Question

我使用VB.NET“WCF Rest Service Application”项目模板构建了一个非常简单的Web服务（这是一个不错的选择吗？）。我工作得很好，除了有

的事实

<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">
...
</string>

添加到我的回答中。

我已将我的返回值声明为String：

<WebInvoke(UriTemplate:="member/login", Method:="POST",
            responseformat:=WebMessageFormat.Json, 
            BodyStyle:=WebMessageBodyStyle.Bare)>
Public Function Create(data As IO.Stream) As String

        Dim strData As String = New IO.StreamReader(data).ReadToEnd()
        Dim UserAccessForm As LoginAccess = Me.getAnswer(strData)
        Dim jsonAnswer As String
        jsonAnswer = Newtonsoft.Json.JsonConvert.SerializeObject(UserAccessForm, Newtonsoft.Json.Formatting.None)
        Return jsonAnswer
End Function

所以不要回答这个问题：

{"logged":false,"userID":"0","message":"Empty body"}

我明白了：

<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">
{"logged":false,"userID":"0","message":"Empty body"}
</string>

有什么方法可以避免我的字符串答案的这种不必要的序列化吗？

Answer 1

我遇到了这个问题并通过将XmlSerializerFormat属性应用于服务合同来解决它。

这是一个c＃片段 - 希望它可以帮到你。

[ServiceContract(Namespace = "")]
[XmlSerializerFormat]
interface IHuggies
{
    [OperationContract]
    [WebInvoke(
        Method = "POST",
        UriTemplate = "/CheckIfConsumerExists")]
    bool CheckIfConsumerExists(string parameters);
}

Answer 2

我认为这会有效，请注意Stream作为返回参数。

<WebInvoke(UriTemplate:="member/login", Method:="POST",
            responseformat:=WebMessageFormat.Json, 
            BodyStyle:=WebMessageBodyStyle.Bare)>
Public Function Create(data As IO.Stream) As Stream

        Dim strData As String = New IO.StreamReader(data).ReadToEnd()
        Dim UserAccessForm As LoginAccess = Me.getAnswer(strData)
        Dim jsonAnswer As String
        jsonAnswer = Newtonsoft.Json.JsonConvert.SerializeObject(UserAccessForm, Newtonsoft.Json.Formatting.None)
        Return New  MemoryStream(ASCIIEncoding.Default.GetBytes(jsonAnswer));
End Function

Answer 3

这似乎可行（responseformat.Json是魔术字）：

import 'package:actionhrm/pages/login.dart';
import 'package:flutter/material.dart';
import 'package:flutter_statusbarcolor/flutter_statusbarcolor.dart';
import 'package:flutter/services.dart';




 void main() => runApp(new MyApp());

 class MyApp extends StatelessWidget {

 MyApp() {
   //changeStatusColor(Color(0xFF28ace2));
 }

 changeStatusColor(Color color) async {
   try {
     await FlutterStatusbarcolor.setStatusBarColor(color);
   } on PlatformException catch (e) {
     print(e);
   }
 }

 // This widget is the root of your application.
 @override
 Widget build(BuildContext context) {
   return new MaterialApp(
     theme: new ThemeData(
       primaryColor: Color(0xFF28ace2),
       brightness: Brightness.light,
       accentColor: Colors.white,
       cardColor: Colors.white,

     ),
     home: LoginPage(),
   );
 }
}

Answer 4

我对此进行了大量阅读，并且看起来XML是C＃中的标准响应。我结束了：

$ cat test.sh
ls \
    -l\
    -h
$

Answer 5

public String cleanOUTPUT(String OUTPUT) {
    OUTPUT = OUTPUT.replaceAll("<string xmlns=\"http://schemas.microsoft.com/2003/10/Serialization/\">","");
    OUTPUT = OUTPUT.replaceAll("</string>", "");    
return OUTPUT;
}

如何避免<string xmlns =“http://schemas.microsoft.com/2003/10/Serialization/”>？</string>
