Question

在我的本地主机上，我在Windows 7上运行IIS 7.5。在我的生产环境中，我在服务器实体上运行了iis 7。 2008。

当我将我的代码发布到生产并运行我的jQuery ajax调用时，我得到一个XML响应，我期待一个JSON响应。

我使用fiddler来比较两个请求标头，它们是相同的。

编辑：我的服务有[ScriptService]：

[ScriptService]
public class Satellites : System.Web.Services.WebService {

的webmethod：

[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)] 
public List<Satellite> GetSatellites()
{
    List<Satellite> satellites;

    if (!CacheHelper.Get(strSatelliteKey, out satellites))
    {
        //satellites not found so retrieve and add to cache for next lookup.
        satellites = GetLatestSatellites();
        CacheHelper.Add(satellites, strSatelliteKey);

    }

    return satellites;
}

Ajax电话：

$.ajax({
    type: "POST",
    url: "Satellites.asmx/GetSatellites",
    data: "{}",
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function (response) {
        var satellites = response.d;
        //            console.log(satellites);
        $.each(satellites, function (index, satellite) {
            Satellites.Items.push(new Satellites.Satellite(satellite.id, satellite.name, satellite.tle0, satellite.tle1, satellite.tle2));
            UI.ControlPanel.Satellites.create_li(satellite, index);
        });
    },
    failure: function (msg) {
        var message = new UI.ControlPanel.Message("<p>There was an error retrieving source satellite information.</p>", UI.ControlPanel.Message.Type.ERROR);
    }
});

即使我使用JavaScriptSerializer并返回如下所示的字符串，我也会将json包装在带有<string＆gt;的xml标记中。包装JSON数据。

 var s = new System.Web.Script.Serialization.JavaScriptSerializer();
 string resultJs = s.Serialize(result);
 return resultJs;

是什么给出的？是IIS 7吗？修改我在两种环境中的web.config都有：

<httpHandlers>
  <remove verb="*" path="*.asmx"/>
  <add verb="*" path="*.asmx" type="System.Web.Script.Services.ScriptHandlerFactory" validate="false"/>
</httpHandlers>

Answer 1

升级到Server 2008 R2 和 IIS 7.5 为我做了诀窍。

我现在可以删除处理程序，它不会有所作为，因为它是.net 4.0。

应用程序现在按预期输出JSON。我唯一做的就是升级。我什么也没做。

Answer 2

因此生产环境应用程序使用XML而不是JSON。我会

检查两个环境是否具有相同的.NET框架版本。
检查生产环境中的Web.config文件是否有一行引用 ScriptHandlerFactory ，如：

<add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

Answer 3

听起来您的制作网站的目标是旧的2.0 ScriptHandlerFactory。确保该站点在IIS和double check these configuration steps中设置为3.5或4.0站点。

另外，请确保您的Web服务使用[ScriptService]属性进行修饰，而不仅仅是方法本身（实际上没有必要的[ScriptMethod]属性）。

ResponseFormat.Json没有响应生产环境中的JSON
