ResponseFormat.Json 在生产环境中不响应 JSON
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 Server Ent 上运行 iis 7。 2008 年。
当我将代码发布到生产环境并运行 jQuery ajax 调用时，我得到一个 XML 响应，并且我期望一个 JSON 响应。
我用 fiddler 比较了两个请求头，它们是相同的。
编辑：我的服务有[ScriptService]：
[ScriptService]
public class Satellites : System.Web.Services.WebService {
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调用：
$.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);
}
});
来自本地主机的响应：

即使我使用JavaScriptSerializer并返回如下所示的字符串，我也会得到包裹在xml标签中的json带有
var s = new System.Web.Script.Serialization.JavaScriptSerializer();
string resultJs = s.Serialize(result);
return resultJs;
什么给了？是 IIS 7 吗？ 编辑： 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>

升级到 Server 2008 R2 和 IIS 7.5 对我来说成功了。
我现在可以删除处理程序，并且不会产生任何影响，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。
Upgrading to Server 2008 R2 and IIS 7.5 did the trick for me.
I can now remove the handlers and it won't make a difference because it's .net 4.0.
The application now outputs JSON as expected. The only thing i did was the upgrade. I did nothing else.
因此生产环境应用程序使用XML而不是JSON。我会
检查生产环境中的Web.config文件是否有引用ScriptHandlerFactory的行，例如：
<添加动词=“*”路径=“*.asmx”验证=“假”type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
So production environment application uses XML instead of JSON. I would
Check if Web.config file on production environment has a line with reference to ScriptHandlerFactory like:
<add verb="*" path="*.asmx" validate="false"type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
听起来您的生产站点正在针对较旧的 2.0 ScriptHandlerFactory。确保站点在 IIS 中设置为 3.5 或 4.0 站点，并且 仔细检查这些配置步骤。
另外，请确保您的 Web 服务是用 [ScriptService] 属性装饰的，而不仅仅是方法本身（实际上不需要 [ScriptMethod] 属性）。
It sounds like your production site is targeting the older 2.0 ScriptHandlerFactory. Make sure the site is set to a 3.5 or 4.0 site in IIS and double check these configuration steps.
Also, make sure that your web service is decorated with the [ScriptService] attribute, not just the method itself (the [ScriptMethod] attribute there isn't actually necessary).
