Ruby on rails 将HTTP代理与Savon一起使用

我需要从Heroku访问带有IP白名单的服务，这就需要HTTP代理

我配置了Proximo插件，并且有一个近似于

http://proxy:secret-key@proxy-0-0-0-0.proximo.io

在Savon中，我尝试过如下配置代理：

client = Savon.client(wsdl: my_wsdl, proxy: "http://proxy:secret-key@proxy-0-0-0-0.proximo.io")

但当我提出请求时：

客户端操作

我得到一个代理错误：

但是，没有代理选项，一切都正常。

我认为这应该可以

client = Savon.client(wsdl: my_wsdl, proxy: "http://proxy-0-0-0-0.proximo.io", basic_auth: ["proxy-user", "proxy-secret"])

---

我想我找到了解决办法。 不便之处在于手动获取WSDL并将其保存到本地文件中。 例如

您必须将以下内容添加到客户端定义中

...
secret = Base64.strict_encode64("#{user}:#{password}")
client = Savon.client(
    wsdl: 'globalweather.wsdl',
    proxy: "http://my-proxy.example.com:8080",
    headers: { "Proxy-Authorization" => "Basic #{secret}" },
    ...
)

基本上就是这样。 通过直接指定

名称空间

和

端点

，也可以完全不使用WSDL

Savon使用芥末处理WSDL。它还从服务器获取文档。Wasabi不使用Savon客户机定义中的参数。要改变这一点，就必须扩大芥末宝石

可以在此处找到运行脚本：。

我认为用户：password@url语法只能在浏览器中使用。您可以尝试基本身份验证。据我所知，Savon文档没有指定如何进一步配置代理（在版本2中）@SteffenRollerI认为，因为代理连接是底层http模块的一个功能，可能有所不同。使用来源，卢克！正如我们所说的源代码：）httpclient知道代理授权：。您可能需要在代码中签入应用它的位置。basic_auth。不管怎样，我都试过了。嘿，史蒂芬，我来看看！我以前尝试过在头中设置代理授权，但没有单独下载WSDL。哈-我赢得了我的第一个赏金-呼-呼：-）

...
secret = Base64.strict_encode64("#{user}:#{password}")
client = Savon.client(
    wsdl: 'globalweather.wsdl',
    proxy: "http://my-proxy.example.com:8080",
    headers: { "Proxy-Authorization" => "Basic #{secret}" },
    ...
)
