netcore url编码/解码

直接上代码

using Microsoft.AspNetCore.Mvc;
using System.Web;

namespace SaaS.OfficialWebSite.Web.Controllers
{
    public class UrlCodeController : Controller
    {
        public IActionResult Index()
        {
            return View();
        }

        [HttpPost]
        public IActionResult Encode([FromBody] UrlEncodeRequest request)
        {
            if (string.IsNullOrWhiteSpace(request.Text))
            {
                return BadRequest(new { error = "输入文本不能为空" });
            }

            try
            {
                string encodedText;

                if (request.EncodeFullUrl)
                {
                    // 编码整个URL
                    encodedText = request.EncodeSpaceAsPlus
                        ? Uri.EscapeUriString(request.Text).Replace("%20", "+")
                        : Uri.EscapeUriString(request.Text);
                }
                else
                {
                    // 仅编码查询部分
                    var uriBuilder = new UriBuilder(request.Text);
                    var query = HttpUtility.ParseQueryString(uriBuilder.Query);

                    if (request.EncodeSpaceAsPlus)
                    {
                        uriBuilder.Query = query.ToString().Replace("%20", "+");
                    }

                    encodedText = uriBuilder.Uri.AbsoluteUri;
                }

                return Ok(new { encodedText });
            }
            catch (Exception ex)
            {
                return StatusCode(500, new { error = "编码过程中发生错误", details = ex.Message });
            }
        }

        [HttpPost]
        public IActionResult Decode([FromBody] UrlDecodeRequest request)
        {
            if (string.IsNullOrWhiteSpace(request.Text))
            {
                return BadRequest(new { error = "输入文本不能为空" });
            }

            try
            {
                // 先替换+号为空格，然后解码
                var decodedText = Uri.UnescapeDataString(request.Text.Replace("+", " "));
                return Ok(new { decodedText });
            }
            catch (Exception ex)
            {
                return StatusCode(500, new { error = "解码过程中发生错误", details = ex.Message });
            }
        }
    }
    public class UrlEncodeRequest
    {
        public string Text { get; set; }
        public bool EncodeFullUrl { get; set; } = true;
        public bool EncodeSpaceAsPlus { get; set; } = false;
    }

    public class UrlDecodeRequest
    {
        public string Text { get; set; }
    }
}
