我可以使用一些帮助,因为我已经被困了2天了。我用谷歌搜索,但未能找到正确的解决方案。
任何人都可以帮忙解决问题,或者如何更好地调试?
发送给localhost的内容
POST /Service1.svc/addt HTTP/1.1
Content-Type: application/json
Host: localhost.:13309
Content-Length: 25

GET操作正常,所以我觉得POST操作确实是错误的。
有关Web.config和Post操作
下面的信息string requestData = "{\"ID\":1,\"Make\":\"Ferrari\"}";
byte[] data = Encoding.UTF8.GetBytes(requestData);
request = (HttpWebRequest)WebRequest.Create("http://localhost.:13309/Service1.svc/addt");
request.Method = "POST";
request.ContentType = "application/json";
request.ContentLength = data.Length;
Stream dataStream = request.GetRequestStream();
dataStream.Write(data, 0, data.Length);
dataStream.Close();
WebResponse webr = request.GetResponse();

自己解决 - 从教程中的文件开始,让这些文件工作,然后逐步进行更改,直到我得到所需的结果。
赞美这个Tutorial
结合WCF Post查看400个不良请求中的大量项目,这里有一些指示。
Web.Config似乎不需要太多关注。如果它适用于GET,则很可能已正确配置POST操作
您要发布的正文/数据格式非常烦躁!如果您声称它是JSON,请确保它是正确的JSON。我(天真)的印象是,无论我放入身体的是什么,都会出现在另一端,但服务员会检查,并返回“不良请求”。

您正在询问如何更好地进行调试。我强烈建议不要添加。在localhost
之后。在这种情况下,你很可能会遇到另一个错误。
请参阅“Why don't I see traffic sent to http://localhost or http://127.0.0.1”
最简单的解决方法是使用您的计算机名称作为主机名而不是Localhost或127.0.0.1。因此,举例来说,不要点击http:// localhost :8081 / mytestpage.aspx,而是访问http:// machinename :8081 / mytestpage.aspx。
希望能帮助您捕获与使用POST方法相关的真实错误。

如果您使用NInject激活它,则应使用NinjectServiceHostFactory。
