如何將串列反序列化為'<class'str'>'forSubTaskRuleRes.content，

這是我定義的 dto 類：

using System;
using System.Text.Json;
using System.Text.Json.Serialization;

namespace DeserializeDemo
{
    public class SubTaskRuleDto
    {
        public Guid Id { get; set; }

        [JsonConverter(typeof(ByteArrayConverter))]
        public byte[] Content { get; set; }

        public bool DisableImage { get; set; }

        public bool UseMobileAgent { get; set; }

        public bool SupplementEnable { get; set; }
    }

    public class ByteArrayConverter : JsonConverter<byte[]>
    {
        public override byte[] Read(ref Utf8JsonReader reader, Type typeToConvert, JsonSerializerOptions options)
        {
            short[] sByteArray = JsonSerializer.Deserialize<short[]>(ref reader);
            byte[] value = new byte[sByteArray.Length];
            for (int i = 0; i < sByteArray.Length; i  )
            {
                value[i] = (byte)sByteArray[i];
            }

            return value;
        }

        public override void Write(Utf8JsonWriter writer, byte[] value, JsonSerializerOptions options)
        {
            writer.WriteStartArray();

            foreach (var val in value)
            {
                writer.WriteNumberValue(val);
            }

            writer.WriteEndArray();
        }
    }
}

然后我將展示asp.net核心控制器代碼：

using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Logging;
using System;

namespace DeserializeDemo.Controllers
{
    [ApiController]
    [Route("[controller]")]
    public class Clouds : ControllerBase
    {
        private readonly ILogger<Clouds> _logger;

        public Clouds(ILogger<Clouds> logger)
        {
            _logger = logger;
        }

        [HttpGet]
        public SubTaskRuleDto Get()
        {
            return new SubTaskRuleDto()
            {
                Id = Guid.NewGuid(),
                Content = new byte[] { 1, 7},
                DisableImage = false,
                UseMobileAgent = true,
                SupplementEnable = false,
            };
        }

        public enum ContentType
        {
            Xoml = 1,
            Python = 7,
            NodeJS = 8
        }
    }
}

當我在 python 客戶端呼叫 api 時，我的代碼是這樣的：

# -*- coding:utf-8 -*-
import json
import deserialize
import requests


class SubTaskRuleRes:
    id: str
    content: str
    disableImage: bool
    useMobileAgent: bool
    supplementEnable: bool


def get_subtask_rule():
    url = "http://localhost:5000/clouds"
    res = requests.get(url)

    # print(res.content)
    # binary = res.content
    # output = json.loads(binary)

    my_instance = deserialize.deserialize(SubTaskRuleRes, res.json())
    print(my_instance)

get_subtask_rule()

反序列化 - 1.8.3 - https://github.com/dalemyers/deserialize

問題是我無法將串列反序列化為 '<class 'str'>' 或 SubTaskRuleRes.content 的串列。

uj5u.com熱心網友回復：

deserialize不執行隱式型別轉換。這就是你得到錯誤的原因（注意，總是發布你得到的完整回溯）。

查看檔案，您可以使用裝飾器來傳遞決議器函式（查看Advanced Usage/Parsers，例如

import deserialize

@deserialize.parser("content", str)
class SubTaskRuleRes:
    id: str
    content: str
    disableImage: bool
    useMobileAgent: bool
    supplementEnable: bool
    

def get_subtask_rule():
    spam = {'id':'28631ee-abd', 'content':[1, 7],
            'disableImage': False, 'useMobileAgent':True,
            'supplementEnable': False}
    return deserialize.deserialize(SubTaskRuleRes, spam)

rule = get_subtask_rule()
print(rule.content)
print(type(rule.content))

輸出

[1, 7]
<class 'str'>

請注意，我不確定您為什么要content成為串列文字、字串
