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'

Question

We have a webservice that works fine on HTTPS but shows the HTTP 415 error on HTTPS. So, under HTTP, we can make a POST request sending and receiving JSON without issue. When we try the same under HTTPS we got the error that the service is expecting text/xml insteas of application/json. Any suggestion on where to look?

The server is using a self signed certificate if that matters.

  </service>

Update 2 This is one of the endpoints failing:

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

Answer 1

WCF can have different endpoints for HTTP or HTTPs. I think this is the problem, so I will put it as an "answer" (I hope it helps you):

Your endpoint name="ProductServiceEndPoint" address="" it's exposed at your base address. OK

Your endpoint name="ProductServiceSecureEndPoint" address="ProductServiceSecure" bindingConfiguration="SecureBasicHttpBinding" it's exposed at base "base_address]/ProductServiceSecure".

So this endpoint:

• endpoint name="DataServiceSecureEndPoint" address="" binding="basicHttpBinding" bindingConfiguration="SecureBasicHttpBinding"

It's incorrect, because the address may be "ProductServiceSecure"

Answer 2

The basicHttpBinding can not work with JSON. Change the basicHttpBinding (SOAP) to webHttpBinding (REST) if you want to use JSON.

Answer 3

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。

Answer 4

At the end our back-end developer changed the endpoint address field and routed it to specific paths (instead of address="") to test if it was working and it was. Apparently, according to what he said, the HTTP and HTTPS endpoints were trying to use the same address and that wasn't working. So he finally commented the HTTP endpoints and set the address for the HTTPS ones.

I don't know if that make much sense since I have no idea about WCF. To me, having some knowledge on Apache servers, it seems that you should be able to specify an endpoint and it shouldn't be based on/linked to the protocol used for connecting to it.

Answer 5

In configfile add in service tag name="namespace.Service" then in endpoint tag

address="" behaviorConfiguration="web" binding="webHttpBinding"
     contract="namespace.IService"

and in IService interface

[WebInvoke(Method = "POST", UriTemplate = "functionname", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)]
