HTTP 415 无法处理消息，因为内容类型为“application/json;” charset=utf-8' 不是预期的类型 'text/xml；字符集=utf-8'

我们有一个 Web 服务在 HTTPS 上运行良好，但在 HTTPS 上显示 HTTP 415 错误。因此，在 HTTP 下，我们可以毫无问题地发送和接收 JSON 的 POST 请求。当我们在 HTTPS 下尝试相同的操作时，我们收到错误，该服务需要 text/xml 而不是 application/json。关于去哪里看有什么建议吗？

如果重要的话，服务器正在使用自签名证书。

更新了绑定和行为

服务看起来像这样

<service name="DvaMfs.WcfService.ProductService" behaviorConfiguration="DvaMfs.WcfService">
    <endpoint name="ProductServiceEndPoint" address="" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding" contract="DvaMfs.WcfService.IProductService" />
    <endpoint name="ProductServiceAjaxEndPoint" address="ajax" binding="webHttpBinding" bindingConfiguration="WebHttpBinding" behaviorConfiguration="AjaxBehavior" contract="DvaMfs.WcfService.IProductService" />
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
    <endpoint name="ProductServiceSecureEndPoint" address="ProductServiceSecure" binding="basicHttpBinding" bindingConfiguration="SecureBasicHttpBinding" contract="DvaMfs.WcfService.IProductService" />
    <endpoint name="ProductServiceAjaxSecureEndPoint" address="ProductServiceSecureajax" binding="webHttpBinding" bindingConfiguration="SecureWebHttpBinding" behaviorConfiguration="AjaxBehavior" contract="DvaMfs.WcfService.IProductService" />
  </service>

Update 2这是失败的端点之一：

<endpoint name="DataServiceSecureEndPoint" address="" binding="basicHttpBinding"
bindingConfiguration="SecureBasicHttpBinding" contract="DvaMfs.WcfService.IDataService" />

WCF 可以有不同的 HTTP 或 HTTP 端点。 我认为这就是问题所在，所以我将其作为“答案”（希望对您有帮助）：

Your 端点名称=“ProductServiceEndPoint”地址=“”它暴露在您的基地址处。好的

Your 端点名称=“ProductServiceSecureEndPoint”地址=“ProductServiceSecure”绑定配置=“SecureBasicHttpBinding”
