浏览器 JSON 复杂字段兼容 Implementation Plan

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: 让旧 WinForms 浏览器桥接能够把任意对象或数组字段保留为紧凑 JSON 字符串，并继续安全转换为 DataTable。

Architecture: 在 Lskj.Util.JsonUtil 增加一个只供明确调用方选用的转换入口：先扫描整批 JSON 行，确定复杂列，再把这些列统一字符串化，最后复用 Newtonsoft.Json 原有 DataTableConverter。Lskj.Control 只在网页右键和返回行两个边界调用新入口，其他 JSON 转换和 WPF 宿主保持不变。

Tech Stack: .NET Framework 4.0、C# 7.3、Newtonsoft.Json 13.0.1、System.Data.DataTable、MSBuild、无第三方测试框架的控制台回归测试程序。

Global Constraints

保留对象和数组字段，不删除 $styles 或其他未来字段。
复杂值必须转换成无缩进的紧凑 JSON 字符串。
从未出现对象或数组的标量列继续使用现有 Newtonsoft.Json 类型推断。
不修改现有 JsonUtil.ToDataTable 和 JsonUtil.ToDataRow 的语义。
不修改全局 Newtonsoft.Json 设置，不替换项目中的其他 DeserializeObject<DataTable> 调用。
不修改 WPF、数据库、菜单查找、参数替换或 DLL 加载逻辑。
只接入 BsOpenModuleHandler.OpenRightModule 和 BsOpenModuleHandler.AddReturnRow。
现有两个目标源码文件只有 CRLF/LF 换行差异；执行前必须确认没有语义差异，再机械归一化，避免产生整文件噪声提交。

Task 1: 建立回归测试并实现公共转换器

Files:

Create: 插件库/Lskj.Util.Tests/Lskj.Util.Tests.csproj
Create: 插件库/Lskj.Util.Tests/Program.cs
Modify: 插件库/Lskj.Util/JsonUtil.cs:1-190

Interfaces:

Consumes: Newtonsoft.Json JToken、JArray、JObject 和现有 DataTableConverter。
Produces: public static DataTable JsonUtil.ToDataTablePreservingComplexValues(string json)；接受顶层对象或对象数组，返回保留所有字段的 DataTable。
Step 1: 确认目标源码没有未提交的语义改动

Run:

git diff --ignore-space-at-eol --exit-code -- \
  '插件库/Lskj.Util/JsonUtil.cs' \
  '插件库/Lskj.Control/BrowserSetting/BsOpenModuleHandler.cs'

Expected: exit code 0，无输出。当前普通 git diff --numstat 显示的是 CRLF/LF 差异，不代表业务代码变化。

Step 2: 机械归一化两个目标源码的换行符

只有 Step 1 成功后执行：

perl -pi -e 's/\r$//' \
  '插件库/Lskj.Util/JsonUtil.cs' \
  '插件库/Lskj.Control/BrowserSetting/BsOpenModuleHandler.cs'
git diff --check -- \
  '插件库/Lskj.Util/JsonUtil.cs' \
  '插件库/Lskj.Control/BrowserSetting/BsOpenModuleHandler.cs'

Expected: git diff --check 无输出；此时两个文件不再显示整文件换行差异。

Step 3: 创建不依赖测试框架的回归测试项目

Create 插件库/Lskj.Util.Tests/Lskj.Util.Tests.csproj:

Create 插件库/Lskj.Util.Tests/Program.cs:

                return 1;
            }
        }

        private static void PreservesStylesObjectAsCompactJson()
        {
            const string json = "[{\"id\":1,\"$styles\":{\"rowstyle\":\"{color:'#FFFF00','background-color':'#FF0000'}\"}}]";
            DataTable table = JsonUtil.ToDataTablePreservingComplexValues(json);
            AssertEqual(1, table.Rows.Count, "styles row count");

        }

        private static void LeavesScalarColumnsEquivalentToExistingConverter()
        {
            const string json = "[{\"id\":1,\"title\":\"A\",\"active\":true},{\"id\":2,\"title\":\"B\",\"active\":false}]";
            DataTable expected = JsonConvert.DeserializeObject<DataTable>(json);
            DataTable actual = JsonUtil.ToDataTablePreservingComplexValues(json);
            AssertEqual(expected.Columns.Count, actual.Columns.Count, "scalar column count");
            AssertEqual(expected.Rows.Count, actual.Rows.Count, "scalar row count");
            foreach (DataColumn column in expected.Columns)
            {
                AssertEqual(column.DataType, actual.Columns[column.ColumnName].DataType,
                    "scalar column type " + column.ColumnName);
                for (int rowIndex = 0; rowIndex < expected.Rows.Count; rowIndex++)
                {
                    AssertEqual(expected.Rows[rowIndex][column.ColumnName],
                        actual.Rows[rowIndex][column.ColumnName],
                        "scalar value " + column.ColumnName + " row " + rowIndex);
                }
            }
        }

        private static void AcceptsSingleObject()
        {
            const string json = "{\"ProductId\":\"P001\",\"meta\":{\"source\":\"web\"}}";
            DataTable table = JsonUtil.ToDataTablePreservingComplexValues(json);

            throw new InvalidOperationException("Expected " + typeof(TException).Name + ": " + name);

