《ASP.NET Core 知识速递 - Day 3：每天进步一点》 文章中我们讲解了如何更优雅的方式创建编码的url查询字符串，在这节中我们我们使用System.Net.Http.FormUrlEncodedContent类对name/values进行编码并生成一个查询字符串的url，使用的application/x-www-form-urlencoded MIME 类型。
var app = WebApplication.Create();app.Run(async context =>{var dicts = new Dictionary<string, string>(){["id"] = "001",["name"] = "gui bingbing",["birthday"] = "1986/08/30",["guid"] = Guid.NewGuid().ToString(),["artist"] = "Bill Gui",["formula"] = "10 * 5 = 50"};using var queryString = new FormUrlEncodedContent(dicts);context.Response.Headers.Append("Content-Type", "text/html;charset=utf-8");await context.Response.WriteAsync($@"<html><head><link rel=""stylesheet"" href=""https://cdnjs.cloudflare.com/ajax/libs/bulma/0.7.5/css/bulma.css"" /></head><body class=""content""><div class=""container""><h1>使用 FormUrlEncodedContent 创建编码的URL字符串</h1><strong>输入</strong>");await context.Response.WriteAsync("<ul>");foreach (var k in dicts){await context.Response.WriteAsync($"<li>{k.Key} = {k.Value}</li>");}await context.Response.WriteAsync("</ul>");await context.Response.WriteAsync("<strong>输出</strong><br/>");await context.Response.WriteAsync(await queryString.ReadAsStringAsync());await context.Response.WriteAsync("</ul>");await context.Response.WriteAsync(@"</div></body></html>");});app.Run();
运行应用程序：
