Question

我的问题是 - 法拉第无法连接到网址。当我在浏览器http://localhost:3001/api/plans中打开它时，我得到了回应但是当我尝试从rails连接时，我得到响应状态405和空响应主体

  url = 'http://localhost:3001/api/plans'
  conn = Faraday.new(:url => url) do |faraday|
    faraday.request  :url_encoded             # form-encode POST params
    faraday.response :logger                  # log requests to STDOUT
    faraday.adapter  Faraday.default_adapter  # make requests with Net::HTTP
  end
  resp = conn.post do |req|
    req.headers['Content-Type'] = 'application/json'
    req.body = data.to_json
  end
  logger.info '**********************************'
  logger.debug "* Login params: #{data.inspect}"
  logger.debug "* Url: #{url} "
  logger.debug "* Response: #{resp.inspect} "
  logger.debug "* Response body: #{resp.body.inspect} "
  logger.info '**********************************'

记录器的输出是：

**********************************
* Login params: {:username=>"14122460670", :password=>"******", :remember_me=>"on"}
* Url: http://localhost:3001/api/plans 
* Response: #<Faraday::Response:0x007f9f5c467528 @env={:method=>:post, :body=>"", :url=>#<URI::HTTP:0x007f9f480da450 URL:http://localhost:3001/v1/sessions>, :request_headers=>{"User-Agent"=>"Faraday v0.8.7", "Content-Type"=>"application/json"}, :parallel_manager=>nil, :request=>{:proxy=>nil}, :ssl=>{}, :status=>405, :response_headers=>{"allow"=>"OPTIONS, GET, HEAD", "content-type"=>"text/plain", "connection"=>"close", "server"=>"thin 1.5.1 codename Straight Razor"}, :response=>#<Faraday::Response:0x007f9f5c467528 ...>}, @on_complete_callbacks=[]> 
* Response body: "" 
**********************************

为什么我无法使用法拉第获得回复，我怎么能得到它？

错误代码405表示不支持您正在使用的http方法。所以我认为问题可能是在浏览器中您使用GET方法访问此站点，而在法拉第中它是POST。

配置法拉第发送GET请求。

resp = conn.get do |req|
...

法拉第没有连接到网址
