## What does this PR do?

Fixes #4156

When posting form data with file upload, if a field value contains `=`
or `&`, the value was being truncated.

### Example

```go
data := g.Map{
    "file":      "@file:/path/to/file.txt",
    "fieldName": "aaa=1&b=2",
}
client.Post(ctx, "/upload", data)
```

**Expected**: Server receives `fieldName = "aaa=1&b=2"`
**Actual (before fix)**: Server receives `fieldName = "aaa"` (truncated)

## Root Cause Analysis

The issue was caused by three problems in the original code:

### Problem 1: Global URL encoding disable (httputils.go)

```go
// Original code - PROBLEMATIC
if urlEncode {
    for k, v := range m {
        if gstr.Contains(k, fileUploadingKey) || gstr.Contains(gconv.String(v), fileUploadingKey) {
            urlEncode = false  // Disables URL encoding for ALL values!
            break
        }
    }
}
```

When any value contained `@file:`, URL encoding was disabled for ALL
values, causing `"aaa=1&b=2"` to remain unencoded. The `&` character was
then treated as a parameter separator.

### Problem 2: Split on all `=` characters (gclient_request.go)

```go
// Original code - PROBLEMATIC
array := strings.Split(item, "=")  // Splits on ALL '=' characters
```

This caused `"fieldName=aaa=1"` to be split into `["fieldName", "aaa",
"1"]`.

### Problem 3: No URL decoding for field values

URL-encoded values were written directly to the multipart form without
decoding.

## Solution

### Fix 1: Remove global URL encoding disable

Only `@file:` prefixed values are kept unencoded for file upload
detection. Other values are properly URL-encoded.

### Fix 2: Use SplitN to limit split count

```go
array := strings.SplitN(item, "=", 2)  // Only split on first '='
```

### Fix 3: Add URL decoding for field values

```go
if v, err := gurl.Decode(fieldValue); err == nil {
    fieldValue = v
}
```

## Compatibility Analysis

| Scenario | Before | After | Compatible |
|----------|--------|-------|------------|
| Normal form POST (no file upload) | ✅ Works | ✅ Works | ✅ Yes |
| File upload + normal field values | ✅ Works | ✅ Works | ✅ Yes |
| File upload + field values containing `=` or `&` | ❌ Truncated | ✅
Works | ✅ Fixed |
| Field value is `@file:` (no path) | ✅ Works | ✅ Works | ✅ Yes |
| Field value starts with `@file:` but file doesn't exist | ❌ Error | ❌
Error | ✅ Yes |
| User sends pre-encoded value like `"aaa%3D1"` | ✅ Works | ✅ Works | ✅
Yes |
| Content-Type: application/json | ✅ Works | ✅ Works | ✅ Yes |
| Content-Type: application/xml | ✅ Works | ✅ Works | ✅ Yes |

### Breaking Change Assessment

**No breaking changes.** The fix only affects the file upload scenario
where field values contain special characters (`=`, `&`). Previously
this scenario was broken, now it works correctly.

### Edge Cases

1. **Literal `@file:` value**: GoFrame treats `@file:` as a special
marker for file upload. This is a framework design decision and remains
unchanged.

2. **URL decode failure**: If URL decoding fails (e.g., invalid `%XX`
sequence), the original value is preserved.

## Test Coverage

Added comprehensive tests covering:

- `Test_Issue4156` - Basic fix verification
- `Test_Issue4156_MultipleSpecialChars` - Multiple `=`, `&`, `%`, `+`,
spaces
- `Test_Issue4156_MultipleFields` - Multiple fields with special
characters
- `Test_Issue4156_NoFileUpload` - Normal POST without file upload
- `Test_Issue4156_PreEncodedValue` - Pre-encoded values like `%3D`
- `Test_Issue4156_EmptyAndSpecialValues` - Edge cases (`=` at start/end,
only special chars)
- `TestBuildParams_*` - httputil.BuildParams comprehensive tests

All tests pass, including existing `Test_Issue3748` which tests the
`@file:` marker handling.

