Request 对象直接读取提交的表单数据。在项目中我们直接使用如下创建一个默认的预先配置好的WebApplication对象。
WebApplication.Create();var builder = WebApplication.CreateBuilder(args);// configure servicesvar app = builder.Build();// configure middlewareapp.Run();
相信上面这段代码大家看起来更熟悉
var app = WebApplication.Create();app.MapGet("", async context =>{context.Response.Headers.Append("content-type", "text/html;charset=utf-8");var page = $@"<!DOCTYPE html><html lang=""en""><head><meta charset=""UTF-8""><meta name=""viewport"" content=""width=device-width, initial-scale=1.0""><title>提交个人信息</title><style>body {{font-family: Arial, sans-serif;background-color: #f4f4f4;margin: 0;padding: 0;}}.container {{width: 50%;margin: 50px auto;background-color: #fff;padding: 20px;box-shadow: 0 0 10px rgba(0, 0, 0, 0.1);border-radius: 8px;}}h1 {{text-align: center;color: #333;}}form {{display: flex;flex-direction: column;}}input[type=""text""], input[type=""password""], textarea, select {{width: 100%;padding: 10px;margin-bottom: 20px;border: 1px solid #ccc;border-radius: 4px;}}input[type=""checkbox""] {{margin-right: 10px;}}label {{margin-bottom: 10px;color: #555;}}input[type=""submit""] {{background-color: #28a745;color: #fff;border: none;padding: 10px 20px;cursor: pointer;border-radius: 4px;font-size: 16px;}}input[type=""submit""]:hover {{background-color: #218838;}}</style></head><body><div class=""container""><h1>提交表单</h1><form action=""person-info"" method=""post"" enctype=""multipart/form-data""><label for=""name"">姓名</label><input type=""text"" name=""name"" id=""name"" placeholder=""姓名"" required /><label for=""password"">密码</label><input type=""password"" name=""password"" id=""password"" placeholder=""密码"" required /><label for=""description"">描述</label><textarea name=""description"" id=""description"" placeholder=""描述""></textarea><label for=""gender"">性别</label><select name=""gender"" id=""gender""><option value=""M"">公</option><option value=""F"">母</option></select><label for=""hobbies"">爱好</label><select name=""hobbies"" id=""hobbies"" multiple=""multiple""><option>写小说</option><option>看电影</option><option>打篮球</option></select><div><input type=""checkbox"" name=""married"" value=""Yes"" id=""married"" /><label for=""married"">是否已婚?</label></div><div><input type=""checkbox"" name=""adventurous"" value=""Yes"" id=""adventurous"" /><label for=""adventurous"">是否敢于尝试新事物?</label></div><input type=""hidden"" name=""secretHiddenValue"" value=""保密信息"" /><input type=""submit"" value=""提交个人信息"" /></form></div></body></html>";await context.Response.WriteAsync(page);});app.MapPost("person-info", async context =>{context.Response.Headers.Append("content-type", "text/html;charset=utf-8");if (context.Request.HasFormContentType){var form = await context.Request.ReadFormAsync();foreach (var v in form.Keys){await context.Response.WriteAsync($"{v} = {form[v]} <br/>");}}await context.Response.WriteAsync("");});app.Run();
