JsonProperty似乎不能在windows azure应用程序服务上工作
本文关键字:应用程序 服务 工作 azure windows 不能 JsonProperty | 更新日期: 2023-09-27 18:05:57
我有一个托管在Microsoft Azure云上的应用程序。这个应用程序是一个应用服务。我目前在JSON序列化方面有一些问题。收到的JSON格式不正确。我的应用程序是一个ASP。净MVC6。基本上,我有一个前端,它从控制器(服务器端)接收JSON值。
c#服务器端方法:[HttpGet]
[Route("domain/search")]
public IActionResult Search(string sn)
{
// DOING MY STUFF
ICollection<MyModel> myobject
return new ObjectResult(myobject);
}
模型类:
public class MyModel
{
[JsonProperty(PropertyName = "id", NullValueHandling = NullValueHandling.Ignore)]
public string Id { get; set; }
[JsonProperty(PropertyName = "sn", NullValueHandling = NullValueHandling.Ignore)]
public string SerialNumber { get; set; }
[JsonProperty(PropertyName = "state", NullValueHandling = NullValueHandling.Ignore)]
public AStateTypeModel? State { get; set; }
[JsonProperty(PropertyName = "description", NullValueHandling = NullValueHandling.Ignore)]
public string Description { get; set; }
.
.
ETC
.
.
}
正确接收JSON:
[
{
"id":"806c76b5-guid-guid-guid-guid",
"sn":"X00000000000",
"state":"AState",
.
.
ETC
.
.
}
]
当我在本地模式下启动应用程序时,一切正常。我有正确的JSON值和属性名。但是在Azure上,前端接收到一个错误的JSON:
[
{
"Id":"806c76b5-guid-guid-guid-guid",
"SerialNumber":"X00000000000",
"Description":null,
"State":1,
.
.
ETC
.
.
}
]
我认为这是我的本地和Azure服务器上的包版本不同,但一切看起来都很好。JsonProperty
属性似乎被忽略了。我目前使用的是Windows Azure SDK 2.8, Newtonsoft 9.0.1。和AspNet。Mvc 6.0.0:
依赖性:
"dependencies": {
"Microsoft.AspNet.Server.Kestrel": "1.0.0-*",
"Microsoft.AspNet.IISPlatformHandler": "1.0.0-*",
"Microsoft.AspNet.Mvc": "6.0.0-*",
"Microsoft.AspNet.Mvc.TagHelpers": "6.0.0-*",
"Microsoft.AspNet.Tooling.Razor": "1.0.0-*",
"Microsoft.AspNet.StaticFiles": "1.0.0-*",
"Microsoft.AspNet.Hosting.Abstractions": "1.0.0-*",
"Microsoft.AspNet.Diagnostics": "1.0.0-*",
"Microsoft.AspNet.Http.Abstractions": "1.0.0-rc1-final",
"Microsoft.AspNet.Owin": "1.0.0-rc1-final",
"Microsoft.AspNet.SignalR.Redis": "2.2.0",
"Microsoft.AspNet.WebSockets.Server": "1.0.0-rc1-final",
"Microsoft.AspNet.Authentication.Cookies": "1.0.0-rc1-final",
"Microsoft.AspNet.Authentication.OpenIdConnect": "1.0.0-rc1-final",
"Newtonsoft.Json": "9.0.1"
}
我不知道我是否有一些问题与JsonFormatter
或类似的东西…怎么了?非常感谢你的帮助!
在我看来,您的enum在本地模式下被序列化为string
,在部署到Azure时被序列化为int
。您可以在枚举上放置一个[JsonConverter(typeof(StringEnumConverter))]
属性,以确保它被序列化为string
。
如果你想要string
序列化默认值,你可以设置Json。. NET默认属性如下:
JsonConvert.DefaultSettings = () => new JsonSerializerSettings
{
Converters =
{
new StringEnumConverter
{
CamelCaseText = true
}
}
};
确保你的控制器使用Json。. NET中,您可以重载控制器中的标准Json()
方法,并使用Json(myobject)
代替ObjectResult(myobject)
:
protected override JsonResult Json(object data, string contentType, Encoding contentEncoding, JsonRequestBehavior behavior)
{
return new JsonNetResult(base.Json(data, contentType, contentEncoding, behavior));
}
private class JsonNetResult : JsonResult
{
public JsonNetResult()
{
this.ContentType = "application/json";
}
public JsonNetResult(JsonResult existing)
{
this.ContentEncoding = existing.ContentEncoding;
this.ContentType = !string.IsNullOrWhiteSpace(existing.ContentType) ? existing.ContentType : "application/json";
this.Data = existing.Data;
this.JsonRequestBehavior = existing.JsonRequestBehavior;
}
public override void ExecuteResult(ControllerContext context)
{
if (context == null)
{
throw new ArgumentNullException("context");
}
if ((this.JsonRequestBehavior == JsonRequestBehavior.DenyGet) && string.Equals(context.HttpContext.Request.HttpMethod, "GET", StringComparison.OrdinalIgnoreCase))
{
base.ExecuteResult(context); // Delegate back to allow the default exception to be thrown
}
HttpResponseBase response = context.HttpContext.Response;
response.ContentType = this.ContentType;
if (this.ContentEncoding != null)
{
response.ContentEncoding = this.ContentEncoding;
}
if (this.Data != null)
{
// Replace with your favourite serializer.
new Newtonsoft.Json.JsonSerializer().Serialize(response.Output, this.Data);
}
}
}
我关闭了这个帖子,因为从昨天开始,它就正常工作了。我什么也没做,只是摆弄了一下软件包的版本:——Microsoft.AspNet.Mvc——Newtonsoft。Json我想找出原因,但我缺乏线索。
