POWCF DataServices Service Operation Parameter - Character Replacement
text
Body
copied!<p>I've a very strange problem (using SL5, WCF DataServices 5.0.1): I've a ServiceOperation with 2 String parameters (Username, Password) which checks if the users exists</p> <pre><code>public IQueryable<User> Login(string username, string password) {...} </code></pre> <p>When I try to call this everythings works fine, except the case that the password-hash contains a '+' character in it. In this case, it seems if it is replaced by a whitespace-character:</p> <pre><code>var pwd = CRQWKrKzCcQVnlhk2zl0j5QM+c5ujQGMv0XXnh4genI= this.Context.BeginExecute<User>(new Uri(string.Format("/Login?username='{0}'&password='{1}'", username, pwd), UriKind.Relative), (ar) => { .. }, null); </code></pre> <p>If I grab that with Fiddler, the Request-Header seems ok to me...</p> <pre><code>GET /Service.svc/Login?username='xyz'&password='CRQWKrKzCcQVnlhk2zl0j5QM+c5ujQGMv0XXnh4genI=' HTTP/1.1 </code></pre> <p>But in the WebForms-Tab the Password-QueryString already has a whitespace instead of the '+'. Same result if I debug that on the Server...</p> <p>Does anyone of you know why the '+' is replaced? Are there other invalid characters? How can I avoid that?</p> <p><b>Update/EDIT :</b></p> <p>Surprisingly the following query works as expected:</p> <pre><code>var query = (DataServiceQuery<User>) from c in this.Context.Users where c.Username.Equals(username.ToLower()) && c.Password.Equals(Cryptography.ComputeSha256Hash(password + username.ToLower())) select c; </code></pre> <p>Thanks in advance!</p>
