Ruby學習筆記系列（一）

1, 用Net::HTTP.get

uri = URI('http://xxxxxxx.com/api/user/1.0/json/get_info?&user_id=3')
Net::HTTP.get(uri)

2, 用Net::HTTP.get 時加一些參數

uri = URI('http://xxxxxx.com/api/user/1.0/json/get_info')
params = { :user_id => 3}
uri.query = URI.encode_www_form(params)
res = Net::HTTP.get_response(uri)
puts res.body if res.is_a?(Net::HTTPSuccess)

3, Net::HTTP.post_form

uri = URI('http://xxxxx.com/api/user/1.0/json/login')
res = Net::HTTP.post_form(uri, 'client_id' => '159d8a2f931514c107280', 'identity' => 'xxxxx002','password' => 'xxxxxx')
puts res.body

4, res.methods里面有些很有用的方法

uri = URI('http://drhel31.sh.magima.com/api/user/1.0/json/get_info?&user_id=3')
res = Net::HTTP.get_response(uri)
# Headers
res.header          # => "#<Net::HTTPOK 200 OK readbody=true>"
res.read_header     # => "#<Net::HTTPOK 200 OK readbody=true>"
# Status 這個很有用，做接口調用成功與否的判斷可用。
puts res.code       # => '200'
puts res.message    # => 'OK'
puts res.class.name # => 'HTTPOK'
res.code_type       # =>  Net::HTTPOK
res.inspect         # =>  "#<Net::HTTPOK 200 OK readbody=true>"
# Body
puts res.body if res.msg =＝ "OK"

5, 判斷文件是否存在

File.exist? '/home/test/features/support/modul_login.rb'
