使用ASP.NET Core开发信息采集系统将用户数据添加至企业微信

2023-11-08 11:31:04

一、启动Visual Studio 2019，创建ASP.NET Core Web应用程序

二、在Models文件夹添加新项 Person.cs

using System.ComponentModel.DataAnnotations;
using Microsoft.AspNetCore.Mvc;

namespace 信息采集系统.Models
{
    public class Person
    {
        [Display(Name = "编号")]
        public int ID { get; set; }
        [Display(Name = "姓名")]
        [Required(ErrorMessage = "必须输入姓名")]
        [Remote("CheckName", "MyValidation")]
        public string Name { get; set; }
        [Display(Name = "性别")]
        public Gender Gender { get; set; }
        [Display(Name = "手机号")]
        [Required(ErrorMessage = "必须输入手机号码")]
        [StringLength(11, ErrorMessage = "手机号码长度应为11位", MinimumLength = 11)]
        public string Mobile { get; set; }
        [Remote("CheckFatherName", "MyValidation")]
        public string FatherName { get; set; }
        [Remote("CheckMotherName", "MyValidation")]
        public string MotherName { get; set; }
        [Display(Name = "邀请码")]
        [Required(ErrorMessage = "必须输入认证码")]
        [Remote("CheckInvitationCode", "MyValidation")]
        public string InvitationCode { get; set; }
    }
    public enum Gender
    {
        [Display(Name = "男")]
        Male = 1,
        [Display(Name = "女")]
        Female = 2
    }
}

三、在Controllers文件夹，添加“新搭建基架的项目”

点击数据上下文右侧的加号按钮，新建一个数据上下文类

修改StartUp.cs

        public void ConfigureServices(IServiceCollection services)
        {
            services.Configure<CookiePolicyOptions>(options =>
            {
                // This lambda determines whether user consent for non-essential cookies is needed for a given request.
                options.CheckConsentNeeded = context => true;
                options.MinimumSameSitePolicy = SameSiteMode.None;
            });


            services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);

            services.AddDbContext<PersonContext>(options =>
                    options.UseSqlServer(PersonContext.ConnectionString));
        }

修改PersonContext.cs

using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.EntityFrameworkCore;

namespace 信息采集系统.Models
{
    public class PersonContext : DbContext
    {
        public static string ConnectionString
        {
            get
            {
                var path = AppDomain.CurrentDomain.BaseDirectory;
                var DatabasePath = System.IO.Path.Combine(new string[] { path, "Person.mdf" });
                var s = $"Data Source=(LocalDB)\\MSSQLLocalDB;Initial Catalog=Person;AttachDbFilename={DatabasePath};";
                return s;
            }
        }

        public PersonContext (DbContextOptions<PersonContext> options)
            : base(options)
        {
        }

        public DbSet<信息采集系统.Models.Person> Person { get; set; }
    }
}

四、添加控制器MyValidationController.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;

namespace 信息采集系统.Controllers
{
    public class MyValidationController : Controller
    {
        private Models.PersonContext _context { get; set; }
        public MyValidationController(Models.PersonContext context)
        {
            this._context = context;
        }
        public JsonResult CheckName(string Name)
        {
            var chinese= Common.PinyinHelper.IsChineseString(Name);
            if (chinese)
            {
                return Json(true);
            }
            else
            {
                return Json("姓名必须输入中文");
            }
        }
        public JsonResult CheckFatherName(string FatherName)
        {
            var chinese = Common.PinyinHelper.IsChineseString(FatherName);
            if (chinese)
            {
                return Json(true);
            }
            else
            {
                return Json("姓名必须输入中文");
            }
        }

        public JsonResult CheckMotherName(string MotherName)
        {
            var chinese = Common.PinyinHelper.IsChineseString(MotherName);
            if (chinese)
            {
                return Json(true);
            }
            else
            {
                return Json("姓名必须输入中文");
            }
        }
        public JsonResult CheckInvitationCode(string InvitationCode)
        {
            var b = Common.InvitationCode.IsValid(InvitationCode);
            if (b)
            {
                var item = _context.Person.FirstOrDefault(x => x.InvitationCode == InvitationCode);
                if (item == null)
                {
                    return Json(true);
                }
                else
                {
                    return Json($"此邀请码已被使用，使用人：{item.Name}");
                }
            }
            else
            {
                return Json("错误的邀请码");
            }
        }
    }
}

五、添加控制器Database.cs，用于创建数据库和删除数据库。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;

namespace 信息采集系统.Controllers
{
    public class DatabaseController : Controller
    {
        private Models.PersonContext _context { get; set; }
        public DatabaseController(Models.PersonContext context)
        {
            this._context = context;
        }
        public string Create()
        {
            var isCreated = _context.Database.EnsureCreated();
            return $"Create={isCreated}";
        }
        public string Delete()
        {
            var IsDeleted = _context.Database.EnsureDeleted();
            return $"Create={IsDeleted}";

        }
    }
}

六、修改Views/Person/Create.cshtml，解决性别枚举类型无法列出枚举值的问题。

                <select asp-for="Gender" asp-items="@Html.GetEnumSelectList(typeof(Gender))" class="form-control"></select>

七、修改StartUp.cs，增加配置文件读取

        public static IConfiguration Config { get; set; }
        public static string CorpId { get { return Config.GetSection("CorpId").Value; } }
        public static string CorpSecret { get { return Config.GetSection("CorpSecret").Value; } }
        public static long DefaultDepartment { get { return int.Parse(Config.GetSection("DefaultDepartment").Value); } }

        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
            Config = configuration;
        }

