Question

当我向以下各方发出请求时,我已经犯了411个错误:

接口:

[OperationContract]
[WebInvoke(Method = "POST",
    ResponseFormat = WebMessageFormat.Json,
    BodyStyle = WebMessageBodyStyle.Wrapped,
    UriTemplate = "IncSMS")]
string IncSMS(int ID);

方法:

public void IncSMS(int ID)
{
    var business =
        (from p in _db.Businesses
            where p.BusinessID == ID
            select p).FirstOrDefault();
    business.SMSHits += 1;
    _db.SaveChanges();
}

谁能看到我为什么会犯错误? 所有的得力方法工作,我只得获得POST或PUT服务!

任何想法?

Cheers,

Mike。

Answer 1

这部法典没有任何错误,我试图通过浏览器申请PUT,而不能这样做。你们可以以这种方式而不是PUT的方式测试GETs。 “由于违约,它将履行GET”!

在请假中,你只是“重建者”“要求负责人”一节中的“准则”栏目中的“条码”0http://blog.donnfelker.com/2008/12/04/how-to-rest-services-in-wcf-3-5-part-2-the-post/。

感谢gu,

Answer 2

According to the HTTP Standards, 411 means: 10.4.12 411 Length Required

The server refuses to accept the request without a defined Content- Length. The client MAY repeat the request if it adds a valid Content-Length header field containing the length of the message-body in the request message.

因此,请您通过POST/PUT补充数据,说明数据长度。

Answer 3

POST and PUT operations in WCF REST services require that a Content-Length header be included. The 411 response code is WCF telling you to include that header.
