Question

我正在尝试从BingAds网址下载.zip文件，并且正在努力绕过此错误：

Connection reset by peer - SSL_connect

我目前正在通过另一个应用程序在生产中运行此代码，但我正在使用nitrous.io在chromebook上运行新应用程序并运行默认的rails安装（亚硝基盒）。

目前在其他应用中使用的代码：

class BingApi
  def self.get_data(request_params={})
    require 'zip'

    #Acquire Bing report download URL
    report_url = BingApi.acquire_report_url(report_request_id, request_params)

    zip_file = open(report_url)

    unzippedxml = Zip::File.open(zip_file)                      # open zip
    entry = unzippedxml.entries.reject(&:directory?).first      # take first non-directory
    entry.get_input_stream{|is| is.read }          # read file contents
  end

report_url看起来像：https://download.api.bingads.microsoft.com/ReportDownload/Download.aspx?q=cWmkJ72lVlzGEG%2fouLL8Xes2j6I5qVhLrnTqNIrW ....

访问时，会提示下载.zip文件，我解压缩然后再解析。

然而，使用nitrous box的chromebook上的相同代码给我Connection reset by peer - SSL_connect错误

我一直在尝试各种不同的解决方案：

zip_file = open(report_url, :ssl_verify_mode => OpenSSL::SSL::VERIFY_NONE)

OR

zip_file = Faraday.get(report_url, :ssl => false)

最后我通过使用：

来绕过它

uri = URI.parse(report_url)
https = Net::HTTP.new(uri.host, uri.port)
https.open_timeout = 5
https.use_ssl = true
https.ssl_version = 'SSLv3'
request = Net::HTTP::Get.new(uri.request_uri)
zip_file = https.request(request)

但我无法将zip_file传递给unzippedxml = Zip::File.open(zip_file)，或者我收到no implicit conversion of Net::HTTPOK into String TypeError。

我在这里错过了一些简单的东西吗？我应该使用zip_file.class => Net::HTTPOK对象做些不同的事情吗？

我尝试调用zip_file.body但是如果您在解压缩之前尝试在编辑器中打开压缩文件，那么返回的内容就像您所看到的那样。

服务器坏了。

它仅支持显式TLS1.0和SSL3.0握手，不支持常用和最兼容的SSLv23握手。即使使用明确的TLS1.0握手，如果包含错误或过多的密码，它也会失败。 analyze.pl的相关输出：

* version SSLv23, no verification, ciphers= -> FAIL! SSL wants a read first
* version SSLv23, no verification, ciphers=HIGH:ALL -> FAIL! SSL wants a read first
* version TLSv1_2, no verification, ciphers= -> FAIL! SSL wants a read first
* version TLSv1_2, no verification, ciphers=HIGH:ALL -> FAIL! SSL wants a read first
* version TLSv1_1, no verification, ciphers= -> FAIL! SSL connect attempt failed error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number
* version TLSv1_1, no verification, ciphers=HIGH:ALL -> FAIL! SSL wants a read first
* version TLSv1 no verification, ciphers= -> TLSv1,AES256-SHA
* version TLSv1, no verification, ciphers=HIGH:ALL -> FAIL! SSL wants a read first
* version SSLv3 no verification, ciphers= -> SSLv3,AES256-SHA
* version SSLv3 no verification, ciphers=HIGH:ALL -> SSLv3,AES256-SHA
* supported SSL versions with handshake used and preferred cipher(s):
  * handshake protocols ciphers
  * SSLv23    FAILED: SSL wants a read first 
  * TLSv1_2   FAILED: SSL wants a read first 
  * TLSv1_1   FAILED: SSL connect attempt failed error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number SSL wants a read first 
  * TLSv1     TLSv1     AES256-SHA
  * SSLv3     SSLv3     AES256-SHA

在这里可以看到SSLv23，TLSv1_2和TLSv1_1握手不起作用，并且TLSv1握手确实有效，但如果密码为HIGH则不行：所有（可能包含太多密码或可能包含意外密码）。然后SSLv3握手可以稳定工作。

浏览器通过尝试多次同时缓慢降级握手中使用的SSL / TLS协议版本来解决此类行为。但除了浏览器之外，其他任何人都没有这样做。因此，除非专门配置为对此服务器使用TLS1.0或SSL3.0握手，否则任何其他应用程序通常都会失败。

但是我无法将zip_file传递给unzippedxml = Zip :: File.open（zip_file），或者我没有将Net :: HTTPOK隐式转换为String TypeError。

至少您提供的网址只返回404未找到。请检查您是否确实获得了ZIP文件。我不知道这个服务器，但通常这些下载链接是动态创建的，并且只有在你之前访问过其他网站并在那里获得cookie或类似的东西将URL绑定到浏览器会话时才有效。 / p>