## Files Changed

- `internal/httputil/httputils.go` - Remove global URL encoding disable,
adjust `@file:` condition
- `internal/httputil/httputils_test.go` - Add comprehensive BuildParams
tests
- `net/gclient/gclient_request.go` - Use SplitN, add URL decoding
- `net/gclient/gclient_z_unit_issue_test.go` - Add Issue 4156 test cases

+
+`gf gen tpl` 现在支持灵活的标签配置,可以选择性地为生成的结构体字段添加 `omitempty` 或其他自定义标签。
+
+## 配置选项一览
+
+| 选项 | 类型 | 默认值 | 说明 |
+|------|------|--------|------|
+| `jsonOmitempty` | bool | false | 为所有字段添加 omitempty |
+| `jsonOmitemptyAuto` | bool | false | 仅为可空字段自动添加 omitempty |
+| `withOrmTag` | bool | true | 是否添加 orm 标签 |
+| `descriptionTag` | bool | false | 是否添加 description 标签 |
+| `noJsonTag` | bool | false | 是否禁用 JSON 标签 |
+| `fieldMapping.tags` | map | - | 字段级自定义标签 |
+
+## 配置方式
+
+### 1. 全局开关 - `jsonOmitempty`
+
+为所有字段的 JSON 标签添加 `omitempty`:
+
+```yaml
+gfcli:
+  gen:
+    tpl:
+      jsonOmitempty: true
+```
+
+**生成结果:**
+```go
+type User struct {
+    ID       int    `json:"id,omitempty" orm:"id" description:"用户ID"`
+    Name     string `json:"name,omitempty" orm:"name" description:"用户名"`
+    Email    string `json:"email,omitempty" orm:"email" description:"邮箱"`
+}
+```
+
+---
+
+### 2. 智能判断 - `jsonOmitemptyAuto` (推荐)
+
+仅为可空字段自动添加 `omitempty`:
+
+```yaml
+gfcli:
+  gen:
+    tpl:
+      jsonOmitemptyAuto: true
+```
+
+**假设数据库表结构:**
+```sql
+CREATE TABLE user (
+    id INT NOT NULL,
+    name VARCHAR(50) NOT NULL,
+    email VARCHAR(100) NULL,  -- 可空字段
+    age INT NULL                -- 可空字段
+);
+```
+
+**生成结果:**
+```go
+type User struct {
+    ID    int    `json:"id" orm:"id" description:"用户ID"`
+    Name  string `json:"name" orm:"name" description:"用户名"`
+    Email string `json:"email,omitempty" orm:"email" description:"邮箱"`  // 自动添加
+    Age   int    `json:"age,omitempty" orm:"age" description:"年龄"`     // 自动添加
+}
+```
+
+---
+
+### 3. ORM 标签控制 - `withOrmTag`
+
+控制是否添加 orm 标签 (默认启用):
+
+```yaml
+gfcli:
+  gen:
+    tpl:
+      withOrmTag: false  # 不生成 orm 标签
+```
+
+**生成结果:**
+```go
+type User struct {
+    ID    int    `json:"id" description:"用户ID"`          // 没有 orm 标签
+    Name  string `json:"name" description:"用户名"`        // 没有 orm 标签
+    Email string `json:"email" description:"邮箱"`         // 没有 orm 标签
+}
+```
+
+---
+
+### 4. 字段级精确控制 - `fieldMapping`
+
+针对特定字段自定义标签 (优先级最高):
+
+```yaml
+gfcli:
+  gen:
+    tpl:
+      fieldMapping:
+        user.password:
+          type: string
+          tags:
+            json: "-"  # 不序列化
+
+        user.email:
+          type: string
+          tags:
+            json: "email,omitempty"
+            validate: "required,email"
+            binding: "required"
+
+        user.status:
+          type: int
+          tags:
+            json: "status,omitempty"
+            validate: "oneof=0 1 2"
+            example: "1"
+```
+
+**生成结果:**
+```go
+type User struct {
+    Password string `json:"-" orm:"password" description:"密码"`
+    Email    string `binding:"required" json:"email,omitempty" validate:"required,email" description:"邮箱"`
+    Status   int    `example:"1" json:"status,omitempty" validate:"oneof=0 1 2" description:"状态"`
+}
+```
+
+---
+
+## 常见标签示例
+
+### validate 标签 (gin validator)
