Example (Http) ¶
示例：如何在HTTP处理程序中使用
// 这是一个示例HTTP处理程序
/*
func RegisterHandler(w http.ResponseWriter, r *http.Request) {
var user User
// 解析请求JSON数据到结构体
if err := json.NewDecoder(r.Body).Decode(&user); err != nil {
http.Error(w, "无效的请求数据", http.StatusBadRequest)
return
}
// 验证用户数据
v := validation.NewValidator()
validation.ValidateStruct(v, &user)
if !v.Valid() {
// 返回验证错误
w.Header().Set("Content-Type", "application/json")
w.WriteHeader(http.StatusBadRequest)
// 构建错误响应
errorResponse := make(map[string]string)
for _, err := range v.Errors {
errorResponse[err.Field] = err.Message
}
json.NewEncoder(w).Encode(map[string]any{
"errors": errorResponse,
})
return
}
// 继续处理有效请求...
}
*/