}

Step 4: 构建测试项目并确认它先失败

Run in Windows PowerShell from E:\lserp_project\lserp_cs_6.0:

$msbuild = Get-ChildItem "${env:ProgramFiles(x86)}\Microsoft Visual Studio\2022\*\MSBuild\Current\Bin\MSBuild.exe" |
    Select-Object -First 1 -ExpandProperty FullName
if (-not $msbuild) { $msbuild = "$env:WINDIR\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe" }
& $msbuild "插件库\Lskj.Util.Tests\Lskj.Util.Tests.csproj" /t:Rebuild /p:Configuration=Debug /p:Platform=AnyCPU

Expected: build fails with CS0117 because JsonUtil.ToDataTablePreservingComplexValues does not exist yet. Dependency or SDK errors do not satisfy this step。

Step 5: 实现复杂字段归一化方法

Add using System.Globalization; to 插件库/Lskj.Util/JsonUtil.cs, then add this method to JsonUtil without changing existing methods:

public static DataTable ToDataTablePreservingComplexValues(string json)
{
    if (string.IsNullOrWhiteSpace(json))
    {
        throw new ArgumentException("网页行 JSON 不能为空。", "json");
    }

    JToken root = JToken.Parse(json);
    JArray rows;
    if (root.Type == JTokenType.Array)
    {
        rows = (JArray)root;
    }
    else if (root.Type == JTokenType.Object)
    {
        rows = new JArray(root);
    }
    else
    {
        throw new JsonSerializationException("网页行 JSON 的顶层必须是对象或对象数组。");
    }

    HashSet<string> complexColumns = new HashSet<string>(StringComparer.OrdinalIgnoreCase);
    foreach (JToken rowToken in rows)
    {
        if (rowToken.Type != JTokenType.Object)
        {
            throw new JsonSerializationException("网页行 JSON 数组中的每一项都必须是对象。");
        }

        foreach (JProperty property in ((JObject)rowToken).Properties())
        {
            if (property.Value.Type == JTokenType.Object || property.Value.Type == JTokenType.Array)
            {
                complexColumns.Add(property.Name);
            }
        }
    }

    foreach (JObject row in rows.Children<JObject>())
    {
        foreach (JProperty property in row.Properties().ToList())
        {
            if (!complexColumns.Contains(property.Name)
                || property.Value.Type == JTokenType.Null
                || property.Value.Type == JTokenType.Undefined)
            {
                continue;
            }

            string text;
            if (property.Value.Type == JTokenType.Object || property.Value.Type == JTokenType.Array)
            {
                text = property.Value.ToString(Formatting.None);
            }
            else if (property.Value.Type == JTokenType.String)
            {
                text = property.Value.Value<string>();
            }
            else
            {
                JValue scalar = property.Value as JValue;
                text = scalar == null || scalar.Value == null
                    ? null
                    : Convert.ToString(scalar.Value, CultureInfo.InvariantCulture);
            }

            property.Value = text == null ? JValue.CreateNull() : new JValue(text);
        }
    }

    return JsonConvert.DeserializeObject<DataTable>(rows.ToString(Formatting.None));
}

Step 6: 构建并运行转换级回归测试

& $msbuild "插件库\Lskj.Util.Tests\Lskj.Util.Tests.csproj" /t:Rebuild /p:Configuration=Debug /p:Platform=AnyCPU
if ($LASTEXITCODE -ne 0) { throw "Lskj.Util.Tests build failed" }
& "插件库\Lskj.Util.Tests\bin\Debug\Lskj.Util.Tests.exe"
if ($LASTEXITCODE -ne 0) { throw "Lskj.Util.Tests failed" }

Expected: build succeeds and executable prints PASS: JsonUtil complex-value conversion tests.

Step 7: 提交公共转换器和回归测试

git add \
  '插件库/Lskj.Util/JsonUtil.cs' \
  '插件库/Lskj.Util.Tests/Lskj.Util.Tests.csproj' \
  '插件库/Lskj.Util.Tests/Program.cs'
git diff --cached --check
git commit -m 'fix(util): preserve complex JSON values in data tables'

Expected: commit only contains the new test project and the focused JsonUtil method.

Task 2: 在旧浏览器桥接的两个入口接入转换器

Files:

Modify: 插件库/Lskj.Control/BrowserSetting/BsOpenModuleHandler.cs:101-116
Modify: 插件库/Lskj.Control/BrowserSetting/BsOpenModuleHandler.cs:322-334

Interfaces:

Consumes: JsonUtil.ToDataTablePreservingComplexValues(string json) from Task 1。
Produces: OpenRightModule 和 AddReturnRow 对任意对象/数组字段的兼容行为；其他菜单及模块调用接口不变。
Step 1: 将右键入口切换到公共转换器

Replace:

DataTable dataTable = JsonConvert.DeserializeObject<DataTable>(arrayItem);

with:

DataTable dataTable = JsonUtil.ToDataTablePreservingComplexValues(arrayItem);

Do not change the BaseImpl.GetDataRowResult query, GridRightMenuModel, DynamicModel or menu.ExecRightMenu calls.