八、添加微信操作类AccessToken.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Json;
using System.IO;
using System.Text;

namespace 信息采集系统.Common
{
    public class AccessToken : JsonObject<AccessToken>
    {
        [DataMember] public int errcode { get; set; }
        [DataMember] public string errmsg { get; set; }
        [DataMember] public string access_token { get; set; }
        [DataMember] public int expires_in { get; set; }
        public static AccessToken Update()
        {
            var CorpId = Startup.CorpId;
            var Secret = Startup.CorpSecret;
            var url = $"https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid={CorpId}&corpsecret={Secret}";
            var b = WebHelper.HttpGet(url);
            var item = AccessToken.From(b);
            return item;
        }
    }
}

添加微信操作类QiYeWeiXinUser.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Json;
using System.IO;
using System.Text;

namespace 信息采集系统.Common
{
    public class QiYeWeiXinUser
    {
        [DataContract]
        private class GetUserInfo : JsonObject<GetUserInfo>
        {
            [DataMember] public long errcode { get; set; }
            [DataMember] public string errmsg { get; set; }
            [DataMember] public string userid { get; set; }
            [DataMember] public string name { get; set; }
            [DataMember] public long[] department { get; set; }
            [DataMember] public string mobile { get; set; }
            [DataMember] public string gender { get; set; }
            [DataMember]public UserExtAttr extattr { get; set; }
        }
        [DataContract]
        private class AddUserRequest : JsonObject<AddUserRequest>
        {
            [DataMember] public string userid { get; set; }
            [DataMember] public string name { get; set; }
            [DataMember] public long[] department { get; set; }
            [DataMember] public string mobile { get; set; }
            [DataMember] public string gender { get; set; }
            [DataMember]public UserExtAttr extattr { get; set; }
        }
        [DataContract]
        public class AddUserResponse : JsonObject<AddUserResponse>
        {
            [DataMember] public long errcode { get; set; }
            [DataMember] public string errmsg { get; set; }

        }
        [DataContract]
        public class UserExtAttr
        {
            [DataMember]public List<UserAttr> attrs { get; set; }
        }
        [DataContract]
        public class UserAttr
        {
            [DataMember]public long type { get; set; }
            [DataMember]public string name { get; set; }
            [DataMember]public AttrText text { get; set; }
        }
        [DataContract]
        public class AttrText
        {
            [DataMember]public string value { get; set; }
        }

        public static bool Exist(string access_token, string userid)
        {
            var url = $"https://qyapi.weixin.qq.com/cgi-bin/user/get?access_token={access_token}&userid={userid}";
            var web = System.Net.WebRequest.Create(url);
            using (var responseStream = web.GetResponse().GetResponseStream())
            {
                var sr = new System.IO.StreamReader(responseStream);
                var s = sr.ReadToEnd();
                var b = System.Text.Encoding.UTF8.GetBytes(s);
                var item = GetUserInfo.From(b);
                if (item == null)
                {
                    return false;
                }
                else
                {
                    if (item.userid != userid)
                    {
                        return false;
                    }
                    else
                    {
                        return true;
                    }
                }
            }

        }

        public static bool Add(string accesstoken, string userid, string name, string mobile, string gender, long[] department,string fatherName,string motherName, out string errmsg)
        {
            var user = new AddUserRequest()
            {
                userid = userid,
                name = name,
                mobile = mobile,
                gender = gender,
                department = department,
                extattr = new UserExtAttr()
                {
                    attrs = new List<UserAttr>()
                    {
                        new UserAttr()
                        {
                            type = 0,
                            name = "父亲",
                            text = new AttrText() { value = fatherName }
                        },
                        new UserAttr()
                        {
                            type = 0,
                            name = "母亲",
                            text = new AttrText() { value = motherName }
                        }
                    }
                }
            };

            var b = user.ToArray();
            var url = $"https://qyapi.weixin.qq.com/cgi-bin/user/create?access_token={accesstoken}";
            var rb = WebHelper.HttpPost(url, b);
            var response = AddUserResponse.From(rb);
            if (response.errcode == 0)
            {
                errmsg = "";
                return true;
            }
            else
            {
                errmsg = response.errmsg;
                return false;
            }
        }
    }
}

九、修改PersonController.cs

        public async Task<IActionResult> Create([Bind("ID,FullName,Gender,Mobile,InvitationCode")] Student student)
        {
            if (ModelState.IsValid)
            {
                #region 添加到企业微信
                var pinyin = PinyinHelper.GetPinyin(student.FullName);
                var token = AccessToken.Update();
                var index = 0;
                var userid = "";
                var exist = true;
                while (exist)
                {
                    if (index == 0)
                    {
                        userid = pinyin;
                    }
                    else
                    {
                        userid = $"{pinyin}{index}";
                    }
                    exist = QiYeWeiXinUser.Exist(token.access_token, userid);
                }
                string errmsg;
                var success = QiYeWeiXinUser.Add(token.access_token, userid, student.FullName, student.Mobile, student.Gender.ToString(), new long[] { Startup.DefaultDepartment },out errmsg);

                Console.WriteLine($"add user:{student.FullName}\t{userid}");
                #endregion

                if (success)
                {
                    _context.Add(student);
                    await _context.SaveChangesAsync();
                    //return RedirectToAction(nameof(Index));
                    return RedirectToAction(nameof(QRCode));
                }
                else
                {
                    return RedirectToAction(nameof(Error), new { errmsg });
                }
            }
            return View(student);
        }

10、修改appsettings.json，增加以下内容

  "CorpId": "wx8da1???????06720",
  "CorpSecret": "sc_LkWSzfKq2Y3x2??????????gMPlVtU5Ecx0zs",
  "DefaultDepartment": "3",