+
+```yaml
+fieldMapping:
+  user.email:
+    tags:
+      validate: "required,email"
+
+  user.age:
+    tags:
+      validate: "gte=0,lte=150"
+
+  user.password:
+    tags:
+      validate: "required,min=8,max=32"
+```
+
+### binding 标签 (gin binding)
+
+```yaml
+fieldMapping:
+  user.name:
+    tags:
+      binding: "required"
+
+  user.email:
+    tags:
+      binding: "required,email"
+```
+
+### swagger 文档标签
+
+```yaml
+fieldMapping:
+  user.id:
+    tags:
+      example: "1"
+      description: "用户唯一标识"
+
+  user.status:
+    tags:
+      example: "1"
+      enums: "0,1,2"
+```
+
+### 多个自定义标签组合
+
+```yaml
+fieldMapping:
+  user.email:
+    type: string
+    tags:
+      json: "email,omitempty"
+      validate: "required,email"
+      binding: "required"
+      example: "user@example.com"
+      description: "用户邮箱地址"
+```
+
+---
+
+## 配置优先级
+
+标签配置的优先级从高到低:
+
+1. **fieldMapping.tags** - 字段级自定义标签 (优先级最高)
+2. **jsonOmitempty** - 全局 omitempty 开关
+3. **jsonOmitemptyAuto** - 智能判断可空字段
+4. **默认行为** - 不添加 omitempty
+
+---
+
+## 完整配置示例
+
+```yaml
+gfcli:
+  gen:
+    tpl:
+      link: "mysql:root:12345678@tcp(127.0.0.1:3306)/test"
+      path: "./output"
+      tplPath: "./templates"
+      jsonCase: "CamelLower"
+      importPrefix: "github.com/example/project"
+
+      # 全局配置
+      jsonOmitemptyAuto: true  # 可空字段自动添加 omitempty
+      withOrmTag: true         # 添加 orm 标签 (默认)
+      descriptionTag: true     # 添加 description 标签
+
+      # 类型映射
+      typeMapping:
+        decimal:
+          type: decimal.Decimal
+          import: github.com/shopspring/decimal
+
+      # 字段级配置
+      fieldMapping:
+        user.password:
+          type: string
+          tags:
+            json: "-"
+
+        user.email:
+          type: string
+          tags:
+            json: "email,omitempty"
+            validate: "required,email"
+            binding: "required"
+
+        order.total_amount:
+          type: decimal.Decimal
+          import: github.com/shopspring/decimal
+          tags:
+            json: "totalAmount,omitempty"
+            validate: "gt=0"
+```
+
+---
+
+## 命令行使用
+
+```bash
+# 使用配置文件
+gf gen tpl
+
+# 命令行参数
+gf gen tpl -tp ./templates -p ./output -ja -wo
+# -ja: jsonOmitemptyAuto
+# -wo: withOrmTag
+
+# 组合使用
+gf gen tpl -l "mysql:root:pass@tcp(127.0.0.1:3306)/db" -tp ./tpl -ja -c -wo
+```
+
+---
+
+## 模板中使用
+
+如果你需要在自定义模板中使用标签功能:
+
+```go
+// entity.tpl
+type {{.table.NameCaseCamel}} struct { {{range $i,$v := .table.Fields}}
+    {{$v.NameCaseCamel}} {{$v.LocalType}} {{$v.BuildTags $.tagInput}} // {{$v.Comment}}{{end}}
+}
+```
+
+或者分别使用单个标签方法:
+
+```go
+type {{.table.NameCaseCamel}} struct { {{range $i,$v := .table.Fields}}
+    {{$v.NameCaseCamel}} {{$v.LocalType}} `json:"{{$v.JsonTag $.tagInput.JsonOmitempty $.tagInput.JsonOmitemptyAuto}}" orm:"{{$v.OrmTag}}"` // {{$v.Comment}}{{end}}
+}
+```
+
+---
+
+## 注意事项
+
+1. **字段名格式**: `fieldMapping` 中的 key 格式为 `表名.字段名`,使用数据库中的实际字段名 (非驼峰)
+
+2. **标签顺序**: 自定义标签会按字母顺序排列,确保生成结果一致
+
+3. **特殊字符**: 如果标签值包含双引号,会自动转义
+
+4. **DO 文件**: DO 文件 (model/do) 只保留 description 标签,不包含 JSON/ORM 标签
+
+5. **兼容性**: 与现有的 `typeMapping` 和 `fieldMapping` 完全兼容
+
+6. **默认值**: `withOrmTag` 默认为 `true`,如果不需要 orm 标签,需要显式设置为 `false`
