Question

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，而是与我正在使用的GSON格式有关，因为它没有形成像“ù”这样的特殊字符，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发布一个带有下面代码和短JSON字符串的JSON字符串都可以正常工作，但是如果JSON字符串的大小更大，那么IIS 7.5响应：

-MODULE_SET_RESPONSE_ERROR_STATUS ModuleName ManagedPipelineHandler 通知128 HttpStatus 400 HttpReason不良请求 HttpSubStatus 0 ErrorCode 0 ConfigExceptionInfo 通知 EXECUTE_REQUEST_HANDLER 错误代码 Operazione completata。（为0x0）

我已尝试使用Max.ReceivedMessageSize和Web.Config中的其他大小设置，但没有成功。

这是我的Web.Config文件
