我有一个接受 JSON 字符串实体的 WCF 服务，这是方法：

更新：我解决了这个问题，因为这与 WCF 服务无关，而是与我使用的 GSON 格式有关，因为它没有格式化像“ù”这样的特殊字符，并且服务器拒绝接受这个字符。

 <WebInvoke(UriTemplate:="UpdateUser", ResponseFormat:=WebMessageFormat.Json, RequestFormat:=WebMessageFormat.Json, Method:="POST", BodyStyle:=WebMessageBodyStyle.WrappedRequest)> _
Public Function UpdateUser(user As String) As Stream Implements IService1.UpdateUser

End Function

如果我尝试通过 JAVA HttpClient 使用下面的代码和短 JSON 字符串发布 JSON 字符串，则一切正常，但如果 JSON 字符串的大小更大，则 IIS 7.5 响应为：

-MODULE_SET_RESPONSE_ERROR_STATUS ModuleName ManagedPipelineHandler Notification 128 HttpStatus 400 HttpReason Bad Request HttpSubStatus 0 ErrorCode 0 ConfigExceptionInfo Notification EXECUTE_REQUEST_HANDLER ErrorCode Operazione completata。(0x0)

我已经尝试在 Web.Config 中使用 MaxReceivedMessageSize 和其他大小设置，但没有成功。

这是我的 Web.Config 文件