Step 2: 将网页返回行入口切换到公共转换器并删除冗余包装

Replace:

JObject rowObject = JsonConvert.DeserializeObject<JObject>(rowdata);
JArray jArray = new JArray();
jArray.Add(rowObject);
DataTable dataTable = JsonConvert.DeserializeObject<DataTable>(JsonConvert.SerializeObject(jArray));

with:

DataTable dataTable = JsonUtil.ToDataTablePreservingComplexValues(rowdata);

Remove the now-unused using Newtonsoft.Json; and using Newtonsoft.Json.Linq;. Keep product-prefix renaming and StaticControl.ReturnRowLisy.Add unchanged.

Step 3: 静态检查浏览器桥接范围

rg -n 'DeserializeObject\s*<\s*DataTable\s*>|ToDataTablePreservingComplexValues' \
  '插件库/Lskj.Control/BrowserSetting/BsOpenModuleHandler.cs'
git diff --check -- '插件库/Lskj.Control/BrowserSetting/BsOpenModuleHandler.cs'

Expected: only two ToDataTablePreservingComplexValues calls remain in this file；没有直接的 DeserializeObject<DataTable>，且 git diff --check 无输出。

Step 4: 重跑转换级测试并构建 Lskj.Control

& "插件库\Lskj.Util.Tests\bin\Debug\Lskj.Util.Tests.exe"
if ($LASTEXITCODE -ne 0) { throw "Lskj.Util.Tests failed" }
& $msbuild "插件库\Lskj.Control\Lskj.Control.csproj" /t:Rebuild /p:Configuration=Debug /p:Platform=AnyCPU
if ($LASTEXITCODE -ne 0) { throw "Lskj.Control build failed" }

Expected: tests print PASS；Lskj.Control build succeeds without new warnings or errors and refreshes Debug\Lskj.Control.dll plus referenced Lskj.Util.dll.

Step 5: 提交浏览器桥接改动

git add '插件库/Lskj.Control/BrowserSetting/BsOpenModuleHandler.cs'
git diff --cached --check
git commit -m 'fix(browser): accept nested values in row callbacks'

Expected: commit only changes the two intended browser callback conversions and removes the two unused Newtonsoft using directives.

Task 3: 最终构建与业务验收交接

Files:

Verify: Debug/Lskj.Util.dll
Verify: Debug/Lskj.Control.dll
Verify: Debug/Ls_NERP.exe

Interfaces:

Consumes: Task 1 的转换器和 Task 2 的浏览器接入。
Produces: 可由用户分别从旧 WinForms 和 WPF 宿主进行验收的 Debug 运行目录。
Step 1: 执行最终自动验证

& $msbuild "插件库\Lskj.Util.Tests\Lskj.Util.Tests.csproj" /t:Rebuild /p:Configuration=Debug /p:Platform=AnyCPU
if ($LASTEXITCODE -ne 0) { throw "Lskj.Util.Tests build failed" }
& "插件库\Lskj.Util.Tests\bin\Debug\Lskj.Util.Tests.exe"
if ($LASTEXITCODE -ne 0) { throw "Lskj.Util.Tests failed" }
& $msbuild "插件库\Lskj.Control\Lskj.Control.csproj" /t:Rebuild /p:Configuration=Debug /p:Platform=AnyCPU
if ($LASTEXITCODE -ne 0) { throw "Lskj.Control build failed" }
Get-Item "Debug\Lskj.Util.dll", "Debug\Lskj.Control.dll" |
    Select-Object FullName, Length, LastWriteTime

Expected: both builds succeed, test executable prints PASS, and both runtime DLL timestamps reflect the current build.

Step 2: 核对最终差异和提交历史

git diff --check
git status --short
git log -4 --oneline --decorate

Expected: no uncommitted implementation changes；历史包含设计提交、公共转换器提交和浏览器桥接提交。构建输出和原有忽略文件不应进入 Git。

Step 3: 交给用户执行业务验收

Provide this exact checklist:

1. 从 WPF 宿主启动，进入同一待办任务页面并点击“待办任务”。
2. 确认不再出现 Path '[0].$styles' / StartObject 的 DataTable 反序列化错误。
3. 确认右键配置继续解析到 PUR_4004，并正常进入原有客户端模块加载流程。
4. 使用一个不包含对象/数组字段的旧网页右键功能，确认行为未变化。
5. 如可用，再从旧 WinForms 入口重复步骤 1-4，确认两个宿主行为一致。
6. 验证网页返回行功能，确认 ProductId 前缀和原有回填逻辑未变化。

No additional source commit is required for this manual acceptance step.
