# pdd.dll 使用教程
## 1.创建DLL工具实例
### 加载DLL文件
```gotemplate
// PddDLL 拼多多工具DLL结构
type pddDLL struct {
dll *syscall.DLL
pddGoodsOuterCatMappingGet *syscall.Proc // 类目预测
freeCString *syscall.Proc // 释放C字符串
}
// 初始化pddDLL
func InitPddDLL() (*pddDLL, error) {
dllPath := filepath.Join("dll", "pdd.dll")
if _, err := os.Stat(dllPath); os.IsNotExist(err) {
return nil, fmt.Errorf("pdd DLL 不存在: %s", dllPath)
}
if dll, err := syscall.LoadDLL(dllPath); err != nil {
return nil, fmt.Errorf("加载pdd DLL 失败: %s", err)
} else {
return &pddDLL{
dll: dll,
pddGoodsOuterCatMappingGet: dll.MustFindProc("PddGoodsOuterCatMappingGet"),
freeCString: dll.MustFindProc("FreeCString"),
}, nil
}
}
dll, err := InitPddDLL()
```
### 获取C字符串
```gotemplate
// cStr 获取C字符串
func (m *pddDLL) cStr(p uintptr) string {
if p == 0 {
return ""
}
b := []byte{}
for i := uintptr(0); ; i++ {
c := *(*byte)(unsafe.Pointer(p + i))
if c == 0 {
break
}
b = append(b, c)
}
s := string(b)
if m.freeCString != nil {
m.freeCString.Call(p)
}
return s
}
```
## 2. 使用dll函数示例
```gotemplate
// 类目预测
func (m *pddDLL) PddGoodsOuterCatMappingGet(clientId, clientSecret, accessToken,
outerCatId, outerCatName, outerGoodsName string) (string, error) {
proc, err := m.dll.FindProc("PddGoodsOuterCatMappingGet")
if err != nil {
return "", fmt.Errorf("找不到函数 PddGoodsOuterCatMappingGet: %v", err)
}
clientIdPtr, _ := syscall.BytePtrFromString(clientId)
clientSecretPtr, _ := syscall.BytePtrFromString(clientSecret)
accessTokenPtr, _ := syscall.BytePtrFromString(accessToken)
outerCatIdPtr, _ := syscall.BytePtrFromString(outerCatId)
outerCatNamePtr, _ := syscall.BytePtrFromString(outerCatName)
outerGoodsNamePtr, _ := syscall.BytePtrFromString(outerGoodsName)
resultPtr, _, _ := proc.Call(
uintptr(unsafe.Pointer(clientIdPtr)),
uintptr(unsafe.Pointer(clientSecretPtr)),
uintptr(unsafe.Pointer(accessTokenPtr)),
uintptr(unsafe.Pointer(outerCatIdPtr)),
uintptr(unsafe.Pointer(outerCatNamePtr)),
uintptr(unsafe.Pointer(outerGoodsNamePtr)),
)
result := m.cStr(resultPtr)
return result, nil
}
```
