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);  }
