获取Token

通过企业ID及管理员组I的获取Token

 string strulr = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid={0}&corpsecret={1}";

            string corpID = "wx企业ID"; //企业ID
            string Secret = "管理员组ID";//管理员组ID

            HttpHelper http = new HttpHelper();

            string respone = http.Get(string.Format(strulr, corpID, Secret), Encoding.UTF8);

            var token = JsonConvert.DeserializeObject<Token>(respone);

            Token._Token = token;

            return token;

 返回的Token为

{"access_token":"NttjomfbHraVFAQTYg1NJ4fcP2dbJpnlnUH0TXT27MxxxxxxxxxxxxxxA","expires_in":7200}

 expires_in为Token的有效时长，Token再调用接口时自动续期。

经过封装后的Token类

 public class Token
    {
        public static Token _Token;

        public string access_token { get; set; }

        public int expires_in { get; set; }

        private DateTime createTokenTime = DateTime.Now;

        /// <summary>
        /// 到期时间(防止时间差，提前1分钟到期)
        /// </summary>
        /// <returns></returns>
        public DateTime TookenOverdueTime
        {
            get { return createTokenTime.AddSeconds(expires_in - 60); }
        }

        /// <summary>
        /// 刷新Token
        /// </summary>
        public static void Renovate()
        {
            if (_Token == null)
            {
                GetNewToken();
            }

            Token._Token.createTokenTime = DateTime.Now;
        }

        public static bool IsTimeOut()
        {
            if (_Token == null)
            {
                GetNewToken();
            }

            return DateTime.Now >= Token._Token.TookenOverdueTime;
        }

        public static Token GetNewToken()
        {
            string strulr = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid={0}&corpsecret={1}";

            string corpID = "wx362a967b"; //企业ID
            string Secret = "e1OskLgJAScVSiFfWVK-0FfVz6svRVdEbR";//管理员组ID

            HttpHelper http = new HttpHelper();

            string respone = http.Get(string.Format(strulr, corpID, Secret), Encoding.UTF8);

            var token = JsonConvert.DeserializeObject<Token>(respone);

            Token._Token = token;

            return token;
        }

        public static string GetToken()
        {
            if (_Token == null)
            {
                GetNewToken();
            }
            return _Token.access_token;
        }
    }

IHttpSend接口声明，抽象出同一交互接口

    public interface IHttpSend
    {
        string Send(string url, string data);
    }

代码中Http请求分为4中：普通Get请求，普通Post请求，Post文件上传请求，Get文件下载请求

并且不同请求中，Send方法第二个参数Data包含内容不同

//普通Get请求
public class HttpGetRequest : IHttpSend
    {
        public string Send(string url, string data)
        {
            return new HttpHelper().Get(url, Encoding.UTF8);
        }
    }


//普通Post请求
public class HttpPostRequest : IHttpSend
    {
        public string Send(string url, string data)
        {
            return new HttpHelper().Post(url, data, Encoding.UTF8, Encoding.UTF8);
        }
    }

//Post文件上传请求
    class HttpPostFileRequest : IHttpSend
    {
        public string Send(string url, string data)
        {
            return new HttpHelper().PostFile(url, data,Encoding.UTF8);
        }
    }

//Get文件下载请求
 class HttpGetFileRequest : IHttpSend
    {
        public string Send(string url, string path)
        {
            Dictionary<string, string> header;

            var bytes = new HttpHelper().GetFile(url, out header);

            if (header["Content-Type"].Contains("application/json"))
            {
                return Encoding.UTF8.GetString(bytes);
            }
            else
            {
                Regex regImg = new Regex(""(?<fileName>.*)"", RegexOptions.IgnoreCase);

                MatchCollection matches = regImg.Matches(header["Content-disposition"]);

                string fileName = matches[0].Groups["fileName"].Value;

                string filepath = path.TrimEnd('\') + "\" + fileName;

                System.IO.Stream so = new System.IO.FileStream(filepath, System.IO.FileMode.Create);

                so.Write(bytes, 0, bytes.Length);

                so.Close();
            }

            return JsonConvert.SerializeObject(header);
        }
    }

与微信交互

构建微信返回结果基类

    public class OperationResultsBase
    {
        public int errcode { get; set; }
        public string errmsg { get; set; }
    }

  

构建统一发送接口，并使用协变，方便构造统一队列

    public interface ISend<out T>
        where T : OperationResultsBase, new()
    {
        T Send();
    }

  

构建微信发送基类

 public abstract class OperationRequestBase<T, THttp> : ISend<T>
        where T : OperationResultsBase, new()
        where THttp : IHttpSend, new()
    {
        protected abstract string Url();

