jsonserializer

问题 I'm struggling with datetimes a bit. I'm using asp.net mvc api controllers, a microsoft sql server and AngularJS. On some button click I'm sending a JSON formatted date to an api-controller. When I post 2015-11-31 00:00 and I look in Fiddler to see what's really posted, I see that the date is formatted as such: 2015-11-30T23:00:00.000Z. (2015-11-31 - 1 hour UTC+01:00 Amsterdam, Berlin, Ber....) This is perfect because there might be a difference between the timezone the sql server might be in

问题 According to this article, I'd expect to see the fields in my base class at the top of the list of fields when serializing to JSON. However, I'm seeing the fields at the bottom of the list. The ordering is correct within the actual class itself, but not among the hierarchy. What's happening is it's ordering properly with the class, it it's doing the exact reverse of what I'd expect. I'd expect the base classes to have their fields serialized first. I don't want to use the Order=X attribute

问题 Attempting to serialize DrivInfo to a Json string with this code only return the "name" property: DriveInfo dr = new DriveInfo("C"); string json = Newtonsoft.Json.JsonConvert.SerializeObject(dr); The string result is only: {"_name":"C:\"} DrivInfo is sealed so I cannot change anything. Is there a way to do it excluding wrapping? 回答1: The class contains its own custom serialization which specifies that only the _name field should be included. The other properties aren't stored in the class.

问题 I just started to take care of a code developed by other person. It was designed based on Specification pattern using Spring Data and Hibernate. In few words, if I try search using string, boolean or integer fields it works correctly. For instance, when I search/filter with state==SP I got the result and I can see that the diatomite fields are correctly filled in. Also I see hibernate no complaining about invalid data in this case: Copied form my console when I searched succesfully with

问题 I am already storing UTC time in DateTime objects. When I send this across using Json() serializer these dates are again converted to UTC. I don't want this to happen. Please help. 回答1: Check the Kind property of your DateTime objects, maybe they are not marked as UTC then they get converted again. 来源： https://stackoverflow.com/questions/10138562/json-in-mvc-converts-datetime-to-utc-automatically

问题 How can one serialize a model which has a foreign key to Django auth user so that a username can be retrieved? This is what I have tried through Tastypie: def dehydrate(self, bundle): posts = Post.objects.annotate(num_poster = Count('likedby')).order_by('-num_poster') specificpost = posts.get(id__exact=bundle.data['id']) likedList = specificpost.likedby.all()[:7] liked_data = serializers.serialize('python', likedList, fields=('user__username', 'userPic'), use_natural_keys=True) liked_actual =

问题 We are having a web api project and inorder to convert the date time to date and vice versa, we are using DateTimeconverter extended from JsonConverter. We are using this in the form of an attribute for all the required DateTime properties (as shown below): [JsonConverter(typeof(CustomDateConverter))] The CustomDateConverter is as below: public class CustomDateConverter: JsonConverter { private string[] formats = new string[] { "yyyy-MM-dd", "MM/dd/yy", "MM/dd/yyyy", "dd-MMM-yy" }; public

问题 Is there an attribute to prevent Jil from serializing properties that are null ? In Newtonsoft it is : [JsonProperty(NullValueHandling = NullValueHandling.Ignore)] 回答1: For the whole object, the excludeNulls parameter on Options is what you want (many different Options configurations are pre-calced, anything like Options.ExcludeNulls also works). You can control serialization of a single property with Conditional Serialization. (I forgot about this option in my original answer). For example
