WCF Restful services getting error 400 (bad request) when post xml data
- by Wayne Lo
I am trying to self host a WCF services and calling the services via javascript. It works when I pass the request data via Json but not xml (400 bad request). Please help.
Contract:
public interface iSelfHostServices
{
[OperationContract]
[WebInvoke(Method = "POST", UriTemplate = INFOMATO.RestTemplate.hello_post2,RequestFormat = WebMessageFormat.Xml, ResponseFormat = WebMessageFormat.Xml, BodyStyle = WebMessageBodyStyle.Wrapped)]
Stream hello_post2(string helloString);
}
Server side code:
public Stream hello_post2(string helloString)
{
if (helloString == null)
{
WebOperationContext.Current.OutgoingResponse.StatusCode = System.Net.HttpStatusCode.BadRequest;
return null;
}
WebOperationContext.Current.OutgoingResponse.StatusCode = System.Net.HttpStatusCode.OK;
return new MemoryStream(Encoding.UTF8.GetBytes(helloString));
}
JavaScript:
function testSelfHost_WCFService_post_Parameter() {
var xmlString = "<helloString>'hello via Post'</helloString>";
Ajax_sendData("hello/post2", xmlString);
}
function Ajax_sendData(url, data) {
var request = false;
request = getHTTPObject();
if (request) {
request.onreadystatechange = function() {
parseResponse(request);
};
request.open("post", url, true);
request.setRequestHeader("Content-Type", "text/xml; charset=utf-8"); charset=utf-8");
request.send(data);
return true;
}
}
function getHTTPObject() {
var xhr = false;
if (window.XMLHttpRequest) {
xhr = new XMLHttpRequest();
} else if (window.ActiveXObject) {...}
}
