JavaScript定义函数,创建函数实例时的内部原理

  • 框架:asp.net core webapi
  • asp.net core webapi接收参数,请求变量设置

目录

接收multipart/form-data、application/x-www-form-urlencoded类型参数

Post ([FromForm]TokenRequestInput user)
可以接收发送类型为multipart/form-data、application/x-www-form-urlencoded的数据

  [HttpPost]
  public async Task<IActionResult> ChangePhoneNum([FromForm] TokenRequestInput user)
  {     
      return Ok(11222);
  }

  /// <summary>
  /// 用户信息
  /// </summary>
  public class TokenRequestInput
  {
      /// <summary>
      /// 微信 用户的openid
      /// </summary>
      public string? openid { get; set; }

      /// <summary>
      /// 微信头像图片,base64字符串
      /// </summary>
      public string? head_img_base64 { get; set; }

      /// <summary>
      /// 微信昵称
      /// </summary>
      public string? nichen { get; set; }

       
  }

接收URL参数

请求地址
http://localhost:5170/api/User/GetToken?code=22222

 [HttpGet]
 public async Task<IActionResult> GetToken(string code)
 {
     var result = await wxAppletLoginBll.GetLoginToken(code);
     return Ok(result);
 }

接收上传的文件

IFormFile file这个参数是接收文件,mimeType=multipart/form-data
参数userId,通过url参数传入

/// <summary>
/// 接收上传的文件
/// </summary>
/// <param name="file">文件二进制</param>
/// <param name="userId">url参数</param>
/// <returns></returns>
[HttpPost]
public async Task<IActionResult> GetAdd(IFormFile file, string userId)
{ 
    return Ok("ok");
}

webapi接收json参数

发送json参数

{
  "openid": "string",
  "head_img_base64": "string",
  "nichen": "string"
}
  [HttpPost]
  public async Task<IActionResult> AddUser(TokenRequestInput user)
  {    
      return Ok(3344);
  }

完整控制器,启动类参考

using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using WebProjectNet7.DataBaseEntity.Entity;
using WebProjectNet7.IBLL;
using WebProjectNet7.ViewEntity;

namespace Api_BigData.Controllers
{
    /// <summary>
    /// 预警
    /// </summary>
    [Route("api/[controller]/[action]")]
    [MyRequestFilter]
    [ApiController]
    public class WarningController : ControllerBase
    {
        readonly IWaringLogBll waringLogBll = AppServicesHelpter.GetServices<IWaringLogBll>();


        /// <summary>
        /// 设置预警记录,已经读了
        /// </summary>
        /// <param name="logId">预警id</param>
        /// <returns></returns>
        [HttpGet]
        public async Task<IActionResult> SetReadedAsync(long logId)
        {
            var data = await waringLogBll.SetReadedAsync(logId);
            return Ok(data);
        }
	}
}

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.

//依赖注入

 Configure the HTTP request pipeline.

app.UseSwagger();

        await next();
    }
});
