Rails 之微信开发 : OpenSSL::SSL::SSLError: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed

 

微信公众平台，使用Ruby On Rails + Win7

在取得OpenID时，如果简单的使用http.get方法，会出现如下

SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed

解决方案:

    def get_open_id code
    url="https://api.weixin.qq.com/sns/oauth2/access_token?appid=xxx&secret=xxx&code=#{code}&grant_type=authorization_code"
   
    uri = URI.parse(url)
    http = Net::HTTP.new(uri.host, uri.port)
    http.use_ssl = true
    http.verify_mode = OpenSSL::SSL::VERIFY_NONE
    request = Net::HTTP::Post.new("/sns/oauth2/access_token?appid=xx&secret=xxx=#{code}&grant_type=authorization_code")
    request.add_field('Content-Type', 'application/json')
    #request.body = post_data.to_json
    response = http.request(request)
    json = JSON.parse(response.body)
    return json
  end

 二, 在生成二维码的时候，取得ticket时，如果简单的使用post_form方法，会出现如下

{"errcode":40052,"errmsg":"invalid action name"}

原因大致就是微信服务器收到的JSON格式不合法，不知道post_form提交的最终数据是怎么样的。

变通的方法是自己写post方法，稍微麻烦一些

uri = URI.parse("https://api.weixin.qq.com/cgi-bin/qrcode/create?access_token=#{access_token}")
post_data = {"expire_seconds" => 1800, "action_name" => "QR_SCENE", "action_info" => {"scene" => {"scene_id" => 123}}}

http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
request = Net::HTTP::Post.new("/cgi-bin/qrcode/create?access_token=#{access_token}")
request.add_field(‘Content-Type‘, ‘application/json‘)
request.body = post_data.to_json
response = http.request(request)
json = JSON.parse(response.body)
