serialization

问题 having JSON from web service, Json Array as a response [3] 0: { id: 2 name: "a561137" password: "test" firstName: "abhishek" lastName: "ringsia" organization: "bbb" }- 1: { id: 3 name: "a561023" password: "hello" firstName: "hello" lastName: "hello" organization: "hello" }- 2: { id: 4 name: "a541234" password: "hello" firstName: "hello" lastName: "hello" organization: "hello" } After Getting Response in JsonArray Getting error while reading Json Object of Json Array : List<User> list = new

问题 I am writing a client server application using boost::asio. I want to transfer a structure from a client to the server. The struct has a few std::wstrings in it. How do I encode the structure in boost::asio::buffer? 回答1: Typically I use boost::asio::streambuf for serializing structures. Message.h #ifndef MESSAGE_H #define MESSAGE_H #include <boost/serialization/string.hpp> #include <string> struct Message { std::string _a; std::string _b; template <class Archive> void serialize( Archive& ar,

问题 I am using C# and XmlSerializer to serialize the following class: public class Title { [XmlAttribute("id")] public int Id { get; set; } public string Value { get; set; } } I would like this to serialize to the following XML format: <Title id="123">Some Title Value</Title> In other words, I would like the Value property to be the value of the Title element in the XML file. I can't seem to find any way to do this without implementing my own XML serializer, which I would like to avoid. Any help

问题 I am intending to serialize and deserialize a hashmap whose key is a string. From Josh Bloch's Effective Java, I understand the following. P.222 For example, consider the case of a hash table. The physical representation is a sequence of hash buckets containing key-value entries. Which bucket an entry is placed in is a function of the hash code of the key, which is not, in general guaranteed to be the same from JVM implementation to JVM implementation. In fact, it isn't even guaranteed to be

问题 I would like to control which properties from my model are serialized to my WebAPI2 JSON response, based on matching a query parameter to an attribute. I mainly want to do this to reduce bandwidth on GETs without causing a proliferation of ViewModel classes. For example: GET /books/1?format=summary public class Book { [SerializeFormat("summary")] public int Id { get; set; } [SerializeFormat("summary")] public string Title { get; set; } public string Contents { get; set; } } or

问题 This is my Type: public class MyObject { public string destAdd { get; set; } public long Time { get; set; } public int maxNumb { get; set; } public Account AccountCredentials { get; set; } public System.String Serialize() { String result = ""; XmlSerializer xs = new XmlSerializer(typeof(MyObject)); MemoryStream ms = new MemoryStream(); xs.Serialize(ms, this); result = System.Text.Encoding.UTF8.GetString(ms.ToArray()); ms.Close(); ms.Dispose(); xs = null; return result; } public static

问题 I'm trying to solve the problem of serializing and deserializing Box<SomeTrait> . I know that in the case of a closed type hierarchy, the recommended way is to use an enum and there are no issues with their serialization, but in my case using enums is an inappropriate solution. At first I tried to use Serde as it is the de-facto Rust serialization mechanism. Serde is capable of serializing Box<X> but not in the case when X is a trait. The Serialize trait can’t be implemented for trait objects

问题 I've been tasked to replace C++ code to Go and I'm quite new to the Go APIs. I am using gob for encoding hundreds of key/value entries to disk pages but the gob encoding has too much bloat that's not needed. package main import ( "bytes" "encoding/gob" "fmt" ) type Entry struct { Key string Val string } func main() { var buf bytes.Buffer enc := gob.NewEncoder(&buf) e := Entry { "k1", "v1" } enc.Encode(e) fmt.Println(buf.Bytes()) } This produces a lot of bloat that I don't need: [35 255 129 3

问题 Now i'm working with Jackson and i have some questions about it. First of all. I have two services, first is data collecting and sending service and second receive this data and, for example, log it into a file. So, first service has class hierarchy like this: +----ConcreteC | Base ----+----ConcreteA | +----ConcreteB And second service has class hierarchy like this: ConcreteAAdapter extends ConcreteA implements Adapter {} ConcreteBAdapter extends ConcreteB implements Adapter {}

问题 I've some classes A, B, C they all inherit from class BaseClass. I've a String json that contains the json representation of the A, B, C or BaseClass. I want to have some way to deserialize this String to the BaseClass (polymorphic deserialization). Something like this BaseClass base = ObjectMapper.readValue(jsonString, BaseClass.class); jsonString could be Json String representation of any of A, B, C, or BaseClass. 回答1: It's not clear what problem the original poster is having. I'm guessing
