  • REST Client – simple DSL for accessing HTTP and REST resources

    https://github.com/rest-client/rest-client
    https://github.com/jnunemaker/httparty
    http://ruby-doc.org/stdlib-2.1.2/libdoc/net/http/rdoc/Net/HTTP.html
    https://www.imququ.com/post/four-ways-to-post-data-in-http.html
    工作中常用到获取一个xml或者json格式的数据进行解析,获取我们希望拿到的有效数据,这时候用的是http的get请求,
    当我们提交表单和上传文件的时候,用的是http的post请求,post请求的contentType分两种,
    提交普通的表单的时候,Content-Type是"application/x-www-form-urlencoded",
    上传文件的时候,Content-Type是"multipart/form-data"
    这个可以通过浏览器的调试工具查看
    点击F12打开页面调试工具,然后选择"Network"->"Headers"->"Request Headers"->"Content-Type"

    接下来我们分别看一下应用的场景

    (一)REST Client获取xml/json数据

    (1)xml
    response = RestClient.get(url)
    url_hash = Hash.from_xml(response.body)

    (2)json

    response = RestClient.get(url_list[index])
    url_hash = JSON.parse(response.body)['headline_videos']

    (二)httpparty获取json数据
    response = HTTParty.get('https://api.stackexchange.com/2.2/questions?site=stackoverflow')


    ==============================


    RestClient最大的优势在于在post请求的时候能够上传一个文件,
     module ClassMethods
        def upload_image(file_path)
          timestamp = Time.now.to_i
    
          response = RestClient.post Settings.upload.image.url, {
            uid: Settings.upload.image.uid,
            appkey: Settings.upload.image.appkey,
            timestamp: timestamp,
            sign: sign(timestamp),
            filename: "ott_cms_#{timestamp}",
            duplmd5: Settings.upload.image.duplmd5,
            file: File.new(file_path)
          }
    
          case response.code
          when 200
            parse_upload_response response
          else
            { errors: ["图片上传服务暂时不可用"] }
          end
        end
