来自网络服务的响应：方法不允许

Question

I have a .net web service with the following OperationContract:

    [OperationContract]
    [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "testing2?coName={coName}&password={password}")] 
    string testing2(string coName, string password);   

when trying to access it from my local host:

http://.../service1.svc/testing2?coName=abcd&password=1234qw

(... is my local host)

I get the following response in my browser:

Service

Method not allowed.

Answer 1

If you want to invoke a method that expects type POST, you should POST it, or else it won't register correctly. If you're invoking such method by visiting its URL, it will deny the access (that's GET method, that's why it worked previously). If you're not actually posting some data in the body, switch back to GET if you want to invoke it by using an URL.

Answer 2

Try enable anonymous access on this webservice

<security>
 <authentication>
  <anonymousAuthentication enabled="true" />
 </authentication>
</security>

Answer 3

Method not allowed has error code HTTP error code 405. The Possible reason you are getting is because of missing Request property Accept. I really don't want to give you an incorrect code, because I don't know wcf, but this is what you can do once you set a connection,

connection.setRequestProperty("Accept", "*/*");

You need to find similar method that can achieve this task in wcf.

Read this page for more information.

The other reason is if that particular method POST is not allowed on the webservice end, that's when you will get method not allowed.
