WCF 数据服务对 POST 查询返回 400 Bad Request

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 服务的读取访问工作正常，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，我从 http 下载了示例 odata 服务://www.odata.org/developers/odata-sdk#/media/7582/odatasampleservices.zip。当在单独的 IIS 网站中运行该 Web 服务时，发布到该 Web 服务可以正常工作。但是，当我将其放入旧网站时，再次向服务发送发布请求时收到 400 Bad Request 错误。

因此，问题似乎与我的 ASP.NET MVC 项目的配置有关。但是，我不知道如何继续。

这是我在旧项目中使用的 Web 配置文件：

编辑： 不确定是否有任何帮助，但这是 fiddler 输出和失败的请求跟踪：

我保存了由于 StackOverflow 不允许帖子增长，因此无法将 Pastebin 请求跟踪到 http://pastebin.com/K3uEZfVS 5万。

编辑2：我想再次指出，当将相同的 Web 服务放入全新的 ASP.NET MVC 网站而不进行其他更改时，它运行良好（POST 和 GET！）。因此，该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 WCF 服务的代码中未设置相应的属性（默认为 AspNetCompatibilityRequirementsMode.NotAllowed），则服务将拒绝来自任何将 aspNetCompatibilityEnabled 设置为 true 的客户端的调用。

• 如果该设置有问题，请在此处
  是长期修复，我添加了
  属性
  [AspNetCompatibilityRequirements（RequirementsMode）
= AspNetCompatibilityRequirementsMode.Allowed)]
  到我的 WCF 服务类

Answer 2

我通过实施网络服务代理解决了这个问题：http://code.google.com /p/fastajaxproxy/

Answer 3

在 IIS 中禁用 WebDav。它对我有用...大多数时候，post 方法用于执行删除或放置操作。禁用此功能使 post 能够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 上传大文件时出现问题，托管在 IIS

（以及以下答案）。

希望这有帮助

Answer 5

该服务托管在哪个操作系统上？
如果是 Vista 或更高版本，您可以使用 FREB 来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/
您可以运行 Fiddler 来识别来自服务器的 HTTP 错误响应是什么吗？
