Hi,
I want create a WCF Web Service that uses HTTP post instead of the standard SOAP xmls, looking through the internet I managed to make it work with HTTP GET, but I am having some trouble getting the HTTP POST working.
This is my server code:
<div style="color:black; background-color:white
<pre>[ServiceContract(Namespace = <span style="color:#a31515 "http://myCompany.com.br/MyCompany/Test")]<br/> <span style="color:blue public <span style="color:blue interface HTTPPostTest<br/> {<br/> [OperationContract]<br/> <span style="color:blue byte[] WS_HttpPostTest(<span style="color:blue string request);<br/> }<br/>[/code]


<div style="color:black; background-color:white
<pre><span style="color:blue public <span style="color:blue class HTTPostTestImpl : HTTPostTest
{
<span style="color:blue public HTTPostTestImpl()
{

}

<span style="color:blue public <span style="color:blue byte[] WS_HttpPostTest(<span style="color:blue string request)
{
<span style="color:blue byte[] resultadoConsulta;

resultadoConsulta = <span style="color:blue new <span style="color:blue byte[11];

resultadoConsulta[0] = 1;
resultadoConsulta[1] = 1;
resultadoConsulta[2] = 1;
resultadoConsulta[3] = 0;
resultadoConsulta[4] = 1;
resultadoConsulta[5] = 0;
resultadoConsulta[6] = 0;
resultadoConsulta[7] = 0;
resultadoConsulta[8] = 0;
resultadoConsulta[9] = 0;
resultadoConsulta[10] = 4;

<span style="color:blue return resultadoConsulta;
}
}
[/code]


This is the web.config:

<div style="color:black; background-color:white
<pre><span style="color:blue <?<span style="color:#a31515 xml <span style="color:red version<span style="color:blue =<span style="color:black "<span style="color:blue 1.0<span style="color:black "<span style="color:blue ?>

This is my client code:

<div style="color:black; background-color:white
<pre> WebRequest webRequest = WebRequest.Create(<span style="color:#a31515 "http://localhost:8889/HttpPostTest/Service.svc/WS_HttpPostTest");
webRequest.ContentType = <span style="color:#a31515 "application/x-www-form-urlencoded";
webRequest.Method = <span style="color:#a31515 "POST";
<span style="color:blue string data = <span style="color:#a31515 "request=" + Convert.ToString(1231234);
<span style="color:blue byte[] bytes = Encoding.ASCII.GetBytes(data);
Stream os = <span style="color:blue null;
<span style="color:blue try
{ <span style="color:green // send the Post
Console.WriteLine(<span style="color:#a31515 "Enviando pedido");
webRequest.ContentLength = bytes.Length; <span style="color:green //Count bytes to send
os = webRequest.GetRequestStream();
os.Write(bytes, 0, bytes.Length); <span style="color:green //Send it
}
<span style="color:blue catch (WebException ex)
{
Console.WriteLine(<span style="color:#a31515 "HttpPost: Request error: " + ex.Message);
Console.WriteLine(ex.StackTrace);
}
<span style="color:blue finally
{
<span style="color:blue if (os != <span style="color:blue null)
{
os.Close();
}
}

<span style="color:blue try
{ <span style="color:green // get the response
WebResponse webResponse = webRequest.GetResponse();
<span style="color:blue if (webResponse != <span style="color:blue null)
{
StreamReader sr = <span style="color:blue new StreamReader(webResponse.GetResponseStream());

Console.WriteLine(<span style="color:#a31515 "Valor recebido: " + sr.ReadToEnd().Trim());
}
<span style="color:blue else
Console.WriteLine(<span style="color:#a31515 "Nenhum valor recebido");
}
<span style="color:blue catch (WebException ex)
{
Console.WriteLine(<span style="color:#a31515 "HttpPost: Response error: " + ex.Message);
Console.WriteLine(ex.StackTrace);
}
[/code]

When I run this test program I get the following error:

<pre>Enviando pedido
HttpPost: Response error: O servidor remoto retornou um erro: (400) SolicitaÃÃo Incorreta. <br/>[/code]

What am I doing wrong in this program?
Thanks,<br/>
