Javascript Ajax删除请求&；调用Node/Express-after方法时的响应如何使用GET方法重定向？

我不熟悉AJAX和Node，不知道如何处理： 我有一个deleteAJAX调用，在从db中删除行之后，我想重定向回同一个路由，但是使用GET方法。我相信我也可以从前端脚本重定向页面，我不确定哪种策略是正确的。感谢您的帮助

前端js制作ajax调用script.js

  $('.deleteRepository').on('click', function(event) {    
    event.stopImmediatePropagation();
    var username = $(this).attr('username');
    var repoName = $(this).attr('repoName');
    var oReq = new XMLHttpRequest();
    oReq.open("delete", "/user/"+username+'/'+repoName);
    oReq.send();
  });

router.route('/:username/:repository')
    .delete(function(req, res) {
      console.log('\n\nDelete method called\n\n');
      let username = req.params.username;
      let repoName = req.params.repository;

      deleteRepositoryFromUser(req, res)
        .then(function() {
          console.log('deleted, now redirect');
          //I want to redirect to this page using GET, but logs DELETE
          //I also want to redirect to /user/TonyStark/Favorites
          res.redirect(200, '/user/'+username+'/Favorites'); 
        })

myRoute.js

  $('.deleteRepository').on('click', function(event) {    
    event.stopImmediatePropagation();
    var username = $(this).attr('username');
    var repoName = $(this).attr('repoName');
    var oReq = new XMLHttpRequest();
    oReq.open("delete", "/user/"+username+'/'+repoName);
    oReq.send();
  });

router.route('/:username/:repository')
    .delete(function(req, res) {
      console.log('\n\nDelete method called\n\n');
      let username = req.params.username;
      let repoName = req.params.repository;

      deleteRepositoryFromUser(req, res)
        .then(function() {
          console.log('deleted, now redirect');
          //I want to redirect to this page using GET, but logs DELETE
          //I also want to redirect to /user/TonyStark/Favorites
          res.redirect(200, '/user/'+username+'/Favorites'); 
        })

控制台

GET /user/TonyStark/delMe 200 114.702 ms - 4075
...    

Delete method called


deleteRepositoryFromUser()
repoName: delMe
username: TonyStark
deleted, now redirect
DELETE /user/TonyStark/delMe 200 4.568 ms - 44 //how can I make GET?
//why is it not going to /user/TonyStark/Favorites?

这一行是错误的

res.redirect（200'/user/'+username+'/Favorites'）。代码200不能重定向。您必须使用301或302重定向。在此处查看有关http代码的参考信息：
您还可以在重定向之前手动将http方法设置为GET

在myRoute.js中：

router.route('/:username/:repository')
.delete(function(req, res) {
  console.log('\n\nDelete method called\n\n');
  let username = req.params.username;
  let repoName = req.params.repository;

  deleteRepositoryFromUser(req, res)
    .then(function() {
      console.log('deleted, now redirect');

      //Explicitly set the HTTP method to GET
      req.method = "GET"

      res.redirect(200, '/user/'+username+'/Favorites'); 
    })

谢谢斯瓦贝尔。但是，当我尝试这样做时，它会在循环中不断递归地提交请求。
