WebApiClient的接口输入验证方法_实用技巧_

 public class UserInfo { [Required] [StringLength(10, MinimumLength = 1)] public string Account { get; set; } [Required] [StringLength(10, MinimumLength = 6)] public string Password { get; set; } } 

 /// 
 /// 提供参数值和参数的属性值输入合法性验证 /// 
 static class ParameterValidator { /// 
 /// 类型的属性否需要验证缓存 /// 
 private static readonly ConcurrentCache cache = new ConcurrentCache(); /// 
 /// 返回是否需要进行属性验证 /// 
 /// 实例 ///  private static bool IsNeedValidateProperty(object instance) { if (instance == null) { return false; } var type = instance.GetType(); if (type == typeof(string) || type.GetTypeInfo().IsValueType == true) { return false; } return cache.GetOrAdd(type, t => t.GetProperties().Any(p => p.CanRead && p.IsDefined(typeof(ValidationAttribute), true))); } /// 
 /// 验证参数值输入合法性 /// 验证参数的属性值输入合法性 /// 
 /// 参数描述 /// 是否验证属性值 ///  public static void Validate(ApiParameterDescriptor parameter, bool validateProperty) { var name = parameter.Name; var instance = parameter.Value; foreach (var validation in parameter.ValidationAttributes) { validation.Validate(instance, name); } if (validateProperty == true && IsNeedValidateProperty(instance) == true) { var ctx = new ValidationContext(instance) { MemberName = name }; Validator.ValidateObject(instance, ctx, true); } } } 

 // /GET webapi/user/GetById?id=id001 // Return HttpResponseMessage [HttpGet("webapi/user/GetById/{id}")] [BasicAuth("userName", "password")] ITask GetByIdAsync( [Required, StringLength(10)] string id); 

 public class UserInfo { [Required] [StringLength(10, MinimumLength = 1)] public string Account { get; set; } [Required] [StringLength(10, MinimumLength = 6)] public string Password { get; set; } } // POST webapi/user/UpdateWithJson // Body {"Account":"laojiu","Password":"123456"} // Return json或xml内容 [HttpPost("webapi/user/UpdateWithJson")] ITask UpdateWithJsonAsync( [JsonContent("yyyy-MM-dd HH:mm:ss")] UserInfo user);

 var config = new HttpApiConfig { UseParameterPropertyValidate = false }; var client = HttpApiClient.Create(config);
