目录
接收multipart/form-data、application/x-www-form-urlencoded类型参数接收URL参数接收上传的文件webapi接收json参数完整控制器，启动类参考Program.cs
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>code>
/// <param name="userId">url参数</param>code>
/// <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

[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>code>
/// <returns></returns>
[HttpGet]
public async Task<IActionResult> SetReadedAsync(long logId)
{
var data = await waringLogBll.SetReadedAsync(logId);
return Ok(data);
}
}
