C# - 如何在Amadeus API上发送SOAP请求。

Question

我最近刚开始体验Amadeus API。

我在C#上开发Web服务并生成SOAP请求（包括头）。当我发送请求时，我收到了如下所示的错误。

这是我生成的请求。

        </reservationOrProfileIdentifier>

    </PNR_Retrieve>
  </soapenv:Body>
</soapenv:Envelope>

我认为我的请求是正确的，因为我的请求在SOAP用户界面上工作。而收到的响应是

         <faultactor>SI:Backend</faultactor>
      </soap:Fault>
   </soapenv:Body>
</soapenv:Envelope>

UPDATE: 我探索了额外的错误，如下

    <?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    <soap:Body>
        <soap:Fault>
            <faultcode>soap:Client</faultcode>
            <faultstring>12|Presentation|soap message header incorrect</faultstring>
            <faultactor>SI:muxDZ2</faultactor>
        </soap:Fault>
    </soap:Body>
</soap:Envelope>

它给了我soap消息头不正确的错误。但我的请求在SOAP用户界面上可以工作。

更新2: 通过修改SOAP Action解决了这个错误。正确的代码作为答案发布。

Answer 1

我解决了我的问题，我的HTTPWebRequest是不正确的。

下面是我的正确代码。webRequest.Headers.Add值应该和SOAP请求动作值一样。

        HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
        webRequest.Credentials = CredentialCache.DefaultNetworkCredentials;
        webRequest.Headers.Add("SOAPAction:\"http://webservices.amadeus.com/PNRRET_17_2_1A\"");
        webRequest.ContentType = "text/xml; charset=utf-8";
        webRequest.Accept = "text/xml";
        webRequest.Method = "POST";
        return webRequest;

SOAP请求.Headers.Add值应该和SOAP请求动作值一样。

        <add:Action xmlns:add=""http://www.w3.org/2005/08/addressing"">http://webservices.amadeus.com/PNRRET_17_2_1A</add:Action>
