我收到“System.Net.WebException：远程服务器在尝试访问我的WCF方法时返回错误：（400）Bad Request”错误。我认为可能是在客户端。当我使用促销标准工具验证它时，它工作正常http://services.promostandards.org/webserviceValidator/home
以下是来自WCF和客户的信息。

你缺少两件事。将您的xml包装在soap Envelope中，并为要调用的端点添加SOAPAction标头。在这种情况下，“getProductSellable”：
class Program
{
static void Main(string[] args)
{
ASCIIEncoding encoding = new ASCIIEncoding();
string SampleXml = @"<s:Envelope xmlns:s=""http://schemas.xmlsoap.org/soap/envelope/"">
<s:Body xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"">
<GetProductSellableRequest xmlns=""http://www.promostandards.org/WSDL/ProductDataService/1.0.0/"">
<wsVersion xmlns=""http://www.promostandards.org/WSDL/ProductDataService/1.0.0/SharedObjects/"">1.0.0</wsVersion>
<id xmlns=""http://www.promostandards.org/WSDL/ProductDataService/1.0.0/SharedObjects/"">Token1</id>
<password xmlns=""http://www.promostandards.org/WSDL/ProductDataService/1.0.0/SharedObjects/"">Token1</password>
<productId xmlns=""http://www.promostandards.org/WSDL/ProductDataService/1.0.0/SharedObjects/"">Token1</productId>
<partId xmlns=""http://www.promostandards.org/WSDL/ProductDataService/1.0.0/SharedObjects/"">token1</partId>
<isSellable xmlns=""http://www.promostandards.org/WSDL/ProductDataService/1.0.0/SharedObjects/"">true</isSellable>
</GetProductSellableRequest>
</s:Body>
</s:Envelope>";
try
{
byte[] data = encoding.GetBytes(SampleXml);
string url = "http://api.proactiveclothing.com/services/Product.svc";
HttpWebRequest webrequest = (HttpWebRequest)WebRequest.Create(url);
webrequest.Method = "POST";
webrequest.Headers.Add("SOAPAction", "getProductSellable");
webrequest.ContentType = "text/xml";
webrequest.ContentLength = data.Length;
using (Stream newStream = webrequest.GetRequestStream())
{
newStream.Write(data, 0, data.Length);
using (WebResponse response = webrequest.GetResponse())
using (Stream responseStream = response.GetResponseStream())
{
StreamReader sr = new StreamReader(responseStream);
string s = sr.ReadToEnd();
Console.WriteLine(s);
}
}
}
catch (WebException webex)
{
Console.WriteLine(webex.Message);
}
Console.ReadKey();
}
}
对于您的PHP客户端，您可以执行以下操作：使用位于此处的WSDL：http://api.proactiveclothing.com/wsdl/ProductDataService.wsdl （但是，如果你向他们提供wsdl，他们应该知道如何做到这一点）
