【问题描述】:
我需要手动调用 WCF(通过 HttpWebRequest)。我可以通过添加 Web 引用并通过代理调用它来调用我的服务,因此我知道服务设置正确,并且证书、Web 配置等都是正确的。根据我找到的示例,我认为我做得正确,但仍然收到内部错误 500。
编辑:WebService 正在使用 wsHttpBinding。
控制台应用代码是:
HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://localhost:8733/Design_Time_Addresses/WcfServiceLibrary1/Service1");
string strRequest = Properties.Resources.TextFile1;
req.Method = "POST";
req.ContentType = "application/soap+xml; charset=utf-8";
req.ContentLength = strRequest.Length;
req.Credentials = new NetworkCredential("test", "test");
using (Stream stream = req.GetRequestStream())
{
stream.Write(UTF8Encoding.Default.GetBytes(strRequest), 0, strRequest.Length);
}
using (WebResponse res = req.GetResponse())
{
// nothing to do here
}
TextFile1 是 XML 请求...现在只是硬编码:
<s:Envelope xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope">
<s:Header>
<a:Action s:mustUnderstand="1">http://tempuri.org/IService1/GetData</a:Action>
<a:MessageID>urn:uuid:f3c2172e-eeb9-4dfd-8e1b-3a623088b78f</a:MessageID>
<a:ReplyTo>
<a:Address>http://www.w3.org/2005/08/addressing/anonymous</a:Address>
</a:ReplyTo>
</s:Header>
<s:Body>
<GetData xmlns="http://tempuri.org/">
<value>0</value>
<value2>test</value2>
</GetData>
</s:Body>
</s:Envelope>
我在这里缺少什么?异常中没有更多细节。

【问题讨论】:
-
你能分享你的
web.config吗? -
@SohamDasgupta - 嗨。添加了 Web.config。标准的东西。我确实看到状态码是“ProtocolError”。
-
您能否使用 SoapUI 访问该服务?如果是这样,请将其与您正在使用的标头/方法进行比较。
-
我不认为这可能是你试图实现的方式......你必须使用 ChannelFactory 从客户端调用 WCf 服务......但是为什么不使用代理呢?
-
@Viru,我需要能够动态调用 any Web 服务(用户指定 URL、命名空间、参数等)。我可以使用 HttpWebBinding(不安全)来做到这一点,但我们想添加对 wsHttpBinding(安全)的支持。