        /// <summary>
        /// 视同attribute进行简单校验
        /// </summary>
        /// <param name="message"></param>
        /// <returns></returns>
        private bool Verify(out string message)
        {
            message = "";
            foreach (var pro in this.GetType().GetProperties())
            {
                var v = pro.GetCustomAttributes(typeof(IVerifyAttribute), true);


                foreach (IVerifyAttribute verify in pro.GetCustomAttributes(typeof(IVerifyAttribute), true))
                {
                    if (!verify.Verify(pro.PropertyType, pro.GetValue(this), out message))
                    {
                        return false;
                    }
                }
            }

            return true;
        }

        /// <summary>
        /// 格式化URL，替换Token
        /// </summary>
        /// <returns></returns>
        protected string GetUrl()
        {
            if (Token.IsTimeOut())
            {
                Token.GetNewToken();
            }

            string url = Url();

            if (url.Contains("=ACCESS_TOKEN"))
            {
                url = url.Replace("=ACCESS_TOKEN", "=" + Token.GetToken());
            }

            return url;
        }

        /// <summary>
        /// 发送
        /// </summary>
        /// <returns></returns>
        public T Send()
        {
            string message = "";
            if (!Verify(out message))
            {
                throw new Exception(message);
            }
            
            //string result = new HttpHelper().Post(url, JsonConvert.SerializeObject(this), Encoding.UTF8, Encoding.UTF8);

            IHttpSend httpSend = new THttp();

            string result = HttpSend(httpSend, GetUrl());

            return GetDeserializeObject(result);
        }

        /// <summary>
        /// 处理返回结果
        /// </summary>
        /// <param name="result"></param>
        /// <returns></returns>
        protected virtual T GetDeserializeObject(string result)
        {
            return JsonConvert.DeserializeObject<T>(result);
        }

        /// <summary>
        /// 处理发送请求
        /// </summary>
        /// <param name="httpSend"></param>
        /// <param name="url"></param>
        /// <returns></returns>
        protected virtual string HttpSend(IHttpSend httpSend, string url)
        {
            return httpSend.Send(url, JsonConvert.SerializeObject(this));
        }

    }

基类构造好，后续大部分开发就非常简单了，

需要先构建结果类（如果无特殊字段，可直接使用OperationResultsBase）

构建请求类，继承OperationRequestBase<>类，选择结果类，及发送方式，再构造URL，最后填入所需字段即可

如：开发“部门列表数据"接口

//先构造返回类
    public class DepartmentListResult :OperationResultsBase
    {
        /// <summary>
        /// 部门列表数据。以部门的order字段从小到大排列
        /// </summary>
        /// <returns></returns>
        public List<DepartmentItem> department { get; set; }


        public class DepartmentItem
        {
            /// <summary>
            /// 部门id
            /// </summary>
            /// <returns></returns>
            public string id { get; set; }

            /// <summary>
            /// 部门名称
            /// </summary>
            /// <returns></returns>
            public string name { get; set; }

            /// <summary>
            /// 父亲部门id。根部门为1
            /// </summary>
            /// <returns></returns>
            public string parentid { get; set; }
        } 
    }



//再构造请求类
    public class DepartmentList : OperationRequestBase<DepartmentListResult,HttpPostRequest>
    {
        protected override string Url()
        {
            return "https://qyapi.weixin.qq.com/cgi-bin/department/list?access_token=ACCESS_TOKEN";
        }
    }

如：开发“创建部门"接口

//返回值类
无


//请求类
/// <summary>
    /// 创建部门
    /// </summary>
    public class DepartmentCreate : OperationRequestBase<OperationResultsBase,HttpPostRequest>
    {
        protected override string Url()
        {
            return "https://qyapi.weixin.qq.com/cgi-bin/department/create?access_token=ACCESS_TOKEN";
        }

        /// <summary>
        /// 部门名称。长度限制为1~64个字符
        /// </summary>
        /// <returns></returns>
        [Length(1,64)]
        [IsNotNull]
        public string name { get; set; }

        /// <summary>
        /// 父亲部门id。根部门id为1
        /// </summary>
        /// <returns></returns>
        [IsNotNull]
        public string parentid { get; set; }

        /// <summary>
        /// 在父部门中的次序。从1开始，数字越大排序越靠后
        /// </summary>
        /// <returns></returns>
        public string order { get; set; }
    }

 验证

最后在加入加单验证机制，如不为空验证，长度限制

public interface IVerifyAttribute
    {
        bool Verify(Type type, object obj,out string message);
    }



 public class IsNotNullAttribute : Attribute, IVerifyAttribute
    {
        bool IsNotNull { get; set; }

        string Message { get; set; }

        public IsNotNullAttribute()
        {
            IsNotNull = true;
            Message = "不能为空";
        }

        public IsNotNullAttribute(bool isNotNull)
        {
            IsNotNull = isNotNull;
            Message = "不能为空";
        }
        public IsNotNullAttribute(bool isNull, string message)
        {
            IsNotNull = isNull;
            Message = message;
        }

        public bool Verify(Type type, object obj, out string message)
        {
            message = "";

            if (IsNotNull == false)
            {
                return true;
            }

            if (obj == null)
