Question

我需要托管WCF数据服务，作为在IIS 7集成模式下运行的旧版ASP.NET MVC网站的一部分。

对Web服务的读取权限正常，但每当我尝试POST到Web服务时，都会收到400 Bad Request错误。

出于测试目的，我已从http://www.odata.org/developers/odata-sdk#/media/7582/odatasampleservices.zip下载了示例odata服务。在单独的IIS网站中运行时，发布到该Web服务可以正常工作。但是，当我把它放在我的遗留网站中时，我发现400 Bad Request错误会再次向服务发送一个帖子请求。

因此问题似乎与我的ASP.NET MVC项目的配置有关。但是，我对如何进行感到茫然。

这是我在旧项目中使用的网络配置文件：

编辑：不确定它是否是任何帮助，但这里是fiddler输出和失败的请求跟踪：

我将失败的请求跟踪保存到了http://pastebin.com/K3uEZfVS，因为StackOverflow不允许帖子增长超过50k。

Edit2：我想再次指出，当将其放入一个全新的ASP.NET MVC网站而没有其他更改时，同样的Web服务运行正常（POST和GET！）。因此，问题与我提出请求的方式无关。

Answer 1

您是否尝试过在上面发布的web.config中将aspNetCompatibilityEnabled设置为false？

如果未在WCF服务的代码中设置相应的属性（默认为AspNetCompatibilityRequirementsMode.NotAllowed），则该服务拒绝来自任何已将aspNetCompatibilityEnabled设置为true的客户端的调用。

如果该设置是问题，请点击此处我补充说，这是长期的解决方案 attribute [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] 到我的WCF服务类

Answer 2

我通过实现Web服务的代理来解决这个问题：http://code.google.com/p/fastajaxproxy/

Answer 3

在IIS中禁用WebDav。它适用于我...大多数情况下，post方法用于执行删除或放置操作。禁用此功能可使post执行删除和放置操作

Answer 4

如果您要发布文件，请查看此问题中建议的设置：WCF problem with uploading large file, hosted in IIS

（及以下回答）。

希望这有帮助

Answer 5

此服务托管在哪个O / S上？如果是Vista或更高版本，您可以使用FREB解码管道中失败的内容。 http://learn.iis.net/page.aspx/266/troubleshooting-failed-requests-using-tracing-in-iis-7/ 你能运行Fiddler来识别服务器的HTTP错误响应吗？

WCF数据服务为POST查询返回400 Bad Request
