the logs will be stored accordingly
```ruby
require 'nice_http'
threads = []
40.times do |num|
threads << Thread.new do
Thread.current.name = num.to_s
http = NiceHttp.new("https://reqres.in")
request = {
path: '/api/users',
data: { name: 'morpheus', job: 'leader' },
}
http.post(request)
end
end
threads.each(&:join)
# log files: nice_http_0.log, nice_http_1.log... nice_http_39.log
```
## Http stats
If you want to get a summarize stats of your http communication you need to set `NiceHttp.create_stats = true`
Then whenever you want to access the stats: `NiceHttp.stats` and if you want to save it on a file: `NiceHttp.save_stats`
After the run is finished the stats will automatically be saved even if you didn't call `save_stats`. The stats files will use the name and path on `NiceHttp.log`.
If you are using RSpec and you want to generate the stats files after every test is finished, add to your spec_helper.rb file:
```ruby
RSpec.configure do |config|
config.after(:each) do
NiceHttp.save_stats
end
end
```
This is an example of the output:
```yaml

```
If you want to add specific stats for your processes you can use the method `NiceHttp.add_stats`
```ruby
# random customer name
customer_name = "10-20:L".gen
started = Time.now
@http.send_request Requests::Customer.add_customer(name: customer_name)
30.times do
resp = @http.get(Requests::Customer.get_customer(name: customer_name))
break if resp.code == 200
sleep 0.5
end
NiceHttp.add_stats(:customer, :create, started, Time.now)
```
To add the items for every specific stats to be accessed as an array you can add it as the last parameter of `add_stats`
```ruby
NiceHttp.add_stats(:customer, :create, started, Time.now, customer_name)
```
This will generate an items key that will contain an array of the values you added.
## Tips
### Download a file
* Direct download:
```ruby
resp = NiceHttp.new("https://github.com").get("/MarioRuiz/slack-smart-bot/blob/master/slack-smart-bot.png", save_data: './tmp/')
```
* Get the data and store it like you want:
```ruby
resp = NiceHttp.new("https://github.com").get("/MarioRuiz/slack-smart-bot/blob/master/slack-smart-bot.png")
File.open('./slack-smart-bot.png', 'wb') { |fp| fp.write(resp.data) }
```
### Send multipart content
Example posting a csv file:
```ruby
require 'net/http/post/multipart'
request = {
path: "/customer/profile/",
headers: {'Content-Type' => 'multipart/form-data'},
data: (Net::HTTP::Post::Multipart.new "/customer/profile/",
"file" => UploadIO.new("./path/to/my/file.csv", "text/csv"))
}
[email protected](request)
```
