【中文标题】wcf 服务不允许 POST【英文标题】：wcf service doesn't allow POST 【发布时间】：2012-06-11 10:39:52 【问题描述】：

一般来说，我对 webervices 还是很陌生，并且陷入了（我认为）配置 IIS 和 web 服务本身的困境。

我在 MVS 2010 中创建了一个 wcf 网络服务，并将其托管在 Windows 7 上的 IIS7.5 上。我使用soapUI 4.5.0 发布一条消息，该消息由我创建webservice 合同时使用的相同wsdl 描述生成。问题是我得到 405，因为 web 服务或 web 服务器似乎不支持 http POST。

尽管我知道我得到的错误足以解决我的问题，但我对 IIS 和 Web 服务的了解不足，使我无法找到正确的解决方案。

低于我能想到的尽可能多的信息。希望它有任何帮助，有人可以指导我正确的方向。

在 IIS 中进行的配置：

授权规则：允许，所有用户

目录浏览：启用处理程序映射：功能权限：读取、脚本和执行处理程序映射：添加 *.wsdl -> ProtocolSupportModule -> GET、HEAD、OPTIONS、TRACE、POST 应用程序池：添加了具有身份 NetworkService 的条目，使用 .net fw 4.0

这是发送的消息：

原始： POST http：x.x.x.x:21378/HTTP/1.1 接受编码：gzip,deflate 内容类型：application/soap+xml;charset=UTF-8;action="/BootNotification"

XML：

<soap:Envelope xmlns:soap="org/2003/05/soap-envelope" xmlns:ns="urn://Ocpp/Cs/2012/02/">
   <soap:Header/>
   <soap:Body>
      <ns:bootNotificationResponse>
         <ns:status>Accepted</ns:status>
         <ns:currentTime>$now</ns:currentTime>
         <ns:heartbeatInterval>900</ns:heartbeatInterval>
      </ns:bootNotificationResponse>
   </soap:Body>
</soap:Envelope>

这是返回的结果：

这是生成的服务合同的一部分（wsdl /language:CS /serverInterface

【参考方案1】：

我不了解您的服务是如何构建的以及您在那里做了什么，但根据我的经验，这是创建支持 POST 请求的 wcf RESTful 服务的简单方法：

http://www.codeproject.com/Articles/201901/CREATE-RESTful-WCF-Service-API-Using-POST-Step-By

根据 cmets 更新：

尝试使用它：

[OperationContract]
[WebInvoke(Method = "POST")]
[System.Web.Services.Protocols.SoapHeaderAttribute("chargeBoxIdentity")]
[System.Web.Services.WebMethodAttribute()]
[System.Web.Services.Protocols.SoapDocumentMethodAttribute("/BootNotification", RequestElementName = "bootNotificationRequest", RequestNamespace = "urn://Ocpp/Cs/2010/08/", ResponseElementName = "bootNotificationResponse", ResponseNamespace = "urn://Ocpp/Cs/2010/08/", Use = System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle = System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
[return: System.Xml.Serialization.XmlElementAttribute("status")]
RegistrationStatus BootNotification(string chargePointVendor, string chargePointModel, string chargePointSerialNumber, string chargeBoxSerialNumber, string firmwareVersion, string iccid, string imsi, string meterType, string meterSerialNumber, out System.DateTime currentTime, [System.Xml.Serialization.XmlIgnoreAttribute()] out bool currentTimeSpecified, out int heartbeatInterval, [System.Xml.Serialization.XmlIgnoreAttribute()] out bool heartbeatIntervalSpecified);

更新

尝试这样做：

在 IIS 7.5 上 -> YourWebsite -> 处理程序映射

选择面板右侧的“添加模块映射”选项

在“请求路径”字段中输入 *.wsdl

在“模块”字段中输入“ProtocolSupportModule”

点击“请求限制”并转到动词选项卡

输入 POST 动词

保存更改

【讨论】：

感谢您的快速响应。该链接很有帮助，我以前看过，但无法将其链接到我的问题。我会更仔细地研究它。我在帖子中添加了部分生成的合同。我不确定，但请尝试在 [OperationContract] 属性下添加 '[WebInvoke(Method = "POST")]' 属性我会尝试并整理出 webhttpbinding ict wshttpbinding 和 basichttpbinding。不知道具体的区别是什么。我添加了属性，但对结果没有影响。响应仍然只告诉我：允许：GET、HEAD、OPTIONS、TRACE 是允许的。我也有这样的想法，不是网络服务在回复这个，而是网络服务器。这可能吗？网络服务器不让网络服务处理帖子，而是将其过滤掉？我确实在处理程序映射中配置了 *.wsdl。

以上是关于wcf 服务不允许 POST的主要内容，如果未能解决你的问题，请参考以下文章

WCF POST 方法返回“方法不允许”

Wcf 中的 WebInvoke POST“方法不允许”

WCF REST 服务为 POST 返回 405

WCF RESTful 应用程序 PUT、POST、DELETE 收到相同的错误：“该方法不允许。”

在带有 Wcf 服务的 Angular JS 的预检响应中，Access-Control-Allow-Methods 不允许方法 PUT

WCF 服务返回“方法不允许”
