ruby中的NET::HTTP方法不支持持久连接，如果您执行许多HTTP请求，则不推荐它们；这里暂时先列出几个固定用法(用来还是有点不舒服的)：
其中一，二不支持请求头设置(header取ruby默认值)，只能用于基本的请求；三，四可以设置请求头；
NET::HTTP不能处理重定向和404 ；不支持会话保持
一. 基本GET请求get_response
require ‘net/http‘# 基本GET请求require ‘net/http‘uri = URI(‘http://httpbin.org/get‘)response = Net::HTTP.get_response(uri)puts response.body# 带参数的GET请求require ‘net/http‘uri = URI(‘http://httpbin.org/get?name=zhaofan&age=23‘)response = Net::HTTP.get_response(uri)puts response.body# 如果我们想要在URL查询字符串传递数据，通常我们会通过httpbin.org/get?key=val方式传递# URI模块允许使用 encode_www_form 方法，将一个HASH来进行转化，例子如下：require ‘net/http‘uri = URI(‘http://httpbin.org/get?‘)data = {name:‘zhaofan‘, age:23}uri.query = URI.encode_www_form(data)response = Net::HTTP.get_response(uri)puts response.body二.基本post请求post_form(header默认为application/x-www-form-urlencoded)
require ‘net/http‘# 基本POST请求# 通过在发送post请求时添加一个params参数，这个params参数可以通过字典构造成;# 该方法底层和get_response一样都是调用了response方法uri = URI(‘http://httpbin.org/post‘)params = {name:‘zhaofan‘, age:23}res = Net::HTTP.post_form(uri, params)puts res.body三.get固定用法
require ‘net/http‘url = URI(‘http://httpbin.org/get?‘)# 设置请求参数params = {‘name‘:‘test‘}url.query = URI.encode_www_form(params)http = Net::HTTP.new(url.host, url.port)# 设置请求头header = {‘user-agent‘:‘Chrome/61.0.3163.100‘}response = http.get(url, header)puts response.body四.post固定用法
- application/json
require ‘net/http‘require ‘json‘#application/jsonurl = URI(‘http://httpbin.org/post‘)http = Net::HTTP.new(url.host, url.port)# 设置请求参数data = {‘code‘:1, ‘sex‘:‘男‘, ‘id‘:1900, ‘name‘: ‘test‘}.to_json# 设置请求头header = {‘content-type‘:‘application/json‘}response = http.post(url, data, header)puts response.body - application/x-www-form-urlencoded
require ‘net/http‘require ‘json‘#application/x-www-form-urlencodedurl = URI(‘http://httpbin.org/post‘)http = Net::HTTP.new(url.host, url.port)#encodeURI参数data = URI.encode_www_form({‘name‘:‘test‘})#设置请求头header = {‘content-type‘:‘application/x-www-form-urlencoded‘}response = http.post(url, data,header)puts response.body
五.response响应内容
require ‘net/http‘uri = URI(‘http://www.baidu.com‘)response = Net::HTTP.get_response(uri)puts "http版本：#{response.http_version}" #=> 1.1puts "响应代码： #{response.code}" #=> 200puts "响应信息：#{response.message}" #=> okputs "uri：#{response.uri}" #=> http://www.baidu.computs "解码信息：#{response.decode_content}" #=> trueputs response.body #=> 响应体response.header.each do |k,v| ?puts "#{k}:#{v}"end #=> 响应头六.发送https请求
require ‘net/https‘# 设置httpshttp.use_ssl = truehttp.verify_mode = OpenSSL::SSL::VERIFY_NONE
ruby net/http模块使用
