HTTP POST（未知协议）上的SSL错误

Question

尝试通过SSL连接到Imgur API会给我一个错误。下面的代码和错误：

API_URI = URI.parse('https://api.imgur.com') 
    API_PUBLIC_KEY = 'Client-ID --' 

    ENDPOINTS = { 
    :image => '/3/image', 
    :gallery => '/3/gallery' 
    } 

    # Public: Upload an image 
    # 
    # args - The image path for the image to upload 
    # 
    def upload(image_path) 
    http = Net::HTTP.new(API_URI.host) 
    http.use_ssl = true 
    http.verify_mode = OpenSSL::SSL::VERIFY_NONE 

    params = {'image' => File.open(image_path)} 
    request = Net::HTTP::Post.new(API_URI.request_uri) 
    request.set_form_data(params) 
    request.add_field('Authorization', API_PUBLIC_KEY) 

    response = http.request(request) 
    puts response.body 
    end 

和错误：

`connect': SSL_connect returned=1 errno=0 state=SSLv2/v3 read server hello A: unknown protocol (OpenSSL::SSL::SSLError) 

我知道VERIFY_NODE是不好的做法，但我只是想测试一下现在的连接。

Ruby版本：1.9.2

Answer 1

创建HTTP客户端时指定端口修复了此问题。

http = Net::HTTP.new(API_URI.host, API_URI.port) 

或

http = Net::HTTP.new(API_URI.host, 443) 

Answer 2

对我来说，那是因为我已经开始将服务器作为HTTP（TCP：//）服务器，而不是HTTPS（SSL ：//）。即代替

bundle exec puma config.ru -b 'tcp://0.0.0.0:3456?key=/path/to/key.key&cert=/path/to/cert.crt' 

：

bundle exec puma config.ru -b 'ssl://0.0.0.0:3456?key=/path/to/key.key&cert=/path/to/cert.crt'
