ruby-savon 与 mono-wcf 通信

Question

我是 mono wcf 的新手，我遇到了一些关于我的代码的问题。 最近，我使用 ruby​​-savon 从单声道的 wcf 主机获取数据。

这是我的 ruby 代码:

client = Savon::Client.new do 
wsdl.document="http://localhost:9000/MonoWcf/MonoSevice/wsdl" 
end
puts client.wsdl.soap_actions
response = client.request  :get_data

这就是:

这是 mono-wcf wsdl:

** `

<import location="http://localhost:9000/MonoWcf/MonoSevice/wsdl?wsdl=wsdl0" namespace="http://localhost:9000"/>
<types/>
<binding name="BasicHttpBinding_IMonoService" type="i0:IMonoService">
    <soap:binding transport="http://schemas.xmlsoap.org/soap/http"/>
    <operation name="GetData">
        <soap:operation soapAction="http://localhost:9000/IMonoService/GetData" style="document"/>
        <input>
            <soap:body use="literal"/>
        </input>
        <output>
            <soap:body use="literal"/>
        </output>
    </operation>
    <operation name="GetDataUsingDataContract">
        <soap:operation soapAction="http://localhost:9000/IMonoService/GetDataUsingDataContract" style="document"/>
        <input>
            <soap:body use="literal"/>
        </input>
        <output>
            <soap:body use="literal"/>
        </output>
    </operation>
</binding>
<service name="service">
    <port name="BasicHttpBinding_IMonoService" binding="tns:BasicHttpBinding_IMonoService">
        <soap:address location="http://localhost:9000/MonoWcf/MonoSevice/soap"/>
    </port>
</service>

` **但是当我在 Windows(7) 中托管 wcf 时，它确实获取了数据。

我的操作系统是:ubuntu 12单声道版本:

Mono JIT compiler version 2.10.8.1 (Debian 2.10.8.1-1ubuntu2.2)

非常感谢您的帮助!

这是我刚刚在 mono/master commit ea2f2cd 中修复的 Mono WCF 代码中的错误.

Ruby-savon 发送Content-Type: text/xml;charset=UTF-8，但服务器期望Content-Type: text/xml;字符集=utf-8。这是不正确的，检查应该不区分大小写并忽略空格。

您需要从 github 编译最新的单声道，或者作为临时解决方法，以某种方式让 ruby​​-savon 发送 Content-Type: text/xml; charset=utf-8.

临时解决方法

编辑 lib/savon/request.rb(在我的 Mac 上位于 /Library/Ruby/Gems/1.8/gems/savon-2.0.2)，在顶部，有

CONTENT_TYPE = {
  1 => "text/xml;charset=%s",
  2 => "application/soap+xml;charset=%s"
}

把它改成

CONTENT_TYPE = {
  1 => "text/xml; charset=%s",
  2 => "application/soap+xml; charset=%s"
}

然后设置编码为“utf-8”，例如:

require 'savon'

client = Savon.client(:wsdl => "http://localhost:9999/MyService?wsdl", :encoding => "utf-8")
puts client.operations
response = client.call(:hello)

在我的 Mac 上用 Ruby 1.8.7 测试过。
