Question

我需要使用Heroku的IP白名单访问服务，因此需要HTTP代理。

我配置了Proximo插件，并且有一个类似于http://proxy:secret-key@proxy-0-0-0-0.proximo.io的代理网址

在Savon中，我尝试过像这样配置代理：

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

但是当我提出请求时：

client.operations

我收到了代理错误：

Wasabi::Resolver::HTTPError: Error: 407 for url http://mywsdl

        from bin/rails:4:in `require'
        from bin/rails:4:in `<main>'

但是没有代理选项，一切正常。

我想我找到了解决方案。不方便的是手动获取WSDL并将其保存到本地文件中。例如

curl http://www.webservicesx.net/globalweather.asmx?wsdl > globalweather.wsdl

您必须将以下内容添加到客户端定义

...
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namespace和endpoint，您也可以在没有WSDL的情况下完全工作。

Savon使用Wasabi来处理WSDL。它还从服务器获取文档。 Wasabi没有使用Savon客户定义中的参数。要改变它，就必须扩展芥末宝石。

使用与Savon
