    copied!<p>I write here because I'm working to transform a PHP webservice client to C# (VS2010).</p> <p>Project are in Framework4 but the web service was added in VS2010 like a web service compatible with Framework2 (Web Reference with WSDL).</p> <p>Actually I'm working only on a classical webservice (a Helloworld test).</p> <p>With the client C# I have no problem I send a text to the web service and the web service responds by returing the text. I have no error in the Apache Server.</p> <p>If I activate the basic authentification in the .htaccess apache server (host the webservice server), so in the client C# I have this error :</p> <p>Exception : WebException Bad Request with state HTTP 400 : Bad Request.</p> <p>In Apache error log I see this line :</p> <pre><code>[Thu Feb 02 23:52:06 2012] [error] [client XX.XX.XX.XX] Invalid URI in request &lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:tns="https://www.domaine.com/api/helloworld/webservices.php?wsdl" xmlns:types="https://www.domaine.com/api/helloworld/webservices.php?wsdl/encodedTypes" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org /2001/XMLSchema"&gt; &lt;soap:Body soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"&gt; &lt;tns:bonjour&gt;&lt;prenom xsi:type="xsd:string"&gt;Toto&lt;/prenom&gt;&lt;/tns:bonjour&gt; &lt;/soap:Body&gt; &lt;/soap:Envelope&gt; POST /api/helloworld/webservices.php HTTP/1.1 </code></pre> <p>.</p> <p>I'm sure is the credentials who are not working because when I try with a false user and password I have always the 400 Bad Request.</p> <p>The code of C# Client are : // We create the webservice WebService mywebservice = new WebService();</p> <pre><code>// We define BASIC Authentication CredentialCache myCredentials = new CredentialCache(); NetworkCredential netCred = new NetworkCredential("User1", "Pass1"); myCredentials.Add(new Uri(mywebservice.Url), "Basic", netCred); myCredentials.PreAuthenticate = true; mywebservice.Credentials = myCredentials; // We define the UserAgent mywebservice.UserAgent = ".NET Framework"; // We call the function of webservice string retour = mywebservice.bonjour("Tata"); // We show the return MessageBox.Show(retour, "Retour de l'API", MessageBoxButtons.OK, MessageBoxIcon.Information); </code></pre> <p>.</p> <p>The .htaccess : # Don't show directory listings for URLs which map to a directory.
