WinForm窗体创建的调用api的类
/// <summary>
/// 调用api返回json
/// </summary>
/// <param name="url">api地址</param>
/// <param name="jsonstr">接收参数</param>
/// <param name="type">类型</param>
/// <returns></returns>
public static string HttpPost(string url, string jsonstr)//,string type
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); //--需要封装的参数
request.CookieContainer = new CookieContainer();
//以下是发送的http头
request.Referer = "";
//request.ContentType = "text/xml";
request.Headers["Accept-Language"] = "zh-CN,zh;q=0.";
request.Headers["Accept-Charset"] = "GBK,utf-8;q=0.7,*;q=0.3";
request.UserAgent = "User-Agent:Mozilla/5.0 (Windows NT 5.1) AppleWebKit/535.1 (Khtml, like Gecko) Chrome/14.0.835.202 Safari/535.1";
request.KeepAlive = true;
//上面的http头看情况而定，但是下面俩必须加
request.ContentType = "application/x-www-form-urlencoded";
Encoding encoding = Encoding.UTF8;//根据网站的编码自定义
request.Method = "get"; //--需要将get改为post才可行
string postDataStr;
//Stream requestStream = request.GetRequestStream();
if (jsonstr != "")
postDataStr = jsonstr;//--需要封装,形式如“arg=arg1&arg2=arg2”
byte[] postData = encoding.GetBytes(postDataStr);//postDataStr即为发送的数据，
//request.ContentLength = postData.Length; //写入后不允许设置此属性
//requestStream.Write(postData, 0, postData.Length);
HttpWebResponse response = (HttpWebResponse)request.GetResponse(); //远程服务器返回错误: (405) 不允许的方法/远程服务器返回错误: (500) 内部服务器错误。
Stream responseStream = response.GetResponseStream();
StreamReader streamReader = new StreamReader(responseStream, encoding);
string retString = streamReader.ReadToEnd();
streamReader.Close();
responseStream.Close();
return retString;
API程序
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
namespace webApi_test2.Models
//方法接口
public interface IUsersRepository
Task<Users> GetUser(string id);
Task<int> DeleteUser(string ID);
Task<int> AddAUsers(Users item);
Task<int> UpdateUsers(Users item);
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
namespace webApi_test2.Models
//实体类
public class Users
public string UserID get; set;
public string Pwd get; set;
public string UserName get; set;
public string Remark get; set;
public DateTime CreatedOn get; set;
public DateTime LastLoginTime get; set;
using Ivony.Data;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
namespace webApi_test2.Models
//接口的实现 （接口的实现方法根据框架的结构自行修改）
public class UsersRepository : IUsersRepository
//查询
public async Task<Users> GetUser(string id)
using (Db.UseDatabase("default"))
var x = Db.T($"select * from Users where UserID=id").ExecuteEntityAsync<Users>();
return await x;
//删除
public async Task<int> DeleteUser(string ID)
using (Db.UseDatabase("default"))
return await Db.T($"delete from Users where UserID=ID").ExecuteNonQueryAsync();
//添加
public async Task<int> AddAUsers(Users UsersItem)
using (Db.UseDatabase("default"))
return await Db.T($"insert into Users(UserID,Pwd,UserName,CreatedOn) values(UsersItem.UserID,UsersItem.Pwd,UsersItem.UserName,UsersItem.CreatedOn)").ExecuteNonQueryAsync();
//修改
public async Task<int> UpdateUsers(Users UserItem)
using (Db.UseDatabase("default"))
return await Db.T($"update Users set Pwd=UserItem.Pwd,UserName=UserItem.UserName,CreatedOn=UserItem.CreatedOn where UserID=UserItem.UserID").ExecuteNonQueryAsync();
创建Api控制器
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http;
using System.Threading.Tasks;
using Ivony.Data;
using Microsoft.AspNetCore.Mvc;
using webApi_test2.Models;
namespace webApi_test2.Controllers
[Route("api/[controller]")]
[ApiController]
public class ValuesController : ControllerBase
//接口的依赖注入根据自己框架的要求进行注入 本框架使用自己的源，与其他稍有不同
private IUsersRepository _Repository get; set;
public ValuesController(IUsersRepository Repository)
_Repository = Repository;
//GET api/values
[HttpGet]
public ActionResult<IEnumerable<string>> Get()
return new string[] "value1", "value2" ;
// GET api/values/5
[HttpGet("id")]
public ActionResult<string> Get(int id)
return "value";
// POST api/values
[HttpPost]
public void Post([FromBody] string value)
// PUT api/values/5
[HttpPut("id")]
public void Put(int id, [FromBody] string value)
//删除
// DELETE api/values/5
[HttpGet("Delete")]
public int Delete(string id)
try
//UsersRepository ur = new UsersRepository();
//var x = ur.DeleteUser(id);
var x = _Repository.DeleteUser(id);
return x.Result;
catch(Exception ex)
throw;
//修改
[HttpGet("UpdateUsers")]
public async Task<int> UpdateUsers(string UserID, string UserName, string Pwd, string CreatedOn)/*Users UserItem*/
Users UserItem = new Users();
try
//初始化赋值
UserItem.UserID = UserID;
UserItem.Pwd = Pwd;
UserItem.UserName = UserName;
UserItem.CreatedOn = Convert.ToDateTime(CreatedOn);
//UsersRepository ur = new UsersRepository();
//var x = ur.UpdateUsers(UserItem);
var x = _Repository.UpdateUsers(UserItem);
return await x;
catch (Exception)
throw;
//查询 根据UserID查询
[HttpGet("GetUser")]
public async Task<Users> GetUser(string UserID)
try
//UsersRepository ur = new UsersRepository();
//var x = ur.GetUser(UserID);
var x = _Repository.GetUser(UserID);
return await x;
//return await _Repository.GetUser(UserID);
catch (Exception)
throw;
//添加
//GET:/api/values/Get
[HttpGet("AddUsers")]
public async Task<int> AddUsers(string UserID, string UserName, string Pwd, string CreatedOn)/*Users Item*/
Users UserItem = new Users();
try
UserItem.UserID = UserID;
UserItem.Pwd = Pwd;
UserItem.UserName = UserName;
UserItem.CreatedOn = Convert.ToDateTime(CreatedOn);
//UsersRepository ur = new UsersRepository();
//var x = ur.AddAUsers(UserItem);
var x = _Repository.AddAUsers(UserItem);
return await x;
catch (Exception)
throw;
依赖注入需要的类
using Microsoft.Extensions.DependencyInjection;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Nebula.Hosting;
using webApi_test2.Models;
[assembly: HostInitialize(typeof(webApi_test2.Models.ServiceInitialize))]//webApi_test2.Models.ServiceInitialize 文件位置
namespace webApi_test2.Models
internal class ServiceInitialize
public static void Initialize(IServiceCollection services)
services.AddSingleton<IUsersRepository, UsersRepository>();
