'传入的消息具有意外的消息格式“Raw”。该操作的预期消息格式为“Xml”、“Json”

Question

不知道我错过了什么，但由于某种原因 WCf 不断向我抛出这个错误。

The server encountered an error processing the request. The exception message is 'The incoming message has an unexpected message format 'Raw'. The expected message formats for the operation are 'Xml', 'Json'. This can be because a WebContentTypeMapper has not been configured on the binding. See the documentation of WebContentTypeMapper for more details.'. See server logs for more details. The exception stack trace is:

我的问题是由于无法访问所请求的资源引起的。该消息非常具有误导性。
