我们有一个在 HTTPS 上运行良好的网络服务,但在 HTTPS 上显示 HTTP 415 错误。 因此,在 HTTP 下,我们可以毫无问题地进行 POST 请求发送和接收 JSON。 当我们在 HTTPS 下尝试同样的操作时,我们得到了服务期望 text/xml insteas of application/json 的错误。 关于在哪里看的任何建议?
如果这很重要,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 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>
更新 2这是失败的端点之一:
<endpoint name="DataServiceSecureEndPoint" address="" binding="basicHttpBinding"
bindingConfiguration="SecureBasicHttpBinding" contract="DvaMfs.WcfService.IDataService" />
WCF可以为HTTP或HTTP提供不同的端点。 我认为这是问题,所以我会把它作为一个“答案”(我希望它可以帮到你):
您的端点名称=“ProductServiceEndPoint”address =“”它在您的基地址公开。 好
您的端点名称=“ProductServiceSecureEndPoint”address =“ProductServiceSecure” bindingConfiguration =“SecureBasicHttpBinding”它在基础“base_address] / ProductServiceSecure”中公开。
所以这个终点:
这是不正确的,因为地址可能是“ProductServiceSecure”
basicHttpBinding不能与JSON一起使用。 如果要使用JSON,请将basicHttpBinding(SOAP)更改为webHttpBinding(REST)。
对于这个问题的解决方案是,在您的请求/响应模型中,有一些类没有默认构造函数,它是无参数的。
最后,我们的后端开发人员更改了端点地址字段并将其路由到特定路径(而不是address =“”)以测试它是否正常工作。 显然,根据他的说法,HTTP和HTTPS端点试图使用相同的地址,但是没有用。 所以他最后评论了HTTP端点并设置了HTTPS端点的地址。
我不知道这是否有意义,因为我不知道WCF。 对我来说,对Apache服务器有一些了解,似乎你应该能够指定一个端点,它不应该基于/链接到用于连接它的协议。
在configfile
在服务标签名称=“namespace.Service”添加则在端点标签
address="" behaviorConfiguration="web" binding="webHttpBinding"
contract="namespace.IService"
并在IService
接口中
[WebInvoke(Method = "POST", UriTemplate = "functionname", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)]
