A bug of Spring REST Client 1.0: Silverlight don't allow to custom HEADER when GET

[the3rd]

I try:

RestTemplate rt = new RestTemplate("http://localhost:8080");
            rt.MessageConverters.Add(new XElementHttpMessageConverter());
            rt.GetForMessageAsync<XElement>("/modelbuilder/services/modeldefine", r =>
                {
                    if (r.Error == null)
                    {
                        Debug.WriteLine(r.Response.Body.ToString());
                    }
                    else
                    {
                        Debug.WriteLine(r.Error);
                    }
                });

Result:

System.NotSupportedException ---> System.NotSupportedException: 不支持所指定的方法。
   位于 System.Net.Browser.BrowserHttpWebRequest.InternalEndGetResponse(IAsyncResult asyncResult)
   位于 System.Net.Browser.BrowserHttpWebRequest.<>c__DisplayClass5.<EndGetResponse>b__4(Object sendState)
   位于 System.Net.Browser.AsyncHelper.<>c__DisplayClass4.<BeginOnUI>b__1(Object sendState)
   --- 内部异常堆栈跟踪的结尾 ---
   位于 System.Net.Browser.AsyncHelper.BeginOnUI(SendOrPostCallback beginMethod, Object state)
   位于 System.Net.Browser.BrowserHttpWebRequest.EndGetResponse(IAsyncResult asyncResult)
   位于 Spring.Http.Client.WebClientHttpRequest.ExecuteResponseCallback(IAsyncResult result)

I google：

Silverlight only supports setting headers using the POST method not the GET method.

So add some code to "ExecuteAsync" of "WebClientHttpRequest.cs"

// Prepare
                if (this.Method != HttpMethod.GET)
                {
                    this.PrepareForExecution();
                }

All ok.

Hi,

This is the default .NET behavior see :
http://msdn.microsoft.com/en-us/libr...(v=VS.96).aspx

To make this work, you need to change to Client HTTP handling :

((WebClientHttpRequestFactory)rt.RequestFactory).WebRequestCreator = WebRequestCreatorType.ClientHttp;

Thank you, Bruno Baia.

Could you change the default setting for Silverlight?
It will be more pleasure for beginners.

Hi,

I detected a bug, on a windows phone project, that can be related to your case :
https://jira.springsource.org/browse/SPRNETREST-4

I don't think we should change the default behavior to remain consistent with Microsoft implementation.
I will document use of Browser or Client HTTP Handling for silverlight applications :
https://jira.springsource.org/browse/SPRNETREST-5
