在asp.net中創建Web服務時刪除xml標記

Question

我正在asp.net中創建一個web服務。 以下是我得到的回應。

<?xml version="1.0" encoding="utf-8"?>
<string xmlns="http://tempuri.org/">{"Question1":"do the like the idea of the first speaker?","Option1":"YES","Option2":"NO","Option3":"NOT SURE","Option4":"","Option5":"","Type":"button","QID":"q1"}</string>

如何從這里刪除xml標簽......任何想法？

[WebMethod(EnableSession = true)]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string GetQuestions()
{
    return new JavaScriptSerializer().Serialize(Biz.BAL.GetQuestions());
}

如果以下內容正確，您可以驗證web.config：

1）“將* .ASMX httphandler重新路由到ScriptHandlerFactory”

    <httpHandlers>
        <remove path="*.asmx" verb="*"/>
        <add path="*.asmx" verb="*" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
        <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
        <add verb="GET,HEAD" path="ScriptResource.axd" validate="false" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
    </httpHandlers>

2）“Json序列化”您可以將jsonSerialisation設置添加到web.config以確保Json序列化有效：

    <configSections>
    <sectionGroup name="system.web.extensions" type="System.Web.Configuration.SystemWebExtensionsSectionGroup, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
        <sectionGroup name="scripting" type="System.Web.Configuration.ScriptingSectionGroup, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
            <section name="scriptResourceHandler" type="System.Web.Configuration.ScriptingScriptResourceHandlerSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication"/>
            <sectionGroup name="webServices" type="System.Web.Configuration.ScriptingWebServicesSectionGroup, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
                <section name="jsonSerialization" type="System.Web.Configuration.ScriptingJsonSerializationSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="Everywhere"/>
                <section name="profileService" type="System.Web.Configuration.ScriptingProfileServiceSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication"/>
                <section name="authenticationService" type="System.Web.Configuration.ScriptingAuthenticationServiceSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication"/>
                <section name="roleService" type="System.Web.Configuration.ScriptingRoleServiceSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication"/></sectionGroup></sectionGroup></sectionGroup>
    </configSections>

Answer 2

請在Web方法中使用這些行：

---

 JavaScriptSerializer Machinejson = new JavaScriptSerializer();
            this.Context.Response.AppendHeader("Access-Control-Allow-Origin", "*");
            this.Context.Response.ContentType = "application/json; charset=utf-8"; // to remove xml tag from response
            this.Context.Response.Write(Machinejson.Serialize([Object or string to return in form of json)]));

Answer 3

使用此代碼是安全和方便的：ASP

var X = new XmlDocument();
X.LoadXml(YOUR_RESPONSE);
return X.DocumentElement.InnerText;

在Javascript中我認為你應該做這樣的事情

var start = YOUR_RESPONSE.indexOf('<string ');
start = YOUR_RESPONSE.indexOf('>', start)+ 1;
YOUR_RESPONSE.substring(start, YOUR_RESPONSE.lastIndexOf('</string>'));
